[osg-users] SubloadCallback on iOS: missing texture.

I'm trying to use a SubloadCallback to update a NPOT texture in an app for
iOS. Actually the very same logic seems to work fine on a PC but on iOS it
is not working: I always get a flat-white color on the plane supposed to be
textured (I'm referring to the examples about SubloadCallbacks that can be
found in the forum and I'm using the latest tagged version of OSG 2.9.12).
When I execute the app, I notice that the load method generates this
*Warning: detected OpenGL error 'invalid operation' at After
and the subload method:
*Warning: detected OpenGL error 'invalid operation' at after
Is there something that must be done for iOS in order to successfully use
SubloadCallbacks? By the way, I also tried to override
the textureObjectValid(.) method so that it always returns true (as
suggested in another thread), this makes it to work on a PC but not yet on
Thank you for your help.
