setting default value in primefaces datatable Filter

Question

I am using primefaces v3.5.On the datatable I am using filter on one column. How can I set a default value to the filter while loading the page Itself.

Answer 1

The correct solution is to use the filteredValue attribute of p:dataTable which contains the filtered collection together with filterValue attribute of p:column to show the filters configuration to the user.

To keep your p:dataTable filters stored in your session bean, you have to keep also the filtered data. The p:dataTable wouldn't perform the initial sorting for you.

Check this example JSF:

    

    
        #{e.user.id}
    

Backed with this managed bean:

@Named(value = "userListState")
@SessionScoped
public class UserListState implements Serializable{
    private Map filterState = new HashMap();
    private List filteredValue;

    public UserListState() {
    }

    public void onFilterChange(FilterEvent filterEvent) {
        filterState = filterEvent.getFilters();
        filteredValue =(List) filterEvent.getData();
    }

    public String filterState(String column) {
        return filterState.get(column);
    }

    public List getFilteredValue() {
        return filteredValue;
    }

    public void setFilteredValue(List filteredValue) {
        this.filteredValue = filteredValue;
    }
}
