Join Node Confusion

General
1

I am trying to combine the payload of a number of different nodes into a single payload.
I am able to get 2 payloads to combine in the proper order but when I add a 3rd or more nodes the order is scrambled.

I did notice in the debug window that each node had "string[##]" attached. I thought that the order was based on the bracketed number but that is not the case.

I can't decipher what is controlling the order.

This is my flow:

I'd appreciate any help/advice

I can't look at your flow at the moment, but if you are not doing so then look at the key/value pair mode using the topic as the key. Then make sure the individual messages have different topics.

@Colin
Ah, I keep forgetting that I can change the mag.payload to something else.
So now I have an object with 5 parts in the correct order.

object
1: "Good Morning. Here is the weather for "
2: "Today. Mainly cloudy. High plus 2. UV index 1 or low."
3: "It will take approximately "
4: "15"
5: "minutes to get to work this morning."

I don't even know what I have now to look up how I change it to JSON :slight_smile:
