In Composer, I added a state to a workflow, and switched the target state of a transition to the new state; however, after deployment from Composer to the test environment, items in the UI are still transitioned to the former target state. I had originally duplicated the state from an existing state, but on account of the UI behavior I just described, I deleted the new state and created a replacement from scratch; that didn't change the behavior.
There is no Action defined in the new state. In the transition, I added an action to create a sub-task, and deployment was successful for that.
I duplicated an existing transition to connect the new target state to the former target state. I would as soon not replace the duplicated transition from scratch, because it contains many field overrides, but I can if I must.
I no longer have Micro Focus Support for SBM; only for PVCS, but I'm hoping the Community can still be a resource for me for this unusual event.
