Description Srinivasan Chikkala 2008-02-07 18:24:46 UTC 
If you have a xml file with layer filesytem xml content in any project other than nb module project, opening that file
throws the following null pointer exception. In some cases like bpel project, the project view can not show any files
after this exception.

How to reproduce.
1. create a java application or bpel project
2. create a xml file in that project source
3. update the xml file with a sample netbeans layer xml content and save. you get the exception. If you try to open it
also you will get the null pointer exception
