      HI FRIENDS THIS IS USEFUL TO ALL SEAM USERS !


      JSF CODE:


      <s:decorate id="minScoreField" template="layout/edit.xhtml">
                           <ui:define name="label">Minimum Score: </ui:define>
                           <h:inputText id="minScore"
                                  required="true"
                                  styleClass="normalFont"
                                     value="#{assesmentConfigHome.instance.minScore}"
                                      size="12" >                                           
                                    
                                      <f:validateDoubleRange minimum="0" maximum="9" />
                                                              
                                       
                                     
                          <a:support event="onblur" reRender="minScoreField" bypassUpdates="true" ajaxSingle="true"/>
                           </h:inputText>
                          
                       </s:decorate>
           
                       <s:decorate id="maxScoreField" template="layout/edit.xhtml">
                           <ui:define name="label">Maximum Score: </ui:define>
                           <h:inputText id="maxScore"
                                  required="true"
                                  styleClass="normalFont"
                                     value="#{assesmentConfigHome.instance.maxScore}"
                                      size="12"  >
                                       <f:validator validatorId="memberValidator" />
                                      <f:attribute  name="passwordId"  value="assesmentConfig:minScoreField:minScore" />
                                     
                                    
                                       <f:validateDoubleRange minimum="0" maximum="9" />
                                      
                      <a:support event="onblur" reRender="maxScoreField" bypassUpdates="true" ajaxSingle="true"/>  
                           </h:inputText>



      VALIDATOR BEAN CODE:


      public class MemberValidator implements Validator {
           
           
           public void validate(FacesContext context, UIComponent component, Object value)
                     throws ValidatorException {
                
                
                // Obtain the client ID of the first password field from f:attribute.
              String passwordId = (String) component.getAttributes().get("passwordId");
             
              // Find the actual JSF component for the client ID.
              UIInput passwordInput = (UIInput) context.getViewRoot().findComponent(passwordId);

              // Get its value, the entered password of the first field.
                    java.math.BigDecimal mins1 = (java.math.BigDecimal) passwordInput.getValue();
            
             

              // Cast the value of the entered password of the second field back to String.
                //  java.math.BigDecimal maxs1=new BigDecimal(0.0);
              java.math.BigDecimal   maxs1 = (java.math.BigDecimal) value;
            
       
              if ( (mins1!= null) && (maxs1 != null)&& (mins1.doubleValue()>maxs1.doubleValue())) {
                throw new ValidatorException(new FacesMessage("Minimum score must be smaller than Maximum score" ) );
              }

              // You can even validate the minimum password length here and throw accordingly.
              // Or, if you're smart, calculate the password strength and throw accordingly ;)
           }

           
                
      }


      ADD FOLLOWING CODE IN FACE-CONFIG.XML

      <validator-id>memberValidator</validator-id>
        <validator-class>org.domain.pixel.validators.MemberValidator</validator-class>
      </validator>
