Subject: Re: [wsbpel] Issue - 249 - Can multi-start with correlations use implicitcorrelation?
+1 (the example must not be rejected). The current wording for start
activities which requires that "all such activities MUST share at least one
common correlationSet" needs to be aligned with the fact that correlation
sets are always optional.
In addition, when (portable) WS-BPEL correlation sets are used concurrently
with other (non-portable) correlation mechanisms then an explicit statement
should be made that in case of conflicts WS-BPEL correlation sets take
precedence over other correlation mechanisms. With that, the statement
should be modified in the following way:
If a process has multiple start activities with correlation sets then all
such activities MUST share at least one common correlationSet and all
common correlationSets defined on all the activities MUST have the value of
the initiate attribute be set to "join".

This issue has been added to the wsbpel issue list with a status of
"received". The status will be changed to "open" if a motion to open the
issue is proposed and that motion is approved by the TC. A motion could
also be proposed to close it without further consideration. Otherwise it
will remain as "received".
The issues list is posted as a Technical Committee document to the OASIS
WSBPEL TC pages on a regular basis. The current edition, as a TC document,
is the most recent version of the document entitled in the "Issues" folder
of the WSBPEL TC document list - the next posting as a TC document will
include this issue. The list editor's working copy, which will normally

Issue - 249 - Can multi-start with correlations use implicit correlation?
Status: received
Date added: 21 Mar 2006
Categories: correlation
Date submitted: 21 March 2006
Submitter: Danny van der Rijn
Description: Currently: If more than one start activity is enabled
concurrently, then all such activities MUST share at least one common
correlationSet (see Correlation and the Multiple Start Activities example).
If a process contains exactly one start activity then the use of
correlationSets is unconstrained.
Scenario:
<flow>
<receive createInstance="yes"/>
<receive createInstance="yes"/>
</flow>
This is legal, and uses implicit correlation. Adding unrelated correlations
to it:
<flow>
<receive createInstance="yes">
<correlation set ="foo" initiate="yes"/>
</receive>
<receive createInstance="yes">
<correlation set ="bar" initiate="yes"/>
</receive>
</flow>
Is illegal according to the current text. IMO this is inconsistent with our
previous resolutions.
