GridView paging inside a Multiview

Hi everyone,

I have a gridview inside a multiview. This is what happens, paging is enabled for my gridview but in an instance.
When I clicked page2, the activeviewindex resets to 0 instead of staying at its current viewindex and should be showing the records on the second page of my gridview.
What could possibly causes this?

Any help would be much appreciated, thanks.
