</div><h2 id="FormsandFormComponentsFAQ-Whatisthet:formdatahiddenfieldfor?">What is the <code>t:formdata</code> hidden field for?</h2><p>In Tapestry, rendering a form can be a complicated process; inside the body of the Form component are many of field components: TextField, Select, TextArea, and so forth. Each of these must pull data out of your data model and convert it to the string form used inside the client web browser. In addition, JavaScript to support client-side validation must be generated. This can be further complicated by the use of Loop and If components, or made really complicated by the use of Block (to render portions of other pages: this is what the BeanEditForm component does).</p><p>Along the way, the Form is generating unique form control names for each field component, as it renders.</p><p>When the client-side Form is submitted, an event is triggered on the server-side Form component. It now needs to locate each component, in turn, inform the component of its
control name, and allow the component to read the corresponding query parameter. The component then converts the client-side string back into a server-side value and performs validations before updating the data model.</p><p>That's where <code>t:formdata</code> comes in. While components are rendering, they are using the FormSupport environmental object to record callbacks:</p><div class="code panel pdl" style="border-width: 1px;"><div class="codeHeader panelHeader pdl" style="border-bottom-width: 1px;"><b>FormSupport.java (partial)</b></div><div class="codeContent panelContent pdl">

</div><h2 id="GeneralQuestions-HowdoIgetstartedwithTapestry?">How do I get started with Tapestry?</h2><p class="confluence-link">The easiest way to get started is to use <a class="external-link" href="http://maven.apache.org">Apache Maven</a> to create your initial project; Maven can use an <em>archetype</em> (a kind of project template) to create a bare-bones Tapestry application for you. See the <a href="getting-started.html">Getting Started</a> page for more details.</p><p>Even without Maven, Tapestry is quite easy to set up. You just need to <a href="general-questions.html">download</a> the binaries and setup your build to place them inside your WAR's WEB-INF/lib folder. The rest is just some one-time <a href="configuration.html">configuration of the web.xml deployment descriptor</a>.</p><h2 id="GeneralQuestions-WhydoesTapestryusePrototype(inversionsbefore5.4)?WhynotinsertfavoriteJavaScriptlibraryhere?">Why does Tapestry use Prototype (in versions before 5.4)? Why not <
em>insert favorite JavaScript library here</em>?</h2><p>An important goal for Tapestry is seamless DHTML and Ajax integration. To serve that goal, it was important that the built in components be capable of Ajax operations, such as dynamically re-rendering parts of the page. Because of that, it made sense to bundle a well-known JavaScript library as part of Tapestry.</p><p>At the time (this would be 2006-ish), Prototype and Scriptaculous were well known and well documented, whereas jQuery was just getting started.</p><p>The intent has always been to make this aspect of Tapestry pluggable. Tapestry 5.4 includes the option of either Prototype or jQuery, and future versions of Tapestry will likely remove Prototype as an option..</p><h2 id="GeneralQuestions-WhydoesTapestryhaveitsownInversionofControlContainer?WhynotSpringorGuice?">Why does Tapestry have its own Inversion of Control Container? Why not Spring or Guice?</h2><p>An Inversion of Control Container is <em>the</em> key piece of
Tapestry's infrastructure. It is absolutely necessary to create software as robust, performant and extensible as Tapestry.</p><p>Tapestry IoC includes a number of features that distinguish itself from other containers:</p><ul><li>Configured in code, not XML</li><li>Built-in extension mechanism for services: configurations and contributions</li><li>Built-in aspect oriented programming model (service decorations and advice)</li><li>Easy modularization</li><li>Best-of-breed exception reporting</li></ul><p>Because Tapestry is implemented on top of its IoC container, and because the container makes it easy to extend or replace any service inside the container, it is possible to make the small changes to Tapestry needed to customize it to any project's needs.</p><p>In addition – and this is critical – Tapestry allows 3rd party libraries to be built that fully participate in the configurability of Tapestry itself. This means that such libraries can be configured the same w
ay Tapestry itself is configured, and such libraries can also configure Tapestry itself. This <em>distributed configuration</em> requires an IOC container that fully supports such configurability.</p><h2 id="GeneralQuestions-HowdoIupgradefromTapestry4toTapestry5?">How do I upgrade from Tapestry 4 to Tapestry 5?</h2><p>There is no existing tool that supports upgrading from Tapestry 4 to Tapestry 5; Tapestry 5 is a complete rewrite.</p><p>Many of the basic concepts in Tapestry 4 are still present in Tapestry 5, but refactored, improved, streamlined, and simplified. The basic concept of pages, templates and components are largely the same. Other aspects, such as server-side event handling, is markedly different.</p><p>Tapestry 5 is designed so that it can live side-by-side in the same servlet as a Tapestry 4 app, without package namespace conflicts, sharing session data and common resources such as images and CSS. This means that you can gradually migrate a Tapestry 4 app to Tapestry 5
one page (or one portion of the app) at a time.</p><h2 id="GeneralQuestions-HowdoIupgradefromoneversionofTapestry5toanother?">How do I upgrade from one version of Tapestry 5 to another?</h2><p>Main Article: <a href="how-to-upgrade.html">How to Upgrade</a>.</p><p>A lot of effort goes into making an upgrade from one Tapestry 5 release to another go smoothly. In the general case, it is just a matter of updating the version number in your Maven <code>build.xml</code> or Gradle <code>build.gradle</code> file and executing the appropriate commands (e.g., <code>gradle idea</code> or <code>mvn eclipse:eclipse</code>) to bring your local workspace up to date with the latest binaries.</p><p>After changing dependencies, you should always perform a clean recompile of your application.</p><p>We make every effort to ensure backwards-compatibility. Tapestry is mostly coded in terms of interfaces; those interfaces are stable to a point: interfaces your code is expected to implement are usually co
mpletely frozen; interfaces your code is expected to invoke, such as the interfaces to IoC services, are stable, but may have new methods added in a release; existing methods are not changed.</p><p>In <em>rare</em> cases a choice is necessary between fixing bugs (or adding essential functionality) and maintaining complete backwards compatibility; in those cases, an incompatible change may be introduced. These are always discussed in detail in the <a href="release-notes.html">Release Notes</a> for the specific release. You should always read the release notes before attempting an upgrade, and always (really, <em>always</em>) be prepared to retest your application afterwards.</p><p>Note that you should be careful any time you make use of <strong>internal</strong> APIs (you can tell an API is internal by the package name, <code>org.apache.tapestry5.internal). </code>Internal APIs may change <em>at any time</em>; there's no guarantee of backwards compatibility. Please always check
on the documentation, or consult the user mailing list, to see if there's a stable, public alternative. If you do make use of internal APIs, be sure to get a discussion going so that your needs can be met in the future by a stable, public API.</p><h2 id="GeneralQuestions-WhyaretherebothRequestandHttpServletRequest?"><span style="color: rgb(83,145,38);">Why are there both Request and HttpServletRequest?</span></h2><p>Tapestry's Request interface is <em>very</em> close to the standard HttpServletRequest interface. It differs in a few ways, omitting some unneeded methods, and adding a couple of new methods (such as <code>isXHR()</code>), as well as changing how some existing methods operate. For example, <code>getParameterNames()</code> returns a sorted List of Strings; HttpServletRequest returns an Enumeration, which is a very dated approach.</p><p>However, the stronger reason for Request (and the related interfaces Response and Session) is to enable the support for Portlets at some
point in the future. By writing code in terms of Tapestry's Request, and not HttpServletRequest, you can be assured that the same code will operate in both Servlet Tapestry and Portlet Tapestry.</p></div>

</div><p>You may have an existing JSP (or Struts, Spring MVC, etc.) application that you want to migrate to Tapestry. It's quite common to do this in stages, moving some functionality into Tapestry and leaving other parts, initially, in the other system. <a href="request-processing-faq.html">You may need to prevent Tapestry from handling certain requests</a>.</p><h2 id="Integrationwithexistingapplications-HowdoImakeaformonaJSPsubmitintoTapestry?">How do I make a form on a JSP submit into Tapestry?</h2><p>Tapestry's Form component does a lot of work while an HTML form is rendering to store all the information needed to handle the form submission in a later request; this is all very specific to Tapestry and the particular construction of your pages and forms; it can't be reproduced from a JSP.</p><p>Fortunately, that isn't necessary: you can have a standard HTML Form submit to a Tapestry page, you just don't get to use all of Tapestry's built in conversion and validation logic.</p><p
>All you need to know is how Tapestry converts page class names to page names (that appear in the URL). It's basically a matter of stripping off the <em>root-package</em>.<code>pages</code> prefix from the fully qualified class name. So, for example, if you are building a login screen as a JSP, you might want to have a Tapestry page to receive the user name and password. Let's assume the Tapestry page class is <code>com.example.myapp.pages.LoginForm</code>; the page name will be <code>loginform (although, since </code><span>Tapestry is case insensitive, LoginForm would work just as well)</span><span>, and the URL will be </span><code>/loginform</code><span>.</span></p><p> </p><div class="code panel pdl" style="border-width: 1px;"><div class="codeHeader panelHeader pdl" style="border-bottom-width: 1px;"><b>LoginForm.tml</b></div><div class="codeContent panelContent pdl">

It can be due to multiple reasons, some of them below:</p><ul><li>First, check if 'tapestry.js' is present in the head part of your resulting HTML page.</li><li><p>If you have set the <a href="configuration.html">tapestry.combine-scripts</a> configuration symbol to true, Tapestry generates one single URL to retrieve all the JS files. Sometimes, this can produce long URLs that browsers are unable to retrieve. Try setting the symbol to false.</p><div class="confluence-information-macro confluence-information-macro-note"><span class="aui-icon aui-icon-small aui-iconfont-warning confluence-information-macro-icon"></span><div class="confluen

In this case, you should put jQuery on top of the stack and turn on the <a class="external-link" href="http://api.jquery.com/jQuery.noConflict/" rel="nofollow">jQuery.noConflict</a> mode.</li><li>Also, if you have included a custom or third-party JS library on top of the stack that causes the JavaScript parsing to fail, then check the JavaScript syntax in that library.</li><li>If you have used a tool to minimize your JavaScript libraries, this can lead to JavaScript syntax errors, so check if it works with all the JavaScript files unpacked.</li></ul><h2 id="JavaScriptFAQ-What'sthedifferencebetweentheT5objectandtheTapestryobjectinthebrowser?(5.3andearlier)">What's the difference between the <code>T5</code> object and the <code>Tapestry</code> object in the browser?
(5.3 and earlier)</h2><p>Both of these objects are <em>namespaces</em>: containers of functions, constants, and nested namespaces.</p><p>The <code>T5</code> object is a replacement for the <code>Tapestry</code> object, starting in release 5.3. Increasingly, functions defined by the <code>Tapestry</code> object are being replaced with similar or equivalent functions in the <code>T5</code> object.</p><p>This is part of an overall goal, spanning at least two releases of Tapestry, to make Tapestry JavaScript framework agnostic; which is to say, not depend specifically on Prototype or jQuery. Much of the code in the <code>Tapestry</code> object is specifically linked to Prototype and Scriptaculous.</p><p>The <code>T5</code> object represents a stable, documented, set of APIs that are preferred when building components for maximum portability between underlying JavaScript frameworks. In other words, when building component libraries, coding to the <code>T5</code> object ensures that your
component will be useful regardless of whether the final application is built using Prototype, jQuery or something else.</p></div>

</div><h2 id="Limitations-HowdoIaddnewcomponentstoanexistingpagedynamically?">How do I add new components to an existing page dynamically?</h2><p>The short answer here is: <strong>you don't</strong>. The long answer here is <strong>you don't have to, to get the behavior you desire</strong>.</p><p>One of Tapestry basic values is high scalability: this is expressed in a number of ways, reflecting scalability concerns within a single server, and within a cluster of servers.</p><p>Although you code Tapestry pages and components as if they were ordinary POJOs (<span>Plain Old Java Objects -- Tapestry does not require you to extend any base classes or implement any special interfaces)</span><span>, as deployed by Tapestry they are closer to a traditional servlet: a single instance of each page services requests from multiple threads. Behind the scenes, Tapestry transforms you code, rewriting it on the fly.</span></p><p>What this means is that <em>any</em> incoming request must be handled
by a <em>single page instance</em>. Therefore, Tapestry enforces the concept of <strong>static structure, dynamic behavior</strong>.</p><p>Tapestry provides quite a number of ways to vary what content is rendered, well beyond simple conditionals and loops. It is possible to "drag in" components from other pages when rendering a page (other FAQs will expand on this concept). The point is, that although a Tapestry page's structure is very rigid, the order in which the components of the page render does not have to be top to bottom.</p><h2 id="Limitations-Whydoesn'tmyserviceimplementationreloadwhenIchangeit?">Why doesn't my service implementation reload when I change it?</h2><p>Main article: <a href="service-implementation-reloading.html">Service Implementation Reloading</a></p><p>Live service reloading has some limitations:</p><ul><li>The service must define a service interface.</li><li>The service implementation must be on the file system (not inside a JAR).</li><li>The implementati

</div><h2 id="MavenSupportFAQ-WhydoMavenprojectnamesandotherdetailsshowupinmypages?">Why do Maven project names and other details show up in my pages?</h2><p>Tapestry and maven both use the same syntax for dynamic portions of files: the <code>${...</code>} syntax. When Maven is copying resources from <code>src/main/resources</code>, and when filtering is <em>enabled</em> (which is not the default), then any expansions in <em>Tapestry templates</em> that match against Maven project properties are substituted. If you look at the deployed application you'll see that <code>${name</code>} is gone, replaced with your project's name!</p><p>The solution is to update your <code>pom.xml</code> and ignore any .tml files when copying and filtering:</p><div class="code panel pdl" style="border-width: 1px;"><div class="codeHeader panelHeader pdl" style="border-bottom-width: 1px;"><b>pom.xml (partial)</b></div><div class="codeContent panelContent pdl">

</div><h2 id="PageAndComponentClassesFAQ-What'sthedifferencebetweenapageandacomponent?">What's the difference between a page and a component?</h2><p>There's very little difference between the two. Pages classes must be in the <em>root-package</em>.<code>pages</code> package; components must be in the <em>root-package</em>.<code>components</code>. Pages may provide event handlers for certain page-specific events (such as activate and passivate). Components may have parameters.</p><p>Other than that, they are more equal than they are different. They may have templates or may render themselves in code (pages usually have a template, components are more likely to render only in code).</p><p>The major difference is that Tapestry page templates may be stored in the web context directory, as if they were static files (they can't be accessed from the client however; a specific rule prevents access to files with the <code>.tml</code> extension).</p><div class="confluence-information-macro co

Page classes must go in <em>root-package</em>.<code>pages</code>, component classes in <em>root-package</em>.<code>components</code>, etc.</p><p>You are allowed to create sub-packages, to help organize your code better and more logically. For example, you might have <em>root-package</em>.<code>pages.account.ViewAccount</code>, which would have the page name "account/viewaccount". (<span>Tapestry would also create an alias "account/view", by stripping of
f the redundant "account" suffix. Either name is equally valid in your code, and Tapestry will use the shorter name, "account/view" in URLs.)</span></p><p>In addition, it is possible to define additional root packages for the application:</p><div class="code panel pdl" style="border-width: 1px;"><div class="codeContent panelContent pdl">
