Problem with Session in IE, but not in Firefox and Chrome

[gpcontreras]

Friends,
I have a little big problem is that I'm creating a session variable at the time that the user is identified, this works fine.
When I create a new user (I use a windows component with a user control), I do it without problem and recharges my GridPanel. When
I edit a user's information, is published without problem, but my
GridPanel not recharge, said that the session variable is null. But
this only happens with Internet Explorer, I tried the same thing in
Firefox and Chrome and my GridPanel recharges without any problem.

You could help me, thanks.

    }
}

if I create a new employee and update an existing employee, the information is stored correctly. But
when employee information was updated saying that my session variable
is null (ArrayList alList = objectADO.GetEmployeeList (si.CompanyId);)
[NullReferenceException: Object reference not set to an instance of an object.]

But when the employee was created, the session variable is not null and load the list of employees in the GridPanel
