First of all let me apologize for the late reply.
I managed to run your project, however the problems which you described cannot be reproduced:
- when editing an existing record, the main combobox is loaded but the cascade combobox is not.
- when you try to update rows 2 or 3 the Sub Combobox in the popup editor is not loaded at all.
On my side the same behaviour does not occur. Could you please check the screencast and let me know what I am missing?
Thank you in advance.
