Hi,

I have to display a table with data to be shown taken from a ArrayList. It
has few columns like Title, Creator, Created On, Bring down, Undo Bring
down, Undo Edit. The last three are supposed to just have checkboxes. There
should be a 'Check All' option also which will be in the Table header.
[Note : code and exception below]
We have a menu [tree] which has some categories. On clicking of any category
the respective table [as above] will be shown. For some categories the table
is displayed fine. But for some others its is not and it is giving the
following exception. Any idea?

The code I am trying to use for checkbox is this
-----------------------------------
        <% String temp="Bring Down"+"<input type=checkbox name=BDNAll
onclick="+"\"javascript:checkAllNew(document.itemsForm, this,"+statusCode
+")\">";%>
        <display:column class="tablecontent" align="center" title="<%=temp%>">
        <%
if(Constants.LIVE_ITEMS.equals(((ContentItem)contentItem).getPubStatus()))
{ %>
             <input type="checkbox" name="BDN"

value="<%=(((ContentItem)contentItem).getId())%><%=Constants.SEPERATOR%><%=(
((ContentItem)
contentItem).getVersionId())%><%=Constants.SEPERATOR%><%=(((ContentItem)cont
entItem).getName())%>

<%=Constants.SEPERATOR%><%=(((ContentItem)contentItem).getRequestor())%><%=C
onstants.SEPERATOR%><%=                (((ContentItem)contentItem).getProvider())%>"/>
             <%}else {%>
             &nbsp;
        <% } %>
           </display:column>
----------------------------------
