Does the layer have a TEMPLATE "dummy" or some real template?

Here is simple query only layer definition I use. I have not tried this 
on 4.2 yet:

   LAYER
     NAME "states"
     TYPE QUERY
     STATUS ON
     DATA "us/st99_d00"
     TOLERANCE 50
     TOLERANCEUNITS FEET
     CLASS
       TEMPLATE "dummy"
     END
     METADATA
       "DESCRIPTION"    "States"
       "RESULT_FIELDS"  "NAME"
     END
   END
