[osg-users] Serialization always says: Unsupported associated class osg::Object

[John Pasnom]

Hi,

using OSG 3.0.1 I've implemented a custom class deriving from osg::Object that should support serialization:

The register object wrapper looks like this:


Code:
REGISTER_OBJECT_WRAPPER( MyLights,
new dx::MyLights,
dx::MyLights,
"osg::Object dx::MyLights" )
{
ADD_USER_SERIALIZER( VisionLight );
}




While the serialization to osgt works perfectly I still get msgs during serialization:


> OutputStream::writeObject(): Unsupported associated class osg::Object
> InputStream::readObject(): Unsupported associated class osg::Object


Why is that happening? I know this occurs because my inheritance says "osg::Object dx::MyLights" but I've searched through the osg source for classes deriving from osg::Object and they all do the same inheritance, first osg::Object then their own one

Example:


Code:
REGISTER_OBJECT_WRAPPER( AutoTransform,
new osg::AutoTransform,
osg::AutoTransform,
"osg::Object osg::Node osg::Group osg::Transform osg::AutoTransform" )



How can I properly solve this? Leaving osg::Object simply out? Or do all those classes generate serialization messages?

Thanks

Hi John,

In principle the code snippets you have provided look OK.

Like in my previous email, it could well be a bug that has long been fixed - OSG-3.0.1 was released along time ago.  Without specific code to test against there isn't any way to know the answer.
