i'm trying all sorts of ways to have a ComboViewer , send a particular property from a selected object to another property, the object recieving the property is a bean while the selected object is a pojo, but i cannot find a way to get them to work..

final ComboBoxViewerCellEditor cellEditor = new ComboBoxViewerCellEditor(tv.getTable(), SWT.READ_ONLY);
cellEditorProperty = CellEditorProperties.control().value(WidgetProperties.select ion());
valueProperty = BeanProperties.value(propName);
editingSupport = ObservableValueEditingSupport.create(tv, bindingContext, cellEditor, cellEditorProperty, valueProperty);
tvc.setEditingSupport(editingSupport);

WidgetProperties.selection() looks wrong because when you want to
observe a viewer you'll have to use ViewerProperties but to me it looks
like as if CellEditorProperties does not support this.

Please file a feature request bugzilla.

the closest that i could get was to do a:
PojoProperties.value("viewer" ).value(ViewerProperties.singleSelection().value(PojoPropert ies.value( "id")));

where id is the actuall value i wanna update in the model, but even though it does get updated, the selected object's property in the combo gets updated also! when i move rows.

there is something missing here.
