This page contains information on:
The publish exception node produces a publication when an exception occurs in a message flow that is attached to the 'out' terminal.
The publish exception node has one input terminal called 'in' and two output teminals called 'out' and 'publish'. The message received on the 'in' terminal is passed directly to the 'out' terminal. If an exception occurs and is received by the Publish Exception node, then a new message (a publication) is created and is propagated to the 'publish' terminal.
The 'out' terminal needs to be wired to the remainder of the message flow, The 'publish' terminal needs to be wired to a Publication node.
