Boolean function true() in query string

[MARTINEZ Antonio]

Hello,

And according to the JSR170 document, it should work since the Boolean
function true() should just be a true expression.

Using this query returns all my "pon" objects 
  //Inventory//ne/rack/subrack/slot/pon

But using 
   //Inventory//ne/rack/subrack/slot/pon[true()]
 
I get error  
   "java.lang.RuntimeException: Query failed: Unsupported location for
true()"


Is there an error in my query string or is it not supported ?

Thanks,
Antonio
