Hi,
I'm assigning a Java method M to a JS Callback. If M is static it
works. If M is non-static I get an error when calling the M via JS.
// THE BASE CLASS
package com.egr.x4gpl.apps.saturn.client;
abstract class Application {
protected Application(String pUnused) {
initializeCBs();
}
protected native void initializeCBs() /*-{
$wnd.x4ResizeAppCB =
[email protected]::resizeCB();
$wnd.x4ResizeAppCB();
}-*/;
abstract public void resizeCB();
}
// THE DERIVED CLASS
public class Saturn extends Application implements EntryPoint {
Saturn() {
super("Unused");
}
public native void resizeCB() /*-{
$wnd.alert("non-static invoke");
}-*/;
// THE ERROR (on calling, not on assingment)
[ERROR] Failed to create an instance of
'com.egr.x4gpl.apps.saturn.client.Saturn' via deferred binding
com.google.gwt.core.client.JavaScriptException: (RangeError): Instance
method 'resizeCB' needed a qualifying instance (did you forget to
prefix the call with 'this.'?)

Method)
at com.egr.x4gpl.apps.saturn.client.Application.<init>
(Application.java:5)

TIA for any kinda support!
