Session State in Back Office

[trozzi]

We are testing for a client that will be deploying in a web farm. We configured Sql Session State to manage the web site. Everything test fine on the site. We navigated to the following page in he back office

/Admin/Products/Reviews/Default.aspx

We raised the following error

Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.

Thanks

We configured Sql Session State to manage the web site.

Not sure what this means. Can you please explain?

Please give a try to this solution. Edit the App_Code/SearchCriteriaCache.cs file
and locate the following class

Code: Select all

 public class SearchCriteria
    {
        public Dictionary<string, object> Arguments;
        public int PageIndex;
        public string SortExpression;
        public SortDirection SortDirection;

        public SearchCriteria()
        {
            Arguments = new Dictionary<string, object>();
            PageIndex = 0;
            SortExpression = string.Empty;
            SortDirection = SortDirection.Ascending;
        }
    }

and mark this class as serializeable by putting an attribute upon it as below

Code: Select all

[Serializable]
 public class SearchCriteria
    {
        public Dictionary<string, object> Arguments;
        public int PageIndex;
        public string SortExpression;
        public SortDirection SortDirection;

        public SearchCriteria()
        {
            Arguments = new Dictionary<string, object>();
            PageIndex = 0;
            SortExpression = string.Empty;
            SortDirection = SortDirection.Ascending;
        }
    }

Thanks AbleCommerce Developers

Found a new page that has the same error message.

It appears to be from the line of code.
OrderSearchCriteria criteria = Session["OrderSearchCriteria"] as OrderSearchCriteria;

I think this object needs tagged as Serializable, but it is contained in one of Able Commerce's assemblies.

/Admin/Orders/Default.aspx

Thanks

This time the solution is not simple.
The object that needs to be Serializable in this case is in the compiled DLL.
It is CommerceBuilder.Reporting.OrderSearchCriteria.
A DLL update would be needed to get this fixed.
I have escalated this case in our bug tracking system. We will see if a patch could be provided for this.

Another Page

/Admin/Website/Scriptlets/ConLibHelp2.aspx

I greped the admin area for "Session[" and I found these others that look like they may be in the same category...
ConLibHelp.aspx.cs
ConLibHelp2.aspx.cs
ConLibHelpAll.aspx.cs

Thanks

Yes we have identified the above as well as ConLib/SimilarProducts.ascx.cs as potential candidates for such errors.

I have a client that just upgraded to 7.03 and is still getting this message. According to bug 7075, this should have been fixed in 7.0. I have pasted the exact error we are getting below. The error occurs when attempting to access the Manage/Users screen.

Server Error in '/' Application.

Can someone at Able take a look at this error, please?

[Logan Rhodehamel]

Bug 8148.. same error message, different code problem.

http://help.ablecommerce.com/upgrades/a ... _7.0.3.htm

It should be corrected by the latest CommerceBuilder.DLL. Please let me know if not.
