无法以编程方式创建优惠券代码

I am creating coupon code(shopping cart rule) programmatically in Magento Enterprise ver. 1.12.0.2.

Coupon code gets created without any problem.

But when I add the condition with the third rule i.e "1--1--1" as shown below and execute it, It gives error as

"Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (dbname.salesrule_product_attribute, CONSTRAINT FK_SALESRULE_PRODUCT_ATTRIBUTE_RULE_ID_SALESRULE_RULE_ID FOREIGN KEY (rule_id) REFERENCES salesrule (rule_id) ON DELETE C)' in D:\wamp\www\projectname\lib\Zend\Db\Statement\Pdo.php".

My code for condition is as shown below:

  $conditions = array(
        "1" => array(
            'type' => 'salesrule/rule_condition_combine',
            'aggregator' => 'all',
            'value' => 1,
            'new_child' => false
            ),
        "1--1" => array(
            'type' => 'salesrule/rule_condition_product_found',
            'value' => 1,
            'aggregator' => 'all',
            'new_child' => false
        ),
        "1--1--1" => array(
            'type' => 'salesrule/rule_condition_product',
            'attribute' => "category_ids",
            'operator' => "!=",
            'value' => "10"
        )
    );
$rule = Mage::getModel('salesrule/rule');
....
...
$rule->setData('conditions',$conditions);
$rule->loadPost($rule->getData());
$rule->save();

Can anyone help on this?

If you're not using it, I believe that disabling the Enterprise Rewards module can sometimes fix this PDO exception error. Try following this guide and see if it fixes your issue.
