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
