Description Girish Balachandran 2006-10-02 21:58:45 UTC

* Take latest release55 build.
* Open netbeans form editor
*  Click on (just) the palette window (Do not click any palette items, just the
window)
* press F1 for context sensitive help and the following NPE occurs. This used to
work before (though it used to show generic help) untill the fix for  	84661
went in. I am opening this as P1 because this is an Exception that is shown to
the user. Evaluate and downgrade if needed. This bug will also affect  	80770.
