Getting the selected row (selected using radio button in dataTable)

Question

I have problem getting the selected row.
If not mistaken, the way used in BalusC's website sets the value to the backing bean using the valueChangeListener.
Can I set the value to the DTO instead?
using something like
private boolean selected;
public void setSelectedItem(ValueChangeEvent e){
this.selected = true;
}  If i use this way it throws NoSuchMethodException. I have no idea why. I did this for the checkbox and it works fine. I don't know why it doesn't work for radio buttons.

The DataTable is below :
<h:panelGrid columns="1" columnClasses="table_align">
          <t:dataTable id="table1" value="#{sysMgrBean.locationList}"
               var="location" rows="5" styleClass="table" headerClass="tableHeader"
               rowClasses="tableRowOdd, tableRowEven" width="500">
               <t:column>
                    <f:facet name="header">
                         <h:outputText styleClass="lbl" value="#{lbl['no']}" />
                    </f:facet>
                    <h:outputText value="#{location.id}" />
               </t:column>
               <t:column>
                    <f:facet name="header">
                         <h:outputText styleClass="lbl" value="#{lbl['slct']}" />
                    </f:facet>
                    <h:selectOneRadio  value="#{location.selected}"
                         onfocus="dataTableSelectOneRadio(this);"
                         onclick="enableInput(this.form,this)" valueChangeListener="#{location.setSelectedItem}">
                         <f:selectItem itemValue="" value="true" />
                    </h:selectOneRadio>
               </t:column>
               <t:column>
                    <f:facet name="header">
                         <h:outputText styleClass="lbl" value="#{lbl['cd']}" />
                    </f:facet>
                    <h:outputText value="#{location.loccd}" />
               </t:column>
               <t:column>
                    <f:facet name="header">
                         <h:outputText styleClass="lbl" value="#{lbl['desc']}" />
                    </f:facet>
                    <h:inputText id="Description" value="#{location.descr}" disabled="#{location.disabled}" />
               </t:column>
          </t:dataTable>In the DTO :
private boolean selected;
public void setSelectedItem(ValueChangeEvent e){
this.selected = true;
}
