VALIDATION IN RADIO BUTTONS

Question

Hi every body ,
Is it possible validate to different radio button groups ?
Here is my JSF code :
<h:selectOneRadio
    id="radio1"  
    layout="pageDirection"
    immediate ="true"
    value="#{multiSiteBacking.radio1Value}"
    valueChangeListener="#{multiSiteBacking.radio1Action}"
    required="true">
<f:selectItem  itemLabel="Radio1" itemValue="4" />
<a4j:support event="onclick" reRender="form" />
</h:selectOneRadio>
<h:selectOneRadio
    id="radio2"  
    layout="pageDirection"
    immediate ="true"
    value="#{multiSiteBacking.radio2Value}"
    valueChangeListener="#{multiSiteBacking.radio2Action}"
    required="true">
<f:selectItem  itemLabel="Radio2" itemValue="4" />
<a4j:support event="onclick" reRender="form" />
</h:selectOneRadio>Here , when I am, clicking the Radio1 / Radio2 the validation of Radio2/Radio1 should be false .
Is it possible assiging validation dynamically ?
Thanks,
SB

Thanks again ,
I have implimented ajaxSingle="true" and immediate="true" in my app , but it is giving a different problem.
When user clicking the radio1 the radio2's value should be null & exactly opposite for radio2.For that reason am using a small code something like this in radio1 and radio2's valueChangeListener :
PhaseId phaseId = valueChangeEvent.getPhaseId();
              if (phaseId.equals(PhaseId.ANY_PHASE))
                   valueChangeEvent.setPhaseId(PhaseId.UPDATE_MODEL_VALUES);
                   valueChangeEvent.queue();
                  return;
//For radio1 action
//this.setRadio2Value(null);
//For radio2 action
//this.setRadio1Value(null); By this way I am able to achieve the check un-check functionality on my app.
My radio1 and radio2's check un-check functionality is going perfect , but I am not able to validate both radio buttons.If I commenting out all those PHASE related code then only it is working fine .But at the same time my check un-check functionality is not working.
Here is my small jsf view code :
<h:selectOneRadio
     id="radio1"
     layout="pageDirection"
     immediate ="true"
     value="#{multiSiteBacking.radio1Value}"
        valueChangeListener="#{multiSiteBacking.radio1Action}"
     required="#{multiSiteBacking.radio1ValueCheck}" >
<f:selectItem itemLabel="Radio1" itemValue="1" />
<a4j:support event="onclick" ajaxSingle="true" reRender="form" />
</h:selectOneRadio>
<h:message rendered="#{multiSiteBacking.radio1ValueCheck}" for="radio1" />     
<h:selectOneRadio
     id="radio2"
     layout="pageDirection"
     immediate ="true"
     value="#{multiSiteBacking.radio2Value}"
        valueChangeListener="#{multiSiteBacking.radio2Action}"
     required="#{multiSiteBacking.radio2ValueCheck}" >
<f:selectItem itemLabel="Radio1" itemValue="1" />
<a4j:support event="onclick" ajaxSingle="true" reRender="form" />
</h:selectOneRadio>
<h:message rendered="#{multiSiteBacking.radio2ValueCheck}" for="radio2" />     Here is my backing bean code :
//For required fields:
private boolean radio1ValueCheck=true;
private boolean radio2ValueCheck=true;
//radio1 and radio2's value
private String radio1Value;
private String radio2Value;
//For radio1
public void radio1Action(ValueChangeEvent valueChangeEvent) throws Exception
       PhaseId phaseId = valueChangeEvent.getPhaseId();
     if (phaseId.equals(PhaseId.ANY_PHASE))
             valueChangeEvent.setPhaseId(PhaseId.UPDATE_MODEL_VALUES);
             valueChangeEvent.queue();
             return;
       this.setRadio2Value(null);
      this.radio1ValueCheck(false);
      this.radio2ValueCheck(false);
//For radio2     
public void radio2Action(ValueChangeEvent valueChangeEvent) throws Exception
        PhaseId phaseId = valueChangeEvent.getPhaseId();
     if (phaseId.equals(PhaseId.ANY_PHASE))
             valueChangeEvent.setPhaseId(PhaseId.UPDATE_MODEL_VALUES);
             valueChangeEvent.queue();
             return;
        this.setRadio1Value(null);
        this.radio1ValueCheck(false);
        this.radio2ValueCheck(false);
//Getter and setter are here....This is my problem.
If you need more explanation please let me know .
