product grid renderer multiselect attribute value

Question

Following this tutorial, I try to get values of multiselect attribute in a product grid.

Products have some selected values for this attribute and the 'filter_condition_callback' for this column work.

In the renderer I use below code but in the grid I get an empty list.

I hope someone can help.

public function render(Varien_Object $row) {

    $colors=explode(',',$row->getColors());
    $suppstr="";
    if(count($colors)>0)
    {
        $suppstr="<ul>";
        foreach($colors as $value)
        {
            $attribute = Mage::getModel('eav/config')->getAttribute('catalog_product', 'colors');
            if ($attribute->usesSource()) {
            $suppstr   .= "<li>".$attribute->getSource()->getOptionText($value)."</li>";
            }

        }
        $suppstr   .= "</ul>";

    }
      return $suppstr;    

}

It seems like you dont have set option values for your store. Try,

$storeId   = 0; // Your Store Id
$suppstr   .= "<li>".$attribute->getSource()->setStoreId(0)->getOptionText($value)."</li>";
