I think that you can ignore these questions for now, as I was foolishly working on the "v16" document from GridForge, rather than the "v13" document circulated by Andrew G. on the list, which seems to be a later version despite the lower version number.

Also: I am looking at the definition of the "Suspended" state. I understand that one way to get there is for a client to request a transition to that state, either by an initial CreateInSuspendedState flag or by a RequestActivityStateChanges operation. Is there another way for this state to be reached? The document includes these words:
"If any staging action enters the Suspendedstate, then the whole activity enters the Suspendedstate."
That implies to me that there is some way for a staging action to enter the Suspended state independently of the activity as a whole. How does that happen?
Thanks -- Ian.

Hi,
I am reviewing (and editing) the BES document, and have a question that doesn't seem worth raising in a tracker.
In the state discussion, there are sentences something like the following:
a) An activity stays in the StagingOutstate until all staging out actions have moved to a Terminalstate (Done, Exception, Terminated).
b) If the terminal state of any staging out actions is Exceptionthen the activity moves to a Exceptionstate.
I interpret these two sentences to mean that we only enter the Exception state when all staging out actions have completed. I.e., that if one stage out fails, but others are still going, we wait until the others have completed before moving to the Exception state. Is that correct?
Thanks -- Ian.
