Hi,
Thanks for the answer.
I've forgotten to write it; the setDynamicSortFilter propriety is set to true in the proxy (in c-tor), but not in the model. Hence the proxy shall filter and sort I think that it is correct.
Shall I set it also in the model?
The other thing is, that without invalidation proxy reacts "somehow" on the changes,
e.g. after insert rows everything works fine. Problems seem to occur when rows are removed.
I am grateful for further hints.
