<apex:message> how to get it to work for specific fields?

Hi i was wondering could someone give me an example on how to get <apex:message> to work, for example i have field called contact name and want the error to be shown on that field.

  

 if(!IsDuplicateLink())
        {
            insert s;
        }
        else
        {
            Account dupe = [SELECT Id, Name FROM Account WHERE Id = :eId];
            
            ApexPages.Message dupeMsg = new ApexPages.Message(ApexPages.Severity.ERROR,
                 'Contact already exists in ' + dupe.Name);
                 
            ApexPages.addMessage(dupeMsg);
            drawError = true;
        }
        
     <apex:message for="conName"/>
     <apex:inputField id="conName" value="{!Contact.Name}"/>
 
for some reason this does not work?

for (Account a : Trigger.new) {
   if (a.name == 'bad') {
      a.name.addError('Bad name'); //will add an error to the account NAME field
   }
}

hmm but will this automatically add the error to my custom visualforce page? I am also having problems where i want my standard validation rules which are shown most at the field level, to be shown in my custom visualforce page?


KeithJKeithJ
Ah, you want it to work for underlying validation rules...
That, I have not done before. I would be curious to see how that is done.

that doesn't solve my problem, i want to show the error below a field like in standard pages that have validation rules.

If I understand what you are asking, where you asked, "I am also having problems where i want my standard validation rules
which are shown most at the field level, to be shown in my custom
visualforce page?", and you are using a standard controller, it should just work without using apex:message.  From the developer guide, 
 
If a user enters data on a Visualforce page that uses a standard controller, and that data causes a validation rule error, the error can be displayed on the Visualforcepage. If the validation rule error location is a field associated with an <apex:inputField> component, the error displays there. If the validation rule error location is set to the top of the page, use the <apex:pageMessages> or <apex:messages> component within the <apex:page> to display the error. 
 
If you are using a custom controller, it's a bit harder.  You have to catch the error in your controller.  See http://www.salesforce.com/us/developer/docs/pages/Content/pages_controller_validation.htm

If i use a standard controller and an extension controller does this still hold true?

Yes, your extension would try {} catch {} each DML operation and use addMessage() to place feedback on the page , in the location of the < apex : message > component

For the new ApexPages.Message object that is passed to the addMessage() method, how would a person associate the message with a particular field back on the VF page? I assume this needs to be done to display the error message with the appropriate <apex:message> component. I see that there is a Message.getComponentLabel() method, but I do not see in the docs a Message.setComponentLabel() method or a way to pass that to the ApexPages.Message contructor.
 
thanks,

I also have a problem to see apex:messages on Vf when using extensions and rendering action status:
 
VF:
 
<apex:page standardController="Object__c" extensions="CustumController" ><apex:messages />
<apex:pageBlock title="Data" >
	<apex:pageBlockButtons >
		<apex:commandButton value="Do something"  action="{!DoSomething}" rerender="status" status="Status" />
	</apex:pageBlockButtons>
<apex:actionStatus id="Status" startText="I'm doing something">
   <apex:facet name="start">
      <apex:outputtext > &nbsp;I'm doing something</apex:outputtext>
   </apex:facet>
   <apex:facet name="stop">
   </apex:facet>
</apex:actionStatus>
 
 It is working when I'm not using rerender="Status" Status="Status". Any Idea how to get Apexmessages when using actionStatus?
