using group() breaks getSelectCountSql in magento

Question

When I\'m using

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

or

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


        

Answer 1

I have solved this using the function below:

public function getSize()
{
    return sizeof( $this->getAllIds());
}

This helped me in issue of getSize() returning 1 count of product collection in Magento CE 1.5.

I have overwritten the Mage_Catalog_Model_Resource_Eav_Mysql4_Product_Collection file and place above function.
