View Full Version : IE 8: Initially hidden CompositeField inside a FormPanel get 0 height on display

12 Apr 2013, 1:46 AM

Ext version tested:

Ext 3.4.0

Browser versions tested against:

IE8 - doesn't work
Chrome 26.0.14 - works


IE 8: Container (form layotu) nested in a FormPanel does not calculate correct height for a nested composite field but sets 0 height instead.

Steps to reproduce the problem:

Create FormPanel {defaults: {hidden: true}} with a Container {layout:'form'} and a nested CompositeField with two fields
Show the form and change the visibility at runtime

The result that was expected:

Composite field is visible with a correct height

The result that occurs instead:

Composite field has 0 height

Screenshot or Video:


Debugging already done:

Apparently, FormLayout does not call box.component.setSize() since calculated height is undefined and calculated width didn't change since last calculation. When calculating in Chrome the width does change couple of px, that causes box.component.setSize(), and consequent adjustmentPass on the FormLayout.

Possible fix:

set the height manually on show

Additional CSS used:

only default ext-all.css

Operating System:

Win 7
