Wierd session state error

[Cirene]

In my web.config I added <pages enableSessionSt ate="true">.

In each of my pages I also added EnableSessionSt ate="True" to the Page
declaration.

(I didn't think this was necessary, but...)

Any reason why even though I did this I keep getting this error....

Is this the extent of your session state tag?
<pages enableSessionSt ate="true">

If so, that is your problem. You have to specify what type of state (most
likely inProc here) and potentially set a few other values as well. Here is
an example of using SQL Server:

<sessionState
mode="SQLServer "
sqlConnectionSt ring="data source=db1;user
id=db1User;pass word=password"
cookieless="fal se"
timeout="20"
/>

Instead of using a shoppingcart object in Session, have you tested with a

It works fine with a simple string. So the problem must be with storing the
object in Session. Any ideas why I can't do this?

the abcshoppingcart is basically defined as this...

Public Class abcshoppingcart
Public Customer as new abccustomer
Public Product as List(of abcproduct)
End Class

Any ideas? Thanks!

I think you problem is in this code (Line 5).

Line 3: Inherits System.Web.UI.P age
Line 4:
Line 5: Dim c As abcshoppingcart = Session("Cart")
Line 6:
Line 7: Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArg s) Handles Me.Load
Question to you: When do you think Line 5 is executed. Answer "no clue" is
bad answer.

When you page (or any object) is created .NET runtime follows following
steps
1. Memory allocated for the object.
2. Memory is initialized according to the defaults or what you wrote (like
you did in line 5). so if you declared member variable Int it's initialized
with 0 unless you wrote Dim k as Int = 4
Then it's initialized with 4.
3. Constructor called.

Only after that object is 'declared' created and we or ASP.NET might start
working with it. IE assign member variables like Session, Page, Request,
Response...

The method PreInit called, then Init.....

so if you want to access Session object you must do it much later... Like in
Page_Load event for example.
