Execution Query

kayj — Thu, 06 Nov 2014 07:59:13 GMT

Hi,I've got a quite simple example: ProcessEngine processEngine = ProcessEngineConfiguration .createStandaloneInMemProcessEngineConfiguration() .buildProcessEngine();RepositoryService repositoryService = processEngine.getRepositoryService();RuntimeService runtimeService = processEngin

It seems that the process is finished and not waiting. can you send the process ?

Re: Execution Query

jbarrez — Mon, 10 Nov 2014 11:21:13 GMT

There is a whole lot optimization going on to get the amount of executions as small as possible. So don't try to logically see how many you expect, the engine does optimize and recycle quite a few of them.

Re: Execution Query

kayj — Thu, 11 Dec 2014 16:32:40 GMT

Could you explain how to send a signal to a specific execution (e.g. <code>mProcessEngine.getRuntimeService().signalEventReceived("continueSignal", executionId);</code>) if the execution is no more available (as mentioned before)? I did not find a solution to this problem yet.
