Subject: Issue - 188 - Dead Path Elimination and Join Conditions
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 include an issue when it is announced, is available at this constant URL.
<flow suppressJoinFailure="yes"> <links> <link name="first2second"/> <link name="second2third"/> </links> <someActivityname="first"> <sources> <source linkName="first2second"> <transitionCondition> false </transitionCondition> </sources> </someActivity> <someActivityname="second"> <sources> <source linkName="second2third"> </sources> <targets> <target linkName="first2second"/> </targets> </someActivity> <someActivityname="third"> <targets> <joinCondition> not(getLinkStatus("second2third")) </joinCondition> <target linkName="second2third"/> </targets> </someActivity> </flow>
A flow from first to second to third. The transition from "first" to "second" has some condition. If it is false, "second" will not evaluate. Yet according to my reading of the spec this merely sets the link status of "second2third" to false, which in turn causes "third" to execute.
This is in contradiction with my understanding of dead-path elimination.
Submitter's proposal: I would prefer to disallow joinConditions whose
expression does not require a true input in order that the join condition
evaluate to true. Comments?
