Command link / button action is not taking place if i use it in iterator.

Question

Hi,
I am new to ADF, i am facing 1 issue while implementing ADF mobile browser application.
Issue: command link / button action is not taking place if i use it in iterator. its just refreshing the page it self and displaying as no records.
Scenario is i am populating the search results in results page from search page using iterator, i want to get the complete details in different page (results page -> details page) .
I have tried in different ways.like
case1:
<tr:panelGroupLayout id="pgl2" layout="vertical" styleClass="af_m_panelBase">
<tr:panelHeader text="#{classviewBundle.SEARCH_RESULTS}" id="ph1"/>
<tr:iterator id="i1" value="#{bindings.SubjectVO1.collectionModel}" var="subject"
varStatus="subIndx" rows="100">
<tr:panelBox text="#{subject.Subject} #{subject.CatalogNbr} - #{subject.CourseTitleLong}"
styleClass="af_m_listingPrimaryDetails" id="pb1">
<f:facet name="toolbar"/>
<tr:table var="ssrClass" rowBandingInterval="1" id="t1" value="#{subject.children}"
varStatus="clsIndx" rowSelection="none"
binding="#{SessionBean.subjectTable}" verticalGridVisible="true"
emptyText="No Records" width="100%">
<tr:column id="c9" sortable="false" styleClass="width:100%">
<*tr:commandLink text="Section: #{ssrClass.ClassSection}-#{ssrClass.SsrComponentLovDescr} (#{ssrClass.ClassNbr})"*
id="commandLink2" styleClass="af_m_listingLink"
*action="#{pageFlowScope.BackingBean.searchaction}"></tr:commandLink>*
//remaining code
in this case commandlink action is not able to invoke serachaction() method
case 2:
<tr:commandLink text="Section: #{ssrClass.ClassSection}-#{ssrClass.SsrComponentLovDescr} (#{ssrClass.ClassNbr})"
id="commandLink2" styleClass="af_m_listingLink"
action="classdetails}"></tr:commandLink>
in this case its not able to navigate to classdetails page.
I gave correct navigation cases and rules in taskflow,but its working fine when the command link is out of iterator only.
i tried with actionlistener too.. but no use.. please help me out of this problem .
*Update to issue:*
The actual issue is when i use command link/button in an table/iterator whose parent tag is another iterator then the action is not taking place.
the structer of my code is
< iterator1>
#command link action1
< iterator2>
#command link action2
</ iterator2>
< /iterator1>
#command link action1 is working but "#command link action2" is not...
Thanks
Shyam

Answer 1

Hi,
To solve my problem I used a af:foreach instead.
<af:forEach items="#{viewScope.DataBySubjectServiceBean.toArray}" var="text">
<af:commandLink text="#{text.IndTextEn}" action="indicator-selected" id="cl1">
<af:setActionListener from="#{text.IndCode}" to="#{pageFlowScope.IndicatorCodeParam}" />
</af:commandLink>
</af:forEach>
By the way you need to convert the iterator to an Array using a ManagedBean.
public Object[] toArray() {
CollectionModel cm = (CollectionModel) getEL("#{bindings.TView1.collectionModel}");
indicators = new Object[cm.getRowCount()];
for(int i=0;i<cm.getRowCount();i++){
indicators[i] = cm.getRowData(i);
return indicators;
public static Object getEL(String expr) {
FacesContext fc = FacesContext.getCurrentInstance();
return fc.getApplication().evaluateExpressionGet(fc,expr,Object.class);
Hope that helps-

Add getEL Method
