    Making a rich:column dynamic using rendered

    Daniel Kim Newbie
      Hi,

      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}":
      java.lang.NullPointerException

      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....

          Sorry, it should be this...

          <!-- works ok )-->
            <h:outputText value="#{e:formatAge(thisPerson.personDob, entry.when)}" />
              </rich:column>
             .....
                                                                                    
          <!-- 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}" />
                                         
          </rich:column>
