I carried out the test procedure we have for FAS for MagicDraw ("fas4md-plugin/FAS4MD-v1.0-b05-final-20120116/doc/FAS plugin - verification report template.doc" / "[...].pdf"; via the SVN repository of http://www.sourceforge.net/projects/fas4md/).
Step #45 failed:
Expected: No interface between the blocks "F1" and "F2".
Observed: A connection between blocks "F1" and "F2" is foreseen although the corresponding pins of the object flow are not type compatible.
See the model in the attached ZIP archive.

A type compatibility check (actually, the modeling tool should ensure that pins of an object flow are type compatible!) will be implemented in the upcoming final release 1.0.x.
