Exception raised when setting Text property of TEdit in custom component (Lazarus) - custom-component

Question

Using: Lazarus 1.2.0; Windows 32-bit application
I have created a custom component derived from TCustomPanel and contains some TEdit controls.
At runtime, when I try to set the Text property of an edit control in my component, I get a runtime error.
This is the error:
Project project1 raised exception class 'External: SIGSEGV'.
In file '.\include\control.inc' at line 3246:
GetTextMethod := TMethod(#Self.GetTextBuf);
I Googled and could not find anybody else reporting this error specifically when setting the Text property of TEdit.
This leads me to believe that I did something wrong when writing the component. Please check my code and point out what is wrong and how to fix it. TIA!
Code follows:
unit uEditPanel;
{$mode objfpc}{$H+}
interface
uses
Classes, SysUtils, LResources, Forms, Controls, Graphics, Dialogs, ExtCtrls, StdCtrls;
type
{ TEditPanel }
TEditPanel = class(TCustomPanel)

Solved. Answer posted by user JuhaManninen on the Lazarus support forum:
"You have no constructor in your class. Replace CreateWnd with a
constructor."
