Description Felix Rieger CLA 2011-06-22 09:33:49 EDT 
According to the model, both IndependentUnit and PriorityUnit can contain 0..* subUnits. However, executing IndependentUnits or PriorityUnits containing 0 subUnits will not work, i.e. execute() returns false.
(Executing an empty SequentialUnit, however, returns true.)

This should be fixed, either by changing the model to require at least 1 subUnit (see bug 348220), or by returning true when executing empty IndependentUnits or PriorityUnits.
Comment 1 Felix Rieger CLA 2012-02-02 05:50:49 EST 
This behavior is intentional.
