Hello Grégoire,
This error message is displayed when a nodeset is expected and when the
result of the expression evaluation is not returning a nodeset.
For example, confusing xf:output/@ref and xf:output/@value could produce
this error.
Could you please tell where this big XPath expression is used?
Thanks!
