Making a rich:column dynamic using rendered

[kimda]

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....

`

<rich:dataTable rendered="#{growthParametersPrintList.size ne 0}"
                            id="growthParametersList"
                            rowKeyVar="rowKey"
                            value="#{growthParametersPrintList}"
                            var="entry">             
                                <f:facet name="header">
                                    <rich:columnGroup>
                                      
                                  
                                    ...

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

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>
