'Type Invalid' exception when accessing an empty collection from c++

[Veranika Liaukevich]

Suppose I have an empty collection and try to access it from a c++ code with the following code:

r_Set< r_Ref< r_GMarray > > set;
r_OQL_Query query("select a from $1 as a");
query << collectionName.c_str();
r_oql_execute( query, set );

This gives me 'Type Invalid' exception. If a collection isn't empty or the set variable has type r_Set<r_Ref_Any>, everything goes as should.

Can be tested in source:manuals_and_examples/examples/c++

To test just create an empty collection with rasql first.
