How to add logic inside an iterator tag

[Robert Edgar <ro...@hkstar.com>]

What I want to do is display two columns of checkboxes.

The data is fed from a vector(sourced from the DB) and I am using the
iterate tag to generate the checkbox tag inside a TD element.

This works to a degree, however I need to somehow add the TR tag every other
"row" from teh vector but I cant see anyway I can access a counter whilst I
am in the iterator body.

Of course I could just forget the tag and code this up using a normal loop
inside a scriptlet without a problem but I thought there must be someway to
do this in tha tag.

Any thoughts?

Rob

Lines 357-358 of MessageTag say this:

    MessageResources resources = (MessageResources)
      pageContext.getAttribute(bundle, PageContext.APPLICATION_SCOPE);

which cannot throw a null pointer exception itself.  This sounds like a
bug in Weblogic's "weblogic.servlet.jsp.PageContextImpl" class (at line
159).  It sounds like you might be able to use Struts as a test case in a
bug report to BEA.
