How to add multi dimensional IloRangeArray to the model on CPLEX

I'm a beginner in CPLEx and using it to wite my mathematical model. I defined and built a three dimensional IloRangeArray as my constraint as follows:

typedef IloArray<IloRangeArray> TwoDimRange;
con = IloArray <IloArray <IloRangeArray> > (env, n);
for () 
{
    con [h] = IloArray <IloRangeArray> (env, nbRow);
    for ()
    {
        con[h][m] = IloRangeArray (env);
        for () 
        {
            IloExpr tempExp(env); 
            if ()
                 con [h][m].add(0 <= tempExp <= 0);
        }
    }
}

When I want to add "con" to the model (model.add(con);), I have the following error:

error C2664: 'IloExtractable IloModel::add(const IloExtractable) const' : cannot convert parameter 1 from 'ThreeDimRange' to 'const IloExtractable'

It is the same for 2 dim IloArrangeArray. What is your opinion?

Thanks
