Hi,
We have a view that is opened in serveral instances (allowMultiple, with
secondaryId set).
It seems like the normal view lifecycle process is performed only on a class
level (e.g. only for the first instance).
Is this a correct observation? How to handle persistance in such a case?

Hi and thanx for fast reply.
The problem we have encountered is when the views are left remaining open
when the user ends Eclipse (or closes the perspective)
When the perspective is restored the view init and createlPartControl seams
to be invoced just onces (not once for every view instance as expected),
which makes
it hard to restore the content for each instance of the view. The apperance
now is empty blank views with the view id as the name in the caption for all
views.
I saw something in your answer that gave me an additional question. In you
sample the first view is opened whitout the second id set:
page.showView("id");
page.showView("id", "1", IWorkbenchPage.VIEW_ACTIVATE);
page.showView("id", "2", IWorkbenchPage.VIEW_ACTIVATE);
But our solution does:
page.showView("id", "1", IWorkbenchPage.VIEW_ACTIVATE);
page.showView("id", "2", IWorkbenchPage.VIEW_ACTIVATE);
page.showView("id", "3", IWorkbenchPage.VIEW_ACTIVATE);
In this case there will be no instance of a view without any second instance
id set. Perhaps this can be problem?

Hi again,
I just realized that the init and createPartControl is invoced only once
because there is only one view that has focus.
By clicking on the other views the init and createPartControl is invoced!!!!
Well that is good to know, but not sure how I can use this info. One could
of course fake a focus on each view, but
that seems to be work around not a solution.

Using secondary IDs for all of your views should be fine.
All parts (views and editors) are lazily restored after a session
restart. Why do the work to populate a view if the user never clicks on
it? That view saved-state will be propagated through session restarts
until the user finally clicks on the view.
