Issue 6377: AcceptCallAction in SAN (uml2-superstructure-ftf)
Source: International Business Machines (Dr. Tracy Gardner, tgardner(at)uk.ibm.com)
Nature: Revision
Severity: 
Summary: What is the behavior when a SAN contains an AcceptCallAction with no
incoming control links.  Is the accept only enabled once when the SAN
receives a control token, or it it enabled for the lifetime of the SAN?
Either way, how do you model the other behavior.

Resolution: see above
Revised Text: 
Actions taken:
October 20, 2003: received issue
March 8, 2005: closed issue
Discussion: 
Clarify that an AcceptEventAction with no incoming edges in a SAN is enabled for the
lifetime of the SAN, as specified below. Use an AcceptEventAction with incoming
edges To accept only one event, or an interruptible region or exception to terminate the
AcceptEventAction.
In AcceptEventActionClass,
Semantics section:
Third paragraph:
Add to the end of the first sentence:
", whichever most immediately contains the action. In
addition, an AcceptEventAction with no incoming
edges remains enabled after it accepts an event."
Delete the second sentence.
At the end of the paragraph add:
"An AcceptEventAction with no incoming edges and
contained by a structured node is terminated when its
container is."
Examples section:
Delete third sentence, including “(CompleteActions)” at the end.
In StructuredActivityNode, Semantics section, in second paragraph,
at end of first sentence, add:
"(see exception at AcceptEventAction)."
