Yes, it's true, but no way to resume the activity on "inactive-scope" and then signal the main instance?
My problem is that I *cannot signal the main process*, either if sub-process is "+active-root+" or "+suspended+", etc:


INFO  ProcessServiceBean - SUB_PROCESS STATE: SubProcessRequisitesEvaluation.340002 active-root
0.0.1. EXCEPTION ###########################################
12:00:32,886 INF | DefaultCommandService exception while executing command org.jbpm.pvm.internal.cmd.SignalCmd at 34e1d5
org.jbpm.api.JbpmException: execution[MainProcess.50026] has running subprocess: execution[SubProcessRequisitesEvaluation.340002] in state active-root




So "root execution" cannot be changed whatever state  are their relative "sub-executions"!

You talk about a "wait state", but my suspension is acting like a wait state, and i have provided a timer to fire after a timeout, to "resume" process-execution, the problem is *to move* the whole workflow instance to that state.
For now I cannot achieve this if sub-process is running, and the solution cannot be to force ending because the sub-process will be locked anyway.

I have completely freedom for implemention  but my stand points are:

1. use sub-processes & choose the definition in runtime;
2. enforce the suspension in the root-process;
