form.getValues - this.el is undefined

[ser]

I have a Window

		new Ext.Window({
		    title: 'My Window',
		    closeAction: 'hide',
		    width: 662,
		    height: 403,
		    layout: 'anchor',
		    boxMinWidth: 662,
			items: [
				{
					xtype: 'form',
					id: 'form-description-activity',
					name: 'form-description-activity',
					frame: true,
					items: [
						{
							xtype: 'fieldset',
							title: 'Атрибуты активности',
							layout: 'hbox',
							width: 634,
							layoutConfig: {

							},
							items: [
								{
									xtype: 'container',
									layout: 'form',
									width: 300,
									items: [
										{
											xtype: 'textfield',
											id: 'name',
											name: 'name',
											fieldLabel: 'Наименование',
											anchor: '100%'
										},
										{
											xtype: 'compositefield',
											fieldLabel: 'Начало периода',
											anchor: '100%',
											items: [
												{
													xtype: 'combo',
													id: 'startCycle',
													name: 'startCycle',
													flex: 1
												},
												{
													xtype: 'datefield',
													id: 'startDate',
													name: 'startDate',
													format: 'd.m.Y',
													flex: 1
												}
											]
										}
									]
								}
							]
						}
					]
				}
				]
	})

I need to get all the values of the fields.

My code is
var values = Ext.getCmp('form-description-activity').getForm().getValues();
and i get "this.el is undefined"
If I comment this line, the form is displayed correctly. What's wrong? Thanks.

use ExtJS 3.2.1

You can only call getValues() after the form has rendered.

ps. Calling getFieldValues() should be possible before the form is rendered.

Excellent, working. Thanks, you saved my life!

var form = Ext.getCmp('form-description-activity').getForm();
form.findField('name').setValue(record.name); // it's worked
form.findField('startDate').setValue(record.startDate) // form.findField('startDate') is null.

Why did not he finds startDate? The form of the above.

CompositeField is not a container, so it can't find fields inside it (this is currently listed as a bug).

I recommend using a hbox container instead of a CompositeField.

OK. Thanks.

I'm painfully aware of this issue in Ext JS 3.x - we're changing things in Ext JS 4.x so that you no longer have to render a form before interacting with its data. CompositeField will also go away as it will no longer be necessary to achieve more advanced form layouts.

nice to hear, form handling is very tricky but shouldn't.

I feel your pain. We have a great solution coming in 4

is it the same like the approach in sencha touch?

Btw - yesterday i saw your talk (http://pivotallabs.com/talks/109-sencha-touch) - very nice! I have to start with touch to be ready
