Subject: [wsbpel] Issue - R8 - Revised Proposal
Hi all, Proposal for Vote [take 4] [Factoring in Dieter's rewording suggestion and Danny's paragraph flow concern by moving some sentences out of the bullet list] The follow changes applies to in Bullet 4 of Section12.7: (changes are highlighted in GREEN) ============================
----------------------------- <scope name="P"> <faultHandler> <catchAll> <scope name="FH_P"> <sequence> ... <compensate /> ... </sequence> </scope> </catchAll> </faultHandler> <sequence> ... <scope name="Q" isolated="true"> <compensateHandler> <sequence name="undoQ_Seq"> ... </sequence> <compensateHandler> <sequence name=doQ_Seq"> ... </sequence> </scope> ... </sequence> </scope> ----------------------------- In the above example, the <compensate/> activity is NOT already within an isolation domain (say assuming scope "P" is the root scope of the process). The execution of the CH of scope-Q will be isolated automatically. This isolation domain ends when the execution of the CH of scope "Q" ends. The compensation handler associated with a non-isolated scope actually shares the isolation domain of the invoker of the compensation handler, when the invoker is already within an isolation domain. (See scope "FH_X" in the following examples.) ----------------------------- <scope name="X"> <faultHandler> <catchAll> <scope name="FH_X" isolated="true"> <sequence> ... <compensate /> ... </sequence> </scope> </catchAll> </faultHandler> <sequence> ... <scope name="Y"> <compensateHandler> <sequence name="undoY_Seq"> ... </sequence> <compensateHandler> <sequence name=doY_Seq"> </sequence> </scope> ... </sequence> </scope> ----------------------------- In the above example, the <compensate/> activity will invoke the compensationHandler of scope "Y" (which performs sequence "undoY_seq") in the isolation domain of scope "FH_X". ============================ Regards, Alex Yiu |
