I had sent this question to the irc during the meeting before I had to go. Don't know if it got discussed or not.

point (2) - why is this only "(for a different fault)"?

more specifically:

- if there is more than one IMA that caused the fault to be thrown, and there is still at least one open (but less than before) at the end of the <catch missingReply>, what happens? - if the <catch missingReply> opens a new IMA that it doesn't close before it's done, what happens?

the inconsistent nature of dealing with these, especially since they can exitOnStandardFault, truly troubles me.

Two additional changes to the 221 resolution (friendly amendments):

(A) First sentence: Drop "during termination of a scope, " (B) Appendix A (missingReply standard fault):

Result:

(A) Add to the end of 14.4:

-------- The standard fault bpws:missingReply can also be detected if one or more receive operations using a partner link or message exchange defined in the scope remain open. (1) If the contained activity and the event handlers of the scope have completed then a check for missing replies MUST be made. If one is detected then a bpws:missingReply is thrown. The scope itself can catch it as this is still inside of the scope. (2) If a fault handler (for a different fault) has completed then a check for missing replies MUST be made. If one is detected then a bpws:missingReply is thrown to the parent scope (similar to throwing or rethrowing other faults from a fault handler). (3) If a fault handler itself throws or rethrows a different fault to the parent scope then no check for missing replies is made, so a bpws:missingReply is potentially lost (similar to a case where multiple faults have been detected and only one gets propagated). (4) If the termination handler is executed then no check for missing replies is made, so a bpws:missingReply is potentially lost (like any other fault thrown in the termination handler).

--------

(B) Change Appendix A (missingReply standard fault) from:

-------- Thrown when a receive has been executed, and the process instance reaches the end of its execution without a corresponding reply having been executed.

-------- To:

-------- Thrown when a receive has been executed, and the process instance or a scope reaches the end of its execution without a corresponding reply having been executed.

Subject [wsbpel] Issue - 221 - Proposal vor Vote

The last paragraph of section 14.4. "Web Service Operations" (starting with "The fourth extension ...") introduces the standard fault "bpws:missingReply".

Add the following text to the end of the paragraph:

-------- The standard fault bpws:missingReply can also be detected during termination of a scope, if one or more receive operations using a partner link or message exchange defined in the scope remain open. (1) If the contained activity and the event handlers of the scope have completed then a check for missing replies MUST be made. If one is detected then a bpws:missingReply is thrown. The scope itself can catch it as this is still inside of the scope. (2) If a fault handler (for a different fault) has completed then a check for missing replies MUST be made. If one is detected then a bpws:missingReply is thrown to the parent scope (similar to throwing or rethrowing other faults from a fault handler). (3) If a fault handler itself throws or rethrows a different fault to the parent scope then no check for missing replies is made, so a bpws:missingReply is potentially lost (similar to a case where multiple faults have been detected and only one gets propagated). (4) If the termination handler is executed then no check for missing replies is made, so a bpws:missingReply is potentially lost (like any other fault thrown in the termination handler).
