In JSR-170 spec, for the XPath syntax : my:title IS NOT NULL => @my:title my:title IS NULL => not(@my:title)
On JackRabbit 2.0 beta 1 : //*...@property1 = 'some value' and not(path/to/my/@property2)] always returns no result, while : //*...@property1 = 'some value' and path/to/my/@property2] returns some results. Am I doing something wrong or it is a bug ? Frank
