Hello! When I try to query the interface, which is implemented by the ancestor of the class of the current object, but not it immediate class, then the QueryInterface returns nil. But it is not right because this interface is implemented really.
And as solving this problem, I am offering a small correction in the
RTL-source file inc/objpas.inc. Diff file is attached.
