When you use the CallActivityBehavior class as a foundation, then it will do exactly what the current call activity does for you, so yes the parent process will wait until the child process is completed.</SPAN><BR /><BR /><SPAN>Best regards,</SPAN></BODY></HTML> Thu, 24 Dec 2015 08:02:33 GMT https://connect.hyland.com/t5/alfresco-archive/programmatically-calling-a-callactivity-in-java/m-p/225658#M178788 trademak 2015-12-24T08:02:33Z
