Interruptible activity regions

I’m drawing a UML activity diagram and can’t seem to be able to drag an exception handler from an interruptible activity region to any action. However, it works fine from one action to another or if I drag a constraint or containment line from the region.

Is this a bug or by design? I’m using VP 6.1.

I’ve seen quite a few UML activity diagrams with the so-called “interruptible edge” from an interruptible region to an action. I’m guessing that this type of edge is supposed to be represented by the exception handler in Visual Paradigm?

Dear Cubah,

According to uml specification, exception handler is for connecting between 2 executable node. But since interruptible activity region is not kind of executable node therefore it is not possible to be connected via exception handler. And in specification, there is only a term interruptible edge exist, but didn’t have any model call interruptible edge. If you require any further information, please do not hesitate to contact me again.

Best regards,
