Summary0002490: TjvCalcEdit problems
DescriptionFound two problems with the TjvCalcEdit component.
1. I'm trying to use several components from the "jv Edits" tab. Since i need to treat them uniformly, i'm typecasting them to the common ancestor : TCustomEdit.

Everything is ok when i'm using tJvCalcEdit directly, but casting them to TCustomEdit, the Text property doesn't work. Example :
  myEdit : TCustomEdit;
  myJVCalcEdit : TJvCalcEdit;
  myEdit := TCustomEdit(myJvCalcEdit);
  myJVCalcEdit.text := '123'; // works ok
  myEdit.text := '456'; //doesn't work... the assignment got ignored
This is probably caused by the component overriding the property or something, but I haven't delved into the code yet. Workaround at the moment is special-case handling of TjvCalcEdit... would love to get rid of this hack...:)

  for i:= tcomponentlist.items[i].count-1 do begin
    myEdit := tcomponentlist.items[i] as tCustomEdit;
    if (myEdit is tJvCalcEdit) then begin
       //special case
    end else begin
       //normal case

2. Event onChange() doesn't fire when users are entering data through the 'calculator' instead of typing it directly. This should be easy enough to verify.

Additional InformationTested on Delphi 6.02
