New process instance in some Activity

[marcosdutto]

Is there anyway to start a process in a particular Activiti, and not in the start Node?

For example I have this definition:

Start -> UTask1 -> UTask2 -> End

And i want to start the instance in the UTask2.

I tried with

ProcessDefinitionEntity pd = (ProcessDefinitionEntity) ((RepositoryServiceImpl)repositoryService).getDeployedProcessDefinition(pdId);
ExecutionEntity pi3 = pd.createProcessInstance(null, ActivitiUTask2);‍‍

but i received

Exception in thread "main" java.lang.NullPointerException
   at org.activiti.engine.impl.persistence.entity.ExecutionEntity.insert(ExecutionEntity.java:1032)
   at org.activiti.engine.impl.persistence.entity.ProcessDefinitionEntity.newProcessInstance(ProcessDefinitionEntity.java:146)

   at org.activiti.engine.impl.persistence.entity.ProcessDefinitionEntity.createProcessInstance(ProcessDefinitionEntity.java:76)

Thanks in advance.

Sure, just put an exclusive gateway in front of the UTask1, with one outgoing flow to UTask2 and start te process  by passing a param tat you check in te gateway…

Starting a process should be done using the API, not by using the ProcessDefinitionEntity directly, this is activiti-internal stuff… Maybe a call-activity is what you are looking for?
