Yes. And both collections are accessible in the object inspector: The
JvOutlookBar has a property "Pages", the ellipsis button next to it
opens the usual collection property editor which can be used to add,
delete or rearrange pages. And when one of the pages is selected the
object inspector displays the property "Buttons", again with an ellipsis
button to open another collection property editor, now for the buttons.
This part is working out of the box. The problem is the component tree
which only shows the page nodes but no button nodes.

This is for notification of the component tree by the component editor
and this code is already there and working. What I want is notification
of the component editor by the designer if pages or buttons are added
while the component editor is open (the component editor is not modal).
