We should look for CTT_Bad and see what is the appropriate error code for each (find the correct UA code and then add the CTT flag) [not just this instance]

Needs more information to better understand what could be done - can the exact script that is using this be included

The IsSubTypeOfType method does not necessarily talk to the server for this operation, it works on the object model cache that is created on a test run initialization.
Any errors encountered typically deal with a lack of information in the object model cache, usually from not having the ability to read the complete object model.
As such, having a 'Bad' error code is proper behaviour.

These errors, when encountered, are output to the trace window.

While testing a gateway we ran into this problem in many test scripts. Because the Gateway was configured with connections to several reference servers, the address space contained many nodes.
Perhaps it may be a good idea enhancing this functionality in a way that it automatically tries to browse/read the requested node if it is not part of the model map and if the server returns a valid response, also automatically updates the map.
Whether this is done best in the binaries or in the Helper needs to be discussed. I don't think, that we should do this in every test script that uses the offline map.
