Hi Felix,
Something odd must be going on with the scene graph should be
independent from any state, there should be no reason that state
should be applied before geometry calls. If there is a problem then
changing the order is probably just masking the issue.
Could you explain the role of invalid vertex program?

Hello.
I was getting GL_INVALID_OPERATION on a glDrawArrays() call in
Drawable::compileGLObjects() / Geometry::drawImplementation(). I
traced it down to GLObjectsVisitor::apply(osg::Geode node) which
does:
apply(*drawable);
if (drawable-getStateSet())
{
apply(*(drawable-getStateSet()));
}
... so because the drawable is drawn before it's stateset was applied
an invalid vertex program was used (which caused the
GL_INVALID_OPERATION error). Changing the order there fixed the
problem for me.
I checked trunk - the problem is still there.
Cheers,
Felix
