Sorry that's not what I want, my goal is this:
I have several link-call nodes chained together and if one of the fails, then the single catch node should capture it. The variation you posted would continue down the flow if an exception happened inside the link-call node.
That works fine if you only have one link-call node 
Hence me wondering whether the link-call node could throw/raise/trigger the error of the flow it called if there is an msg object returned that contains an error attribute.
