Following on from my other question about updating NR from 3.0.2 to 3.1.5....

I made a lump of code in a `function` node on the 3.1.5 machine.

In the `on start` tab I have:

```auto
// Code added here will be run once
// whenever the node is started.
context.set("counter", 0)
context.set("rounter_status", "unknown")
context.set("pip_status", "unknown")
context.set("modem_status", "unknown")
context.set("internet_status", "unknown")
node.status({ text: "RESET" })

```

And if I modify the code/node when I `DEPLOY` it says `RESET`.

I export it to a machine with 3.0.2 and that doesn't happen.

Is it a version problem or something else?

(off topic: I just saw the typo in the code I posted. But still... It doesn't seem to be done on the second machine. Right or wrong code.)

The status will only be set once the function has received a msg. use debug nodes to confirm a msg was sent to the function.

I think there is confusion with what/how I explained things.

(and now I'm trying to capture it: it is not playing the game.)

Ok, I'll have to fall on my sword again.

Sorry.

I maybe cried _Wolf_.

Here is an example of what I see happening WRT the `on start` tab.

A message was received and the `status` changed.

I edited some of the code in the node.  
I press DEPLOY

Now you see that it is doing the `on start` code.  
Which it didn't seem to be happening before when I asked.

The code - again for clarity:

```auto
// Code added here will be run once
// whenever the node is started.
context.set("counter", 0)
context.set("router_status", "unknown")
context.set("pip_status", "unknown")
context.set("modem_status", "unknown")
context.set("internet_status", "unknown")
node.status({ text: "RESET" })

```

Most importantly the last line.

There are no other messages arriving.  
This is a controlled environment.
