Pagination problem when user is logged in

Hello,

I have a problem with table jx, when user is logged in. I have a grid in an article restricted to an specific user group, so when a user who belongs to this group logs in and get access to this article everything runs fine, but just the first time, if the user advances to second page then he gets automatically logged off as he is redirected to login page. This error also happens when user tries to refresh the page.

This problem disappears when pagination is disabled in the grid, then everything goes as it should run. After some tests I found out that the error only happens when the user is logged in and an article or menu item is restricted to a group different than public. I haven't seen this bug to occur when there's no restriction in the access level, it's when the article or menu item is set to public access.

Can you help with this matter or suggest any workaround?

Thanks in advance

Thanks for your answer. I am using table jx, version 2.5.6.
