Comment 2 Denis Anisimov 2006-07-18 15:10:36 UTC 
There are two issues actually in this bug.

One - ClassCastException.
It appears when user open editor but don't change BPEL file.
It seems this is origiannly bug inside NB InstanceContent implementation .
I don't want to start discussion about this problem with NB gyus, so I just 
put into InstanceContent fake objec. The problem with InstanceContent it seems 
appear when one tries to delete smth. but InstanceContent is empty. When
InstanceContent has some object inside it then all is ok. And there is no
methods in InstanceContent that can be used for query its non-emptiness.

The second - NPE. It appears when user dosn't open at all editor for BPEL.
In this case InstanceContent was not initialized via lookup bootstrapping.
And trying to remove smth from null instance of InstanceContent cause NPE.
One need to check initialized InstanceContent before add/remove smth to/from it.

Both issues are fixed.
