jsConstructor returns undefined

[pavel....@gmail.com]

Hi all,

I have noticed that the next code returns the undefined value in gwt 2.9.0

public static native <T> Object getCtorFn(Class<T> cls) /*-{
$wnd.console.log(cls)
$wnd.console.log(cls.@java.lang.Class::jsConstructor)

return cls.@java.lang.Class::jsConstructor;
}-*/;

Does someone know is jsConstroctor still supported?

Or could be there is another way to achieve the same

You can use jsinterop-base library. It has a method 'Js.asConstructorFn(Class)'

…which uses cls.@java.lang.Class::jsConstructor, so if it's null/undefined in your own JSNI, there's no reason it won't be in jsinterop-base's JSNI: https://github.com/google/jsinterop-base/blob/3db256c87fea1b90786451b1814f6354bb39f370/java/jsinterop/base/InternalJsUtil.java#L164-L166
