Description Milos Kleint 2007-07-04 13:21:00 UTC 
using 5.5.1 on linux, jdk 1.5

Steps to reproduce:
1. start IDE, add a glassfish/app server instance in Server Manager
2. create a Web project and associate it with the created app server instance.
3. remove the app server instance in Server manager
4. restart IDE, it complains about wrong reference to server. Ignore that for now.
5. find the sun-web.xml file in Configuration files and double-click on it. results in the exception below.

While the project is obviously in an invalid state, one should not have DataObjects and the visual representation in the
IDE tied to the project state. Or at least it shall fail gracefully, nto with exception.

Comment 1 Milos Kleint 2007-07-04 13:22:11 UTC 
oh, and I haven't tested with 6.0, just 5.5.1.
Comment 2 _ pcw 2007-07-05 20:19:06 UTC 
This issue affects 5.5.1 (and probably 5.5) only.  It does not affect 6.0.

Visual state of the configuration editor is tied to the server because of JSR-88.  That is why it is managed by the
configuration object.

But this NPE is just a bug.  It is trivial to fix and was identified when 5.5 was in high resistence mode.
