re-frame reloading

jstaffans what do I have to do to make the re-frame simple example preserve state when figwheel reloads? ie the content of the input gets reset to the default value when figwheel reloads currently. https://github.com/Day8/re-frame/tree/master/examples/simple)

[6:30 PM]  
pesterhazy @jstaffans that should work actually

[6:32 PM]  
what I'd do is to start debugging where reloading goes off the rails

[6:32 PM]  
I'd start by adding logging to the render functions, printing out global state

[6:32 PM]  
isolate if global state gets updated incorrectly

[6:33 PM]  
the simple example seems a bit too simple also in that it doesn't re-render the root component (there's no on-js-reload fn as far as I can see)

[6:34 PM]  
it might be worth copy'n pasting the example into tenzing (or chestnut if you prefer lein?)

[6:35 PM]  
I suspect the issue is not to do with re-frame but with reagent or tooling by the way

[6:41 PM]  
jstaffans Thanks @pesterhazy, I'll try that out

[6:42 PM]  
I was expecting something like an on-js-reload function being needed

[6:50 PM]  
pesterhazy a couple of other reloading gotchas:

- using clojure.core/atom instead of reagent.core/atom
- forgetting to use `#'component` to enable reloading
- top-level root component sometimes don't get updated properly; wrap in another component to be sure
- "rookie mistake"? https://github.com/Day8/re-frame/wiki/Creating-Reagent-Components#form-1-a-simple-function
- input fields: `default-value` vs `value`
- logic check: does the component to update deref the ratom?
- defmethod based components can be wonky in reagent
- on-js-reload should re-mount root component
