Kind of a crosspost of this thread: http://connect.nintex.com/forums/thread/29646.aspx
It doesn't appear to happen when the workflow itself is simple and small, but once it reaches a certain point, it begins to throw these errors. I can enter a user or email address into the field, but it will not allow me to use any lookup values.
I am running Nintex Workflow 2010 Version 2.3.7.0
Screenshots below:
The box outlined in red is where I'm attempting to add a lookup to a field called 'LegalRequestedTo' (a people picker field) on the list item the workflow will be running on.
I'm able to get the dialog that allows me to select the lookup...
But as soon as I attempt to save that selection by clicking 'OK,' I get an error.
What is happening and can anyone help?
