Jakub Havl=C3=ADk commented on FALCON-1565:
--------------------------------------

I would like to point out that this error also happens when you try to list=
 instances of a process which is not yet started (same code, different call=
 path).

Process definition:
{code:xml}

Calling process status command before validity start results in the same er=
ror:

This is not expected behavior. Expected behavior is receiving info message =
saying that there is no instance because we current time is not after start=
 and before end of validity of this process.
