The Submit form at https://remora-reskin.stage.mozilla.com/en-US/firefox/addon/1865 lets you submit " " with a rating value of 'choose'. Conversely, the form-checking behavior at https://remora-reskin.stage.mozilla.com/en-US/firefox/reviews/add/1865 insists that "The rating must be a number". Pretty sure, then, we should change https://remora-reskin.stage.mozilla.com/en-US/firefox/addon/1865 to not accept "choose" as a value.
Meant to add: "choose" isn't currently a value in https://remora-reskin.stage.mozilla.com/en-US/firefox/reviews/add/1865 and friends; that's covered by bug 417445, and bug 417442 more generally covers the discrepancy between the way ratings are currently implemented.
This is related to bug 417445
patch to bug 417445. does not accept choose as a value on both forms. If that patch is okay this bug would be resolved to
patch to 417445 has been committed so should also have fixed this bug
