Possible to share record in separate entity?

Oct 10, 2011 at 9:22 PM

I'm trying to set up a workflow to share an account record based on the two user look-up fields in a different custom entity. How I have this set up is as follows:
First, I set up a regular workflow that checks if the two fields have changed. If so, it kicks off a child workflow which consists of using your plug in to share to the users in those fields.

When I test it out, it says it is successful but when I go to the account to check the sharing, there are no users in it.  Is this just not supported or am I doing something wrong?

Thanks,
Dave
