Description
I have these basic bindings to reactjs and I'm getting a type error from which I can't figure out why its happening/where to look.
To reproduce, first need:
https://github.com/fxfactorial/runa, which you can pin opam pin add runa
(note the branch new_ideas)
and then https://github.com/fxfactorial/ocaml-reactjs/tree/new_ideas, and make debug should build the project, it assumes OS X but you can just open the index.html in example/tutorial/index.html.
This creates a button and clicking the button, things seems to work, the state is changed correctly, but then this type error comes up and I can't catch it with try/with
The problem gives this stack trace
stdlib.js:60 Uncaught TypeError: Cannot read property 'fun' of undefinedcaml_call_gen_U_ @

So something in react is calling my code.
and it blows up in stdlib.js on:
function caml_call_gen(f, args) {
// I want to put a debugger statement here
if(f.fun)
return caml_call_gen(f.fun, args);
var n = f.length;
var argsLen = args.length;
....
and as the comment mentions, I'm trying to put a debugger statement in there. I thought that putting the debugger in the ~/.opam/<the_switch>/lib/js_of_ocaml would work since it would link against the standard lib there, and I seemingly see it changed, with the debugger statement, in chrome dev tools for the file stdlib.js, but I don't get the breakpoint going on.
How can I debug this?
