* title: "FormLayout Panel",
* layout: 'form',
* renderTo: Ext.getBody(),
* bodyPadding: 5,

* items: [{
* fieldLabel: 'First Name',
* name: 'first',
* allowBlank:false
* },{
* fieldLabel: 'Last Name',
* name: 'last'
* },{
* fieldLabel: 'Company',
* name: 'company'
* }, {
* fieldLabel: 'Email',
* name: 'email',
* vtype:'email'
* }, {
* fieldLabel: 'DOB',
* name: 'dob',
* xtype: 'datefield'
* }, {
* fieldLabel: 'Age',

* }, {
* xtype: 'timefield',
* fieldLabel: 'Time',
* name: 'time',
* minValue: '8:00am',
