Probably you have a published member in your class which is not a descendent
of TPersistent. Only TPersistent descendents can be published members of a
class (which in itself must be a TPersistent descendent).
So, if TPressObject has a published property
Property MyProp : TMyPropClass Read...
then TMyPropClass must also descend from TPersistent.
