<h:column>
<f:facet name="header" >
<h:outputText value="#"/>
</f:facet>
<h:outputText value="#{loc.rowNum}"/>
</h:column>
</h:dataTable>
with class
@ManagedBean
public class OtsTableClass implements Serializable {
private List<OtsTableBodyClass> list;
...
}
and it works fine, but i need add delete button as table column
and i add
in jsf
<h:column>

<f:facet name="header">Action</f:facet>

<h:commandLink value="Delete" action="#{otsTableClass.deleteAction(loc)}" />

</h:column>
in class file
public String deleteAction(OtsTableBodyClass order) {

list.remove(order);
