Hi Matti, 

I am using MGrid for lazyloading which works fine. I use FilterableListContainer to support my FilterBar which works perfectly well on normal Grids. Somehow I am getting following error on moving to MGrid

Could you please tell me how to fix it?

This is my pretty standard lazyloadingfrom function 

getGrid().lazyLoadFrom(new SortablePagingProvider<AggrFoodList>() {

            private static final long serialVersionUID = 1L;

            @Override
            public List<AggrFoodList> findEntities(int firstRow, boolean sortAscending, String properties) {
                return  aggrFoodListRepos.findAll(new PageRequest(firstRow, PAGESIZE, sortAscending ? Sort.Direction.ASC : Sort.Direction.DESC, properties == null ? "id" : properties)).getContent();
            }

        }, new CountProvider() {

            private static final long serialVersionUID = 1L;

            @Override
            public int size() {
                return (int)aggrFoodListRepos.count();
            }
        }, PAGESIZE);

thanks
Chahat
