extjs4 - Extjs window close event -


i have window cancel button , default close[x]. when user clicks cancel button, should check specific flag , close window , updates db. using me.close(this); closing window cancel button. when user clicks on [x], should check same flag , updates db , close window. checking flag condition, added listener listener works fine. after adding listener, clicking cancel button, close event called twice. db updation happens twice. advice me how handle [x] close event window

ext.define('myapp.view.updateform', {     extend: 'ext.window.window',     height: 600,     width: 800,     layout: {         type: 'absolute'     },     title: 'update window',     modal: true,     initcomponent: function() {          ext.applyif(me, {             items: [                 {                     xtype: 'button',                     id:'btncancel',                     handler    : function(){                         if(flag == true){                             //add db                             me.close(this);                                                         }                     }                 }]         });             me.callparent(arguments);     },      listeners:{         close:function(){             if(flag == true){                 alert("close window");                 //add db             }         }     }  });

i have done exact implementation minor differences , can attest works expected.

here code:

 ext.create('ext.window.window', {       ...       buttons:[             {                 text:'finish',                 handler:function () {                     this.up('window').close();                 }             }        ],        listeners:{             close:this.somefunction,             scope:this         }       ....

this works perfectly. tells me issues elsewhere in code.
