You shouldn't need to do this, unless you want to change the way
panckoucke access topicmaps.

Ah. I think I see what I did forget in the example. It stops on half
way. Sorry.
Basically, the StoreChangedNotification supplies you with a
TopicMapReference.
If this reference is in state ACCESSIBLE you may call its method
getAMNode() to retrieve an AMMember that represents the TopicMap.
This member is then passed to the getModel(...)-Method of the
ModelProvider, along with an Abstractor that is able to process a
Topicmap-Object.
I just commited an improved version of the ExampleOpenTopicMap-Code to
panckoucke cvs. The example performs theese steps and contains
furthermore a simple renderer, that lists all of the topics in a
topicmap.
Hope that helps
