This is a form in which i have provided validation using constraints
but how to provide the same validations using a controller

package com.genapt.thinktank.controller.product;

import org.zkoss.zk.ui.Component;
import org.zkoss.zk.ui.util.Clients;
import org.zkoss.zk.ui.util.GenericForwardComposer;
import org.zkoss.zul.Intbox;
import org.zkoss.zul.Textbox;

public class CustomernewDivIDViewCtrl extends GenericForwardComposer {

private static final long serialVersionUID = 1L;
private Textbox customer_customername_Textbox_ID;
private Textbox customer_contactperson_Textbox_ID;
private Textbox customer_email1_Textbox_ID;
private Intbox customer_mobileno_intbox_ID;

public void doAfterCompose(Component comp) throws Exception {
super.doAfterCompose(comp);
}
public void constrint(){
customer_contactperson_Textbox_ID.setConstraint("//:Starting only characters are allowed");
}
public void constrint1(){

}
public void onClick$save_Button_ID() {
Clients.clearWrongValue(new Component[] {customer_customername_Textbox_ID,customer_contactperson_Textbox_ID,customer_mobileno_intbox_ID,customer_email1_Textbox_ID});

if(customer_customername_Textbox_ID.getValue() == "" ){
//customer_customername_Textbox_ID.setConstraint("//:Starting only characters are allowed");
Clients.wrongValue(customer_customername_Textbox_ID, "Customername cannot be emprty");
}
else if(customer_customername_Textbox_ID.getValue() != "//"){
Clients.wrongValue(customer_customername_Textbox_ID, "Stating only characters are allowed");
}

else if(customer_contactperson_Textbox_ID.getValue() == "" ){
//constrint();
Clients.wrongValue(customer_contactperson_Textbox_ID, "Contact cannot be emprty");
}
else if(customer_mobileno_intbox_ID.getValue() == null ){
Clients.wrongValue(customer_mobileno_intbox_ID, "Contact cannot be emprty");
}
else if(customer_email1_Textbox_ID.getValue() == "" ){
customer_email1_Textbox_ID.setConstraint("/[a-zA-Z0-9._\\-]+@[a-zA-Z0-9.\\-]+\\.{2,4}/:Eneter proper email Id");
Clients.wrongValue(customer_email1_Textbox_ID, "Email cannot be emprty");
}
}
}

i tried this but if i enter correct values also its not validating .its raising an error like alert box
so any one can guid eme regarding this issue
