Just noticed something about the switch node and I'm not sure that it is quite right. Or at least not quite as expected from the help.
```json
[{"id":"100238f1.3386f7","type":"inject","z":"fa3e1078.ef619","name":"","topic":"","payload":"","payloadType":"date","repeat":"60","crontab":"","once":true,"onceDelay":"1","x":150,"y":60,"wires":[["a6eea325.3ec1b"]]},{"id":"a6eea325.3ec1b","type":"switch","z":"fa3e1078.ef619","name":"","property":"fred","propertyType":"msg","rules":[{"t":"eq","v":"naff","vt":"str"},{"t":"null"},{"t":"else"}],"checkall":"true","repair":false,"outputs":3,"x":290,"y":60,"wires":[["b3d407bb.ef2c58"],["e76ff861.4c1448"],["5817b2f6.8024bc","8b5bd9d7.f1a218"]]},{"id":"b3d407bb.ef2c58","type":"debug","z":"fa3e1078.ef619","name":"Is present?","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","x":490,"y":40,"wires":[]},{"id":"e76ff861.4c1448","type":"debug","z":"fa3e1078.ef619","name":"Is Null?","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","x":480,"y":80,"wires":[]},{"id":"8b5bd9d7.f1a218","type":"debug","z":"fa3e1078.ef619","name":"Otherwise?","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","x":490,"y":120,"wires":[]}]
```
The above creates a very simple flow with a trigger, switch and 3 outputs.
The switch is testing a non-existing property of msg. The output happens against the "Is Null?" test. I can kind of see why, there is no property to match on and therefore it might be considered null.
However, the help for the switch node states:
> The `is true/false` and `is null` rules perform strict comparisons against those types. They do not convert between types.
But that isn't what is happening is it?
Anyway, my request is - _should there be an "Is Undefined" test separate to the "Is Null" one_?
If not, should the help for the switch node be updated to show that "Is Null" is also triggered if the property being tested doesn't exist.

Doh! 🤦🏽♂️ 😳
When did that appear and how come I'm daft enough not to have spotted it! (Hint: no need to answer the second part).
