Cascading Custom Property

I am currently building a custom property which is a collection of custom properties. Parsing and storing of this collection works fine as I transform the whole tree into an XML-document.

When I open the page the first time, the 'CreateEditControls' of the collectino is called, which creates property-controls for every property inside. Every property-control creates the necessary property-controls for it's properties (PropertyXhtmlText, PropertyPageReference, etc.).
Afterwards, SetupEditControls is called which loops through the property-controls and calls 'SetupControl' for every one. These calls call SetupControl for their sub-controls.

The problem is with the postback. When I click 'Save', the method 'CreateEditControls' is called for the collection and property-controls are (re-)created. But for some reason, while creating the property-controls, the CreateEditControls-method of the sub-properties is never called.
This results in SetupEditControls to fail.

Can anyone explain why the method of the sub-properties isn't called the second time?

Or is there a different way of re-creating the controls?

The trick is to craete the properties every time, and on prerender save the new xml structure, and use that for recreating.

A little tip. Use the Property SaveData and LoadData instead of the ParseToSelf() and Value.ToString() since the load and save handle the LinkCollection correct

It sounds like it could be doing just what you are trying to do?
