Subject: Issue - 123 - Matching <reply> with <receive>
This issue has been added to the wsbpel issue list. 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 document with the title in the "Issues" folder of the WSBPEL TC document list - the next posting will include this issue. The list editor's working copy, which will normally include an issue when it is announced, is available at this constant URL.
The rule of matching a reply activity with a receive activity is not clearly defined in the current specification.
Discussion:
The current specification is not defined clearly enough to answer the following questions.
[Q1] Must <reply> always specify all the correlation sets specified by the corresponding <receive>?
For example, if there are two <receive>'s outstanding as follows,
receive name="rec1" partnerLink="pl" portType="pt" operation="op" correlation set="cs1" initiate="no" correlation set="cs2" initiate="no" correlation set="cs3" initiate="yes" correlation set="cs4" initiate="yes"receive name="rec2" partnerLink="pl" portType="pt" operation="op" correlation set="cs1" initiate="no" correlation set="cs2" initiate="no" correlation set="cs5" initiate="yes" correlation set="cs6" initiate="yes"
Must a <reply> specify all of the corresponding <receive>'s CS's? That is, for rec1,
reply name="rep1" partnerLink="pl" portType="pt" operation="op" correlation set="cs1" initiate="no" correlation set="cs2" initiate="no" correlation set="cs3" initiate="no" correlation set="cs4" initiate="no"
Or only as many as necessary to disambiguate the matching?
reply name="rep1" partnerLink="pl" portType="pt" operation="op" correlation set="cs3" initiate="no"
[Q2] Does it follow that if a <receive> specify a correlation set, the corresponding reply can only send a message that contains the correlation set?
If it does, then the rule seems to be too restrictive. For example, the following process will be illegal.
