Maybe specify a default value in the call to xdmp:get-request-field:
let $var := xdmp:get-request-field("non-existent-param","")

The point is that the function is never called (it is throwing fn:error just to
prove that it's not called, errors or not). Also, there is no warning that the
function is not being called, or that there is an error in the parameter.
Anyone know why this is? Try running the code and you'll see what I mean. It's
almost like there is a hidden try/catch around my code - no errors raised and
doesn't show that nothing was called.

Hi spig,
Not sure about fn:error(). Maybe approach with try get instead...?
try {
1 div 0
}
catch ($e) {
$e
}
Or just use an if then else for checking if your field exists...?
if(xdmp:get-request-field("q"))
then local:search-results()
else ...

Subject: [MarkLogic Dev General] Unexpected behavior
If I run the following code, my function is never called and no errors are
raised. Any ideas?
xquery version "1.0-ml";
declare function local:test($param1 as xs:string, $param2 as xs:string, $param3
as xs:string) {
fn:error()
};
let $var := xdmp:get-request-field("non-existent-param")
let $blah := local:test("", "", $var)
return "Function Call Successful"
Thanks,
Steve Spigarelli
