Description _ rkubacki 2004-09-17 10:51:46 UTC 
dev build from Sep 12.

While analyzing INSANE dump I can see some
instances of DataFolder where FolderInstance
object is added as listener twice.

Comment 3 _ rkubacki 2004-09-17 17:01:20 UTC 
It seems that FolderList really triggers duplicated adding of
listeners to most of objects on SFS
Comment 4 David Konecny 2004-09-21 15:04:45 UTC 
Just looking at FolderInstance.defaultProcessObjects() method it looks
that listener is added second time if prevCookie was reset on line 639.

Fixed in:
src/org/openide/loaders/FolderInstance.java
new revision: 1.8; previous revision: 1.7

This issue was solved long time ago. Because nobody has reopened it neither
added comments, we are verifying/closing it now. 
If you are still able to reproduce the problem, please reopen. Thanks in advance.
