Error: cannot extend JsFunction implementation

[Manuel Carrasco Moñino]

Is there any reason why a Class implementing a JsFunction cannot be extended or it is a bug?

In the @JsFunction documentation there is nothing about this constrain.

@JsFunction
interface I {
  void call(...);
}
class A implements I {...}
class B extends A {...}

[ERROR] : 'A' cannot extend JsFunction implementation 'B'.

Thanks

Works as intended.

Any form of polymorphism is avoided in JsFunction design so that we could generate a simple javascript function out of it: https://gwt-review.googlesource.com/#/c/12810/

Gotcha. So the javadoc should say something about this constrain

Thanks
