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

Oh, and I forgot to mention that questions about CDO/Dawn should be
directed to the EMF newsgroup (eclipse.tools.emf), not EMF Technology,
because CDO is in the EMF project.

Dear Christian
We are using Kepler, move to Luna would need to many effort. We have the experience of moving from Juno to Kepler, the project began in 2011.
To solve the problem i have changed the code of DawnWizardPageItemProvider.getChildren() for this one based in the code of DawnItemProvider.getChildren() used by the Dawn Explorer that works well.
@Override
public Object[] getChildren(Object element)
{
Object[] result = super.getChildren(element);
if (result.length > 0 && result[0] instanceof CDOView)
{
result = new Object[] { result[0] };
return result;
}
if (element instanceof CDOResourceFolder)
{
return ((CDOResourceFolder)element).getNodes().toArray();
}
return result;
}
Many thanks for your help.
Best regards.

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 ;-)
