I have a flowable process running which has a call activity. The first task in the call activity (sub process) encountered an error and it is handled using a error catch event and the main process is still running. I need to restart the call activity alone in the running process. Is it possible? In other words, I want to change the state of a process in execution at run time. Is that possible?

Hi,

yes it is.  
Have a look on [ProcessInstanceMigrationCallActivityTest](https://github.com/flowable/flowable-engine/blob/7489d2f52fe637822d9dabd45775452249603802/modules/flowable-engine/src/test/java/org/flowable/engine/test/api/runtime/migration/ProcessInstanceMigrationCallActivityTest.java).

Regards  
Martin
