Hi All,
          I am using function batch_mutate of cassandra 0.7 and I am getting the error InvalidRequestException: Mutation must have one ColumnOrSuperColumn or one Deletion. I have my own C++ cassandra client using thrift 0.0.5 api.

Any Suggestions.

Sample Code
    map<string, vector<Mutation> > cfmap;
   
    vector<Mutation> mutations;

       Column temp_col;
        temp_col.name.assign("abcd");
        temp_col.value.assign("efgh");
        temp_col.timestamp = timestamp;
        temp_col.ttl = 0; // TODO: TTL
        ColumnOrSuperColumn cosc;
        cosc.column = temp_col;
        cosc.__isset.column = true; // must set which data type, col or super
       
        Mutation mutation ;
        mutation.column_or_supercolumn=cosc;
        mutations.push_back(mutation);

       cfmap.insert(make_pair(colspace, mutations));
    map<string, map<string, vector<Mutation> > > mutationMap;
    mutationMap.insert(make_pair("firstRow",cfmap)) 

conn->client->batch_mutate(
            mutationMap, (org::apache::cassandra::ConsistencyLevel::type)cons);


Thanks
