I have no idea...
What are you trying to achieve
I want to set custom properties in jpdl for transitions, so I can use them when deploying the process.
I do not see that method on Transition in jBPM 4.3/trunk, so I guess is either removed.
Besides that, I do not suspect it would have been for the use case you want it to be. What do you want to use if for deploy time?
I just want to use self custom attributes in jPDL.
<transition name="to_end" to="end" showform="/showEndTask.xhtml" />
Can I get it easily?
