and in main view calling as:

{ region: 'center', xtype: 'gridpanel',

            listeners : {                 itemdblclick: function(dv, record, item, index, e) {                      var = record.data;                     win = ext.create('app.view.popupwindow');                      console.log(win.myextraparams);                      win.on('show', function(win) {                       win.settitle(record.get('id'));                     });                      win.show();                 }             },               columns: [                       ****                     ],             store: 'mainstore',              height: 100,             width: 400,          } 

i want populate fieldset in kopfdatenview. kindly

you directly pass record window on creation :

win = ext.create('app.view.popupwindow', {     myrecord: record }); 

and inside window's initcomponent function (before callparent) :

this.title = this.myrecord.get('id');
