Hello,

After configuring my meta class (changing, adding and deleting attributes) every category page or product page gives me the "Critical Error [DataClientException]"

Here's the message from a product page :

System.NullReferenceException: Object reference not set to an instance of an object. at Mediachase.MetaDataPlus.MetaObject.GetElementaryFieldValues() at Mediachase.eCF.BusFacade.Filters.Products.MetaAttributesContentFilter.GetProductMetaFields(Product product) at Mediachase.eCF.BusFacade.Filters.Products.MetaAttributesContentFilter.CreateItem(Item& item, IMetaObject metaObject, String[] responseGroup, IList`1& errorArray) at Mediachase.eCF.BusFacade.ContentFilters.PopulateProductItem(Item& productItem, Product product, String currencyCode, String[] responseGroup, IList`1& errorArray) at Mediachase.eCF.BusFacade.SiteManager.ProcessSiteLookupRequest(SiteLookupRequest request, IList`1& errorArray) at Mediachase.eCF.BusFacade.SiteManager.SiteLookup(SiteLookup lookup) at Mediachase.eCF.ClientLib2.ClientProduct.LookupProducts(SiteLookupRequestIdType type, Int32[] objects, String[] responseGroups, ErrorsError[]& errors)

Is there anything i can do ? Or where to look at ?

Thanks,
Victor

What version of ECF are you using? Have you made any changes to the database?

Trial version. No modifications made to the db.

What is the exact version? (4.1.x)

4.1.2

We couldn't replicate the error on our computers. Can you describe the steps that lead to the error? Also, check up that Mediachase.eCommerce.MetaDataPlus.dll version is 1.6.2986.33229

Yes, is the same version.

I think the problem is with some Meta attribute which was set not to allow nulls but it has null values. Anyway, if i export the products and the master template with the metadata and i import them on another instance, they seem to work perfectly.

But doing that i've noticed a new problem. The meta values for the Multiple-entry dictionary attributes were not exported. Is there any way to get them ?

Hi,

   Problem with Meta Dictionary values is solved and can be available with full source code license.

And there's no option for the production license ?

   Here's the dll that has changed. Replace the corresponding dll in your Bin folder with the attached one. Don't forget to back up your current dll.

What did change ? Because still doesn't export all the values...

Have you restarted IIS after replacing dll?

Sorry to reply so late, but i've managed to fix the problem by re-importing the entire catalog.

However, a similar error appears when i perform a search on the front :

System.NullReferenceException: Object reference not set to an instance of an object. at Mediachase.MetaDataPlus.MetaObject.GetElementaryFieldValues() at Mediachase.eCF.BusFacade.Filters.Products.MetaAttributesContentFilter.GetProductMetaFields(Product product) at Mediachase.eCF.BusFacade.Filters.Products.MetaAttributesContentFilter.CreateItem(Item& item, IMetaObject metaObject, String[] responseGroup, IList`1& errorArray) at Mediachase.eCF.BusFacade.ContentFilters.PopulateProductItem(Item& productItem, Product product, String currencyCode, String[] responseGroup, IList`1& errorArray) at Mediachase.eCF.BusFacade.Filters.Products.ProductSearchContentFilter.CreateProductItemsBySearch(SiteSearchRequest request, IList`1& errorArray) at Mediachase.eCF.BusFacade.ContentFilters.PopulateProductSearchItem(SiteSearchRequest request, IList`1& errorArray) at Mediachase.eCF.BusFacade.SiteManager.SiteSearch(SiteSearch search) at Mediachase.eCF.ClientLib2.ClientCatalog.SearchProducts(String searchIndex, String keywords, String[] searchFields, KeyValueAttribute[] filter, Int32 categoryid, Boolean incSubCategoryNodes, Decimal minprice, Decimal maxprice, String sort, Boolean sortOrder, String wherest, Int32 itemsPerPage, Int32 currentPage, String[] responseGroup, Int32& totalRecords, ErrorsError[]& errors)

The problem appears only if i search against all products. When i select a specific Attribute class it works.

It seems the problem is with one of the Meta Classes. When i select any other class, it works.
Maybe it has something to do with a Meta Field that is null and it was not supposed to be null ?

Hi,
it is hard to say where the problem is without your database. Please export your MetaData configuration to .ecf file (Master Templates List\Export to .ecf) and send us your database and the file to support@mediachase.com.
