I want to show a list of data to the user. My problem is that if I set the 'rendered' flag of <h

utputText> to 'false' just the header of the table appears (not the whole information) ... and if I set it to 'true', the page throws an exception.

Here are the codes I have written so far :

This is a part of my jsp code:

<f:view>
                                            <body> 
                                                
                                              <h:form>
            <h :D ataTable value="#{tableData.userLogs}" var="userLogs">
                         
            <h:column>
                <f:facet name="header">
                    <h :o utputText value="#{msgs.lastColumnHeader}" 
                                  style="font-weight: bold"/>   
                </f:facet>
               
                <h :o utputText value="#{userLogs.userlog}" rendered="true"/>
            </h:column>
            
            <h:column></h:column><h:column></h:column><h:column></h:column>
            <h:column></h:column><h:column></h:column><h:column></h:column>
            
               <h:column>
                  <f:facet name="header">
                     <h :o utputText value="#{msgs.firstColumnHeader}" 
                        style="font-weight: bold"/>
                  </f:facet>
                 
                  <h :o utputText value="#{userLogs.datelog}" rendered="true"/>
               </h:column>
                 
            </h :D ataTable>
         </h:form>
                                             
                                            </body>
</f:view>

Here is the source code of TableData.java :

This part has been taken from faces-config.xml :

& this is my bean class :

please kindly help me,
Thank you,
Maryam

You're getting an exception with the rendered attribute because when you set it to true, it actually executes the methods of the bean, and there you have the problem.
I didn't look closely at your code, can you post the exception?
Setting rendered =true for the different components will help you to isolate where the problem lies

My problem is over now...

I changed the first code to the second (look at the names of the setters and getters) :

Yep, the exception message tells everything:
"Error getting property 'userlog' from bean of type beanPack.UserLogs"
"userlogs" in bean notation is "getUserlogs" and in your bean you had "getUserLogs"
Glad you had it working now
