Try something like this;
<logic:iterate name="formActionForm" property="fields" indexId="index"
id="field">
<tr>
<td>
<html:text property='<%="fields["+index.intValue()+"]"%>'/>
</td>
<td>
<html:select property='<%=fields["+index.intValue()+"]%>'>
<html:optionsCollection name="definitionFields"/>
</html:select>
</td>
/// similarly for other fields
</tr>
</logic:iterate>
The trick is to start from the form level and adjusting the property
accordingly.
