primefaces version: 2.2 M1
server: glassfish v3

I am having a problem using paginator, sortBy, filterBy when using anything but a SessionScoped backing bean. If I change the bean below from @ConversationScoped to @SessionScoped everything works wonderfully

is this a known issue? or possibly because this is not working in 2.2 M1 (I am going to test out 2.1 soon) I see that this is a brand new datatable in 2.2

I am seeing the same thing in 2.1 when using dynamic="true"

my problem sounds similar to http://primefaces.prime.com.tr/forum/vi ... f=3&t=1271 but that post said it was working in 2.1

ok so I tried changing

Code: Select all

@Named("ListBean")
@ConversationScoped
to

Code: Select all

@ManagedBean(name="ListBean")
@ViewScoped
and that works in 2.1 (neither work in 2.2)

let me know if there is anything you need me to test, but it sounds like this is a known issue

2.2's datatable is brand new and still under development, the labs example are based on @ViewScoped and seem to run fine though.
