[xsd-users] Ambiguous ostream operator

[david.r.moss at selex-comms.com]

All,

using xsd-3.0.0.b1-i686-windows and compiling the attached schema with

 

xsd cxx-tree --generate-serialization empty-list-test.xsd

i get the 'error C2593: 'operator <<' is ambiguous' error with the 
following code:

auto_ptr<class root_t> db( root( "empty-list-test.xml" ) );
test_list_t& l = db->test_list();

//         cout << "list:" << l << "." << endl;   // FIXME: ambiguous << 
operator (list, simple type or type)

if( !l.empty() )  // never empty with v2.3.1!
{
   cout << "\tfirst item:" << *(l.begin()) << "." << endl;
}

any ideas?!

I discovered this while trying to figure out why an empty list read from 
file (see attached xml) resulted in an object containing one 
(garbage-looking) item - i was using xsd version 2.3.1 at the time; that 
bug seems to have been fixed in 3.0.0.b1!

Cheers,
Dave.
