S2: OGNL, calling a function on the action with parameters

[Eric Nielsen]

I'm working on something a little bit like a data grid. However, while the current display is tabular, the data backing it isn't. As a result I can't use straight map notation to access the values to display.

The relevant portion of the jsp looks like

  <s:iterator value="competition.feeCategories" id="fee">
    <tr><th><s:property value="name" /></th></tr>
    <s:iterator value="competition.sessions" id="session">
      <tr>
        <td><s:property value="name" /></td>
     <s:iterator value="competition.deadlines" id="deadline">
            <td><s:property value="#session.getDisplayPrice(#deadline,#fee)" /></td> <!-- 1 -->
            <td><s:textfield name="sessionMap[%{#session.id}][%{#deadline.id}][%{#fee.id}]" 
                             value="%{getSessionMarkup(#session,#fee,#deadline).costDeltaInCents}" /></td>  <!-- 2-->
            <td>Studio Markup (%)</td>
          </s:iterator>
   </tr> 
     </s:iterator>
   </s:iterator>

The action looks like:

public class ConfigurePrices extends ExcursionBase {
public String execute() {
return SUCCESS;
}
public StudioSessionPrice getSessionMarkup(Session session, CompetitionDeadline deadline, FeeCategory fee) {
for (StudioSessionPrice ssp: excursion.getSessionPrices()) {
if (ssp.getUnderlyingCompetitionSession().getSession().equals(session) &&
ssp.getUnderlyingCompetitionSession().getDeadline().equals(deadline) &&
ssp.getUnderlyingCompetitionSession().getFeeCategory().equals(fee))
return ssp;    
}
StudioSessionPrice ssp = new StudioSessionPrice();
ssp.setExcursion(excursion);
ssp.setUnderlyingCompetitionSession(session.getCSPfor(deadline,fee));
ssp.setCostDeltaInCents(0L);
ssp.setDeltaInPercent(0.0F);
excursion.addSessionPrice(ssp);
excursionRepository.save(excursion);
return ssp;
}
}

EscursionBase implements ActionSupport; the jsp shown before is hooked up to the INPUT result of the action.

The line preceding the <!-- 1 --> works properly, so I thought I knew how to call functions with parameters in OGNL. The line around <!-- 2--> does not work. The breakpoint just inside the function is not hit. However there are no errors in the log. What am I missing?

OK, I've tried reformulating it to use straight maps and not a functional lookup. I've tried both OGNL and regular EL notations. None of them seem to work -- in all cases the function backing the map property is not invoked. I changed the logging from INFO to DEBUG, but nothing jumps out at me.

What should I be looking for in the log to see why the function isn't getting invoked? What else should I try?
