Sharepoint StateMachine : Handling multiple responses to multiple created tasks

Question

Hi,

I created a StateMachine workflow for sharepoint and at one state, I create multiple tasks using a replicator. The number of tasks created is variable.

I need to handle the OnTaskChanged event for all the tasks I created which seems impossible as one event handler can only be associated with one task.

I can use a restrictive number of tasks which can be created and handled by a specific number of handlers but I am considering that as a last resort or create a sequential workflow as a last resort.

Please do let me know if this is even supported or if there are any workarounds.

It won't work for the reasons you laid out. The workaround is to restructure your state machine workflow as a sequential workflow (which may not be possible) or to switch to item event receivers (which may not work for you). I've actually blogged about this topic: Workflow Nuttiness vol. 1

Hilariously, I just checked the MSDN forums link you provided, and sure enough, I'm in that thread, asking "so, uh, I guess we all rewrite to sequential workflows?" And there's no better answer in that thread either :)
