Magento Category Filter Error

$category = Mage::getModel('catalog/category')->load($currentCategory->getId());

$_productCollection = $category->getProductCollection()->addFieldToFilter('genre', array('finset' => '126'))->addAttributeToFilter('category_ids',array('finset'=>'14'));

Mage::getModel('catalog/layer')->prepareProductColle开发者_运维技巧ction($_productCollection);
$_productCollection = $_productCollection->load();

The above statement is giving an error, please help me run this.

What are you trying to do exactly?

If you call $category->getProductCollection, you will only get the products in the category you loaded so no need for a category filter. I think for Magento above 1.4, category_ids doesn't exist anymore.
