[S2] Display Tag? (2.0.11)

[Jake Robb]

I've used DisplayTag with S1 before, with excellent results.  I'm also
using it in S2 in a few cases, and it's working fine.

However, now I want to use it to render a form.  Each row in the table
will contain a couple of input tags, and the table as a whole represents
a single List on my action.

Without DisplayTag, I can accomplish that as follows:

  <s:iterator value="rules" status="status" id="rule">
    <div class="resultRow${status.odd ? ' highlight' : ''}">
      <div class="name">
        <s:property value="name" />
      </div>
      <div class="value">
        <s:textfield name="%{'rules['+#status.index+'].value'}" label=""
size="90" />
      </div>
    </div>
  </s:iterator>


I converted the code above as follows:

  <display:table htmlId="rulesTable" list="rules" id="rule">
    <display:column title="Rule Name">
      <s:property value="name" />
    </display:column>
    <display:column title="Rule Name">
      <s:textfield name="rules[rule_rowNum].value" label="" size="90" />
    </display:column>
  </display:table>


But that didn't work, because DisplayTag doesn't push rule_rowNum onto
the stack.  So I added a push tag:

  <display:table htmlId="rulesTable" list="rules" id="rule">
    <s:push value="<%= rule_rowNum.toString() %>" id="rowNum"/>
    <display:column title="Rule Name">
      <s:property value="name" />
    </display:column>
    <display:column title="Rule Name">
      <s:textfield name="rules[rowNum].value" size="90" />
    </display:column>
  </display:table>


Then I discovered that s:push doesn't accept runtime expressions, just
like everything else in 2.0.11.

So, how do I accomplish this?  I guess I could keep it the old way, but
I'd really rather be consistent.
