Hello Koen and jBPM community OK, so I answered my own question about the delegation actionHandler Config-type Field and getting it to prompt for field values in the designer action properties dialog. The solution was (after adding an appropriate instance variable into the particular actionHandler in question) to go into the Properties dialog for the action and to place the cursor after the name of the actionHandler class and to press "enter" on the keyboard. This then (evidently) causes the designer to re-evaluate the actionHandler class for any code changes and then it recognizes the presence of a new instance variable.
