Exception line usage

I’m trying to depict an exception handler. I’ve place an action node, and two accept event nodes, all enclosed by an interruptable activity region. Outside theregion are to action nodes. When I try to connect an event node to an outside action (handler) I can’t. I get the red circle with a slash symbol.

How can I do this?

The exception handler should be connect to the input of the target element. (see below)
