I have been working with the Magento E-commerce platform and have to say it’s generally pretty slick. I ran into a problem though when trying to get the Google Checkout integration working. The error message in the Google Checkout integration console was:

"We were looking for data in your merchant-calculation-results, but were not
able to find it: result: address-id: XXXXXX"

The problem was that the XML response Magento was sending back had the correct calculations for each shipping method that was available but it didn’t include the shipping methods that were not available for the address. These are required according to the Google Checkout XML API Docs.

The error was caused because I had created my own version of NamedFrame so that I could better control the size of it. Apparently in the new GWT the setElement() is no longer used, and instead replaceElement() is called. However the replaceElement() method is package private so I cannot call it from my own NamedFrame. The fix – just don’t fiddle with frame sizes (for now).
