[GeoNetwork-users] actions on selection

Hello,
In Geonetwork ver 2.6.4 options in "Actions on selection" window: "Display selected only" and Print to PDF" not working properly.
I saw in ticket #420 that these bugs would be corrected in ver 2.7.0.
Is it possible to add these improvements earlier in ver 2.6.5 ?
Users of our portal ( http://www.wodgik.katowice.pl:8080/geonetwork ) often tried to execute these options and I can't help them.
Or is it possible to change some files in ver 2.6.4 to make these options execute properly ?

Regards,
Piotr Pachół
