MagicDraw/Cameo: GOTCHA: ‘entry’, ‘exit’, ‘doActivity’ are all subsets of ‘ownedElement’; to use an existing Activity without changing its owner you need to create a “wrapper” Activity. Beware the tool does not simply move your Activity!

[TOOL, WARNING]{INFORMATIVE} MagicDraw/Cameo: GOTCHA: ‘entry’, ‘exit’, ‘doActivity’ are all subsets of ‘ownedElement’; to use an existing Activity without changing its owner you need to create a “wrapper” Activity. Beware the tool does not simply move your Activity!
Snippets (quotes/extracts)
  [UML-2.5.1] A State may have an associated entry Behavior. This Behavior, if defined, is executed whenever the State is entered through an external Transition.
  [UML-2.5.1] In addition, a State may also have an associated exit Behavior, which, if defined, is executed whenever the State is exited.
  [UML-2.5.1] A State may also have an associated doActivity Behavior. This Behavior commences execution when the State is entered (but only after the State entry Behavior has completed) and executes concurrently with any other Behaviors that may be associated ...
  [UML-2.5.1] ... if a doActivity Behavior is defined for the State, this Behavior commences execution immediately after the entry Behavior is executed. It executes concurrently with any subsequent Behaviors associated with entering the State, such as the entry ...
  [UML-2.5.1] When exiting a State, regardless of whether it is simple or composite, the final step involved in the exit, after all other Behaviors associated with the exit are completed, is the execution of the exit Behavior of that State.
  [UML-2.5.1] If the State has a doActivity Behavior that is still executing when the State is exited, that Behavior is aborted before the exit Behavior commences execution.
