I have created parallel action which contains 5 branches of parallel action using Nintex 2007 and SP 2007. Each branch starts a new workflow. After executing all "Start Workflow" action , it is giving error and no error displays in workflow history. Please find below screen shot and appreciate your suggestion.
I would suggest to put pause right before the "Start Workflow action item". Like pause for 2 min's for first start workflow action and pause for 4 min's before start second workflow action item.
I would ask why are you kicking off 4 workflows with one? That's bad juju waiting to happen. While its possible, you could achieve something similar with a slightly different approach.
Can you share more on what you are really trying to fix or do with this workflow?
I would disable all of the parallel actions except the first one to see if an error occurs there. If so, I would try to do some logging history of some of the workflow variables. If no errors appear in the first branch, I'd enable the second and so on until you find which branch is causing the error. For us, we can't really troubleshoot this since we don't have details (error logs, variable values, etc.) behind the scenes. All we can do is give hints on troubleshooting.
Interesting, I am seeing something similar today but for an on-prem version of 2013. There is a parallel action with 3 branches, two of which start a workflow, both displaying in yellow and halting with nothing progressing further. I'll report back if I can come up with anything.
