The section below is the workbench restoring it's state, and activating
(and then instantiating) your view part.
The section above (I know it looks funny writing it this way) is your
view part init adding a selection service that is adding a tracker that
is looking for your (partially instantiated) view part.

In PagePartSelectionTracker, is partOpened() being called shortly after
the constructor with your view part?

PartOpened is being called oddly as a way to register listeners. I'm
not calling it the architecture is.
I am adding a selection 'listener' not service, that listeners only to
this part. And it seems as if the part is being created in order to
register the listener to it. So the part gets created then 'opened' in
order to register this listener which just does not seem right.
Supposedly the listener will only be added AFTER the part is created if
the part is not currently created.
So the registration act is causing the creation. Seems like a bug.
Though probably registering this listener in the constructor would fix
this. But I don tknow how to do that without a site.
I tried to register the listener before super.init was called within the
init method, but the registration still causes the exception.

I checked and its WindowPartSelectionTracker constructor that seems
bugged. it registers a page listener so it can add the appropriate
selection listeners when the page is opened. But its not satisfied to
wait so it requests a list of all pages, then it adds its listeners
right away (by firing on its own listener's pageOpened method). That's
the beginning of the error and does not seem necessary!?
during the add of its listeners it asks for the page by ID with
restore=true, so the page is restored while its still in its init method.
is this a bug or not? Maybe i can add my selection listener in my
partActivated event...

Having the architecture call partOpened() to register the site which
will happen after the recursive warning shows up is correct behaviour
(believe it or not).
What you had initially, registering the listener in the init() method,
looks like correct usage. The recursive warning is a framework notice,
but the partOpened() call insures that behaviourally, your selection
listener is doing what it's supposed to be ... it's a warning in the
workbench start up scenario.
If you want to open a bug report against Platform UI to investigate it
as a clean-up exercise someone will look at it (eventually :-).

Of course one can not expect folks to ignore the warning and watch the
log file build up making it hard to parse and less useful. I did use
partOpened and partClosed for my event. works fine now. It seems like
the architecture artificially calling partOpened is wrong. It says the
listener will be added when the part is created, instead it creates the
part in order to add the listener.
I got bigger fish to fry though :)
