I'm experiencing odd/eratic behavior from Nintex Workflow 2013. Several things are happening.
Most of the time, when attempting to Save or Publish, or work with variables, my buttons remained grayed out (not selectable).
Or, when creating a Creating a List Item, it does not recognize a workflow data choice as a valid option to populate a required field. When I save the step it displays the exclamation point warning, and I'm not able to Publish the workflow in this state. I find myself changing the choice to a contrived Value, just to get it to save and then after I Publish the workflow I'm able to change the required field choice with a Workflow variable. Sometimes even that doesn't work.
Is anyone else experiencing this behavior - has anyone found a fix?
