We've recently hit a rather nasty issue where enabling UUID on a site with Commerce 1.2 instantly causes a fatal error on non-admin pages, particularly when the cart block is enabled.

The specifics of the error is as follows:

Error message: EntityMetadataWrapperException: Unknown data property commerce_product

Using Commerce Devel to get more info revealed the following:

EntityStructureWrapper->getPropertyInfo('commerce_product') entity.wrapper.inc:396
EntityStructureWrapper->get('commerce_product') entity.wrapper.inc:431
EntityStructureWrapper->__set('commerce_product', '3') commerce_product_reference.module:1080

call_user_func_array('node_page_default', Array) menu.inc:517

Commerce product display nodes have a commerce_product field by default. I'm wondering whether UUID is affecting the product display entity in some way that results in it losing its Commerce Product data property?

See #1441094 and http://www.drupalcommerce.org/node/1242 for more details.

I'm not sure how UUID would or could affect this. Can you provide some more information that would take us closer to a solution here?

Can you try using the latest version of UUID 7.x-1.x-dev?

I had a very similar error with uuid alpha 3 and organic groups 2.x. The latest uuid dev looks like took care of the issue.

Yeah, we've fixed a lot of small issues in the latest dev. @geoffreyr Can you also please test the dev to see if the error goes away?

I have not tested the dev, but the problem is caused by the uuid implementation of hook_entity_property_alter, after installing uuid the entity_property_info array became what is shown in the image. I will check the dev, but wanted to report what is causing the issue.

I'm using the dev version of UUID and that seems to work well with the current version of Drupal Commerce (1.3).

I'm closing this one, since the latest version of UUID 7.x-1.x-dev seems to work with Commerce 1.3, telling from geoffreyr's comment. Please re-open if there's still problems after upgrading.
