Re: getting team synchronization to work?

The syncronization support is NOT complete.

Currently there are many things that can't be effeciently implemented due to
the fact that the Javahl bindings are a work in progress and only cover a
small subset of the svn API.

Currently there are 2 implementation of the Subscriber
1. SVNSubscriber
This one calls SVNClient -r HEAD -R to get the whole remote tree

2. SVNWorkspaceSubscriber
This is the one currently enabled. Internally it uses 'svn status -u' to
populate a tree of changes.
This is prefered because 'svn status -u' is implemented very efficiently in
the core subversion libraries.
It has some drawbacks like, if a resource is added in the repository,
subversion reports this file as of
UKNOWN kind (neither a file nor a folder).

As I said before I think that the second approach is the way to go.
Currently I am working on getting the SVNWorkspaceSubscriber to listen to
resource changes and to update itself to reflect those changes.
I will try to clean up this code and commit it so you can work on it.

The SVNSubscriber should be kept if we want to implement a 'Compare with
revision/tag/branch' functionality. This kind of functionality can't be
addresed with the use of a 'svn status -u' command.

About the UpdateSynchronizeOperation, I think that these where copied from
the filesystem example and they have to be adapted to svn.
