Copy-Paste Feature Not Working about spray HOT 2 OPEN

The problem is, that the current generation of the copy feature assumes that 
the domain model element mapped to Diagram is a super class of all other domain 
model elements used in the other mappings. Thus e.g. the copy feature in the 
LWC example works as there this structure has been used.

In the Busmode example BusinessDomainModel is not a super class of 
BusinessClass therefore the copy feature doesn't work here.

I will change the generation so that there several instance of checks will be 
performed (or I just check the package).

Maybe it is not a idea to enable copy feature by default (deep copy issue):
