Max Rydahl Andersen commented on JBIDE-3088:
--------------------------------------------

A good wizard listens to what is currently selected and performs its initial setup based on it...but of course if the underlying selection is not mappable to something the wizard can handle it should just do its default initialization.

> If the resource (file/folder/project) selected when the BPMN -> jPDL wizard is launched is not a BPMN file, then the wizard does not open, failing with the exception below. Since the user selects the BPMN resource(s) to convert on the first page of the wizard, it should not matter what the current selection is when the wizard starts:
