I'm trying to override the function _prepareCollection in Mage_Adminhtml_Block_Catalog_Product_Edit_Tab_Super_Config_Grid class

    <?php

class Ayasoftware_RequiredOptions_Block_Adminhtml_Catalog_Product_Edit_Tab_Super_Config_Grid extends Mage_Adminhtml_Block_Catalog_Product_Edit_Tab_Super_Config_Grid

{

     protected function _prepareCollection()

    {

         echo "testing if overridden ";

        $allowProductTypes = array();

        foreach (Mage::helper('catalog/product_configuration')->getConfigurableAllowedTypes() as $type) {

            $allowProductTypes = $type->getName();

        }



        $product = $this->_getProduct();

        $collection = $product->getCollection()

            ->addAttributeToSelect('name')

            ->addAttributeToSelect('sku')

            ->addAttributeToSelect('attribute_set_id')

            ->addAttributeToSelect('type_id')

            ->addAttributeToSelect('price')

            ->addFieldToFilter('attribute_set_id',$product->getAttributeSetId())

            ->addFieldToFilter('type_id', $allowProductTypes)

           // ->addFilterByRequiredOptions()

            ->joinAttribute('name', 'catalog_product/name', 'entity_id', null, 'inner');



        if (Mage::helper('catalog')->isModuleEnabled('Mage_CatalogInventory')) {

            Mage::getModel('cataloginventory/stock_item')->addCatalogInventoryToProductCollection($collection);

        }



        foreach ($product->getTypeInstance(true)->getUsedProductAttributes($product) as $attribute) {

            $collection->addAttributeToSelect($attribute->getAttributeCode());

            $collection->addAttributeToFilter($attribute->getAttributeCode(), array('notnull'=>1));

        }



        $this->setCollection($collection);



        if ($this->isReadonly()) {

            $collection->addFieldToFilter('entity_id', array('in' => $this->_getSelectedProducts()));

        }



        parent::_prepareCollection();

        return $this;

    }

}

in my config.xml I have this

    <?xml version="1.0"?>

<config>

    <modules>

        <Ayasoftware_RequiredOptions>

            <version>0.1.0</version>

        </Ayasoftware_RequiredOptions>

    </modules>

    <global>

        <helpers>

            <requiredoptions>

                <class>Ayasoftware_RequiredOptions_Helper</class>

            </requiredoptions>

        </helpers>

        <blocks>

            <requiredoptions>

                <class>Ayasoftware_RequiredOptions_Block</class>

            </requiredoptions>

            <adminhtml>

                <rewrite>

                    <catalog_product_edit_tab_super_config_grid>Ayasoftware_RequiredOptions_Block_Adminhtml_Catalog_Product_Edit_Tab_Super_Config_Grid</catalog_product_edit_tab_super_config_grid>

                </rewrite>

            </adminhtml>

        </blocks>

        <models>

            <requiredoptions>

                <class>Ayasoftware_RequiredOptions_Model</class>

                <resourceModel>requiredoptions_mysql4</resourceModel>

            </requiredoptions>



        </models>

    </global>

</config>

the function _prepareCollection is overridden correctly, but still using the original function that does not filter by ->addFilterByRequiredOptions()

any idea how to fix this?
was working fine in older versions.
