[Gambas-user] XMLReader: strange message

[Toni Schornboeck]

Hello. 

I don't know wether it is a bug or a mistake by me. 

I get the following message in the "direktfenster"(I'm using the german 
version) (word by word translation: "direct window") 

WARNING: circular references detected
RootElement (1)
TextElement (5)
BlockElement (2)
EmptyElement (10)
WARNING: 74 allocation(s) non freed. 

RootElement, TextElement, BlockElement and EmptyElement are classes.
And the number is the amount of objects a created for each class. 

The code parses a XML file and does some evaluation (some kind of very 
trivial XSLT). 

The circular references are there, because every Element yields a reference 
to his parent.
I can't avoid this reference to parent and I see no reason to do so. 

What can I do about it? Obviously gambas does not free all elements, or does 
it even though this message? Is there something like a weak-reference or 
stuff like that to tell gambas that the reference to parent is just a 
pointer which doesn't own the pointee? 

thank you in advance
