NPE in Management Portlet
Hi all,
I hope someone can help, and I apologize if the answer to my query is in a JIRA issue/WIKI page/forum post/doc that I have missed, but my management portlet isn't working in 2.2.0, 2.2.1RC2 or from HEAD (2.4.0ALPHA ?).
Here are my environment details:
MySql 5 (with Truncation fixes applied)
JBoss 4.0.3SP1 from source built against jdk 1.5_06
Configured against localhost:8080
When I first load the management page, no links in the management portlet respond to any click. The screen just flashes, and there is no change in the portlet contents.
If I maximize the management portlet (by clicking it) it disappears completely and I get the following NPE stack trace in the console:
15:47:27,125 ERROR [[/portal-core]] Exception in FacesServlet

Then - if I click the back button in the browser twice the Management page will appear, (not maximized) and if I click any link in the management portlet, it draws 'maximized' and appears to start working correctly.
If I navigate off of the management page at this point, then it will not draw at all again -- instead producing the same NPE exception stack trace as above on any request, until I log out of the portlet and log back in again.
This behaviour is consistent no matter what build I've used (from binary, from source, from CVS), bundled or not.
I'd appreciate any help anyone can offer - thanks,
Colin
