Operation Map throws class not found error after switching to use DAE adapters.

I have an interface that was working fine on our dev Central Adapter Engine ... I then switch the communication channels to use the dev DAE (distributed adapter engine) and now I get an error about a message map class not found ... here is the error.

I have performed the following without any improvement:

* requested a full cache reset

* rebooted both PI servers (internal server and externally facing runtime server)

* rebuilt the Integrated Configuration from scratch.

* changed the name of the message map (via new copy) to not include the word XML (just a thought) so I changed it to addNodeTag instead of addXMLTag.

* FYI - translation of the German in the message: could not be found in the following software component versions: b5ed0aa0-f42e-11e2-9793-efdd0ae83140

As far as I know I am not required to move anything to the DAE server as it should be all automatic. It obviously sees my new message map without doing any special procedure. What am I missing? Note, this is my first attempt at adding a DAE interface.

Should I rebuild the message map from scratch? Could it be corrupt? Tips on debugging this? Many thanks for your help.
