pq20130 - "UndefinedObject does not understand value" walkback
when opening a notebook with a container.	
---------------------------------------------------------------------

Affected Platforms:

 All


Affected Features:

 Application Builder

Prerequisites:


 v4.02b


Symptom:

Customer's application dynamically creates a form and places
it in a containing window using the subpartNamed:put: message.
The openWidget message is sent to the form after it has been
added as a subpart to the window.  If there is an existing form
in the window, it is removed using the removeSubpartNamed:ifAbsent:
 message and saved away for later use. 

The problem occurs when an existing form that has a portable
notebook and a container on one of the pages is re-opened.  Again, 
the openWidget message is used to open the form.   When the form 
is opened, the notebook and its pages get created but the components
for a page aren't created. The reason the components aren't created 
is because the componentsCreated flag has a value of true.  This flag 
gets set to true in the AbtPortableNotebookPageView>>initializePageWidgets 
method but it never gets reset to false when its containing form is removed from the 
window using the removeSubpartNamed:ifAbsent: message.
   

Solution:

 Open a workspace on pq20130.st and file in the fix.
