This is the second dialog

var viewMessage = function(){
    var dialog, showBtn;
    
    return {
        init : function(){
        	             
             
        },
       
       showDialog : function(){
            if(!dialog){ // lazy initialize the dialog and only create it once
                dialog = new Ext.BasicDialog("msg-dlg", { 
                        
                        width:500,
                        height:350,
                        shadow:true,
                        minWidth:300,
                        minHeight:250,
                        proxyDrag: true
                });
                dialog.addKeyListener(27, dialog.hide, dialog);              	 
                dialog.addButton('Close', dialog.hide, dialog);
                
             
             
            }
           // dialog.show(showBtn.dom);        
            
             }
       
    };
}();

Ext.onReady(viewMessage.init, viewMessage, true);

IM calling it with this from a rowClick function from a grid in my origonal dialog:

viewMessage.showDialog()
