Guillaume,
I don't know exactly what the problem is, but as a general rule whenever
you see ClassCastException on an instance of DynamicDataObjectImpl it
means that the generated SDO class isn't registered/available. SDO is
"smart" and if there's no generated class for a particular type it uses a
dynamic SDO implementation class for it. This is the right behavior if
there really is no generated class, but if clients expect one, you
generally get this kind of ClassCastException.
Frank.
