(is platform the correct newsgroup for JFace Data Binding questions?)
Is it possible to use binding with virtual tables? If so, how would one
do that?
If binding to a regular table with SWT.VIRTUAL style isn't possible,
then I understand that binding is supported with CompositeTable, which
is similar to a virtual table? But what are CompositeTable's other
advantages over a regular virtual table -- why would I use CompositeTable?
If it helps to answer the questions, we are building an RCP application
which is mostly a user interface to a database -- we will have editable
tables that mostly correspond to database tables.

Hi,
Well I've implemented my own database binding framework and we are in
the process of releasing it to the public. I wanted to release it since
a month but hadn't the time to do so.
One more sentence to SWT.VIRTUAL: There are some problems with Viewers
and Virtual Tables and you can't really use them at the moment to edit
(add/remove items) tables.

I finally had time to get a bit more of an understanding of the
Databinding framework, and it looks quite awesome!
We are most likely going to use it, and perhaps can even contribute
something (at least more eyes for finding bugs).
