>About what is better, all depends. Is there a big differences between information that both pages reuqired, if so I would prefer to use two instances and refresh/update only then when I needed. But If the information is similar (and not big) just get all information in one CA and then only filter it when you switch the pages.

I've decided to go with two separate BO classes and two separate CA classes too. The CA classes I've just finished creating, now I'm going to do the BO classes, then forms changes...
