| Summary | 0005543: JVCL338CompleteJCL201-Build3449 -JVDBGrid using official "good" BDE version 5.02. | ||||
| Description | due to the following bug in BDE, reported in Delphi BDE Bug list: "Requesting the OldValue property of a Field throws an exception." using an external inplace editor (combo DBLookup control), when I press ESCAPE to cancel editing, it throws exception: 'Not in cached update mode'. I have found the offending line of code in JVDBGrid.pas, and included some text from above web site, which I have verified as a problem above. It is always reproducible. See included txt file for details. | ||||

the project contains several custom components and would not compile on your system. I do not have time right now to dissect my custom controls out of the project and bundle it up for this request. However, I applied the 2nd suggestion (below) in my source code, recompiled, and it fixed the problem: Suggestion from "the Delphi Bug list": Enclose the code that utilizes the OldValue property of a field in a try-except block OR check if the 'State' property of the DataSet is dsEdit before attempting to get the OldValue of a field. <--- this worked good in my JVCL |
