Most of our developers turn it off in all our code unless there is a specific reason to use it and then, and only then, we turn it on.

Looks like this is a common gotcha. I think we'll disable it in all our code :) Cheers, -Steve On 21/05/2010 11:22, Sam Neth wrote: Function mapping. Here's a recent thread about this topic: http://markmail.org/thread/n2eyj2t56fmor7to On May 21, 2010, at 3:06 AM, Steve Mallen wrote: Hi folks, Does anyone know how Mark Logic deals with function signature type checking when calling functions? I ask because I recently went on a bit of a wild goose-chase debugging session, the result of which was that a function we'd defined was not being called at all (because of a mismatch in the types of the arguments being passed). There was no type error raised by ML. As a test case, I've createed the following XQuery, which gives an error in Saxon: declare function local:blah($foo as xs:string) { concat($foo, " called") }; local:blah( () ) Error: "An empty sequence is not allowed as the first argument of local:blah()" But when I run this against ML 4.1, the whole module just returns the empty sequence (and doesn't appear to call the function at all). There is no error raised. Can anyone help explain this behaviour? I would have expected a type exception to be thrown... am I missing something?
