Hi Paul!!!! Thanks for your answers, yes actually when I implemented your filter the call to the DB reduce to 2 :), and then Vladimir says that with the backing_bean in session all works fine, and yes, all works fine :), the only problem is that when I implemented the add, delete, and the edit actions the data in the data scroller is not update until I click on any page link of the table (1,2,3). I think that this happen because of the filter (if) that you did (great) so what I need now is a way to do the fetch no matter what after and add/delete/edit action is made. So I was thinking in add another condition to the if(.... || (doNomatherWhat) ...doFech). What I dont know is where define this variable, and where to assign it the value to true after the add/delete/edit method was called. Can you help me on this?
I think Vladimir write ideas about this I'm going to read then, and I will wait for yours too thank you and thanks Vladimir!!! On 7/5/07, Paul Iov <[EMAIL PROTECTED]> wrote:
