"jBPM 5 Loop Type support?"

1) Subprocess Loop Type:

According to the jBPM 5 user guide and some jBPM 5 blogs, the "looping back" seems to be supported from the subprocess (and multi instance). However, from the Eclipse BPMN2 Process editor (which came with the jBPM 5 installation), I couldn't find any subprocess property field for the subprocess looping. How do I set the subprocess loop type from the Eclipse BPMN2 Process editor? 

The Oryx-based designer integrated with Guvnor has the subprocess loop type, but this designer does NOT allow me to "save" any process defintion with the subprocess (does NOT support the subprocess enum yet),as I reported earlier.

So, I cannot use either BPMN 2 designer to define the looping subprocess. Does anyone have a suggestion for this? Any help will be appreciated.

2) Process Loop back:

For putting the loop back in a process, one blog suggested using a converging parallel gateway and a diverging gateway as follows:

But, the "Hello Again" acitivity was never executed. It seems to me that the converging parellel gatway <+> is waiting for the "Hello Back" before it goes to the "Hello Again" activity. It is possible my configuration is incorrect. If the process loop back is possible, how do I do it?
