Question

Listing a id of items in a table
which looks like:

<g:sortableColumn style="width: 20px" property="id" title="${message(code: 'packet.id.label', default: 'Id')}" />


<g:each in="${packetInstanceList}" status="i" var="packetInstance">
          <tr class="${(i % 2) == 0 ? 'odd' : 'even'}">

             <td><g:link controller="packet" action="show"  id="${packetInstance.id}">${fieldValue(bean: packetInstance, field: "id")}
</g:link></td>

Shows me id of the items from domain packet.

I would like to turn them into a count,
which starts from 1, independent from id number.

Answer 1

Try:

<g:each in="${packetInstanceList}" status="i" var="packetInstance">
  <tr class="${(i % 2) == 0 ? 'odd' : 'even'}">
    <td>
      <g:link controller="packet" action="show"  id="${packetInstance.id}">${i + 1}</g:link> 
    </td>
