[omniORB] Problem passing an array of structs

[W T Meyer]

I'm trying to pass a fixed-length array of structs and I'm getting a 
cryptic error message.  I see others have posted similar - but not 
identical - problems and it is not clear to me what the solution or 
workaround is. Can someone provide some insight?

Here is my IDL:
------------
module CoRCC {

    enum vmeType {SBC, ROD, TIM, EMPTY, OTHER, UNKNOWNTYPE};
    enum vmeModStatus {OK, WARNING, ERROR, UNKNOWNSTATUS};
    struct slotInfo {
       vmeType contents;
       long serNo;
       vmeModStatus status;
       long revision;
    };

    typedef slotInfo crateInfo[22];

    interface RCC {
       long scanCrate(out crateInfo modList);
    }; /* end of interface RCC */
}; /* end of module CoRCC */
-----------
In my server application, everything compiles and links with no 
warnings or errors.

When I try to build a client, I get the following error message:
-------------
CoRCCClient.cc:92: choosing `T& _CORBA_Array_Fix_Var<T_Helper,
    T>::operator[](long unsigned int) [with T_Helper =
    CoRCC::crateInfo_copyHelper, T = CoRCC::crateInfo_slice]' over `operator[]'
CoRCCClient.cc:92:   because worst conversion for the former is better than
    worst conversion for the latter
-------------

The relevant part of the client code is as follows:
-------------
int ScanCrate(int rccHandle) {
   int status = 0;
   int serNo;
   CoRCC::crateInfo_var modList = new CoRCC::crateInfo();
   status = rccref[rccHandle]->scanCrate(modList);
   for (int i=2; i<NSLOTS+1; i++) {
     cout << "Slot Number " << i << endl;
     serNo = modList[i].serNo;           //<<<< This is line 92, 
where the error is
   }
   return status;
}
