If the object cannot be built or if the _hmac is invalid (IIRC) extbase 
is forwarding the request to the referring action/controller - but in 
your case this should be "Supplier->new" and not the index action.

Could you please debug your "switchableControllersAndActions" in the 
backend module? Maybe there is something wrong/missing.
