Send a default sort specifier along with other any other applied on grid.

Hi Isomorphic ,
I want to always sort order by a default field (which is not displayed on grid as a field but part of response) first before any other sort applied on grid. This is the code I tried.

addSetSortHandler(event -> {
                  event.cancel(); //tried cancelling here and at the end of method as well
                  List<SortSpecifier> specifiers = new ArrayList<>();
                  specifiers.add(new SortSpecifier("default_order", SortDirection.ASCENDING));
                  specifiers.addAll(Arrays.asList(event.getSortSpecifiers()));
                  setSort(specifiers.toArray(new SortSpecifier[0]));
});

This is not working.


Also tried changedHandler

addSortChangedHandler(event -> {
                 List<SortSpecifier> specifiers = new ArrayList<>();
                specifiers.add(new SortSpecifier("default_order", SortDirection.ASCENDING));
                specifiers.addAll(Arrays.asList(event.getSortSpecifiers()));
                setSort(specifiers.toArray(new SortSpecifier[0]));
});

This solution works first time only. For ex : If I click on Name field to sort then this will sort by "default_order, name" and if I again click on name field then it stays ascending only.

Any suggestion how can I do this. Thanks

Both of your attempts have the same problem: when you call setSort(), the SetSortHandler and SortChangedHandler are going to be called again, resulting in infinite recursion - this is reported in the console, so make sure you pay attention to that.

The solution is to adjust your handler code to do nothing if you are called as a result of your own call to setSort().
