    accessing hidden field values in a SFSB

    Arbi Sookazian Master

      does the scope of the SFSB matter when you're trying to access hidden field values from a .xhtml page?

      I know that Seam defaults to conversation scope if you don't set it explicitly (which is the case in this SFSB) but does that affect retrieval of the hidden field values via the FacesMessage object as follows?:

      FacesContext fc = FacesContext.getCurrentInstance();
       Map map = fc.getExternalContext().getRequestParameterMap();
       String rowIndex = (String) map.get("rowIndex");


      here, rowIndex is the id of the <h:inputHidden> tag in the .xhtml. It's showing as null when I output it to the server.log.

      How do I access the value of this hidden variable? I know, I posted this in the Richfaces forum as well...

          I tried accessing the rowIndex, for example, in the SFSB via the SessionContext Seam object and that returned null as well...

            In your example, you would want to use a normal

            <input type="hidden" name="rowIndex" />
            


            rather then <h:inputHidden>

            or else change this

            (String) map.get("rowIndex");

            to the actual generated name of the field (something like formName:rowIndex).

            best,
            Dustin

              thx for reply. I tried the <input type="hidden" .../> as below, but the setter methods are still not being called for these hidden fields. The way I have to reference the hidden fields is different now (no a4jForm prepended to it).

              setNoteText() is being called ok.

                ok thx bro. your 2nd suggestion worked:

                FacesContext fc = FacesContext.getCurrentInstance();
                 Map map = fc.getExternalContext().getRequestParameterMap();
                 String rowIndex = (String) map.get("a4jForm:rowIndex");
                 log.info("rowIndex = " + rowIndex);
                 String colName = (String) map.get("a4jForm:colName");
                 log.info("colName = " + colName);
                 String siteId = (String) map.get("a4jForm:siteId");
                 log.info("siteId = " + siteId);
                 String employeeNumber = (String) map.get("a4jForm:employeeNumber");
                 log.info("employeeNumber = " + employeeNumber);
                


                the correct values were outputted in the log. this stuff is such a pain in the ass, wow....
