Why startprocessbyid does not support version?

[yuanqixun]

I see the javadoc,I can't see the API has any version param, should we start process of latest version every time? I think this is not alway true,right?

org.activiti.engine.RuntimeService#startProcessInstanceById(String processDefinitionId)

The processDefinitionId String consists of the process definition id as well as its version number (plus some random number).

One way to get that processDefinitionId String is to call org.activiti.engine.impl.RepositoryServiceImpl#createProcessDefinitionQuery

Thank you Etienne, I'm wrong.
I just think the processDefinitionId is the process's id. Here, we use process key to find the process,right?

[etienne]

Yes, you query for the ProcessDefinition entity, from which you can then take the id and use it to start the process.

The process definition id is uniquely pointing to one process definition.
Hence it makes no sense to specify a version, as it does when specifying a key.
