Is this Commerce 7.5? Also, can you post some example code how you get this error? Thanks!

Hi,

Yes this is for 7.5. I have a catalog that currently has English and German, English is the default language for the catalog and during the catalog import the user can import German or English products. The following is the code we got the error with before,
--------------------
public ContentReference CreateOrUpdateNode(ContentReference parentReference, string name, string translatedName, IMarket market)
{
    var code = _catalogRepository.ConvertToCode(string.Format("{0} {1}", name.Trim(), parentReference.ID));
    var node = _catalogRepository.GetNode<Core.Models.MetaData.ProductNode>(code, market);
    if(node != null)
    {
        node = node.CreateWritableClone() as Core.Models.MetaData.ProductNode;
    }
    else
    {
        node = _contentRepository.GetDefault<Core.Models.MetaData.ProductNode>(parentReference, new LanguageSelector(market.DefaultLanguage);
        node.Name = _catalogRepository.GetSafeProductName(name);
       node.Code = code;
     }
     node.UrlSegment = Utilities.UrlUtility.GetSafeUrlSegment(translatedName);
     node.DisplayName = translatedName;
     return _contentRepository.Save(node, SaveAction.Publish, EPiServer.Security.AccessLevel.NoAccess);
}
--------------------
First we try to get the node, if it's not found get a default node for the current markets language (German) and then make the changes and save the node. If the node was null and the market is Germany we get the following error when trying to save it,
--------------------
The provided content link does not have a value.
Parameter name: contentLink
--------------------
Everything work perfect if we have already created the English version of the node and just add a new language version.
I have now rewritten the code as follows.
First get the current catalogs default language and find the language code for that language,
-------------------
var catalogReference = _referenceConverter.GetContentLink(Properties.Settings.Default.Import_Catalog_Id, CatalogContentType.Catalog, 0);
var catalog = _contentRepository.Get<CatalogContent>(catalogReference);
var defaultLanguageCode = _languageBranchRepository.ListAll()
    .Where(item => string.Compare(item.Name, catalog.DefaultLanguage, true) == 0)
    .Select(item => item.LanguageID)
    .FirstOrDefault();
-------------------
Then try to load the node for the current market (german) if it's not found create the node with the default language code, save it and try to load it again with the current market,
-------------------
public ContentReference CreateOrUpdateNode(ContentReference parentReference, string name, string translatedName, IMarket market, string defaultLanguageCode)
{
    var code = _catalogRepository.ConvertToCode(string.Format("{0} {1}", name.Trim(), parentReference.ID));
    var node = _catalogRepository.GetNode<Core.Models.MetaData.ProductNode>(code, market);
    if (node == null)
    {
        node = _contentRepository.GetDefault<Core.Models.MetaData.ProductNode>(parentReference, new LanguageSelector(defaultLanguageCode));
        node.Name = _catalogRepository.GetSafeProductName(name);
        node.Code = code;
        _contentRepository.Save(node, SaveAction.Publish, EPiServer.Security.AccessLevel.NoAccess);
        node = _catalogRepository.GetNode<Core.Models.MetaData.ProductNode>(code, market);
     }
     if (node != null)
     {
          node = node.CreateWritableClone() as Core.Models.MetaData.ProductNode;
          node.UrlSegment = Utilities.UrlUtility.GetSafeUrlSegment(translatedName);
          node.DisplayName = translatedName;
          return _contentRepository.Save(node, SaveAction.Publish, EPiServer.Security.AccessLevel.NoAccess);
     }
     return null;
}
-------------------
Both having to create the node like this and the way you have to find the default language code for the catalog feels unessesary "hard".

What if you do GetDefault without the language selector? I think it will give you the English one automatically. Then you'll have to save and publish the English version, load the German, Clone and edit it.

We are aware that the marriage of the CMS and the Catalog multi language features isn't perfect and we will try to improve it.
