Zend_Form global decorators overriding per element decorators when using array of optio

Hello.

I've been playing with Zend_Form today, specifically with
the text
decorators, however it's not behaving quite how I expect.

I've extended the Zend_Form class, and I create the form
using an array of
options, like so:
class forms_MediaOutletForm extends Zend_Form
{

        public function __construct($options = null) {

                $loader = Zend_Registry::get('loader');

                $loader->load('FormUtils');

                parent::__construct(array(
                        'action' =>
'/mediaoutlet/process',
                        'method' => 'post',
                        'decorators' => array(
                                'FormElements',
                                array('HtmlTag', array('tag'
=> 'p')),
                                ),
                        'elementDecorators' => array(
                                       
array('ViewHelper'),
                                        array('Errors'),
                                        array('Label',
array(
                                               
'requiredSuffix' => ' *',
                                                'class'
=> 'leftalign',
                                        )),
                                        array('HtmlTag',
array('tag' =>
'div', 'class' => 'field')),
                                ),
                        'elements' => array(
                                'MediaOutletId' =>
array('hidden', array(
                                        'validators' =>
array(
                                                'digits',
                                        ),
                                        'readonly' =>
true,
                                )),
                                'Name' => array('text',
array(
                                        'validators' =>
array(
                                               
array('stringLength', false,
array(3,70)),
                                        ),
                                        'filters' =>
array('StringTrim'),
                                        'required' =>
true,
                                        'label' =>
'Name',
                                )),
                                'CompanyID' =>
array('select', array(
                                        'validators' =>
array(
                                                'notEmpty',
                                        ),
                                        'required' =>
true,
                                        'MultiOptions'
=>
Companies::getIDName(array("Publisher")),
                                        'label' =>
'Publisher',
                                        'decorators' => 
array(
                                               
array('ViewHelper'),
                                               
array('Errors'),
                                               
array('Label', array(
                                                       
'requiredSuffix' =>
' XXX',
                                                       
'class' =>
'leftalign',
                                                )),
                                               
array('DivTag' => 'HtmlTag',
array('tag' => 'div', 'id' => 'company_div' )),
                                        )
                                )),
),
                ));
        }
}

What's happening is that the specific element decorate is
being overridden
due to the setOptions method in Zend/Form.php doing this:
$this->setElementDecorators($elementDecorators);

after all the elements are set.  This is causing my specific
element
decorators to be overridden.

Does anyone have any ideas on how I can do what I'm wanting
while staying
with this method of form configuration?

Cheers,
Jonathan.

Zend_Form::setOptions() delays the setElementDecorators()
call to after
all other configuration, so that any elements set using
configuration
will then be affected by it. There is no way to override
it.

An easier approach is to define an array of default
decorators you want
to use as an class property:

    public $defaultElementDecorators = array(...);

Then, omit your elementDecorators declaration, and declare
your
decorators for each element by referencing this property:

    'foo' => array(
        'decorators' =>
$this->defaultElementDecorators
    ),

For elements where you want custom decorators, you do as you
were doing
previously.

Right, that's what I suspected.

I had considered this but I wondered if there was a better
way to manage it
without duplicating configuration 
on each element.

If that's the most straight forward way to do it then great,
that's how it
shall be done 

Thanks for getting back to me so quickly.
Jonathan.
