Re: problems tracking session from page to page

[Geoff Howard]

I think the issue is the aggregation.  to test, go directly to the
general.currentproduct pipeline (with the create-session attr. in).
If that works, try to move it to the first map:part if you can as
a workaround.  A better solution would be to look into the session
actions that will ensure you have created your session before the
pipeline starts generating.

hi geoff,

yes, i've tried putting create-session in the xsp:page tag.  but i still get
the IllegalStateException.  as you're probably aware, having create-session
causes the following line to appear at the beginning of the generate()
method:
Session session = request.getSession(true);

that's the line that the exception refers to.

here's a snippet from my sitemap to exemplify one of the two pages where to
problem occurs:
            <map:match pattern="choose_item.html">
                <map:aggregate element="page">
                    <map:part src="cocoon:/choose_item.products"/>
                    <map:part src="cocoon:/general.productcategories"/>
                    <map:part src="cocoon:/common"/>
                    <map:part src="cocoon:/general.currentproduct"/> <!--
only page that accesses session -->
                </map:aggregate>
                <map:transform type="xslt" src="style/choose_item.xsl"/>
                <map:transform type="i18n"/>
                <map:serialize type="html"/>
            </map:match>
does that provide any useful clues?

thanks in advance.
