Hello,
Can't you just, hum, choose the containment feature for the problem top level node from those available in the metaclass chosen for diagram element or in one of its super classes?
You may have to post some more details here, otherwise the warning message you are getting just precisely describes the problem you have.

Hello,
I apologize for the delay...
Please consider the situation in more details:
For our Multi-agent system model, we have various diagrams like Agent diagram, Collaboration diagram, Behavior diagram, etc. In Eclipse Helios there were no errors. However, using Eclispe Indigo, for some of the diagrams there are errors. Getting more into the details, one could understand that the errors have occurred only in the following scenario:
If the containment feature of any of the Top Node Reference of the GMF Mapping for a diagram is something other than MultiagentSystem.agent or MultiagentSystem.behavior or MultiagentSystem.... (i.e. something without a direct link to the root element which is MultiagentSystem)
For example, the containment feature of one of the Top Node References in the Collaboration diagram is Organization. ... instead of MultiagentSystem. ... (the root element. ...) which has probably been expected and thus has caused the following errors:
'Containment Feature' must reference the same class or super type of 'Domain Meta Element' of the referenced node
Node label meta features must be owned by the node 'Meta Class' or its super-classes
Top level node 'Containment Feature' must be available in the diagram 'Domain Element' or its super-class
It would be unreasonable if one is forced to always relate everything with a direct link to the root element of the diagram, i.e. MultiagentSystem in our case.
Any help is appreciated. Thanks in advance.
Best regards.

Updates: (For anyone who is experiencing the same problem)
1. Please follow up the issue here:
http://www.eclipse.org/forums/index.php/t/293896/
2. What I already reported regarding the occurrence of this issue only in Eclipse "Indigo" is not true. After doing a fresh installation of "Helios" it turned out that it also happens in Helios. Moreover, in the latest release of Eclipse, i.e. Juno the situation is the same.
So, it is not a problem of Eclipse, but it is rather a constraint of GMF for the containments in our semantic models which we should follow to resolve the error.
Finally, even if you do not resolve the error, you just get a warning for generating the diagram code, but by ignoring that warning you could generate the code and there would be no serious problem at all. However, you would need to then manually modify the generated code and mark those methods as @generated NOT. Please see the above mentioned link for more information.
