Re: [gate-users] Syntax tree view and logic form on SUPPLE

[Mark A. G. <ma...@dc...>]

Hi,
	The only reason it would return null is if there aren't any annotations 
of type "semantics" in the set (for some strange reason it returns null 
in this situation rather than an empty AnnotationSet).

What I don't understand is why there should be no annotations of type 
"semantics". When you print out just doc.getAnnotations() can you see 
the semantics annotations in among everything else? What happens if you 
try to get the "parse" annotations instead does this work or does this 
also fail?

If both fail it suggests that the parse isn't working properly, are 
there any error messages appearing?
