Originally posted by: dglavastormHi Everyone - bit of a strange one, but is there any way to make a node error if there is output.
My specific example - I have an X-Ref node buried deep within a graph containing lots of composites - I need some sort of warning if the right join produces any data as that would signify an issue with the source data that needs to be corrected before the graph can continue.
This could code within the X-Ref itself or an additional node.
Cheers,
Dave
