[editor: moving to the appropriate forum…]

I keep getting the following fatal errors when trying run a dojo.require("dojo.widget.TabContainer"); or a dojo.require to load any other type of dojo widget (Dialog, etc.).

Here is the code I have on a jsp page which I call head.jsp which does all the common head type work for all my jsp pages on my website:

Please advise on how to avoid displaying these FATAL error messages and allow to load these widgets correctly. Thanks.

           dojo.require("dojo.widget.TabContainer");
           dojo.require("dojo.widget.LinkPane");
           dojo.require("dojo.widget.ContentPane");
           dojo.require("dojo.widget.LayoutContainer");
           dojo.require("dojo.widget.FisheyeList");
    
    

    
        var loadingDialog;
        var loadingDialogContents;
        var blockingDialog;
        function fadeAndBlockPage() {
            if (blockingDialog) {
                blockingDialog.show();
            }
            return true;
        }


        function fadeAndBlockPageTimeOut() {
            if (blockingDialog) {
                blockingDialog.show();
                setTimeout('blockingDialog.hide()',20000)
            }
            return true;
        }
