| Summary | 0006648: TJvDateEdit CheckOnExit gives double error message | ||||
| Description | When you have 2 TJvDateEdit components on a form, the CheckOnExit displays the error message twice when you click on the other TJvDateEdit. Example: - Put 2 TJvDateEdit components on a form (JvDateEditA and JvDateEditB) - JvDateEditA has CheckOnEdix set to true - Enter an invalid date like 54.98.2465 in JvDateEditA - Click on JvDateEditB - Get 2x error message '54.98.2465 is not a valid date.' This only happens when you CLICK on JvDateEditB. If you use the TAB KEY to switch to JvDateEditB then you get the error messsage only once. | ||||

I have attached a very simple example that shows the problem as explained. |

Some first analysis: 1. the provided test application doesn't work out of the box. The dpr needs to be modified like this, otherwise no form will be created: program JvDateEditTestProject; uses Vcl.Forms, JvDateEditTest in 'JvDateEditTest.pas' {Form1}; {$R *.res} begin Application.Initialize; Application.MainFormOnTaskbar := True; Application.CreateForm(TForm1, Form1); Application.Run; end. 2. There is a method CMExit in TJvCustomComboEdit which is triggered by a message CM_EXIT. It looks like this method is being triggered twice and there is the FInCMExit field which seems to be there to prevent double calls. Looks like the CM_EXIT message is not declared as completely processed. But why then doesn't this happen when using the keyboard instead of the mouse? There it only triggers this once. |
