We recently upgraded a Tridion 2009 site to 2011, and are now trying to migrate the events code. Unfortunately Tridion doesn't seem to be hooking into the events.

I've done the following:

  • Update the event triggers in the MMC snap-in.
  • Deployed the events DLL to the 2011 server and registered it using regasm.exe.

Have I missed any steps out? I've written plenty of 2011 extensions but am not that familiar with how the 2009 events system works.

Legacy events are backwards compatible in Tridion 2011.

  • Check if you class is using this Prog Id "TDSEvents.Events"
  • Is your class COM visible?, you can check it in the AssemblyInfo class
  • Does your assembly have an strong name?

As Nuno always recommends, after you have checked all the steps above, create a single vbs file and try to create an object for your class.

Set obj = CreateObject("TDSEvents.Events")

If the object is not null, then your are good.

Hope this helps.

    Also, you may have to install the "LegacyEventAdapter" extension from Tridion world for events triggered by the Publisher service.

  • But in any case it is a lot better to just rewrite the code of your VB Event System and create a .Net one, the Legacy Event Adapter was just created to allow for quick upgrades when 2011 was just released, you should really consider not using it. Aug 15, 2013 at 7:50
