[fw-general] Add functions to Zend_Form_Element

[Milchbazi]

Hello,

I've tried to extend Zend_Form_Element without success. I want to add some
functions like

class Form_Element extends Zend_Form_Element
{
        protected $_unit = '';
        
        protected $_elementId;
        
    /**
     * Set element unit
     * 
     * @param  string $unit 
     * @return void
     */
    public function setUnit($unit)
    {
        $this->_unit = (string) $unit;
    }

    /**
     * Retrieve element unit
     * 
     * @return string
     */
    public function getUnit()
    {
        return $this->_unit;
    }
    
    /**
     * Set element id
     * 
     * @param  integer $elementId 
     * @return void
     */
    public function setElementId($elementId)
    {
        $this->_elementId = (string) $elementId;
    }

    /**
     * Retrieve element id
     * 
     * @return integer
     */
    public function getElementId()
    {
        return $this->_elementId;
    }
    
}

With those functions I can access the given unit in the decorator with
$this->element->getUnit(), that's what I'm trying to achiv. But
unfortunately I just can't find a smooth way to do it properly. When I use
$form->addPrefixPath it would work, but only if I redefine all
Zend_Form_Element_* elements.

By the way: My current quick and dirty solutions is to extend
Zend_Form_Element:


class Zend_Form_Element extends Form_Element implements
Zend_Validate_Interface 
{}


But this way I would have to update this file every time I'll do a SVN
Update of the framework...

Any solutions or suggestions?

Thanks in advance.
