Hi Hans-Jürgen,
Thanks for the observation. A simplified version of your query is:
let $a := 'x'
let $b := if($a) then (<a/>, <b/>) else error()
return $b/name()
The problem has been fixed in the latest snapshot [1].
Best,Christian

Dear BaseX people,
I have encountered a bug (?). Please consider this code:
= = = = = = = = = begin = = =
declare namespace f="http://weatherreport.org/heavyweather"; declare
function f:relatedNames($node, $relationship) as xs:string* { let $fnName
:= function($node) { let $_DEBUG := trace(count($node),
'#node: ') return name($node)} let $items :=
switch($relationship) case 'child' return $node/* default return
error() return $items/$fnName(.) => distinct-values() => sort() =>
string-join(', ')};
let $doc := <doc><a/><b/><c/></doc>return f:relatedNames($doc, 'child')
= = = = = = = = = end = = =
= = = = = = = = = output = = =#node: 3Stopped at
C:/projects/foxpath-examples/pre-balisage/problem-basex2.xq, 15/25:[XPTY0004]
Item expected, sequence found: (<a/>, <b/>, <c/>).= = = = = = = = = = = = = = =
=
The call $fnName(.) receives a single item, but three items arrive at the
function item!
With kind regards,Hans-Jürgen
PS: The funny switch() seems to play a part in the game, when I removed it, the
issue vanished.PPS: BaseX 11.8 [Standalone]
