Greetings,

Novice workflow script writer here.  I am attempting to create a workflow that will send product care instructions based on items customers have purchased.  My methodology is:
1. Create a saved search based on sales orders that contain the specific items. (no problem)
2. The saved search looks at the workflow history "state" to make sure the email hasn't already been sent (PROBLEM).

It appears that if the workflow history state is null that I can't evaluate against it.

Example:  Let's call the workflow state "goober".  If I set the criteria to "workflow history:state is not goober" it doesn't return anything.  None of the Sales orders have a workflow history of goober...in fact they don't have anything....so it must be having issues with null?????
