[Qexo-general] Qexo and index-of

[David Mundie]

I can't get index-of to work. It's not marked as CVS-only, but when I 
run the following query

let $birds := document("test.xml")/checklist//bird/sci
return index-of(string($birds), "Casu")

I get this error message:

        at gnu.mapping.Binding.get(Binding.java:25)

What am I missing? Here is test.xml:
