Ronald van Kuijk commented on GPD-201:
--------------------------------------

just so that everybody knows

There is a space behind the transition name in selected by the expression. Not sure if this was a slip of the keyboard or something the GPD did. Trimming the expression in the GPD would make it more explicit that this will not happen. Trimming it in the EL handler would to, but that is a separate issue

> I have defined a process definition with the following decision node where Account is a POJO. I can see that the Account as a jBPM variable in the jBPM Admin Console.

> 		<transition to="Replenish Account" name="false"></transition>
> </decision>
> When I execute the process, I get the following errors:
