Subject c:forEach issue in JSF 2
Date Wed, 01 Jul 2015 07:42:32 GMT
Hi,

I am upgrading my application from JSF 1.2 to JSF 2.

I am trying a below simple forEach tag but it not showing anything inside
the loop.

<table
    id="tab${sectionId}"
  border="0"
  cellpadding="0"
  cellspacing="0"
  width="100%"
  class="listingTable"
>
<c:forEach
var="row"
rowStatus="index"
items="#{bean.department.userActivities}"
>
            <tr>
                <td>
                    test
                 </td>
             </tr>
</c:forEach>
</table>

The value test is not showing up. Has the c:forEach implementaion changed?

I tried replacing <c:forEach> with <t:dataList> but <t:dataList> has some
other issue. It is rendering the content inside it. But if I have a
component inside <t:dataList>, I am not able to assign a backing bean value
as ID of the component. Example is as below

<table
id="tab${sectionId}"
border="0"
cellpadding="0"
cellspacing="0"
width="100%"
class="listingTable"
>
<t:dataList
var="row"
rowIndexVar="index"
value="#{bean.department.userActivities}"
>
<h:column>
<h:outputText id="#{row.activityCode}">test1</h:outputText>
</h:column>
</t:dataList>
</table>

So, with <t:dataList>. I am not able to assign backing bean property as ID
of the component. I am receiving the error
"java.lang.IllegalArgumentException: component identifier must not be a
zero-length String "

Can anyone please help me in understanding as to why the c:forEach tag is
not working. I have huge code which is using forEach tag. With upgrade, I
will have to remove every forEach if it is no more supported in JSF2 :(

Thanks in advance!
