Pipeline Editor displays registered custom pipeline components as unknown in 64 Bit version.

ravikanth | August 26, 2010

If you are using commerce server 2007/2009 on 64 bit machine and used pipeline component registration wizard to register pipeline components and if we try to open 64 bit pipeline editor, you may not see your component rather you will see "<<unknown>>” message. This issue occurs because Pipereg.exe cannot recognize 64-bit architecture. To resolve this issue, follow below steps.

  • Use the 64-bit version of the Assembly Registration tool (Regasm.exe) to prepare the custom pipeline components for registration(C:\Windows\Microsoft.NET\Framework64\v2.0.50727). So, open Open a command prompt, Change default installation folder for the .NET Framework and run below command.
    regasm MyAssemblyComp.dll /tlb:MyAssemblyComp.tlb 
  • Use Pipereg.exe to register the type library file that you created in above step. Make sure that you select the Export registration data option to export the registry information to a .reg file. 
  • At a command prompt, run the .reg file that you created above or run the .reg file directly from Windows Explorer.

If you check, the custom pipeline components appear correctly in the 64-bit version of Pipeline Editor. 

Optional: If you still have the issue then you can use Microsoft regcleaner tool to clean the unnecessary registry entries from the system and perform above steps again. Warning Serious problems might occur if you opt this method and you reinstall the operating system. No one (including Microsoft) cannot guarantee that these problems can be solved. So, modify the registry at your own risk.

Failed to set value for profile property ‘email_address’.

ravikanth | June 15, 2010

For past few days, the below exception has taken away my sleep. This error occurs in our pre-prod environment and it is totally unpredictable. You may get or may not get with the same data. Profile registration is first page to any ecommerce application and as it is failing here and as usual everyone swords are towards me for the fix.

An exception of type ‘Microsoft.CommerceServer.Runtime.Profiles.CommerceProfileSystemException’ occurred and was caught.

Since the error is happening in translator, I suspect that I am passing wrong data to the commerce server. I verified that user_id (guid) and email address are sent from controller class. I google or binged but no luck.

Missile trigger happens at one place and damage at another place. This problem comes under same category. Everybody sees this as commerce server exception as below error found in event log with lot of “commerce” words. After lot of efforts, I found that the error is due to assigning to wrong GUID and email_ID. For example, consider following data.

user_ID email ID
Guid1 user1@test.com
Guid2 user2@test.com

First I sign-in with user 1 and both user_id and email_id are stored in cookie. I press sign-out email_id is removed from cookie but not user_id. The second time, I logged in with user2 now this time, the user 2 email_id is keep in cookie but  its GUID is not updated (as the old object already exist in the cookie). When I try to save user profile, I am passing GUID1 and user2@test.com to commerce server and it is throwing exception as the update operation tries to update row 1 with user2@test.com in email_id field (which is a unique key).

ArgumentException: An item with the same key has already been added.

ravikanth | June 12, 2010

After successful application deployment in pre-production environment and when I ran the application start page, I got below exception. We shouted “Not Again”… setting up of CS2009 application is not a simple task and automating the installation is a nightmare (as usual, we doubted our installation tool for not installing the application correctly). The exception is wired and we are not able to figure out why the error has occurred?

An exception of type ‘System.ArgumentException’ occurred and was caught.

CS2009 exceptions are not user friendly. You need more troubleshooting skills to see what is the problem and where exactly to tweak to make the application work. Since our site is running on variations (to support multiple languages), I had make sure that our site channel configuration is pointed to correct values. 

To troubleshoot these kind of errors, I suggest every CS2009 developer to download Reflector tool. This tool will help us see how the assembly code has written and what values it is expecting and on which condition it is throwing certain exception. After troubleshooting further, I came to know that the old site is not deleted which is currently pointing to same commerce server site and running in same application pool. After stopping the old site, my site started working. Seems CS2009 is adding the site name to a dictionary and it is throwing “An item with the same key has already been added.“exception as the site name was already entered by the first site into the dictionary.

Error: Microsoft.Commerce.Contracts.Faults.ItemDoesNotExistFault

ravikanth | June 5, 2010

On saving customer profile and performing the update, I am getting wired error (as shown in below table).

Type : System.ServiceModel.FaultException`1[[Microsoft.Commerce.Contracts.Faults.ItemDoesNotExistFault, Microsoft.Commerce.Contracts, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]], System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

Reason : The requested item does not exist.

Stack Trace : at Microsoft.Commerce.Providers.Components.ProfileOperationSequenceComponent.GetMatches
CommerceModelSearch searchCriteria, Nullable`1& totalItemCount, Boolean throwIfNotFound)

Apart from this error, nothing is written in event log. Running SQL trace also didn’t help as I haven’t seen entries coming there. Using reflector, when I go through the assembly, I found on interesting thing (check below image).

Commerce server while retrieving values, checks if their are any values in the key property, if not found it will throw item not found exception. Later I figured out that in my code, I am passing wrong user ID to commerce server, thus triggering this error.

Troubleshoot: Configuration specifies useSharedCommerceContexts=true. Contexts cannot be requested for other Commerce Server sites.

ravikanth | May 14, 2010

Today, I got latest code from TFS and setup my application. When I execute the application I got wired error.

An exception of type ‘Microsoft.Commerce.Providers.Exceptions.ContextCreationException’ occurred and was caught.

I have only one commerce server site configured in my application and from frontend configuration, I can’t connect to another commerce server in different machine (currently CS and MOSS are hug and can’t work from different machines). After troubleshooting further, I found that it is due to the case sensitive of site name in channelconfiguration file. The CS site created on my desktop is “SiteName” and the site name in channel configuration file is “Sitename”. After changing the site name, the application started working fine.

Even though the fix is simple but would like to keep it in my blog so that fellow developers (like me) will not waste their time much in fixing this simple issue.
