Hello,
I'm working on updating/migrating the gwtbootstrap3 library
- updating all external Javascript libraries
- migrating to JsInterop (get rid of jsni)
- migrating to Bootstrap 5
But I'm facing an issue with the following @JsFunction
import jsinterop.annotations.JsFunction;
@JsFunction
@FunctionalInterface
public interface FormatterCallback<T> {
String formatTooltip(T value);
}
When I declare it with lambda it fails
// using @JsFunction
slider.setFormatter(range -> "Range: [" + range.getAt(0) + "," +
range.getAt(1) + "]");
But if I declare it with JSNI it works
slider.setFormatter(rangeFormatter());
private native FormatterCallback<Range> rangeFormatter() /*-{
return function (value) {
return "Range: [" + value[0] + "," + value[1] + "]";
};
}-*/;
You can find the successful and the failing GWTTestCase here:
https://github.com/freddyboucher/gwtbootstrap3/blob/master/gwtbootstrap3-extras/src/test/java/org/gwtbootstrap3/extras/slider/client/ui/RangeSliderTest.java
<http://RangeSliderTest.java>
And of course the full projet
https://github.com/freddyboucher/gwtbootstrap3.git
When I log in the console the 2 functions it looks like that
===JSNI===
ƒ (value_0_g$){
return 'Range: [' + value_0_g$[0] + ', ' + value_0_g$[1] + ']';
}
===JsFunction===
ƒ (){
return samMethod_0_g$.apply(lambda_0_g$, arguments);
}
Any idea how to resolve it?
thanks
