[FLOW3-general] Object argument becomes null

[Scott MacDonald]

Thanks for the help, guys. Unfortunately, it doesn't work. Here's what 
happened when I tried various things:

Actually, it seems to generate a UUID just fine (from tracing it via the 
debugger), but the UUID winds up referring to nothing in the end.

Calling $this->editAction() technically works, though now it is looking 
for a template attached to the create action. I could use this as a 
workaround, but since in the end there will be two create actions 
leading to a common edit screen, it seems like it would be cleaner to 
have the edit action call the appropriate view.

Changing redirect() to forward() made no difference: $disc is still NULL 
when it gets to the edit action.

To use the PersistenceManager, I injected one into the controller and 
placed a call to $this->persistenceManager->persistAll(); right before 
the redirect. All I got was a blank screen with the URI showing that it 
hadn't moved past the create action, so I ran the debugger and found 
that it stopped executing after the call to persistAll(). (I assume that 
the blank screen at that point is because there is no template set to 
display for that action; please correct me if I'm wrong.) Did I make the 
call wrong?

Thanks again,

Scott
