Have you checked to make sure there are no validation errors?

Hi,
I have managed to workout with dataTable now; thank you. But, I have a
question about ValueChage event.
I have the following snapshot:
<h:selectOneMenu value="#{applicationProcess.courseTitle}"
onChange="submit();"
valueChangeListener="applicationProcess.changeApplicationList"
immediate="true">
<f:selectItems value="#{applicationProcess.courses}"/>
</h:selectOneMenu>
<t:dataTable
id="applicantsData"
styleClass="scrollerTable"
headerClass="standardTable_Header"
footerClass="standardTable_Header"
rowClasses="standardTable_Row1,standardTable_Row2"
columnClasses="standardTable_Column,standardTable_ColumnCentered,standardTable_Column"
var="applications"
value="#{applicationProcess.applications}"
border="1"
preserveDataModel="false">
<h:column>
<f:facet name="header"><h:outputText value="Selected"/></f:facet>
<t:selectBooleanCheckbox value="#{applicationProcess.selected}"/>
</h:column>
…..
……
In the above, changeApplicationList (value change method) changes the
list of applications list that is used by dataTable to display
applications. The following is the snapshot of my
changeApplicationList method (ValueChangeEvent):
String course=(String) event.getNewValue();
java.util.ArrayList list=new java.util.ArrayList();
while (result.hasNext()){
fill list with application….
----
}
}
this.setApplications(list);
}
}
My question is what triggers to render/re-render dataTable when value
is change in <SelectOnMenu>? Mine is not working.
Thanks,
Damar

Well yeah, though he probably wants check boxes, to be able to select
several at once. In that case, you can have a dataTable column like:
<h:column>
<f:facet name="header"><h:outputText value="Selected"/></f:facet>
<t:selectBooleanCheckbox value="#{data.selected}"/>
</h:column>
