public abstract class AbstractHtmlCommandSortHeader
extends org.apache.myfaces.component.html.ext.HtmlCommandLink

Clickable sort column header. Must be nested inside an extended data_table tag. This tag is derived from the standard command_link tag and has the additional attributes columnName and arrow. Note: In contrast to normal command links, the default for the "immediate" attribute is "true". This is desirable as it avoids validating all input fields in the enclosing form when the column sort order changes. HOWEVER when the table contains input components "immediate" must be set to false; otherwise input fields will render blank after a sort, or will show their old values (ie will not appear to sort though output fields in the table will sort) when sort ordering is changed. Unless otherwise specified, all attributes accept static values or EL expressions.

public void broadcast(javax.faces.event.FacesEvent event)

broadcast in class javax.faces.component.UICommand


public org.apache.myfaces.component.html.ext.HtmlDataTable findParentDataTable()


public abstract String getColumnName()
The name of this column. This name must uniquely identify this column among all other (sortable) columns in the same data_table. The sortColumn attribute of the embedding data_table reflects the current sort column (see extended data_table).


public abstract String getPropertyName()
The property name associated with this column. This name must be one of the properties of the row object by which the sorting should be performed. The sortProperty attribute of the embedding data_table reflects the current sort property (see extended data_table).


public abstract boolean isArrow()
Indicates whether an arrow, that shows the sort direction should be rendered. Default: false
