Inject node only fires if msg.payload defined?
So, msg.payload as any value, inject node fires when clicked. But if msg.\* exists, but no msg.payload exits inject node does not fire. It is kind of a pain to add a change node to delete the payload, when you are just doing UI effects initialize, for example, enable/disable, color changes, etc., and the UI element is in pass-through mode, and should expect a payload other than initial message received for setup.
Another thought, would be nice if inject node could fire on context values as well, by the way. I often find I want to inject flow.\* (something), but have to setup a change node to grab the flow variable because inject can't directly.

No, it works for me. What version of Node-RED?

Why not?
If your inject node doesnt look like this ↑ you are probably on a much older node-red version.

Ah... was this implemented in 1.2.9? But my initial question still stands... inject node firing without msg.payload existing.

Havent ran V1.1.x in over 9 months so cant say.
could be a bug with a specific version you have (you didnt say which version you are running)
Can you not upgrade?

Moving to 1.2.9... just have not gotten all the Pi devices to it. 🙂 Most of my Pi Zeros are 1.0.6.

Don't feel so bad. I'm still running v0.18.4 on about 20 of the pi's in a industrial setting monitoring temps. They have one job and they do it well .... aint going to muck with it 😛

LOL! Yeah, I have about 10, and just for home automation and fun stuff... No real production... But what a PITA it is to update. I even automated the update so it is just a one click process. But I still seems to take forever to do it.

Yes, with the current version you can inject an empty message. It will just contain the msg id.
