default element namespace and restxq - BaseX-Talk - mailman.uni-konstanz.de

27 Nov 2013


      Hi,
I'm experiencing problems using a default element namespace in a  
restxq module. Here is a working example taken from the default restxq  
module. All I addded is the namespace of the response element.
module namespace page = 'http://basex.org/modules/web-page';
declare namespace test = 'http://test-namespace.org';
declare
%rest:path("/ajax/hello/{$world}")
%rest:GET
function page:hello($world as xs:string) as element(test:response) {
   test:response
     test:titleHello { $world }!</test:title>
     test:timeThe current time is: { current-time() }</test:time>
   </test:response>
};
If I now introduce a default element namespace just to simplify  
notation, I get a NullPointerException
module namespace page = 'http://basex.org/modules/web-page';
declare default element namespace 'http://test-namespace.org';
declare
%rest:path("/ajax/hello/{$world}")
%rest:GET
function page:hello($world as xs:string) as element(response) {
   <response>
     <title>Hello { $world }!</title>
     <time>The current time is: { current-time() }</time>
   </response>
};
java.lang.NullPointerException
