Error when FormatOptions.Enable := True and field is NULL

[INFOSYS]

Hi,
this is the condition:

Code: Select all

  with IWCGJQEdit3 do begin
    datalink.dataSource := ServerController.UserSession.DataSource1;
    datalink.FieldName := 'val';
    FormatOptions.Enable := True;
    FormatOptions.AllowNegative := False;
    FormatOptions.AutoFix := True;
    FormatOptions.Precision := 0;
    FormatOptions.Type_ := ftDecimal;
  end;


When execute ServerController.UserSession.DataSource1.Post and the field 'val' (connected to IWCGJQEdit3 ) is NULL, an EConverError exception is fired with the

Note
"" is not a valid floating point value

message.

I know that

since 3.5.0.210, the component is using the system FormatSettings to convert string to float

but I think that if the field is null no exception must be fired...

Best Regards, Alfredo.

Hi Alexander,

I'm sorry but on 4.0.0.7 release the format error (when field is null) is still present...

Just checked out on Delphi 10.2 and Intraweb 14.1.13

Hi,
just installed new 4.0.0.9 CGDevTools version and your demo now works as expected (no more floating poin conversion errror).

BUT

compiled on 64 bit It's OK, when I compile on 32 bit I got an external exception executing (after run):
