I have to fill the input widgets with values when I arrive at a
workflow step. I would do it in the onEntry, but at the first onEntry
call the user interface is not ready.

So I have to check in the onEntry if the GUI is created or not. This
cannot be queried by the ctkWorkflowStepWidget functions.

But no problem, I rearrange my code so I can decide it by a null check.

Best,
