display tag and struts

[Otto, Frank]

Hello,
 
I have read something about diplay tag library and have test it. If I want to sort the 
table by clicking on column, I will get an error, because my collection is null. It 
isn't saved in the session, only in the request. An idea?
 
My other questions is:
 
- Can I use display tag with i18n and resource bundles? I need the column titles in 
different languages.
 
 
Regards,
 
Frank
