Conditional unassign issue

Question

Hi guys

On a screen used by a workflow transition I have a custom field 'Clear Assigne'. It is a multi select box with only one option 'Unassign Issue'.

In the transition I now want to unassign the issue if the checkbox is set. I was using the 'Set a field from a set of rules based on regular expressions'

The post function looks like:

The field Assignee will be set according to the evaluation of Clear assignee against the following set of rules: 
(Unassigned)Unassigned

I also tried '' instead of Unassigned for the replace value. But whatever I do the Assignee doesn't get unassigned.

Has anyone an idea how I could do this?

Thanks a lot

I was able to create a transition which cleared the assignee using a different post function.

Now if I use this function allowing me to go through a regex first, the general configurations need to be modified to allow unassigned items - where with the other post function this was not required. Which is unfortunate as this is now making all projects available for unassigned issues. Also everywhere and not only in a specific transition now the assignee can be left blank.
