Yes Sure,
I have a Home class that extends EntryPoint and onModuleLoad(), I created a
button which calls a native java Method who's implementation is in js file.
This is that Js file,
window.Home = {
getRevertName: function (name) {
var test = new com.test.jsinterop.Entity(1,'test');
return name + test.getName();
}
}
this works file when I am simply returning some text. But when I am calling
the previously mentioned Entity class from this Js method it is throwing an
error. What I want is to call the Entity from my js file.
I am not sure how to add -generateJsInteropExports to the compiler.
Althrough I did put <set-configuration-property name="generateJsInteropExports"
value="true"/> in my module.gwt.xml file.
Yes no problem with Integer or int. I did replaced all the instances of
Interger to int.
