ok I found a way to do this, but I'm not sure if that's the right
approach.
What I'm doing now, is store the incoming filter-options in the
Session. When a user comes into the controller for the first time, I
check if the session-keys are set, and if not, I apply some standard
options. When the user sends the form, I write the selections into the
session, and then set my variables with these session values. This
works perfectly, even when I'm on page 2 and use the column-sorting
everything is displayed correctly.
I don't know if this is absolutely correct, but it works and I'll
further develop this if anyone can tell me a better way to do this...
Regards,
DD
