[CDO] Closing transactions created in view provider [message #1220247]

Hi all!

Where I should close a transaction opened in contributed CDOViewProvider?
I've implemented one, using the following doc as a reference:
http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.emf.cdo.doc%2Fhtml%2Fprogrammers%2Fclient%2FViewProviders.html

But i have found out, that once opened that transaction is never closed.
Where is it supposed to be closed?

Many thanks in advance!

In theory you could attach an adapter to your resource set and listen to resource removal. Whenever that happens you
could iterate the list of remaining resources and determine if the opened transaction is still needed. But you'd also
need to ensure that unneeded resources are properly removed from the resource set at some point.
