Dear all.
We are using Dawn Framework & CDO to generate Editors and store the different models we have in the platform.
I believe that my problem is similar to this one:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=404043#c2
In my case the CDOResourceNodeSelectionWidget tree , instead of Dawn Explorer, does not show resources inside the view.
This class is called from the generated Dawn Model Wizards of my models. I need it working to allow to the user select the destination CDOResourceFolder inside the repository for the model he is going to create. I'm really stucked with this problem and I would be very grateful if anyone could help me.
I'm getting this exception java.lang.IllegalStateException: No node for View 1 [MAIN] in ContainerItemProvider.getChildren() function when trying to expand the View Node.
The Dawn Explorer View is working well.
The version of Dawn I'm using is 2.0.100.v20130503-1908
Best regards.

Hi, Angel,
Have you stepped through the DawnWizardPageItemProvider to see why it
doesn't create a node for your view? It seems to me that this is
similar to bug 404043 and that a similar treatment might help. If you
can create a Bugzilla and supply a Gerrit change, I'd be happy to look
at it.
I wouldn't expect that much has changed in Dawn since the build you
used, but perhaps the CDO infrastructure has changed. Have you tried a
recent Luna milestone (e.g., M7)?
Cheers,
Christian

Hi, Angel,
Sorry for the long delay.
This looks promising. Please raise a Bugzilla:
https://bugs.eclipse.org/bugs/enter_bug.cgi?alias=&assigned_to=emf.cdo-inbox%40eclipse.org&bug_severity=normal&bug_status=NEW&component=cdo.dawn&form_name=enter_bug&product=EMF&version=4.2
and submit a change to Gerrit:
ssh://git.eclipse.org:29418/cdo/cdo.git
I don't know whether this change can be considered for the Luna release
in this RC ramp-down phase or whether it will have to wait for SR1, but
we'll see. Hopefully we can process it sooner.
Cheers,
Christian

+1 for getting it in if you're confident in it ;-)
