Re: OSWF Parallel steps

That's it, thanks a lot for your explanation, it is a very interesting
approach.

Anibal,

I'm not sure i understand your question, but I will give you the
workflow I would use for james case.


"General" workflow:

    Step 0. Initialize Workflow
        Action 0. Initialize -> Go to Step 1 / docNumber = 0;

    Step 1. Initialize review board
        Action 1. Add reviewers list -> goto Step 2 /
                         instanciate one sub-workflow per reviewer,
                         store the wfids in a variable.

    Step 2. Reviewing Document
        Action 3. Review Document [if all sub-wf in step2] -> goto Step3
                                  [else] -> goto Step2

    Step 3. Review Finished


"sub workflow":

    Step 0. Initialize Workflow
        Action 0. Initialize -> Go to Step 1 / store parent wfid

    Step 1. Waiting for vote
        Action 1. Accept Document  -> Go to Step 2 / doAction 3 on wfid
        Action 2. Reject Document  -> Go to Step 2 / doAction 3 on wfid

    Step 2. sub-review finished



Is it the answer you expected?
