Product won't save. Processing forever

Question

I'm doing a module to Magento my module have the same functions of Crosssell native function from magento. I have this product grid and the user select some checkboxes to associate this products to the main product. All ok.

But, I've create a custom attribute to save the ID's of this products and make a Observer to 'catalog_product_save_after' event:

  <events>
        <catalog_product_save_after>
            <observers>
                <brindeproduto_save_product_data>
                    <type>singleton</type>
                    <class>brindeproduto/observer</class>
                    <method>saveProductTabData</method>
                </brindeproduto_save_product_data>
            </observers>
        </catalog_product_save_after>
    </events>

On my saveProductTabData I load the main product by the ID on Request, and put the IDS of the selecte products on my custom attribute like these "1,2,3,4,5,6".

Ok, but when I do $product->save(); I got infinite load on my browser, without any error or exeption. The code on observer are simple.

$product = Mage::getModel('catalog/product')->load($product_id);
//some logical Specific information that is not in question now.
$product->save();

Nothing more.

I've tryed debug the save function and get some intriguing result. On Mage_Core_Model_Abstract function save(), I put some die on parts of code, and get all of then. this code it's part of function save line 330 on Magento 1.5 Community.

    if ($dataCommited) {
        $this->_afterSaveCommit();
    }
    return $this;

It's the last line on function. I put die before return.

    if ($dataCommited) {
        $this->_afterSaveCommit();
    }
    die('test');
    return $this;

I've got the die. But nothing more before return. Some body have ideia of what's happen?? Lost by 5 hours on that. Any help will be mutch appreciated.

Answer 1

You should NOT be doing any save in your observer (*_save_after).

This will cause a never ending loop
