Q: c:forEach, c:import and variable scope?

[otisg <ot...@ureach.com>]

Hello,

Here is the problem (using [] to avoid problems with email
clients not handling HTML well).

Summary:
c:forEach loop, inside it c:import, but the c:import-ed JSP does
not see the var from the c:forEach loop.

[c:forEach var="foo" items="${bars}"]
  [c:import url="some/page.jsp"/]
[/c:forEach]

In this page.jsp I try to access ${foo}, like so:
[c:out value="${foo}"/]

No go.  ${foo} seems undefined there :(  page.jsp does not see
it.  Scope issue?

I then tried adding the following inside that c:forEach:
[c:set var="newFoo" value="${foo}" scope="request"/]

However, that c:import-ed page.jsp does not see ${newFoo}
either. :(

I am using jakarta-taglibs 1.0.3 with JBoss/Jetty.

Is the above supposed to work?
How do I get the import-ed page.jsp to see a variable defined in
the page that imported it?

Thanks,
Otis

Yup. As Hans said, you need to promote 'foo' to request scope.

Hmm. This works fine for me...
