Boolean values reset upon import

[marian-chemistdirect]

Hi, boolean values like yes/no are reset to default after import.

This doesn't happen for me, example:

// Import intial product.
Mage::getModel('api_import/import_api')->importEntities(array(array(
    'sku'               => 'boolean-reset',
    '_product_websites' => 'base',
    '_type'             => 'simple',
    '_attribute_set'    => 'Default',
    'name'              => 'Boolean reset',
    'price'             => '123',
    'weight'            => '123',
    'description'       => 'Boolean reset',
    'short_description' => 'Boolean reset',
    'status'            => Mage_Catalog_Model_Product_Status::STATUS_ENABLED,
    'visibility'        => Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH,
    'tax_class_id'      => 0,
    'resetme'           => 'Yes'
)));

// Now update the title.
Mage::getModel('api_import/import_api')->importEntities(array(array(
    'sku'  => 'boolean-reset',
    'name' => 'Updated title'
)),
'catalog_product',
Danslo_ApiImport_Model_Import::BEHAVIOR_STOCK);

The resetme attribute is default No, but is still Yes after second import (updating title).
