Error on deleting a service with File inputs

[vincent-lefort]

It's impossible to delete a service with a "File input". It raise this error :
Cannot query "Data type (ListParam)": Must be "FileInput" instance.

There is a workaround: go on submissions methods, delete all "File inputs" one by one, then go back to services page to delete the service.

Sorry I could not reproduce. Can you be more specific ? (sent email with screenshots)

Though I found another issue while searching for this one. The delete button was active but with no effect.

From WAVES back-office: 'Home' click 'Services'.
Select a service with the check-box then select 'Delete selected services' in the 'Action' dropdown list and click the 'Go' button. This raises the error.
