I would like to use TMS object serialization to JSON. However, when working with a TTMSFNCTileList, calling the AWidget.FromJSON function results in an error indicating that the object TTMSFNCTileListItem was not found (Vcl.TMSFNCPersistence).
How can I resolve this issue?
We have investigated this here and seen the missing register in our sources. We'll fix this here.
What you can do as a workaround, call RegisterClass(TTMSFNCTileListItem) before persisting to JSON.
