It is not possible to create (or edit) START OBJECT in Pre- or Postcondition.
How do check if the system is affected by this bug:
A Workflow with any executable object in it is created:
A Pre- or Postcondition START OBJECT is added and all fields are filled in:
No try to click OK:
The dialog is not closed but <PARAMETERS> is marked red as an error. The error does not disappear anymore, no matter what is done:
The dialog can only be closed by clicking Cancel and so the postcondition START OBJECT cannot be saved.
If a Pre- or Postcondition exists from an older Version, it cannot be edited.
They can be opened:
But as soon as OK is clicked, <PARAMETERS> is marked red as an error again:
It affects only START ACTION, not the other actions available for Pre- or Postcondition.
