Max Andersen commented on JBIDE-1325:
-------------------------------------

btw. your fix does work but I fear it is ignoring a problem about how the project dirs/file dirs are handled which we need to keep an eye on.

I updated svn with a fix that tries to solve some of this but we need to see if it is the *right* fix.

> I'm trying to configure an Eclipse project for WAR deployment to JBoss AS. I go to the "Project Archives" view and create a new WAR configuration via the wizard. It shows up, no problem. Then I try to add a new fileset to the WAR by right-clicking on it and choosing "New Fileset". Nothing happens in the UI, and in the console, I can see a NullPointerException.
