Webstore: Product Paging Error

Hi Joe,

I was setting the new paging feature of Webstore released with version 2.3.4.1 and when I set a "Product List Page Size" value lower than the actual number of products in my store, the server gave me back the following error:

Re: Webstore: Product Paging Error

Hi Diego,

I do not get this error on my local machine, perhaps it requires some specific conditions or product/offer settings.

Can you try to produce the error on demo.mojoportal.com? Then I could get clues to the conditions that cause the problem.

Thanks,

Joe

Re: Webstore: Product Paging Error

Hi Joe,

I have just completed the test on your demo site.

I have reproduced a simplified structure of my store: http://www.effectiveweb.it/web-store.aspx

  • 3 products (in my store they are 7)
  • Multiple offers for each one (in my store they are 1 to 6)

Then I set the page max to 2 products per page and everything works fine. I could not reproduce the error I get on my site when the number of products in list is higher of the page size value.

Re: Webstore: Product Paging Error

Hi Joe, Hi Diego,

Win 2008 web server
MySQL
2.3.4.1

On my sites the same problem. On demonstration a site to play back a problem it is impossible, but the demo a site uses base MSSQL, and my sites work with base MySQL. The Reason in it can? I have checked up some sites, the problem is...

Specification
On a new site, (with MySQL), which it was developed at once from the version 2341 and in which the new store was created, the problem has not repeated. Probably problem not in MySQL.

Re: Webstore: Product Paging Error

My environment is:

Server: IIS 7 + MS SQL Server 2008

Client: Windows 7 + IE8
 

According to what Stas said, it seems not depending form the database platform (his MySQL and my MSSQL had the same problem). Stas' new site built fom V2.3.4.1 seams not affected, but we both faced the problem on upgraded sites.

My site was upgraded from previous version 2.3.3.9

Re: Webstore: Product Paging Error

I have found the reason and have played back a situation on a site demo.mojoportal.com. Problems arise, at change of values in fields "Primary Sort Rank" and "Secondary Sort Rank"

Re: Webstore: Product Paging Error

Hi Stas,

Good work in finding the steps to produce the problem. I have fixed it in my copy and the fix will be in svn trunk by late tonight.

I sent Diego a script to alter a stored procedure which will fix it immediately for MS SQL. Unfortunately since the MySql sql statments are embedded in the WebStore.Data.dll, it will be fixed in the next release, I can't provide a script to fix it.

I will try to get a bug fix release out soon.

Thanks,

Joe
