User Comments:
jsedek: I just placed a break point at method declaration line

rogerrhody: Changed to an open jsf 2 page (xhtml) by selecting the tab in the editor.  Seem to get these NullPointerExceptions every time I change pages in the editor, I am primarily writing jsf 2 but I also have some persistence classes open and some managed beans.

Comment 2 Daniel Prusa 2009-11-16 04:02:29 UTC 
This is a regression caused by
http://hg.netbeans.org/main-silver?cmd=changeset;node=16b5c55166cb

We have to fix it in 6.8, the NPE could be thrown often and be quite annoying. The fix is not difficult, methods in EditorContextImpl should check whether a given file object is a java source.
