TWebDBCheckbox bugs

Hi,
I have encountered a couple of issues with the TWebDBCheckbox component (Latest release 2.8.3.0).
First bug:
The current behaviour of the checkbox doesn't allow me to use the new value immediately after it has been set. The underlying field value is set ONLY on Post method of TwebClientDataset, it doesn't seem to always post as soon as a change happens, as other Dbeditors does.
This is a big problem, and cause errors, especially when Standalone Editors are syncronized with grids.
Second Bug:
When working with a WebDBCheckbox connected to a TStringField (ValueChecked = S, ValueUnchecked = N) and the same dataset is connected to a FNCDataGrid (with relative adapter), I get "Cannot set properties of null (setting 'myfield')" when posting or navigating to a new record. It seems that adapter don't works well in this situation.
Thanks
