I've tested it (an Update) and it definitely is not behaving sensibly:

1. Check out as a project
2. Modify Bar.java and commit as another user
3. Delete Bar.java
4. Sync and find a conflict
5. Update Bar.java. It displays a warning: "you have local changes that
conflict with the server. Update will attempt to merge those changes. do
you want to continue?". Choose "Yes".
6. Bar.java (14) displayed in the sync view becomes Bar.java (BASE). It
becomes from a conflict into an incoming change. The file in package
explorer is marked in error (red cross). The content of the file is the
latest version.
7. Performing an update again will NOT get rid of that incoming change.
8. Try to mark it as resolved in the package explorer. But the red cross
9. Performing a sync will tell me that no changes found.
10. Modify Bar.java and sync, it will tell me that no changes found.

The corresponding console output is:

checkout -r HEAD file:///c:/repo/prj/trunk
    A C:/workspace/SVNTest/Bar.java
     U C:/workspace/SVNTest
    Checked out revision 13.
delete --force C:/workspace/SVNTest/Bar.java
    D C:/workspace/SVNTest/Bar.java
update -r 14 -N C:/workspace/SVNTest/Bar.java
    U C:/workspace/SVNTest/Bar.java
    Updated to revision 14.
    ===== File Statistics: =====
         Updated: 1
resolved C:/workspace/SVNTest/Bar.java

Of course, performing a revert after a conflict is found works.

As shown above, the problem here is that after performing an Update,
there is no way to resolve the conflict. I think this is not an
acceptable behavior.

I'd suggest that:
To perform an Update, it should put the latest content into Bar.java
with markers. It should create Bar.java.old-release# and
Bar.java.new-release#. The user needs to mark the file as resolved
before he can commit.

Instead of performing an Update, the user may mark the file as merged
in the sync view. If the user leaves the file as non-existing, it means
to delete it. If the file exists, it means to to use it as the merged

If the above behavior is too hard to implement, you may consider to
simulate the behavior of the command line client:
To perform an Update, it will create an unversioned Bar.java. The user
must mark it as resolved before he can commit.
