It's a bug in UIB. But it's a bug that most TDataset-descendents suffer from. That's because the bug is hidden in Delphi. It is also hidden in fpc's released versions, because it causes too much trouble. But this "bug" does pop-ups in the development version. Until all TDataset-descendents I know of have fixed it, it will be hidden in released versions, though. > The same program works when using fpc 2.2.3. > > For demonstrating the problem I created the following program: > > When trying to open an UIBDataset I get an error: "EDatabaseError : > Invalid field size : 4828" Which is true, 4828 is an invalid field-size for an integer-field. I guess that UIB doesn't set the field-size properly. In fact, the 'field-size' property should contain the amount of decimals in this case. So the field-size should be set to 0. Maybe you can look it up in UIB where it's set?
