Saxon 8.1.1 declareVariable problem

    newby here so sorry if this is an obvious mistake. I need to declare a variable that my query uses. I have the following code:

    final Configuration config;
    DynamicQueryContext dynamicContext ;
    StaticQueryContext staticContext;
    //some instantiation here

    new DOMSource(dom)) );

    String query="for $a in $root//price return $a";

    Variable thisVar = Variable.make("root");
    thisVar.setValue(dynamicContext.getContextNode() );


    XQueryExpression exp = staticContext.compileQuery(query);

    At which point I get a runtime exception that variable $root is not declared (I know the query is unnecessarily complex but for purposes of my app I prefer not to alter the query). The binding I'm trying to achieve is equivalent to let $root:=doc(...).

    Also, through some debugging, I know the binding makes into the variables map of the static context object...not sure why it's not found when compile is called.

    Thanks for any help

      Your query needs to declare the variable $root as an external variable:

      declare variable $root external;
