Would have no clue by that little information. What are you doing to cause this error?

i have a border layout , and i'm implementing a MVC like system . i.e i don't have any mvc , and only i replace content of center region :D
i have a accordion in east region that i use it such menu with button items .


var centerRegion = Ext.ComponentQuery.query('viewport panel[region="center"]')[0];
// get a reference to any existing content.
var existingContent = centerRegion.getComponent(0);
// if found, remove it.
if (existingContent != null) {
centerRegion.remove(existingContent);
}
// now add new content, based on clicked button.
if (button.text == '?????? ????') {
//userrealstore.load();
centerRegion.add({
xtype: 'panel',
id:"start_account",
layout: {type: 'vbox',align: 'center' },//layout: 'ux.center',
autoScroll: true,
bodyStyle: 'padding:20px;',
items: [begin_form]
});

and so on .
my problem is : After I click the menu items two or three times, centerRegion will be disapear and I get this error message !!!
and error in google chrome is :
