Description Federico Tomassetti

2011-10-19 03:50:01 EDT

Build Identifier: 

When the method view.getRootResource() is invoked sometimes an exception is thrown because a metamodel is not registered.

(org.eclipse.emf.cdo.common.util.CDOException: Generated packages locally not available: CDOPackageUnit[id=http://www.eclipse.org/emf/CDO/Eresource/4.0.0, state=PROXY, type=UNKNOWN, originalType=NATIVE, timeStamp=2011-10-14 11:32:20.183])

The problem disappears registering manually the metamodel.

(see discussion starting with http://www.eclipse.org/forums/index.php/mv/msg/203918/651989/#msg_651989)

Reproducible: Sometimes

Steps to Reproduce:
1. Start the server
2. Insert an object using a metamodel of your choice 
3. From another program try to access the root of that resource

Consider using the solutions proposed in:

https://bugs.eclipse.org/bugs/show_bug.cgi?format=multiple&id=252956

Invoking:

session.options().setGeneratedPackageEmulationEnabled(true); 

solve the problem.

Maybe that should be the default.
