Add a class diagram to another class diagram using RSA API   

Hi,

I'm trying to add a class diagram link to another class diagram using RSA extension api (programmically). In RSA IDE, I can just drag and drop another class diagram into a class diagram; when I double-click this class diagram (link), RSA will open that class diagram for me.

I had tried to use UMLDiagramHelper.createNode(cd, "DiagramName"); but having problem to assign the target class diagram to this new created node.

Any idea?

Thanks
Maniel
