    } });

from sencha api documentation:

any component within formpanel can configured formbind: true.

the problem using attribute formbind outside form component

you can correct code in way:

ext.define("sessionform", {     extend: 'ext.window.window',     alias: 'widget.sessionform',     // ...     items: [{         xtype: 'form',         items: [{             // form items         }],         buttons: [{             xtype: 'button',             text: 'save',             formbind: true,             handler: function (button) {                 // should rewrite following line                 // make independant components structure                 var form = button.up().up().down('form');                 form.updaterecord();                 button.up('window').destroy();             }         }, {             xtype: 'button',             text: 'cancel',             handler: function (button) {                 button.up('window').destroy();             }         }]     }] });

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
