CCing myself.
Comment 3 Jesse Glick 2001-09-23 18:20:54 UTC 
This is duplicate of a bug which just got assigned to me (P3,
curiously) and which I reassigned to the editor. Can't remember the #
offhand.

Comment 5 Jan Zajicek 2001-09-24 11:23:03 UTC 
Yarda and Vita discussed this and the resolution was, that this should
be fixed in data systems by returning the node or by returning new
dummy/void node. It is P1 because this exception occurs in many
modules and we cannot guarantee that after isValid will be the
dataobject valid - someone can still invalidate it in multithreading
environment.
Comment 6 Vitezslav Stejskal 2001-09-24 12:43:06 UTC 
I will apply the change with *void node* as a hot fix, but this need 
wider discussion on openide-dev (I'll try to start it).
Comment 7 Vitezslav Stejskal 2001-09-24 16:22:21 UTC 
After some investigation I found that this problem was 
resolved by fixing issue #15795. In fact this wasn't caused by race 
conditions but missing validity check in 
...editor.DORegistryListener.addSavedSourcesToParserDB ().

It doesn't mean that throwing ISE from getNodeDelegate() called on 
invalidated DO shouldn't be changed in the future, but at least for 
now this restrictive approach helps us to discover problems caused by 
missing checks like this one. Problems casued by race conditions 
theoreticaly exist but they seem occur rarely if whatever (at least 
all similar issues were resolved by adding reasonable validity 
checks).

Vito, can you check also duplicated issue #15813. If it need to be
fixed in EJB, let me know. Thanks.
