Open the 'Integrated Changes' view with the Eclipse menu 'Window | Show View | Other... | PureCM Views | Integrated Changes View'. Select the project from the drop-down.
The 'Integrated Changes' view shows all changesets which have been integrated in the project workspace (i.e. submitted to the server and then updated into the workspace). If a changeset has been submitted to the server but the workspace has not been updated then it will not appear in the list.
You can view the items within a changeset by double-clicking the changeset or right-clicking and selecting 'View'. This will display all the items belonging to the changeset.
To refresh the list of changesets you must right-click the view and select 'Refresh'.
