could somebody paste a script example for fork

[luowp]

I just want to add a piece of script to customerize my fork. It need get value from a process varible a. If a==true, the fork goes to three transitions, otherwise, just goes to two transitions. I am trying to using expression in transition.



a


it throws exceptions.

Has anybody a small piece of example script? Thanks in advance!

You probably need a decision node with conditional transitions.

<decision name="forkTest">
<transition name="to_three_fork">
<condition expression="#{contextInstance.variables['a'] == true}"/>
</transition>
<transition name="to_two_fork">
<condition expression="#{contextInstance.variables['a'] == false}"/>
</transition>
</decision
