CallOperation actions, action pins and exceptions

[Uffe]

Hi all,


If I create a CallOperation, regardless of whether I've assigned an operation to it, I can't create my own action pins for it. That's OK, the intent is that CallOperation actions should be linked to operations, and the "Synchronize with Parameters" function in the properties dialog (in the Call tab) allows me to create pins for the operation's parameters.

But what if I want to create a pin for an exception?

An operation's parameters cannot be exceptions. There's no exception property to select. What you can do is add "raised exceptions" to the operation in the properties dialog, Redefines tab.

An action pin, on the other hand, can be an exception. There's an "Exception" property on a pin, and selecting it causes the pin to be displayed differently in diagrams (with an added triangle).

See where I'm going?

I can't manually add pins to a CallOperation action.
The CallOperation action's "Synchronize with Parameters" only creates action pins for the operation's parameters, not for its raised exceptions.
Pins can be exceptions, but operation parameters can't.

So.

How do I represent visually the call to an operation which throws exceptions?
