using group() breaks getSelectCountSql in magento

When I\'m using

$collection->getSelect()->group(\'entity_id\')

or

$collection->groupByAttribute(\'entity_id\')
<         


        

Answer 1

I made it without touching Core files by overriding the getSize() method of my collection.

public function getSize()
{
    if (count($this->getSelect()->getPart(Zend_Db_Select::GROUP)) > 0) {

        // Create a new collection from ids because we need a fresh select
        $ids = $this->getAllIds();
        $new_coll = Mage::getModel('module_key/model')->getCollection()
                ->addFieldToFilter('id', array('in' => $ids));

        // return the collection size
        return $new_coll->getSize();
    }

    return parent::getSize();
}

Tell me if that works for you..
