I have a custom class written "GetTcmUriFromWebDav" which inherits TBBFrameworkBuildingBlock. When trying to use this class in a component, it throws an error and it fails to initialize assembly and searches for some reference. The Same works in Tridion 2011 but fails in Web 8.5

public class GetTcmUriFromWebDav : TBBFrameworkBuildingBlock
    {
        public override void ExecuteTransform(ITBBFrameworkContext tbbContext)
        {
           // tbbContext.LogDebug("Testing ITG-Getting into GetTcmUriFromWebDav ");
            tbbContext.LogDebug("Processing [{0}] parameters to retrieve TcmUri values for:", tbbContext.QueryString.Count);
            foreach (String variableKey in tbbContext.QueryString.AllKeys)
            {
                Stopwatch timer = new Stopwatch();

                if (!variableKey.IsNullOrEmpty())
                {
                    //Retrieve the Value for the current Key
                    String itemWebDavOrTcmUri = tbbContext[variableKey];

                    if (!itemWebDavOrTcmUri.IsNullOrEmpty())
                    {
                        //Output detailed information that is being processed if Enhanced Debug output is enabled.
                        tbbContext.LogDebug(" - Package Variable Name: {0}", variableKey);
                        tbbContext.LogDebug(" - WebDav Url: {0}", itemWebDavOrTcmUri);

                        //Ensure the benchmark timer is running and reset for the current retrieval.
                        timer.Restart();

                        string pubwedav = tbbContext.GetContextPublication().WebDavUrl.ToString();
                        itemWebDavOrTcmUri = pubwedav + itemWebDavOrTcmUri;
                        //Retrieve the TcmUri of the Tridion Item
                        var tridionItem = tbbContext.RetrieveItemAsObject(itemWebDavOrTcmUri);
                        TcmUri tcmUri = tridionItem != null ? tridionItem.Id : null;

                        //Output detailed benchmarch retrival time for performance testing
                        tbbContext.LogDebug(" - Tridion Retrival Time: [{0}] seconds", timer.Elapsed.TotalSeconds);

                        //Now push the Final value into the Package
                        String strTcmUri = tcmUri.ToString();
                        tbbContext.PushTextDataIntoPackage(variableKey, strTcmUri);
                        tbbContext.LogDebug(" - Added variable to Package:  {0} == {1}", variableKey, strTcmUri);
                    }
                    else
                    {
                        tbbContext.LogDebug(" - Unable to add variable to Package; Zero length WebDav parameters are not allowed:  {0}", tbbContext.GetQueryStringFullString());
                    }
                }
                else
                {
                    tbbContext.LogDebug(" - Unable to add variable to Package; Zero length variable names are not allowed:  {0}", tbbContext.GetQueryStringFullString());
                }
            }

        }

  • TBBFrameworkBuildingBlock seems to be some custom developed class, which you are inheriting from. There's not much we can do to help you here. It might be useful to clearly specify which error you get, instead of mentioning there is "some" error. Can you put the full error message/stack trace you see when the problem occurs?

You are doing an upgrade from 2013 to 8.5 so that means that all your custom assemblies must also be upgraded. What it means is that they (in their implementation reference 2013 dlls.) So you need to update each of those to use 8.5 dlls, and reupload them in Tridion.TBBFrameworkBuildingBlock is an example of custom assembly your team created. :D

From the error message/stack trace you posted, it looks like this assembly is missing

Could not load file or assembly 'HP.Common,...

This means that a dll HP.Common can not be found on the CM server where you are trying to run the TBB code.

Most likely, this dll should be added to the GAC. Can you check if you can locate this dll in the 2013 environment you are upgrading from?

  • Thank you for the suggestion. I tried adding the dll in GAC, it gives the below error " Failure adding assembly to the cache: This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. "

  • see if this helps stackoverflow.com/questions/57189959/…. Note : are you using gacutil (a visual studio tool) to add this to the GAC? This is ok for dev purposes, but doesn't work well on a production environment. Try doing this via powershell (see andrewcbancroft.com/2015/12/16/…) instead
