Is "Create an actor filter page" sample code is correct?

I was following the "Create an actor filter" documentation and there is a sample code implementation, When I look at the javadoc, I cannot find the  getParentProcessInstanceId() from EngineExecutionContext. Is this renamed to getRootProcessInstanceId()? 

Thank you

Hello,

Let's imagine you have a process "Europe"

in this process, you have a call activity to the process "France"

And then, in the process France, a call activity to the process "Grenoble". 

In a task in the process Grenoble:

* the getProcessInstanceId() return the processID in the process Grenoble

* the ParentProcessInstanceId() is the processinstanceID in the process France

* the RootProcessInstanceId() is the processinstanceID in the process Europe (this is the case ID the user see)

You can use LongBoard (https://community.bonitasoft.com/project/custom-page-longboard) to understand and see the different processnstanceid

If you need to access the ParentProcessid, then you have to use the ProcessAPI (hum, saying that, I don't see the way to access the Parent in ProcessAPI - search or a containerId)

Hope this help,
