In a Domain Model, I am trying to make a reference (with left hand role cardinality Max=1 Min=0) from a connector showed as a class and another class of the domain model. And at debugging, when I introduce the value of the class in the property grid an exception is showed displaying "Property value is not valid, an internal error was occurred".
Is not possible to do associations between connectors class and another classes in a DomainModel?
On the drawing surface, we don't currently have a way of making connectors to or from connectors; but the underlying Store handles this properly, or should do; and the Properties Grid should display it properly, and allow it to be set.
I'll log a bug for this and it should get fixed in the next release or two.
BTW, value-properties on relations should work OK.
