I have found a way using MyFaces Tomahawk's updateActionListener. Something
like:
| <h:form id="section_questions">
| <ul id="linkslist">
| <t:dataList value="#{sections}"
var="currentSection" layout="simple"
| rendered="#{not empty sections}"
id="dt1"
| rowIndexVar="sectionRowIndex">
| <li><h:outputText
value="#{currentSection.sectionLabel}" />
|
| <ul>
| <t:dataList
value="#{currentSection.questions}"
| var="currentQuestion"
layout="simple"
|
rowIndexVar="questionRowIndex"
| rendered="#{not empty
currentSection.questions}" id="dt2">
| <li><h:commandLink
|
action="#{questionSelectionBean.selectQuestion}" id="cl1">
| <h:outputText
value="#{currentQuestion.questionLabel}" />
|
<t:updateActionListener id="sectionListener"
|
property="#{sectionSelectionBean.sectionRowIndex}"
|
value="#{sectionRowIndex}" />
|
|
<t:updateActionListener id="questionListener"
|
property="#{sectionSelectionBean.questionRowIndex}"
|
value="#{questionRowIndex}" />
|
| </h:commandLink></li>
| </t:dataList>
|
| </ul>
| </li>
| </t:dataList>
|
| </ul>
| </h:form>
Unfortunately the solution forces me to use a form/commandLink action. I get
the following exception when trying to use the s:link.

I am using a TomahawkUpdateActionListenerHandler as written by Andrew Robinson
(http://www.mail-archive.com/[email protected]/msg09735.html)
Any ideas ? Ideally I would like to work with s:link and not have the whole
form with javascript as generated by the commandLink.
Regards
Louis
