Duplicate sub-tasks are getting created

Kalpana Ramesh

While creating launch task, duplicate task got created. While trying to create the issue, an error message is popping but gets created anyway but as duplicates.

The error message is as follows:

Error creating issue: Cant transition workflow instance#319029. Current state is 0, requested state is 1.

How can this be rectified?

Thanks!

That suggests you have a (broken) post-function or listener creating extra issues.  Start with a look at the workflow - what post functions does the "create" transition have?
