Hello, this is the situation (lazarus 0.9.29 - fpc 2.3.1):
TMyClass = class
  private
    FNotifica: TNotifyEvent;
      procedure SetNotifica(const AValue: TNotifyEvent);
published
  property Notifica: TNotifyEvent read FNotifica write SetNotifica;
end;
var MyClass: TMyClass;

This is OK.

On another unit, I have:

TAnotherClass = class
public
  procedure DoNotifica(Sender: TObject);
  procedure SetLinks;
end;
procedure TAnotherClass.SetLinks;
begin
  MyClass.Notifica:=self.DoNotifica; // <--- This is the problem
end;

and, when fpc compile this I get:

fopessoas.pp(41,39) Error: Wrong number of parameters specified for call to
"NotificaInfo"
fopessoas.pp(22,15) Hint: Found declaration:
TfPessoas.NotificaInfo(TObject);
fopessoas.pp(91) Fatal: There were 1 errors compiling module, stopping

Well, what can I do?

 ; // <--- This is the solution

I swear I tried this before, but the error was the same. Now, it worked! Must be the elves who live under my desk!

Thanks

Well, new problem.

The compilation is ok.
But, in run-time I get:
Project de.exe raised exception class 'EReadError' with message: Invalid value for property

May be an unrelated issue.

Check if the *.lrs file is ok. Or simply delete the lfr file (while the form is open) and save the form, so the file is created again.

Do you use VirtualBox? (There is an issue which leads to this error)

Ok, this is the explanation:

The MyClass is TFrame, and docked into another form (TAnotherClass). I've altered some properties on the frame, and this was not reflected on the object in the form.
So, I deleted the frame and inserted a new one in the form. Everything is ok now.

Thanks for the help.
