xtype:'container' rendering problem

[Sameer Khan]

Hi, I add some elements to container class.. After installation of xxx.apk file on galaxy tab when i rotate galaxy tab in Landscape or Portrait mode its not rendering properly...
My Code is:
{
xtype: 'container',
layout:'hbox',
defaults:{labelWidth:'80%',labelAlign:'right'},
items:[{
xtype: 'radiofield',
label: 'RN',
name: 'supervisoryrn',
labelAlign: 'right',
value:'0',
flex:1,
labelWidth:'78%',
},{
xtype: 'radiofield',
label: 'Aide',
name: 'supervisoryrn',
labelAlign: 'right',
value:'1',
flex:1,
},{
xtype:'component',
html:'<h2 class="fieldbar">was</h2>',
}]
}

What isn't rendering properly? I have heard of orientation problems with phonegap and android. Part of the reason ST2 was created after a year.
