Problem:

IDL2CPP generates C source file that cannot be compiled. Consider the following declaration in sample1.idl:
typedef sequence GroupNumbers;

If sample1.idl has a function with return type of GroupNumbers, the idl2cpp compiler will generates a .cc file that cannot be compiled to obtain an object file. The error is: `_VISanon_seq_0_string_ptr" is not a member of `mcx::dbdrvi::XXXX"

The return type would be

CORBA::StringSequence* _ret = (::mcx::dbdrvi::HuntSite::_VISanon_seq_0_string_ptr) NULL;

Resolution:

A defect CR 9343 is raised and the resolution is incorporated in service pack level 3 releases of the VisiBroker 7.0. The fix would provide valid typecast for the function in the .cc file generated.

The correct generated source should be as follows:

::CORBA::StringSequence* _ret = (::CORBA::StringSequence*) NULL;
