thanx for ur quick reply. The second option (multiplicity attribute) may not work for me :( coz, number of transitions may vary as per my requirment.(0 to 7 and more) Option 1 -> suits better for me. I've changed the JoinActivity of JBPM Source code and its working. But it should not be like this :) I want to create my own custom join, but i don't know how to bind this Join :( Any suggestions ??
