I found the problem, there shouldn't be any whitespaces in process name (the one accessible through edit-> rename) and there shouldn't be "_" underscore character in ID property. When I fixed that my processes started to appear in CalledBy field.
Can you please explain the difference with this three type of names of a process:
1. Name we change in edit -> rename
2. Property Name in Properties
3. Property ID in Properties (format is packageName.anyProcessName) ?
Thanks.
