Google Checkout Throws Errors relating to cart items.

Same story here with 6x.2.2 , I noticed errors in recent log entry section:

	php	03/31/2010 - 12:30	Duplicate entry '16' for key ...	Customer	
	php	03/31/2010 - 12:30	Illegal offset type in ...	Customer

Payment received fine, but I don't know if customer can see this errors as well

I am getting the same behavior. In version 6.x-2.2, the line for the first error has changed to 1337 in uc_cart.module.

function uc_cart_get_contents($cid = NULL, $action = NULL) {
  static $items = array();
  $cid = $cid ? $cid : uc_cart_get_id();

  if ($action == 'rebuild') {
    unset($items[$cid]);
  }

  if (!isset($items[$cid])) { // <------ right here

This is definitely happening when a customer makes it over to Google Checkout but I'm not sure it is directly related to that module. Another clue is that I got a blank email after the customer finished checking out.

I am going through the code and trying to backtrack through all of the places that uc_cart_get_contents() is called, but I really hope that someone else might already have a good idea about where this is happening.

Okay, I found the problem.

I have to admit that I'm a little frustrated because it turned out to be the same problem that I tracked down last year:

This time, I have gone as far as to create a patch of my fixes. I would really appreciate it if someone could get this patch into the next release.

Thanks! Applied the path, will see if it's work when I'll get an order.

Is it possible to test it somehow?

You should set up a Google sandbox account for testing purposes. Then, you should switch to test mode in the Ubercart Google Checkout settings and put in the Merchant ID and Key for the sandbox. That way you can run as many tests as you need without creating any real transactions.

Just received new order via Google Checkout today, but I can't see ANY action in log files. User account has been created, stock has been decreased, google checkout is marked as paid (also on ubercart) but there is none information in website admin recent log file. It should be at least note about new user account or new order.

So looks like path nr. 3 is working so far, no error after update, thanks!

This needs a bump and a review as it is still an issue in the current dev version.

This corrects issues with current dev and google API 2.4.

Committed. Thanks.
