Suppose after further reflection, it becomes apparent that the revision of file1.txt that was just received is incorrect and an earlier revision is required. A Workbench resource can be replaced with an earlier revision of the resource from the repository. To roll back to an earlier revision:
In one of the navigation views select the file1.txt.
From the file's context menu, select Replace With >
Revision.
In the replace with revision Compare editor that opens, choose
the original (bottom) revision and, from the pop-up menu choose Get Contents.
Observe that the navigation view updates to show the CVS state of a resource.
Notice that the modified file is preceded by ">" (see #1) indicating
that file1.txt has changed (by replacing it with the earlier version).
Instead of choosing Team > Synchronize with Repository, choose Replace With > Latest from Repository.
Observe that file1.txt is updated to be the contents from the repository, and that the leading indicator ">" has been removed since it is now the same revision as the repository.
Now that how to synchronize with the repository, replace with a revision or replace with the latest from the repository has been explained, these revisions/versions can also be compared with in a similar manner by choosing the Compare With menu operation from a resource's context menu in the navigation view.
