Modifying alfresco advanced workflows on the fly

[kamlesh]

I would like to modify an instance of a workflow (not the workflow definition) on the fly by adding/removing task nodes by providing some kind of user interface to user.
Ex if there is a workflow definition with nodes A-> B-> C-> D and there are 10 instances running is it possible to change one of these instances a-> b-> c-> d by adding a new task node like a-> b-> b1-> c-> c1-> d.
Let me know if this is supported by Alfresco workflow APIs.

I am pretty sure this cannot be achieved via any API.
Any workflow instance that was started will keep its definition until it is completed.

Thanks for the quick reply!

Is there any other workaround for achieving the same?

JayJayECL is correct that you can't change a workflow on the fly.

However what you would need to do for your use-case is to anticipate and build in the decisions into your workflow.   

Two approaches that will work for your example.
    you could always include "b1" but make it a no-op depending on a condition.
    you could have a decision node in your workflow,   "how many instances running > 10 B1 else C."
