TextField.setHieght(100); Doesn't work in ie?

[mhmda]

I use this code to set a textfield height, but it doesn't work in IE (8),
Any one know why?

The code below works as expected for me on I.E. 8. Maybe you have a CSS or layout issue?:

var xx = Ext.create('Ext.window.Window', {
  bodyPadding: 5,
  height: 150,
  width: 400,
  items: [{
    xtype: 'textfield',
    fieldLabel: 'Last Name',
    name: 'lastName',
    width: 250
  }]
}).show();

xx.down('textfield').setHeight(100);
