Hi,
In Java compute node, Iam using condition to out put .
if(outAssembly!=null) {
out.propagate(outAssembly);
}
else {
alt.propagate(assembly);
}
what happens if I donot connect alt terminal ?. is the flow ends at that terminal for alt condition ? |

The same thing that happens if you RETURN TRUE from a Compute node that has nothing connected to it's out terminal.
Or propagate to an out1 terminal in a compute node if you PROPAGATE to that from ESQL.
Or have an MQInput node that has nothing connect to it's out terminal. |

Your message thread drops off a cliff into the deepest darkest back hole you can ever imagine.

The message thread completes processing the current message flow instance and is available to be reallocated to another message flow instance.
That is, the flow instance ends. full stop. successfully. |

Indeed but as far as the user is concerned when you propagate to a unconnected terminal, that is the end. Full stop. Hence my use of the 'black hole' analogy. Then in the background Broker does a whole load of cleanup before the thread can be reused. But all of that should be of no concern to the user.

I did not view "black hole" as "completes successfully".
Perhaps it's just because I'm not British. |

Non-Britishness is an unfortunate condition, but I don't think it can be blamed for this lapse  |
