The CommonRate label is currently not used coherently throughout the application stack. The existing translations suggest that the commonly understood meaning of CommonRate is a rate as a tariff or day rate. However, in the product management GUI, the CommonRate label is used to demark the section where ProductRating setting are made.
The provided fix splits CommonRate into two labels, CommonRate and CommonProductRating. Also, the application/product/webapp/ form definition now references the CommonProductRating label.
Unfortunately, the patches have to be provided per affected file, i.e. two patches make this imporvement.
