Hello Shaun,
seems like a simple mistake with your parathesis. It should be:
declare variable $diagramSelection := xquery:eval(file:read-text("D:\XQuery\VPExchange Queires\diagramSelectionCoR.xq"), $bindings);
Instead, you applied $bindings to the file:read-text() function, which expects a string as a second parameter, thus BaseX tries to atomize the map to a string, which fails as you have seen.
Hope this helps Dirk

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:
