setStopOnErrors=true in listgrid suppress tooltips

[la123]

Hi,

I am using SmartGWT 2.3 in IE8

I have a listgrid with a flag stopOnErrors=true.
If user removes a value from required field in grid, he sees a validation error icon, but there is no tooltip over the icon. If I set stopOnErrors=false, error tooltip is shown.

What's the purpose of stopOnErrors=true, if user sees no error? How can I show tooltips in stopOnErrors=true mode?

        grid = new ListGrid();
        grid.setWidth(550);
        grid.setHeight(224);
        grid.setShowAllRecords(true);
        grid.setCellHeight(22);

        ListGridField nameField = new ListGridField("name", "Name");
        nameField.setRequired(true);

        ListGridField continentField = new ListGridField("description", "Description");

        grid.setFields(nameField,continentField);

        grid.setAutoFetchData(true);
        grid.setCanEdit(true);
        grid.setEditEvent(ListGridEditEvent.CLICK);
        grid.setEditByCell(true);
        grid.setStopOnErrors(true);
grid.setData(recordsArray);

thanks
