Antonio Petrelli resolved TILES-337.
------------------------------------
Resolution: Won't Fix
Things put in <tiles:putAttribute> tag are evaluated in the page where they are
defined, not in the page in which they are included.
This is how JSP pages work.
The workaround is using the <%include> directive (not the <jsp:include> tag).
> putAttribute does not render inline dynamic content (jsp) correctly

> Use case: Post to jsp1 a couple of times with different http param values for
> the parameter 'foo'. Then do the same for jsp2 and jsp3.
> Results:
> - jsp1.jsp renders correctly
> - jsp2.jsp renders correctly
> - jsp3.jsp renders incorrectly after the second or third request. Subsequent
> posts result in the second param.foo value being stale (keeps a value from an
> earlier http post) and not matching the first param.foo value.
> I would like to in-line jsp inside the putAttribute start/end tags but it
> seems to only handle dynamic content for a request or two. Is this a bug or
> is in-line dynamic content not supported? It would be a shame to have to add
> an extra include file for every attribute with dynamic content.
> I have also tried substituting the jstl el expression in jsp3 with
> <%=request.getParameter( "foo" ) %> as well as trying various values for the
> putAttribute "type" attribute and got the same results.
> Thanks for all the help,
> Ken
