Description Radko Najman 2003-03-03 14:53:38 UTC 
Some change (probably in nodes or explorer)
between NB 3.4.1 and 3.5 affects behaviour of the
Database Explorer module.

Scenario:
1. Start the IDE.
2. Create database connection in the Database
Explorer. Connection node will appear under the
Databases node on the Runtime tab.
3. Enable any disabled module.
4. Try to create another database connection.
Conection will not appear under the Databases
node. It will be displayed after the restart of
the IDE.

The problem is that the connection and its node
are created but not displayed. If I use the same
version of the Database Explorer in NB 3.4.1 it
works, if I use it with dev build it doesn't work.
The code is the same but the behaviour is
different, that's why I think it was caused by any
openide change.

If you are aware of any openide change which I
should reflect in my code, let me know, please.

reassigned to nodes subcomponent for evaluation.
Comment 2 Petr Hrebejk 2003-03-04 10:09:50 UTC 
I'm sorry I don't think this is bug in nodes. Could you please 
provide some debug info or test case e.g. which property is fired
and not reflected in the explorer etc.
Comment 3 Radko Najman 2003-03-04 16:37:06 UTC 
It seems the bug was caused by changes in
org.openide.nodes.ChildrenArray class between revisions 1.8 and 1.9.
Method isInitialized() returns different values between these
revisions. Is looks like ChildrenArray lost the associated nodes.

I will implement a workaround for Database Explorer module to prevent
this behaviour until the real source of the problem is fixed. New
issue against openide/nodes will be filed.
Comment 4 psuk 2003-03-04 17:09:36 UTC 
Changing the milestone to NB35, it needs to be fixed for this release,
at least as a workaround in Database Explorer module.
Comment 5 Radko Najman 2003-03-04 19:26:11 UTC 
Workaround implemented.
Comment 6 ssffleming 2003-03-10 20:36:12 UTC 
I am reopening this bug because 4824404 is not fixed
and was closed as a dup of this bug.  Corporate policy
is such that bug 4824404 cannot be reopened when closed
as a duplicate.  My understanding is the EE development
wants a fix implemented in Netbeans and is not willing
to do a workaround.
Comment 7 Radko Najman 2003-03-12 14:16:47 UTC 
Closing. The right issue for the described bug is #31658. Track that
issue for the progress.
