    Default [FIXED] [GWT 2.0m1] Attaching CheckBox to Container throws runtime exception

    [FIXED] [GWT 2.0m1] Attaching CheckBox to Container throws runtime exception


    Looks like simply attaching a CheckBox to a Container throws a RuntimeException.

    - GXT version: 2.0m1
    - GWT version: 1.6.4
    - Hosted mode
    - Red Hat Fedora 8

    Sample code
    Code:
    public class Test implements EntryPoint {
    
        /**
         * This is the entry point method.
         */
        public void onModuleLoad() {
        
            ContentPanel panel = new ContentPanel();
            CheckBox checkBox = new CheckBox();
            panel.add(checkBox);
            
            RootPanel.get().add(panel);
        }
    }
    Stack trace:
    Code:
    [ERROR] Uncaught exception escaped
    java.lang.RuntimeException: Failed to invoke native method: @com.extjs.gxt.ui.client.core.El::getAlignToXY(Lcom/google/gwt/user/client/Element;Ljava/lang/String;[I) with 3 arguments.

    This is already fixed in SVN.

    If it is urgent for you to get bugfixes as fast as possible you can consider to get a support subscription.
