Hi,

why is there not the same functionality for transient variables as for persistent ones when copying variables from a superprocess to a subprocess (process state)?

I have seen this thread

http://www.jboss.com/index.html?module=bb&op=viewtopic&t=70407

The proposed solution as seen in jira

http://jira.jboss.com/jira/browse/JBPM-399

is implemented in jbpm 3.1.2 that I am actually using.
I think this solution is simple (and buggy: it only works when you also habe some persistent
varibale mappings!) but does not fit for the most common case, that a superprocess calls
a common suprocess and the subprocess does not know anything about the superprocess.

More specific, there could be different superprocesses with different transient variable names.
These superprocesses may call a general subprocess...
Using the present solution forces the subprocess to know about all possible variablenames of
all possible superprocesses - that's really bad! What we need is varible scoping.

What can we do?

Is it is not difficult to implement similar code for transient variables as you did for persistent ones.

Patch for 3.1.3 and 3.1.4 following...
