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]
