[USRP-users] does an RFNoC block HAVE to have an input and an output?

I have a block that I want to essentially be a source block in RFNoC 
(outputting data from a ROM), but when I go to probe, I get this error:
RuntimeError: LookupError: Path not found in tree: 

Is this because I set it up without sink input?  Is there any way around 
it?  I think the solution is to put a sink in the rfnoc/blocks/ XML file 
but NOT the grc XML file, is that right?
