Hi,
I guess i did not gave enough description to my problem...
I have a custom catalog, and it does not appear to support selection.
Until now, Ive done:
added to view plugin in createPartControl method
final ISelectionService selectionService =
getViewSite().getWorkbenchWindow().getSelectionService();
selectionService.addSelectionListener(new WorkbenchSelectionListener());
where WorkbenchSelectionListener implements ISelectionListener.
and there implemented selectionChanged,as shown
public void selectionChanged( IWorkbenchPart part, ISelection selection ) {
updateSelection((IStructuredSelection) selection);
}
private void updateSelection( IStructuredSelection selection ) {
Object selected = selection.getFirstElement();
final Layer selectedLayer;
if (selected instanceof Map) {
selectedLayer = ((Map)
selected).getEditManagerInternal().getSelectedLayer();
} else if (selected instanceof Layer) {
selectedLayer = (Layer) selected;
} else if (selected instanceof AdaptingFilter) {
AdaptingFilter adaptingFilter = (AdaptingFilter) selected;
selectedLayer = (Layer) adaptingFilter.getAdapter(Layer.class);
} else {
return;
}
GetSelectedFeaturesFromLayer.getSelectedFeaturesFromLayerRestrictedToFIDs(selectedLayer,
null);
}
and there, while calling getSelectedFeaturesFromLayerRestrictedToFIDs,
i get exception that schema is null.
getSelectedFeaturesFromLayerRestrictedToFIDs can be found here:

any ideas?
Thanks,
Milan
