Aggregations result in "ill-formed link across composite boundaries" code generation error

Question & Answer


Question

The model is comprised of the following relations. Note, ModuleA and ModuleB are using aggregations.

This results in the following error when code generation is attempted:
Warning: Link will not be instantiated - ill-formed link across composite boundaries
    in Package: Default
        in Block: BlockA
            connector: BlockA-BlockB

Answer

Aggregation implies that the child (ModuleA/ModuleB) can exist without the composite parent (BlockA/BlockB).

Since the links are created by the composite instance, Rhapsody does not allow aggregation associations in this case.

You must redraw the relations using Compositions:
