Clear Filter values of Table

UseCase: We have to manually remove the table filter values we've entered.Instead provide an action Button/Link with the following method on Button Action, to clear all the entered filter values and reset the table.

1. public void resetTableFilter(ActionEvent actionEvent)
2. {
3. FilterableQueryDescriptor queryDescriptor =
4. (FilterableQueryDescriptor) getEmpTable().getFilterModel();
5. if (queryDescriptor != null && queryDescriptor.getFilterCriteria() != null)
6. {
7. queryDescriptor.getFilterCriteria().clear();
8. getEmpTable().queueEvent(new QueryEvent(getEmpTable(), queryDescriptor));
9. }
10. }
