    Seam Mail Problem NPE

    Tony Herstell Master

      Fail to get my email working asynch (very hard to debug!) again (tried this many months ago with no luck but now on Seam 2.1.1.GA and RF 3.2.2.SR1).


      Looked again at my non-asynch mail and noticed that an image that should have been there (it used to be!) was no longer there!


      <p>
           <h:graphicImage url="#{basePath}/images/sec_logo_sm.gif" />
      </p>



      This USED to work... with basePath defined in components.xml:


      <!-- Utility bean called "basePath"that allows the pages to reference the basePath for resources
      Usage: <link rel="stylesheet" type="text/css" href="#{basePath}/xmlhttp/css/xp/xp.css" />
           -->
      <factory name="basePath"
         value="#{facesContext.externalContext.request.scheme}://#{facesContext.externalContext.request.serverName}:#{facesContext.externalContext.request.serverPort}#{facesContext.externalContext.request.contextPath}/" />
      



      Floundered in doco and found that adding urlBase into the m tag was supposed to help.. but it didn't...


      <m:message urlBase="#{basePath}">




      humm...


      Resported to:



      <p>
          <h:graphicImage url="http://www.selwynequestriancentre.co.nz/site/images/sec_logo_sm.gif" />
      </p>



      and this works again in non-asynch.



      aysnch still fails with NPE

      Question 1.
      Is this a bug (why would basepath no longer work seems wrong to be adding in a full url)?



      Question 2.
      Why would the asynch throw a NPE.. whats the difference?
