Getting consistency in MDG "Types"

[Paolo F Cantoni]

We created a repository and added thousands of objects.   We LATER created an MDG technology and continued to add objects.

Now, in the Model Search window, when we do a search for objects we get inconsistent results in the Type column.  Suppose stereotype "S1" is a stereotype NOW associated with MDG technology T1.  The name of the type thus created in T1 is (say) T1_S1.  Some objects in the Model search window have Type = T1_S1 and stereotype = S1 and others have Type = Class and stereotype = S1 - as far as we can tell these are the objects created before the T1 MDGT was created and used in the toolbox.
ALL objects have been "FIXED" to ensure the t_xref stereotype entries have the value associated with the MDG T1 (that is, they have an FQName entry that references T1::S1) and consequently will ALL show T1_S1 in the Type slot of properties window for the object.
If one accesses the properties of a non-T1_S1 object and saves it, the Model Search Type changes from Class to T1_S1 - however this DOES NOT persist across EA invocations.

So what I want to know is where is the "secret sauce" that will make all my objects show T1_S1 in the Model Search Type (or is it just another EAUI bug - among SOOOO many).

We have literally thousands of pobjects to fix and manually is not an option.

TIA,
Paolo
