NPE in Eclipse Portlet Creation Wizard

New Member Publications: 7 Date d'inscription: 26/08/08 Publications récentes
Hi,

I'm new to liferay and am trying to create my first portlet using the ext environment and the Eclipse plugin. I'm using Eclipse 3.3. I have a new ext project in eclipse and I'm trying to add a portlet using the wizard. The wizard dialog displays fine, I pick the project from the dropdown, and provide the name of the portlet I want to create. So far so good. When I click the "Finish" button nothing happens - i.e., the dialog stays open and waiting. I opened the eclipse Error view and the following exception is logged. Any ideas?

Thanks,
Rich

...Just noticed that the portlet was created in spite of the NPE. There are directories and files under WEB-INF and html. To my untrained eyes it looks like everything is there. Hmmmm..

Thanks,
