I've been developing some workflows on a dev machine with Nintex version 3.0.5.0 and everything works fine.
When I export those workflows and then import them into a staging machine which has Nintex version 3.0.6.0 my workflows fail with an error ("An error has occurred in XXXX Workflow.") whenever they get to a Task action. I found that when I configured the Task, near the bottom, on the staging machine there is always a Due Date field displayed. This Due Date field is not displayed on my dev machine unless I specifically select it from the Field drop down related to the Content Type.
On the staging machine if I configure each task and set a Due Date the workflow functions properly and the tasks are created. But we don't want our tasks to have due dates assigned to them.
I've checked the Workflow Tasks lists and Due Date is not required for any of the content types.
Has anyone else encountered this? Is this a bug?
