Subject RE: [J1] Forward Service Problem
Date Tue, 03 Feb 2004 14:18:32 GMT
Thanks for response.

I got around this for now by forwarding to the maximized state of the same
portlet and changing the template in build method.

This is not the perfect solution as you can see, because I have to invoke
the buildNormal from buildMax just to make sure that I have all the data for
the maximized detail.

I will try to put a sample PSML together and mail it to you.

Thanks

Dmitry

Im also finding that putting the pane or peid in the session to track 
navigational state can be problematic.
Regarding your forwarding problem, I think it would be best if you sent 
me some sample PSML and your forward XML
I will then try to debug it
