assertion failure

hi,

im opening a table in a form where this table is not updated with new fields. so an error occurs : field 'xxx' not found. which is normal.
but once i close the form, an error occurs : 'assertion failure
(D:\Projects\Delphi\Dac\Source\MemDS.pas, line 2563).
i traced my code and i found that this error is raised due to my code :

procedure TMyForm.FormClose(Sender: TObject;
var Action: TCloseAction);
begin
...
table.cancel;
...
end;

i added this code :
if Table.State in [dsEdit,dsInsert] then
table.cancel;

and its working now.
but i need to know what is this bug and how to avoid it.
might appear later on another function rather then canceling table.
any sugestions?

Thank you for information. This bug appears when the recordset is not defined. We have reproduced this problem and fixed it. This fix will be included in the next MyDAC build.
