The UI talks to the filter model. Therefore route clearing of data through that model instead of accessing the source model directly. This will allow us to remove the DiveTripModel::instance() function and makes control flow less "jumpy". Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
