Hello, I’m a new Saxon user and I need some help. My question is about the Xquery call from a Java application. (you will find at the end of this mail the code corresponding to my question). I don’t understand why the “testMethod” of my TestClass is called two times. This behavior seems to appear only if a no empty list is returned (If my method returns an empty list or returns a simple String, the testMethod is called only one time). When I follow the execution, I can see that the ExtensionFunctionCall.call is called two times. If somebody can test this code … Thanks, Best regards.
