Title: How to detect which row in the table was klicked?

Hi all

I am a beginner in Cocoon and I try to do the following:

I have a search form which presents some results in a table. When i press a row in the table,
a detail page appears.

Actually i do something like this:
 
flow:
  // do search...
  var trxList = ...

  // show result form
  form.showForm("activityFollowup.form", {trxList:trxList});

 // get the selected row
 var id = form.submitId;

  // and display the detail page
 form.showForm("transactionDetail.form", {trx:trxList[id]});

In the form definition I create the table like this:

<jx:set var="counter" value="#{0}"/>

<table id="resultTable" width="100%" border="0" cellspacing="0">
  <jx:forEach var="item" items="${trxList}">
    <jx:set var="counter" value="#{1 + $counter}"/>

    <tr>
      <td>
        // represent the text as submit link to go back in the flow
        <input class="submitLink" type="submit" id="${counter}" value="${item.trxDate} />
      </td>
       .
       .
       .
    </tr>
  </jx:forEach>
</table>

Back in the flowscript, unfortunately the submitId is null. How can I detect
on which row the user klicked?
