Subject: RE: [wsbpel] Issue - 271 - ConflictingReceive with Different CorrelationSets
Mark, I agree. So the result would be something like this:
Moreover, if a business process instance simultaneously enables two
or more receive activities for the same partnerLink, portType,
operation but different correlationSet(s), and the correlations of
multiple of these activities match an incoming request message, then
conflictingReceive must also be thrown by each of these activities.

RE: [wsbpel] Issue - 271 -
ConflictingReceive with Different
Correlation Sets
I assume that you intend to fault both of the receives with a
bpel:conflictingReceive. This should be made explicit in the spec text.
There is also another case where R1 and R2 contain the same data for their
correlation sets. In this case we could detect the conflicting receive at
the point of execution of the second receive and only fault it.

Subject: [wsbpel] Issue - 271 - ConflictingReceive with Different
Correlation Sets
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 - 271 - ConflictingReceive with Different Correlation Sets
Status: received
Date added: 28 Apr 2006
Date submitted: 28 April 2006
Submitter: Dieter Koenig1
Document: WS-BPEL 2.0 Committee Draft
Description: Section 10.4 defines cases where conflictingReceive must be
thrown:
A business process instance MUST NOT simultaneously enable two or
more receive activities for the same partnerLink, portType, operation
and correlationSet(s).
This definition does not provide the uniqueness required to unambigously
route an incoming request message to the right inbound message activity.
Consider two simultaneously enabled activities (today not a
conflictingReceive because of different correlation sets):
<receive partnerLink="PL1" portType="PT1" operation="OP" ...>
<correlations>
<correlation set="CS1" initiate="no"/>
</correlations>
<receive/>
<receive partnerLink="PL1" portType="PT1" operation="OP" ...>
<correlations>
<correlation set="CS2" initiate="no"/>
</correlations>
<receive/>
In a scenario where BOTH CS1 AND CS2 match an incoming request,
conflictingReceive should also be thrown.
Submitter's proposal: Add text following the sentence quoted above:
Moreover, if a business process instance simultaneously enables two
or more receive activities for the same partnerLink, portType,
operation but different correlationSet(s), and the correlations of
multiple of these activities match an incoming request message, then
conflictingReceive must also be thrown".
