DirectLink from within ForEach

Hi all,

Maybe I'm just missing something obvious, but if so, please refresh me. 
I'm rendering a table using a Foreach.  (I've mailed Mindbridge a couple
of months ago, and after looking at the details he suggested that this
is not a job for Contrib:table).

After doing a couple of these tables, I implemented a spreadsheet like
structure where I can fill in my values, set alignment, formats, etc,
and then spool it into a list for the ForEach.  Now I want to make some
of the cells (or values) clickable.  The problem is I want to do it from
the Java side, without changing the HTML.  So I want to do
cell.setClickable(id)
and this should then render a Directlink with the Id as the parameter. 
Is this at all possible, and how should I go about it?

I include the ForEach subset of the html file for reference below.

Thanks
reinier

<span jwcid="@Foreach" source="ognl:arrayRows" value="ognl:row">
<tr>
    <span jwcid="@Foreach" source="ognl:row" value="ognl:cell">
	<td jwcid="@Any" element="td" colspan="ognl:cell.colSpan"
class="ognl:cell.style">
		<span jwcid="@Insert" value="ognl:cell.contents"/>
	</td>
    </span>
</tr>
</span>

Thanx a million, Harish!  That worked perfectly, and it was a small
change.  Exactly what I was looking for.

I don't think you can do it unless you either override Insert with a custom component or wrap it 
with one of the link components. Why can't you always wrap it with a link component and disable it 
if you don't want a link?
