I have tried both 14.1 and 17.1 and I am unable to add a transition condition to classic wf statuses (any). I saw it uses the same form so I am confused how that would be available for the basic CHG wf but not cr_wf. What am I missing? It is the base form (no mods) (see screen capture of cr_wf Transition Information in Edit mode, the Message is fine but the Condition field does not show).
