Problem/Motivation

I added the workflow to an existing content type with content created for it. Now it's impossible to save the node because there is no state transition from an empty value to a state.

Steps to reproduce

  1. Create a content type and add some content.
  2. Create a new workflow with some states
  3. Add a new workflow field to the content type
  4. Edit an existing node and try to select a state and save
  5. You will get an error like "No transition exists to move from [EMPTY] to [STATE]."

Proposed resolution

The easiest way would be to update the constraint to skip empty field values.
