      From the mailing list:


      I wrote a simple pager component but one parameter (currentPage)
      is not updated in a second request.

      In the template I have the following:

      <t:pager t:numberOfPages="$




      ... some other attributes ... />

      In the page class this currentPage accessor:

      public int getCurrentPage()

      { return _currentPage; }

      which is an int and has the correct values in all requests.

      The pager component contains this currentPage property

      @Parameter(required = true, defaultPrefix="prop")
      private Integer _currentPage;

      which is used in

      boolean beginRender( MarkupWriter writer )

      which returns false (no other render methods, no template).

      When I debug the code I see, that the first time, the _currentPage is
      accessed, the pages getCurrentPage method is invoked.
      In all subsequent page requests, the value of the first request is
      still stored and not updated.

      What am I doing wrong, or should T5 behave differently?

      Do I have to take any action to unbind/uncache/reset the currentPage
      property in the pager component?

      Thanx && cheers,

      This made my think that the binding for expansions may indicate the value is cacheable, when it is not.
