Pagenumbers in index

[Robert Neumann]

Hello,
I'm using Lyx 1.20 and made a 2-sided document. Im using fancyhdr with the 
command \fancyfoot [LE,RO]{\thepage} for my pagenumbers

Now I'm adding an Index using the insert/index function of lyx.
The first side of the index-page (which is a right side) has the pagenumbers 
in the middle, the second as it should be on the left side.
Is there a way of solving this problem?
Thank you
Robert Neumann
