David and Subbu,
Thank you for your explanations, but ... but we have characters in the
image. Having a characters in the image means that Character has instances.
If alInstances method cannot report about them, it shall fire exception
perhaps, or, name allInstances must be changed to something else, isn't it?
regards,
Vaidotas
