Eliom_client_valueSourceSee the manual.
An 'a client value on the client is just an 'a. See also the abstract representation on the server.
This exception is raised (in Lwt) on the client if a call to a server function Eliom_client.server_function fails (in Lwt) on the server side.
The argument describes the original exception by Printexc.to_string.
Event handlers like Eliom_content.Html.F.a_onclick may raise False to cancel the event (as if the JavaScript function returned false).
