OnComponentChanged/Events not fired at DesignTime with Custom Control/Designer

I'm creating a custom web control to be modified in the VS designer.
I'm using a very simple class to get my feet wet.
The AngelPage (extends WebControl) which exposes a custom class,
DefaultHeader. I'd like to modify the DefaultHeader properties at
design time.
In addition to these two classes, I've also created a
TypeConverter
and
a
ControlDesigner
(PageDesigner) class. I have two basic problems:
1. The properties are correctly displayed in the designer, however, the
modified values are never being written to the Test.aspx file
(expectation is too see modified values appended to tag reference in
HTML view)
2. When debugging this project (using devenv), I noticed the
onComponentChanged event is never fired.
I suspect both of problems share a common root cause. I'm sure it
amounts to a very simple problem. Is there an additional step to
registering a custom designer to fire events for modified properties?
Any help would be greatly appreciated. Code files inlined as zip for
reference
Thank you

Marcie,
Are you trying to replace the default page designer for one of your page

Marcie (aka Maurice - :)
No, I'm just trying to expose a Complex type in a Custom Control in the
designer. I would like to create a control hierarchy (i.e.
MyCustomControl -> BaseControl (contains multiple properties common to all
developed controls) -> Web Control. I have no problem in seeing the
inheritied properties in the property grid. The problem arises when
modifying these properties. The data values are never persisted/written in
the aspx (html) file. Maybe I'm not extending from the correct class
"WebControl" versus "Control". Or maybe, I've missed overriding a particualr
method.
Thanks,
Maurice
