_Hi, I'm not sure where is best to post this._

The `trigger` node set to **send the latest msg object** is not passing the latest msg object, but the first msg object with only the payload value replaced.

Here's what it looks like:

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/9/8/988ccdf00eb197c631f8aa2544751dbaac692690.png)

The `trigger` node settings:

I am expecting the debug `Passed message` to be equal to `Message 2`.  
Instead, it is a mix of `Message 1` and `Message 2` msg-object contents.

The code to reproduce (Node-RED 1.0.3: Maintenance Release):

```auto

```

This looks as a bug to me. Am I wrong?

Hi.

It's nice to see I am not the only one who plays around the limits of the program.

Don't be afraid to ask if you don't understand something.  
It is only when you try these sorts of things do you find problems/bugs/etc.

Sorry, but I'm fairly new to Node-RED and did not figure out yet how it is maintained.

Which repo includes built-in (?) nodes?

ONLY for the sake of curiosity, where on the local machine is the code for the node?

Is it like the other nodes or is it in a bigger package?

I've tried finding it but to no avail.

I didn't know it was actually called `89-trigger`.

Thanks.

Yeah, ok.

But that is _unexplored land_ for me. I'll have a _butcher's hook_ at the code when I get time.

I'm not good with the github repository.

It is surely valuable time spend, if you click the history button for that file, you can see that @dceejay already made [changes to the code](https://github.com/node-red/node-red/commit/1868289b7127e372be9b2eb72e61240e89be2b53)

Please,

I am not trying to _shame_ anyone. I am just curious to see the code with the problem and see if I can _nut it out_ myself.

Though I will update the node to the newer version all the same.

Small hint: while browsing the GitHub repo, you can press t on your keyboard and enter a filename (or a part of) -- it will show you matching files.

What is the meaning of the numbers preceeding the nodes' names?

Is it some kind of prioritization?

Not so much ancient history, rather a key way we are able to control what order the nodes appear in the palette.

Ok. But when I go to the palette manager there is no update to the `trigger` node.

Sorry if I am even dumber than I usually am. There are a few things going on which are really not helping me.
