Issue - 85 - Multiple links with the same source and target

Status: open
Date added: 17 Nov 2003
Submitter: Dieter Koenig
Date submitted: 16 November 2003
Document: BPEL4WS 1.1 (May 5, 2003), Section 12.5, "Flow"
Description: In the BPEL4WS 1.1 specification of May 5, 2003, Section 12.5, "Flow",
introduces the flow activity, contained link elements, and defines constraints for
referring to links in activity standard elements source and target. The specification
allows multiple links to have the same source and the same target. There is no need
to allow this. The referred conditions may easily combined into one. Example:
   <flow ...>
     <links>
       <link name="AtoB-1"/>
       <link name="AtoB-2"/>
     </links>
     <invoke name="A" ...>
       <source linkName="AtoB-1" transitionCondition="P1"/>
       <source linkName="AtoB-2" transitionCondition="P2"/>
       ...
      </invoke>
     <invoke name="B" ...>
       <target linkName="AtoB-1"/>
       <target linkName="AtoB-2"/>
       ...
     </invoke>
   </flow>

Submitter's proposal: Add an explicit constraint to the specification text that
disallows multiple links to have the same source and the same target.
