problems with the logic:iterate tag

Hi !

I have a problem with the <logic:iterate > tag

the following piece of 'code' works ok=20
(so I know I=B4m doing nothing wrong on the Controller/Model side):

<jsp:useBean id=3D"item" scope=3D"page" class=3D"com.mycomp.SomeData"/>

<table>
<%=09
	Iterator it =3D
((Collection)session.getAttribute("someList")).iterator();
	while (it.hasNext()){
		pageContext.setAttribute("item",it.next());
%>
  <tr>
    <td align=3D"left">
      <bean:write name=3D"item" property=3D"name"/>
    </td>
    <td align=3D"left">
      <bean:write name=3D"item" property=3D"manager"/>
    </td>
    <td align=3D"left">
      <bean:write name=3D"item" property=3D"ID"/>
    </td>
  </tr>
<% }  %>
</table>

but what I really like to do is
(our web designer would appreciate it !):

<jsp:useBean id=3D"item" scope=3D"page" class=3D"com.mycomp.SomeData"/>

<table>
<logic:iterate id=3D"item" name=3D"someList">
  <tr>
    <td align=3D"left">
      <bean:write name=3D"item" property=3D"name"/>
    </td>
    <td align=3D"left">
      <bean:write name=3D"item" property=3D"manager"/>
    </td>
  </tr>
</logic:iterate>

but with the second approach the table is always empty...

am I too stupid to use the iterate tag ?
or is something else wrong with my approach ?


pleas help !

Could you submit your example as an attachment? In my mail reader at
least, some of the control characters were converted to ASCII, and it
is difficult to read.

Re: problems with the logic:iterate tag

Posted by "Craig R. McClanahan" <Cr...@eng.sun.com>.
There was a bug in the nightly build versions through early January -- the
<logic:iterate> tag was not exposing the variable name you specified with "id"
to the rest of the page.  This has been fixed, AFAIK.  Can you please try this
with a very recent nightly build?

For the record, where "someList" is a bean that implements Collection, the
following code should work correctly:

<table>
<logic:iterate id="item" name="someList">
  <tr>
    <td align="left">
      <bean:write name="item" property="name"/>
    </td>
    <td align="left">
      <bean:write name="item" property="manager"/>
    </td>
  </tr>
</logic:iterate>
