Hi Sebastian, The following query should work fine (at least with the latest snapshot; I haven’t tried 8.4.3): let $f := function-lookup(xs:QName('db:replace'), 3) return updating $f('db', 'x.xml', <a/>) Did you specify the "updating" keyword [1]? Could you give us a little example?

Hi everyone!

I stumbled over a problem after upgrading BaseX from version 8.4 to 8.4.3. : db:replace does not work (no error message), when used in a function-lookup.

Has anyone made a similar observation? Is there any other way to add a document to a collection? XQuery update still works.

Best regards, Sebastian
