Can you pls post you code...

 

I tried very simple code and it works-

<apex:page controller="Example">
<apex:form>
  <apex:pageMessages></apex:pageMessages>
  </apex:form>
</apex:page>

 

public class Example
   {
        public Example()
        {
            ApexPages.addMessage(new ApexPages.message(ApexPages.severity.Error,'It will display Error.'));
        }     
   }

You need to have Message tag inside tag which rerenders after your event.

 

eg. if you want message on click of button save and on save button you are rerendering pageblock "ABC". Then message tag should be inside page block ABC.
