Make sure you modify the following native method to point to your own
package structure:
public native void setMyOnload(JavaScriptObject elm, MyNamedFrame
frame)/*-{
elm.myonload = function(event){
[email protected]::onload(Lcom/
google/gwt/user/client/Event;)(event);
};
}-*/;
You need to modify "com.skystrider.subtabs.client.gwtUtils" to the
package structure location that you have MyNamedFrame stored.
