If you mean that your function appears to never run at all, it may be because
it never runs. When a function call mysteriously never runs, even though you
know the call to it was reached, this is usually a side-effect of function
mapping.
If you declare a function argument that is typed as a singleton (one and only
one value allowed) and you pass a sequence to that function, then the function
is invoked once for each item in the sequence. If the sequence is empty, it has
zero items and so the function is invoked zero times.
For example:
declare function foo ($blah as xs:string)
{
fn:concat ("Hello ", $blah)
};
foo (())
In this code, the function foo() will never run.
You can test this by disabling function mapping in your module by declaring
the following option in the prolog of your module. With this, passing a null
pointer
will result in an exception in your code.
declare option xdmp:mapping "false";
Hope that helps.
