BPMN: current execution id, process instance id

capacia — Wed, 27 Apr 2011 12:44:43 GMT

Is it possible to get the id of the current execution and/or of the current process instance within BPMN?

I do not have a real clue what you mean. If you are in a process instance, you have already access to it… Or do you mean as an expression in e.g. a java task somewhere?

Yes as an expression. I want to call a service using a service task and one of the parameter shall be the process instance id and/or execution id.
For example:


…
<scriptTask id="scripttask1" name="Prepare Params" scriptFormat="groovy">
<script><![CDATA[
    piid = [processInstanceId];
    eid = [executionId];
]]></script>
</scriptTask>
…
<serviceTask id="servicetask" name="" activiti:expression="#{myService.doSomething(piid, eid)}"></serviceTask>
…

In expressions (http://activiti.org/userguide/index.html#apiExpressions), you can use:


<serviceTask id="servicetask" name="" activiti:expression="#{myService.doSomething(execution.id, execution.processInstanceId)}"></serviceTask>

In script-tasks, unfortunately, the execution (DelegateExecution) is not yet exposed (only the variables). Can you create a JIRA improvement for this?
