I see that the MQTT Out node correctly generates an event that can be caught by a Complete node when it has sent the message to the broker, but it does not appear to generate an error that the Catch node can catch if I send a message while the broker is disconnected. Is this a bug or just a feature that has not been implemented? If it is a missing feature are there technical issues that make it difficult or impossible to implement?
I think that you can catch if the broker isn't connected can't you? That would be more robust anyway.
The status changes, but I haven't been able to work out how to know that a particular message has not got through. A Catch node doesn't catch anything.
This is in contrast to the email out node. When you pass it an message to send it always either signals a Complete or a Catch event.
