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.

In addition, you can provide event handler methods in your page or component classes to handle more complex validation scenarios.</p><p>Finally, Tapestry not only makes it easy to present errors messages to the user, but it can also automatically highlight form fields when validation fails.</p><p><strong>Contents</strong></p><p><style type="text/css">/*<![CDATA[*/

Please always check
on the documentation, or consult the user mailing list, to see if there's a stable, public alternative.

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>

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.
