Accessing Flow id or name from DelegateExecution

plehal — Thu, 01 Mar 2012 00:51:48 GMT

How do I get Flow id or name from DelegateExecution object if I am listening on a flow/transition? There does not seem to be any method inside the listener which provides access to these attributes either directly or indirectly through access to RuntimeService etc.I know I can add fields to the flow

Hi,

I think, the execution passed into your notify() method implements DelegateExecution and this interfaces defines the methods you need.

The DelegateExecution does not seem to have any method which provides access to flow name etc. If you know some trick to do it, please, provide some details.

String processDefinitionName = repositoryService.createProcessDefinitionQuery().processDefinitionId(runtimeService.createProcessInstanceQuery().processInstanceId(execution.getProcessInstanceId).getProcessDefinitionId()).getName();

How do you get repositoryService or any service for that matter from DelegateExecution because at that time only object that is passed to the method is DelegateExecution?

This should help: http://www.activiti.org/userguide/index.html#apiEngine

ProcessEngines.getDefaultProcessEngine() will initialize and build a process engine the first time it is called and afterwards always return the same process engine.
