Hi all, Urgent help required!!!! We have a requirement of opening a popup onselecting a checkbox. Iam able to open a visual force page from a visual force page after selecting check box. Both VF Pages are defined with extensions as same controller. When the pop up opens, the values in the controller are reset to null. How do i maintain session in between these two pages and use the values in the controller in the second page also. Thanks in Advance Nag
