Problem with case / else: in filters

Yep, that was a copy/paste error (I tool the example from the web site)
Actually I found a workaround for which I don't need an "else:" 
statement, and which is much better... !

Here was the faulty filter (of course replace example, XXX, prefix1 and 
prefix1 by valid info!)

filter in_asset_ASexample {
   if is_nexthop_false() then reject;
   case bgp_path.last {
     example: if ! (net ~ [ pref1+, pref2+ ]) then 
bgp_community.add((myas,XXX));
     else: bgp_community.add((myas,XXX));
   }
   accept;
}

Script returns:
bird: bird.conf.201012301556, line 169: syntax error
line 169 is the line with the else statement...

But if I reload the conf it seems to work...

Thanks,

Jerome
