    Selected Entity from dataTable is not handed over to Backing Bean

    Jan Vandam Newbie

      Hello,


      I am new to Seam and run into a problem. I have a working application with a page containing a dataTable:


      <rich:dataTable id="outputFileList"
           var="_outputFile"
           value="#{outputFileList.resultList}"
           rendered="#{not empty outputFileList.resultList}">
      



      Every line in the table has a link:




                  <s:link action="#{outputFileAction.downloadOutputFile(_outputFile)}"
                           value="Download"
                     propagation="none"
                              id="outputFileDownload"
                        rendered="#{empty from}">
                  </s:link>
              </rich:column>
          </rich:dataTable>
      




      Obviously I have a backing bean OutputFileAction with a method downloadOutputFile:




           public String downloadOutputFile(OutputFile outputFile) {
              setOutputFile(outputFile);
      
                String returnFlag = "IMATSuccessfull";
                logger.info("****** start output file download - filename = " + outputFile.getFilename());
                return returnFlag;
           }
      




      The method is called indeed, however the parameter outputFile is null.


      Why is that?


      The class has a field:



           @In(create=true)
           OutputFileHome outputFileHome;
      



      What is wrong or missing?
      Thanks in advance for any suggestions.
