Thanks for the reply but I am afraid it's not what I need to achieve. 
I've already managed to define static hierarchy by defining hierarchical 
field, adding it to used document type and querying by that field value. 
The problem is that I'd like to be able to create (modify) hierarchy 
without changing static field hierarchy definition... So users of my CMS 
could just add new document, choose parent document from a listbox and 
see it in the navigational tree... That's why I was trying to make link 
field hierarchical and query by this field ...

I hope I've managed to make myself clear enough... Do you see it 
possible in the current Daisy version?

Thanks for assistance,

Wojtek
