[ashokmignite]

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>
