Hi,

I am unable to display page message in my vf page.

the following is the code.

<apex:page controller=" xyz">

<apex:outputPanel id=panelid>

</pageMessages>

<apex:commandlink action="{reference}" value=" save and send" rerender="panelid">

</apex:outputPanel>

 </apex:page

-----------------------------------------------------------------------------------------------

controller code

public pagerefernce reference(){

       set<string>  emails = new set<string>();
        /checkValid EMails
       for(String e :emails){
        checkEmail(e);
        if(isValid(e)){
        system.debug('check email is not completed calledcccccc');  
        ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR,'Check your email');
         ApexPages.addMessage(myMsg);  
        }
       }
       
       if(vEmails.size()==eMessage.size()){
          ApexPages.addmessage(new ApexPages.message(ApexPages.severity.Error, 'At least one email is mandatory'));
       }

     
       
        for(ApexPages.Message message : ApexPages.getMessages()){
        System.debug(message.getComponentLabel() + ' : ' + message.getSummary());
        }
        
      return null;
    }
    
    //validate Email
  
    
    public  boolean isValid(String email){

// Regular Expression for email
String emailRegex =  '^[_A-Za-z0-9-+]+(\\.[_A-Za-z0-9-+]+)*@[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$';

Pattern MyPattern = Pattern.compile(emailRegex);

// then instantiate a new Matcher object ”MyMatcher”
Matcher MyMatcher = MyPattern.matcher(email);

if (!MyMatcher.matches()) {
return true;
}else{
return false;
}
}

Thanks & Regards
