Re: [platform-ui-dev] Initial General Purpose Navigator proposal

Knut,

Here are some comments and questions:

Provide a viewer that displays hierarchical data.

Will the navigator be strictly a TreeViewer on the inside?
The new Live Sync Vew (available in today's integration build) can optionally
show a table containing the filtered changes. It would be great if the
general purpose navigator could support this as well. However, if that
is not possible or practical, it would be very helpfull if the general
actions (cut, copy, paste, etc) were reusable (i.e. not tied to a TreeViewer)
so we would not have to reinvent everything (The way it stands now, we
will need to do this because many of the "reusable" resource
navigator actions are tied to a TreeViewer).

Allow filters

We've done some similar filtering in the new sync view.
One interesting challange is the pruning of empty directories from the
view (i.e. those directories that existed but whose files were filtered
out). We had to cache all visible files so we cold know which folders needed
to be shown.

Action Contributions and Modes

We had this requirement in the sync view as well. The
logical elements in the view are always the same type (IResource) but the
selected subscriber (CVS workspace, CVS merge or some other subscriber
like FTP or WebDAV) determines which resources appear and which actions
are available. We had to create our own object contributions to support
this because, as far as I know, the current objectContributions only filter
by project nature and persistant properties on the project. A more general
objectContribution filtering mechanism would be helpful.
