Hi,
Looks like that some javascript libraries are checking on the argument length of the callbacks that are passed to them.
So for example D3 bisector can take a function with one or two arguments. If it is one then it is an accessor if it is two then it is a comparator.
I searched on github issues. Should I report it?
The following snippet demonstrates the problem. The Function.length should be 1 and not 0.
@JsFunction public static interface SomeFunction { public double call(double x); }
/** * This is the entry point method. */ @Override public void onModuleLoad() { final SomeFunction y = new SomeFunction() { @Override public double call(double x) { return 2 * x; } }; DomGlobal.console.log(y); return; }
