Description Mark Gruener 2002-01-30 15:32:26 UTC 
I had a properties file open in the NetBeans editor.
I deleted it with the NT file manager.
Went back to NetBeans and got a null pointer...

Comment 1 Jan Lahoda 2002-01-30 17:14:30 UTC 
This seems to be problem of properties files support (and therefore
properties module). Reassigning to it.

Comment 5 Ben Hutchison 2002-03-13 10:12:17 UTC 
This issue is really hurting me! Please provide a patch or workaround 
ASAP.

Because of this issue, I cannot currently:
1. Change projects (*most important*)
2. Shutdown IDE
3. Close "infected" properties editor tabs

1. in particular is critical functionality.
Comment 6 Martin Roskanin 2002-03-13 10:29:02 UTC 
Please, use a patch attached in the issue #19842.

I am sorry, that I didn't let you know about the patch yesterday.

Thanks,
Mato
