[jbpm-issues] [JBoss JIRA] Commented: (JBPM-479) Option to allow Tokens with activechildren not to continue transition

Option to allow Tokens with activechildren not to continue transition --------------------------------------------------------------------- Key: JBPM-479 URL: http://jira.jboss.com/jira/browse/JBPM-479 Project: JBoss jBPM Issue Type: Feature Request Components: Core Engine Affects Versions: jBPM 3.1 alpha 1 Environment: any Reporter: Elmo Assigned To: Tom Baeyens Priority: Optional When a process instance (root token) is signalled in a fork, or in a subprocess, the process continues via the default leaving node. This is quite misleading. In my opinion the desired behavior would be blocking (i.e. means all child tokens must have ended) before continuing the transition. Although this can be managed through code, signalling the token (fork) by accident would give undesired results. If possible, I would like an option to stop the token from continuing if there are still active children. The code below illustrates this: source: Token public void signal() { //initial checking //proposed code: if option is used by developer, block the signal if there are active children if( (CHECK_ACTIVECHILDREN_OPTION) && (this.hasActiveChildren()) ) throw new IllegalStateException( "Cannot signal " + this + " if there are active children" ); //signal routine } This option is false by default. I leave it to the group how they will set the option, either through the node definition (private) or to the process definition or maybe even through system properties (global). The users who will implement this must be aware of the consequences i.e. it is their responsibility to end the child tokens themselves or else it can never continue. This is only an option. I have not fully tested or did a full test case on the side effects of this, so I would appreciate if somebody could point this out because I have it implemented in my code. Thanks. Regards, Elmo
