I have resolved the issue for our implentation by modifying the org.apache.jetspeed.

The excpected impact will be that any navigation away from the current portlet will result
in the mode being returned to the normal state. 

This resolves our issue where the left navigation bar links to role/group psml's, which were
broken when/if portlet was maximized, and a user navigated away from the maximized portlet.

I'd appreciate any comments on how/if the code adjustment above may impact other components
of jetspeed.

    Summary: JSP Maximizing a Portlet, and navigating away from Portlet yields <> in

When maximizing a portlet, and navigating away from the maximized portlet, the new page has
the layour (header, left and footer), but the portlet space contains:

I did see postings from 1.4b3, which indicates a possible fix for similar issue, however,
I'm not sure if the fixes were incorporated, or if this is a different issue

After Maximize Protlet, buildNormalContext not Called

After further investigation, your comments make sense.  There seems to be a
bug in the way Jetspeed 1.4b3 handles a portlet when it is maximized,
restored or minimized.  After digging around and outputting rundata, saw
that when you maximized a portlet, the js_peid is set to the portlet that is
maximized.  When you then select a link off of that page to go to a
completely different psml, the Jetspeed:pane tag lib is called, it checks to
see if the js_peid is set, if so, then it uses that value to look for a
portlet in the psml file, if it is not set then it uses the name to locate
the portlet.  Since the psml does not have any portlets with that js_peid,
we get the blank screen.

The solution was to modify the MAXIMAZE, RESTORE and MINIMIZE classes along
with the pane taglib class.  Added a new key,value pair to the temp storage
to control the behavior.
