[FIXED]formBind on button in FormPanel

[rchloupe]

I'm putting formBind on button in a formPanel, however, the button is not disabled when the page is first displayed. To get the button to be disabled I have enter invalid data into a form field.

Ext.create('Ext.form.FormPanel', {
	items: [{
	    xtype: 'textfield',
	    fieldLabel: 'First Name',
	    allowBlank:false
	}],
	buttons: [{
	    text: 'Save',
	    formBind: true,
	    handler: function() { console.log('click'); }
	}]
}).render(document.body);

This should be fixed in the next release.
