Hi Jon,
This explanation doesn't quite make sense to me, since we have both assignee and resolution code as dependent attributes for the resolved and closed statuses, and we are able to complete those fields and change the status using edit in list in one step.
However, we've seen some other quirky things happening with edit in list. For example, sometimes (not always) when the assignee field has previously been completed and saved and we try to change the status to resolved or closed, we are seeing that same error on the assignee field.
Also quirky is that for some fields that we've added to the edit in list functionality, we aren't able to edit them and get the below error on that field. We submitted a ticket last August for this (00470872 - Edit in List error message) and was just recently told it was fixed and will be included in the next cumulative patch for 14.1, which is scheduled to be available early this summer.
