Hello everyone,
I have probably found a bug that is related to copy/modify/return and the
java-binding.
Anyway, I couldn't narrow down the problem any further.
With the following XQuery-Code I get the result “<A>0</A>” in BaseX 10.4 - as
expected.
In BaseX 12.0 I get an error message “Cannot invoke
”org.basex.query.func.XQFunction.arity()“ because ‘func’ is null”.
(: schnipp :)
declare namespace ll = "java:java.util.LinkedList";
declare variable $linkedList := ll:new();
copy $test := <A>{ll:size($linkedList)}</A>
modify ()
return $test
(: schnapp :)
