Firstly, this is an 8.5 instance, upgraded from 2013, upgraded from 2011. We have Audience Manager installed (and working well) and outbound email.

I have a set of custom events that subscribe (when the services are started) and execute (when publishing) as expected.

We are, however, unable to use Template Builder as it fails on initialization - stating errors with the same event code.

I've confirmed the custom DLL is the same version in

  • \SDL Web\bin (as configured in tridion.contentmanager.config)
  • \SDL Web\templates\bin (not 100% certain it needs to be there likely clean later)
  • \SDL Web\webservices\bin (not 100% certain it needs to be there likely clean later)

I've tried this with a PT with no TBBs attached. CPs/Pages Preview and Publish.

The error (below) only shows the first time I run Template Builder, following that the default TCM Event DLL then fails - consistently. If I restart Template Builder App - back to the first error.

I'm seeing nothing in the logs (other than the error noted above from the Event Logs).

I've increased logging on Template Builder but nothing - this only logs once a certain point of initialization has been hit.

I've confirmed the Services are running as expected

  • Publisher with Local User (permissions to read on assembly)
  • Service Host with NETWORK SERVICES (permissions to read on assembly)

I checked with ProcMon and confirmed no ACCESS DENIED for Tcm activities.

  • Can you try changing or add the order (to the question) in which your Custom event is being executed from your Tridion.ContentManager.config? I have noticed that there are a few changes in the way certain events are initialized with 8.5. – Shiva Dec 6 at 16:24

If you run/debug a Template in Template Builder, it will be executed on the CM Server in a process called TcmTemplateDebugHost. This process hosts the entire CM Kernel, including all configured extensions.

You can attach a (remote) debugger to this process to debug your .NET Template code, but also your custom extensions.

So: I would recommend to attach a debugger toTcmTemplateDebugHost and set it to break on all exceptions. Then try to run/debug a template and see if the debugger breaks in your custom extension.

In the application, there is also RedSharp. It seems that, although the version of **Log4Net* in the app and used by RedSharp is the same - there's some odd conflict and rather than falling over on one - the application simply stops.

Removing Log4Net from the application (and not touching the RedSharp instance) allows Template Builder to load and work. Not a long-term solution I accept but workable for now.

I'm hoping the client digs deeper to resolve and I can update this post with more information on the root cause/fix.
