Classic Thesis Bibliography in child document

[Sergey Churilov]

Hi, 

I've noticed that if citing in child document, after compiling I get ?] symbol 
insted of proper reference.
If I compile from ClassicThesis.lyx everything is Ok and bibliography is listed 
in the end of the document es expected.
In order to compile only child document (e.g. single Chapter) with references 
do I need to insert Bibtex Bibliography... in each child document from 
Insert>List/TOC or there is some other way around?

Thanks,
Sergey
