do anyone (especially Matti) know how to solve this issue?

I am also not able to filter the MTable

SortablePagingProvider<People> pageProvider = new SortablePagingProvider<People>() {

      public List<People> findEntities(int firstRow, boolean ascending, String sortField) {

        return peopleCollector.collect(ascending, sortField, filters);

    CountProvider countProvider = new CountProvider() {

      public int size() {
        return peopleCollector.countPeople();

    peopleOverviewTable.lazyLoadFrom(pageProvider, countProvider, pageSize);

I think Pere is right here. Your findAll method seem to sanitize the end index properly, so the MTable must be requesting a page that start beyond the end of your list.

BTW. I guess you are just prototyping with it currently, but wanted to underline that lazy binding don't help you to save any memory, if your data is in JVM memory anyways as in your and mine example. The real queries must happen in the DB layer.

cheers, matti
