Hi there!
Can anyone help me with the error mentioned above?
I try to make an interface to JavaScript so I can call a function. My
Java code looks like that:
public void onModuleLoad() {
setShowTrigger(this);
}
public native void setShowTrigger(Index x)/*-{
$wnd.showIndex = function () {
website.client.Index::runApp()();
};
}-*/;
public void runApp() {
Window.alert("I am a GWT function");
}
As soon as I add the method "setShowTrigger" it crashes with the
following error. Do I have to include a special library? Or is there
another way to call a GWT function from the HTML part?
