Ok I found a way using the Design mode. When on my Decision Node, I can right click on it. I then select in the menu Add Child and then Handler. i can then do on the added handler a Add Attribute -> class. Then I can type my class. Ronald, if you were talking about the Diagram mode : The only proprerties available to me just allow me to enter a new name to my Decision Node. I don't understand what you call "Select open the properties tab" neither "select your decision handler". View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4086766#...
