Creating an implicit loop - retry a failed step

[Paul.Bakker@osr.treasury.qld.gov.au]

WF'ers,

Hi, here's my dumb question for the morning.

I am trying to set up a very simple workflow that has the following
(partial) logic:

1. Change document (background step)
      2. If 'Change Document' failed, ask user if they want to retry (user
decision)
                  3. If the user chose 'Retry', go back to step 1
            4. If the user chose 'Exit', finish the workflow
      5. If 'Change Document' succeeded, finish the workflow

Simple, no? But when setting it up in the graphical editor,
I cannot work out how to make step 3's 'retry' outcome point back
to step 1. I thought you could just grab & drag the arrow, but it
refuses to budge.

Is it even possible to set up a workflow this way, or do you have
to make an explicit loop? That is more work (adding an UNTIL
loop, new workflow container element, container operation steps etc..)
and it 'clutters' the workflow. I'd rather have an implicit loop.

Any tips?

thanks,
Paul
