Reset PrimeFaces DataTable state (filter, sorting, paging)

Question

I'd like to reset the filter, sort and paging state of an PrimeFaces DataTable. Unfortunately, there is no easy way to do so. Especially reseting the sort state is difficult. What I did until now is: ``` DataTable dataTable = (DataTable) FacesContext.getCurrentInstance().getViewRoot().findComponent(componentId); if (dataTable != null) { dataTable.setSortOrder("ascending"); // reset sortOrder dataTable.setFirst(0); // reset page dataTable.setFilteredValue(null); // reset filter dataTable.setFilters(null); } ``` I'm using PrimeFaces 3.4.1.

Accepted Answer

Finally, I found the solution, hidden in this sample http://www.primefaces.org/showcase/ui/data/datatable/columns.xhtml on tab `ColumnsView.java`:

```
table.setValueExpression("sortBy", null);
```
