VirtualTable/Query are empty after LOADED

VirtualTable/Query are empty after LOADED

Hello

I just bought the VirtualDAV (v12.2) Components for my Delphi 11.2

Attached a small demo program, that shows my problem. I load/assigned the data in the LOADED Methode, after i entering on the FormCreate Methode the vtElementGrafik VirtualTable are empty and the query shows me nothing.

Do you have me a hint to solve my problem?

Thanks in advanced
