How to signal state without giving transition name?

I am using jbpm4.3. I have state say "state0" from state0. I'm signalling another three state say "state1", "state2", "state3" without using fork.

But I forgot to give transition name to each state. Now I have complete jbpm database without transition name in .jpdl.xml. When I'm going to signal the activity state0 to state1, it is not signalling because of it is confused where to signal. I got three another states with the same execution. Now I have to 开发者_开发技巧give the transition name for proper signalling, but I do not have to change my jbpm database.

So, what I have to do?
