Hello there,

I am trying to use xquery:eval method supplying bindings as map, and following the example on the website where the bindings are supplied as a map. However, when I run the following query, I get the error "Items of type map(*) cannot be atomized". What am I doing wrong?

(:Filter out the required diagrams from $diagrams:)
declare variable $depotConstraint external := "OC";
declare variable $resConstraint external := "NIL";
declare variable $lowerDiagNoConstraint external := "NIL";
declare variable $upperDiagNoConstraint external := "NIL";

(:Bindings for diagramSelectionCoR.xq:)
declare variable $bindings := map {
  xs:QName("depotConstraint") : $depotConstraint, 
  xs:QName("resConstraint") : $resConstraint, 
  xs:QName("loweDiagNoConstraint") : $lowerDiagNoConstraint, 
  xs:QName("upperDiagNoConstraint") : $upperDiagNoConstraint};

declare variable $diagramSelection := xquery:eval(file:read-text("D:\\XQuery\\VPExchange Queires\\diagramSelectionCoR.xq", $bindings));

$diagramSelection

For completeness, the query being loaded in the $diagramExchange "xquery:eval" is:

declare default element namespace "http://www.scfy.com/TTVP_Interface";

declare variable $date := "2017-07-10";
declare variable $daysRun := 3;

declare variable $depotConstraint external := "NIL";
declare variable $resConstraint external := "NIL";
declare variable $lowerDiagNoConstraint external := "NIL";
declare variable $upperDiagNoConstraint external := "NIL";

declare variable $depots := tokenize($depotConstraint," ");
declare variable $resources := tokenize($resConstraint," ");
declare variable $lowerDiagNo := tokenize($lowerDiagNoConstraint," ");
declare variable $upperDiagNo := tokenize($upperDiagNoConstraint," ");
