If I edit a Grouped product in a specific store view scope, then I can see 'Associated Products' tab and I can change the associated products. If I then save the product, then my update will have affected the Grouped product in ALL store views; this is because the Grouped->Associated Products relationships are stored in the 'catalog_product_relation' table and the relationships are not specific to website/store/store views.
Shouldn't Magento prevent updates to Associated Products when user isn't in the 'Default' scope?
The reason that this is a particular problem for me is that I'm using a module where admin users can be restricted to seeing a specific store view scope. The problem is that they can then affect Associated products in store views to which they don't have access.
