Subclassing TfrxReport

Bill E

I tried to create the following class (see at end of this message) but when I run the report I get an error

"

---

Debugger Exception Notification

Project ExportToNexus.exe raised exception class EClassNotFound with message 'Class TReportGenFRXReport not found'.

Break Continue Help

"

The error is at TfrxXMLSerializer.ReadRootComponent


Here is the class

  TReportGenFRXReport = class(TfrxReport)
  strict private
    FReportID: Integer;
    FTemplateName: string;
  public
    property ReportID: Integer read FReportID write FReportID;
    property TemplateName: string read FTemplateName write FTemplateName;
    procedure Load;
    procedure Save;
  end;

The reason I am doing this is for 2 reasons but the primary reason is to pass context into the Designer Save event. The other reason is simply architecture, in that I want my special Load and Save methods and extra attributes in the report object.

I found a solution but want to make sure it is ok:

I simply did this:

initialization
  frxObjects.RegisterObject(TReportGenFRXReport, nil);

finalization
  frxObjects.Unregister(TReportGenFRXReport);

Is there any problem with passing nil, and is it a problem that I do not make some properties published?

I am confused why it is even serializing the component, and this gives me concern that properties will get dropped.
