he folks

iv got some strange problem here...
first the code
PHP Code:
        Ext.QuickTips.init();
        
        
extDialog = new Ext.Window({                // the window
            
title:"Dialog",
            
width:520,
            
closable:true,
            
collapsible:true
        
});
        
        
tabPanel = new Ext.TabPanel({                // the tabpanel 
                
id:"tabpanel",
                
xtype:'tabpanel',
                
border:false,
                
animScroll:true,
                
autoScroll:true,
                
draggable:false,
                
enableTabScroll:true,
         });
         
        
extDialog.show();
        
extDialog.on("resize",function(dlg,w,h){dlg.getComponent("tabpanel").doLayout()},extDialog)
        
extDialog.add(tabPanel);
        
        
extPanel = new Ext.Panel({                        // the panel
                
id:"panel",
                
title:"panel",
                
closable:true,
                
height:350,                                        // must set fixed height for displaying 
                
border:false,
                
layout:'border',
                
items:[{
                    
region:'center',
                    
border:0,
                    
xtype:'panel'
                
},{
                    
region:'south',
                    
split:true,
                    
xtype:'form',
                    
height:150,
                    
hideLabels:true,
                    
hideBorders:true,
                    
method:'POST',
                            
layout:'form',
                    
url:"",
                    
items:[{
                            
xtype:'htmleditor',
                            
fieldLabel'',
                            
name'message',
                            
allowBlank:false,
                            
enableSourceEdit:false,
                            
anchor:'0-50'
                        
},{
                            
xtype:'hidden',
                            
fieldLabel'',
                            
name'attr',
                            
allowBlank:false
                    
}],
                    
buttons:[{
                        
text:"Send"
                    
}]    
                }]
        });
        
        
tabPanel.add(extPanel);
        
tabPanel.activate(extPanel.id);
        
extDialog.doLayout(); 
the problem is, if i resize the window, the tab wont resize (x axis works, y axis wont).
i figured out that is has todo with the explicit height-setting of the panel
if i dont set the panels height, nothing will be displayed

what i want?
correct resizing of tabs inside the windows tabpanel

maybe someone could give me a hint, to solve this problem
