Unable to Dispatch Requisition using ReqEntry Adapter

Hi Guys!
I am trying to do the same thing. I have a dashboard with a UBAQ and BPM inside. If the user click a part number from my dashboard, and click the button, then a req is automatically created. The req detail line is created, and then I try to dispatch it, but nothing happens. I am not trying to use custom code widgets, just the BOs and methods.
Part of my approach: UBAQ to Create Requisition

Did anyone resolve this?
