Having successfully converted a couple of tile JSPs to JSF, I just tried
converting a layout. I'm getting a really weird behaviour which I can't
explain... It *looks* like Tiles is closing the response stream in spite
of flush="false", but if that were the case I'd expect the following
exception to occur sooner in the generated servlet.
Here's the relevant snippet of the layout JSP:
...
<f:subview id="foo">
<!--<t:get name="content" flush="false"/>-->
<t:insert name="content" flush="false"/>
</f:subview>
<jsp:scriptlet>System.out.println("layout 4");</jsp:scriptlet>
<br /><br /><br /><br /><br /><br />
</body>
</s:html>
<jsp:scriptlet>System.out.println("layout 5");</jsp:scriptlet>
</f:view>
</jsp:root>
The exception is thrown from s:view's doEndTag but, looking at the
servlet, I see this:
...
if (_jspx_meth_f_subview_0(_jspx_th_s_html_0,
_jspx_page_context))
return;
System.out.println("layout 4");
out.write("<br/>");
out.write("<br/>");
out.write("<br/>");
out.write("<br/>");
out.write("<br/>");
out.write("<br/>");
out.write("</body>");
}
if (_jspx_th_s_html_0.doEndTag() ==
javax.servlet.jsp.tagext.Tag.SKIP_PAGE)
return;
...
I do see 'layout 4' traced to stdout, so the series of calls to
out.write() must be getting executed and doesn't result in an exception,
as I would expect if the response had been closed at that point. But
there's nothing between them and the call to s:view's doEndTag so,
unless it's the s:view tag that's closing the stream, why do I end up
with an exception?
And if it is Tiles that's closing the response, how do I make it *not*
do that?
Oh, just for completeness, here's the relevant snips of tiles-defs.xml:
<definition name=".core.layout" path="/pages/core/layout.faces">
<put name="title" value="PAGE TITLE"/>
<put name="stylesheet" value="PAGE STYLE"/>
<put name="section" value="SITE SECTION"/>
<put name="content" value="PAGE CONTENT"/>
</definition>
<definition name=".projects.layout" extends=".core.layout">
<put name="section" value="projects"/>
<put name="stylesheet" value="/pages/projects/project-style.css"/>
</definition>
<definition name=".projects.list" extends=".projects.layout">
<put name="content" value="/pages/projects/Projects.jsp"/>
</definition>
And here's the exception:
layout 4
