Exception while retrieving attribute _display for portlet
Jetspeed is from the current CVS, Tomcat 3.3m3
I am seeing the following error in jetspeed.log. I believe is occurs
when the user enters the customizer.

Is this the correct place to post the type of message, i.e. stack trace
related to code under development?
