Somewhere i read, that it's possible with Cayenne to have relationships connecting entities from two different DataMaps, just like WebObjects EOModeler. I am not able to create such relationship in Cayenne Modeler 4.0RC1 and 4.1M2 - the target entity dropdown lists only entities from the current map. Any hints?
See screenshot Apache CayenneModeler
You can create DbRelationship first and use it. In this case you can choose any DbEntity in any DataMap. See this tutorial for details.
