    Making a rich:column dynamic using rendered

    Daniel Kim Newbie

      I am trying to make rich column dynamic and trying to rendered property.
      Plz see the below code.

      entry.when is not null for this line
      '<h:outputText value="#{e:formatAge(thisPerson.personDob, entry.when)}" />'

      however, "entry.when " is null for this line
      '<rich:column rendered="#{e:getAgeInMonthsAtDate(thisPerson.personDob, entry.when)  lt  60}">'

      and I get this error.
      javax.el.ELException: /META-INF/facelets/print.xhtml @136,119
      rendered="#{e:getAgeInMonthsAtDate(thisPerson.personDob, entry.when) lt 60}":

      I check this func and see this:

      Caused by: java.lang.NullPointerException
      at java.util.Calendar.setTime(Calendar.java:1075)
      at diana.ehr.el.StringFunctions.getAgeInMonthsAtDate(StringFunctions.java:152)

      so, I know "entry.when " is null for rendered property.

      I know entry.when is not null always and this happens even when size of growthParametersPrintList is 1.

      thanks in advance....



      <rich:dataTable rendered="#{growthParametersPrintList.size ne 0}"
                                      <f:facet name="header">

                                              <!-- works ok , causing NullPointerException (entry.when is null)-->
                                              <h:outputText value="#{e:formatAge(thisPerson.personDob, entry.when)}" />
                                                  <!-- doesn't work  -->
                                       <rich:column rendered="#{e:getAgeInMonthsAtDate(thisPerson.personDob, entry.when)  lt  60}">
                                          <h:outputText value="#{entry.wtHtPercentile}" />

          Sorry, it should be this...

          <!-- works ok )-->
            <h:outputText value="#{e:formatAge(thisPerson.personDob, entry.when)}" />
          <!-- doesn't work , causing NullPointerException (entry.when is null -->
          <rich:column rendered="#{e:getAgeInMonthsAtDate(thisPerson.personDob, entry.when) lt 60}">
               <h:outputText value="#{entry.wtHtPercentile}" />
