fo:change-bar problem with AT format

 
 
Good morning,
I would like to report the following problem.

Add fo:change-bar on any fo file and make PDF with fop: it work well. Then make AT format with the same fo file and then make PDF from the generated AT file: output is wrong (change bar and text are overlapped and moved)

Regards

Used commands:

• PDF (work well): fop testChangeBar.fo -pdf ok.pdf
• AT + PDF (wrong): fop testChangeBar.fo -at test.at
  and then
  fop -atin test.at -pdf wrong.pdf
