[5.4] Render Partial HTML Pages
Dear Tapestry Developers / Users,
I have a question concerning partial HTML rendering without using zones using 5.4. Until alpha 24, the following code was working:
@Inject private Block page;
@Inject private Block modal;
public Object getActiveBlock() {
return request.isXHR() ? modal : page;
}
The modal block consists of a <div> element. Using plain jQuery or http://pjax.heroku.com/ I was able to replace parts of the page with the HTML snippet rendered by T5. The good thing is, that the entire page is loaded in case of a normal request and the partial HTML is very easy to debug.
The part of the code which prevents the rendering now is in DocumentLinkerImpl:
// This only applies when the document is an HTML document. This may need to change in the
// future, perhaps configurable, to allow for html and xhtml and perhaps others. Does SVG
// use stylesheets?
if (!rootElementName.equals("html")) {
throw new RuntimeException(String.format("The root element of the rendered document was <%s>, not <html>. A root element of <html> is needed when linking JavaScript and stylesheet resources.", rootElementName));
}
My question: is there a way to render partial HTML pages without using zones or decorate the DocumentLinker service?
What about introducing a Symbol which allows partial HTML rendering? If you're interested I can submit a pull request.
Thanks and best regards,
Thilo

Hi all, hi Thiago
a quick update from my side concerning the partial page rendering issue, just in case anyone facing the same problem.
Instead of modifying the DocumentLinker, I created a BlockRenderer service which is able to render injected Block objects as a stream response. The reason for this decision is, that the DocumentLinker keeps track of all necessary style-sheets and scripts (for example if the block contains additional scripts). Therefore modifying the DocumentLinker could lead to undesired side effects and could eventually break the zone feature.
Reference how to render a block:
http://apache-tapestry-mailing-list-archives.1045711.n5.nabble.com/Howto-render-a-block-and-put-it-into-a-JSON-reply-tp5486823p5717877.html
The problem is, that this solution uses T5 internals and which are subject to change.
There is already an associated ticket in JIRA:
https://issues.apache.org/jira/browse/TAP5-1864

Hi Thiago,
thanks a lot for your feedback. The application is based on Bootstrap 3 and therefore I enabled the core stack by default.
I will therefore create a patch and file a JIRA issue.
Best regards,
Thilo

Hi!
Does your page import stylesheets or JavaScript directly? Or through
components it uses? If the answers are "no", you can disable the addition
of the core stack. Since alpha 24, there's a symbol for that:
SymbolConstants.INCLUDE_CORE_STACK (tapestry.include-core-stack), which
defaults to true.
Otherwise, I think we can solve this in Tapestry itself by adding some way
to disable DocumentLinker from working in a given request. Please file a
JIRA about it.
