'Please specify a shipping method' error even by selecting the shipping method

[davidalves]

We are developing an extension for freight and it works well in the cart.

At the checkout the shipping options appear and can be selected normally, but when I try to close the purchase order an alert with the message 'Please specify a shipping method' appears, even though I have already selected the shipping method.

When I query the Freight Platform API it returns a code that I have to pass in the shipping method, for example, 'mycustomshipping_transporter_code'. When I send without the code, for example 'mycustomshipping_transporter', it works.

My code is like this:

$shipping_method = $this->_offer_token . '_' . $carrier->oferta;

/** @var Mage_Shipping_Model_Rate_Result_Method $rate */
$method = Mage::getModel('shipping/rate_result_method');

$method->setCarrier($this->_code);
$method->setMethod($shipping_method);

Anyone have any idea what might be happening?

Hi @davidalves,

Can you share the whole code of the class/shipping method?

Thanks, but I resolved this problem. I didn't know that the collectRates method was called every time the step was changed in the checkout, so when was changing the step, the API was responding with a different code and the Magento was losting the shipping method

The module is on github: https://github.com/davidalves1/freterapido_magento

Thanks for sharing the final solution.
