Detect postback

[bashan]

Hi,

I would like to count forum entries every time they are seen by users.
I currently made the count in pages.xml:

  <page view-id="/entry.show.xhtml" action="#{forumEntryAction.countView()}">
  </page>

and bean:

  @RequestParameter
  private Integer entryId;

  @Create
  public void init()
  {
    if (entryId != null)
    {
      forumEntry = forumDAO.getForumEntry(entryId);
    }
    else
    {
      forumEntry = new ForumEntry();
    }
  }

  public void countView()
  {
    forumEntry.setViews(forumEntry.getViews() + 1);
    myDB.persist(forumEntry);    
  }

My problem is that, this page has ajax regions causing it to be re-rendered many times. I need to avoid the count on a postback (like ajax requests).

Is there a way to tell the action method not to be called on a postback?
Is there a way of detecting postback in Seam?
Is there a better way of doing what I want to achieve?

Thanks,
Guy.
