Hi, In a function resembling declare function local:foo($es as java-type:net.sf.saxon.functions.Evaluate-PreparedExpression+) { myclass:bar($es) } where myclass's bar method looks liks: public static SequenceIterator bar(Evaluate.PreparedExpression[] es) { ... } I get an error converting the argument IF a sequence of length 1 is passed to local:foo: Error in call to extension function ... Conversion of external object to [Lnet.sf.saxon.functions.Evaluate$PreparedExpression; is not supported As long as the sequence is not a singleton the conversion succeeds. I can work around it by having local:foo always add a dummy expression to the sequence and the java method ignore it. http://saxonica.com/documentation/extensibility/converting-args/converting-atomic.html seems to say that conversion to an array should be possible as long as the static type of $es allows a sequence of more than one item (which it does, as it's declared with +). So, should this not work even when $es happens dynamically to be a singleton? The particular app where I'm doing this is still on bj 8.0, if that matters. -Chap
