Hello!

In buildForm i'm calling the googlemap field type which is a custom field
(called by service container) type with 3 fields into:

$builder

->add('gmap_position','googlemap',array('dbrow'=>$builder->getData(),'mapse ttings'=>array('map_id'=>'map_canvas','width'=>'600px','height'=>'400px')))
            ->add('text','ckeditor')
            ->add('status','status')
        ;

The google map field type is here - i'm adding 3 fields in the form builder
- but get the error

You cannot add children to a simple form. Maybe you should set the option
"compound" to true?
