cubicweb #2717842 generic error handling for custom/ad-hoc form/controller pairs [open]
Having ad-hoc form/controller pairs in cubes is a common pattern. However whenever the controller is accessed directly, without the form part (as it has its own addressable url) can yield weird KeyError crashes that needlessly worry the sysadmins ...
There should be some catch-all error handler up to these generic errors doing slightly better than just show a stack trace.
