Model Builder ADD FIELD problems

I am having some problems that can be illustrated with the very simple model attached. 
This model works fine (using %Workspace%\output as the output value).  But as soon as I include an 'Add Field' tool using the 'output' as input table nothing works.   The model runs and says that it is successful, but there is no data in the output workspace.
Thanks for your help,
