Title: State Transitions
Post by: sbaldrick on September 16, 2011, 08:53:15 am

In the Transition Properties dialogue window, one may specify the effect as behavior and select that behavior from a list of class operations.

In the dialogue window there is room for selection of several behaviors, yet each time I select another behavior it replaces the existing behavior instead of adding to it.

It is normal for a state transition to trigger several operations. It should be possible to select several behaviors describing those operations.

Leslie,

I believe it is indeed a UML restriction that a transition can have at most one behavior as effect.
So I guess EA is just (trying) to be UML compliant. (an Operation is not a Behavior, so they are still wrong here)

Behavior/Operation - I may have mixed up the terms a bit.

As an example, a state transition may cause many triggers to be fired in addition to performing 1 (or more) operations within the current object.

The easy workaround is to create an operation that performs the complete behavior of the transition, but this seems a little awkward, and doesn't help clarify the requirements.
