    Rerender on a birt report is losing page parameters values

    Busssard Buss Newbie

      I have a jsf 2.0 xtml page with a seam birt  tag  to render a report . Everything works on the first call, but when I'm trying to rerender the report the page and EL parameters are missing .

      This is my page fragment:

       

      <h:commandButton value="Test" onclick="alert('Test Button ');">
        <a:ajax event="click" render="grf1"  />
      </h:commandButton>       
      <h:panelGroup id="grf1" layout="block">
        <b:birt designType="embed"
        embeddable="true"
        resourceFolder="#{request.contextPath}/reports/"
               designName="/relatorios/reportfile.rptdesign"
               masterpage="true"
        <b:param name="constantParam" value="true" />
        <b:param name="ELParam" value="#{'true'}" />
        <b:param name="pageParam" value="#{myPageParam}" />
        </b:birt>
      </h:panelGroup>
      

       

      I created a script to log the parmeters values in report:

       

      java.lang.System.out.println("constantParam :"+params["constantParam"].value);
      java.lang.System.out.println("ELParam :"+params["ELParam"].value);
      java.lang.System.out.println("pageParam :"+params["pageParam"].value);
      

       

      And this is the output at normal call:

       

      constantParam :true
      ELParam :true
      pageParam :15
      

       

      And this is the output at rerender call:

      constantParam :true
      ELParam :
      pageParam :
      

       

      What is the right way to rerender a birt report with parameters?
