I've already seen people reporting this, but I cannot reproduce it by using commerce coupon myself. I guess this is caused by an incomplete cache caused by cache-rebuilding issues.

Try inspecting your entity info and entity property info caches and check whether they are complete.

Issue summary: View changes

Hi @fago, it seems very generic issue for the entity API + Cache, for my case

- Once a og(organic group) is associated with a node
- Now clear the cache
- Node view page breaks as *Unknown data property type*, now if I check from console for this particular
node id as *drush eval "print_r(entity_metadata_wrapper('node',node_load([nid]))->getPropertyInfo())"*
no basic properties nodes are available in the array structure
- now execute *drush registry-rebuild* & *drush cc all* then only can see the all the properties of node for the above snippet

Note: I'm using PHP 5.6.30 version

Is there anything related PHP compiler of this version that cache behaves inconsistently & breaks the registry as well.
But in my lower environment(PHP-5.3) that doesn't have such issue.

Regards,
Nilanjan
