add success property or callback to my own function

[pasblin]

how can i add a property or callback to my own function?? thx

[Estefan]

create the callback object:

// the type of the object depends on the return type oh the method implemented on the server side
AsyncCallback<Boolean> callback= new AsyncCallback<Boolean>() {

public void onFailure(Throwable caught) {
//communication failed
MessageBox.alert("failure", "", null);
}

public void onSuccess(Boolean result) {
if (result == true) {
MessageBox.alert("Success", "", null);

}
}
};
