Please ignore my question: apparently I hadn't saved the module that corrected my bug. So sorry for the noise.

I have this recursive function that takes an array as its second parameter:

declare function lmm:applyScopesToNames( $keyNames as xs:string+, $keyScopes as array(*), $qualifiedNames as xs:string*) as xs:string* { let $result := if (array:size($keyScopes) = 0) then $qualifiedNames else let $newNames := for $name in $keyNames return for $scopeName in $keyScopes(1) return $scopeName || "." || $name return lmm:applyScopesToNames( $newNames, array:tail($keyScopes), ($qualifiedNames, $newNames) ) return $result };

Testing with this input:

let $keyName := "base" $keyScopes := [("s3", "s4"), ("s1", "s2")]

This call:

let $qualifiedNames := lmm:applyScopesToNames( ($keyName), $keyScopes, ())

Results in the message "Item expected, sequence found: [("s3", "s4"), ("s1", "s2")]."

Unfortunately, the BaseX interactive query tool doesn't report the line that produces the message, but the only place I'm passing the full array is in the initial call to the function from my test query.

I've also verified that if I pass in [] as the keyScopes parameter then I get the expected result (that is, the value of the 3rd parameter is returned).

I've verified that $keyScopes is an array of two sequences and as far as I can tell I'm passing arrays where arrays are expected so I'm not sure what my error is, but there must be one.

Thanks,

Eliot
