Steps to Reproduce:
In the Create transition for a workflow add a post function that updates an issue field. To reproduce the problem it must be after the *Creates the issue originally. * post function.

Potential Use Case:
A common usage of this post function is to set the assignee to some value other than the project lead/component lead etc.

Expected Behaviour:
The field is updated as specified by the post function.

Actual Behaviour:
The field is not updated.

JIRA 3.10.2 Workaround:
Make sure that the update issue field post function occurs before the *Creates the issue originally. * post function. Note that this workaround does not work with the Resolution field.
