Hello all,
I am having some difficulties with t:DataTable and
t:commandSortHeader: they do not sort my data. I have a bean named
"expList" saved in the session, and I have programmed a sort method
following the MyFaces examples. But I found whenever I click the
command sort header, the "sort" function is simply not called.
My steps to uses the sortable table are:
1. define a List data member called list in my expList class/object
2. define a sort function to sort the list based on sort solumn and
ascending attribute
3. populate the expList and save it in the session;
My JSP is like the following:
<h:form>
<t:dataTable id="data" var="exp"
value="#{expList.list}"
sortColumn="#{expList.sort}"
sortAscending="#{expList.ascending}"
preserveDataModel="true"
preserveSort="true">
<h:column>
<f:facet name="header">
<t:commandSortHeader columnName="id"
arrow="true"
immediate="false">
<h:outputText value="id" />
</t:commandSortHeader>
</f:facet>
<h:outputText value="#{exp.id}" />
</h:column>
<h:column>
<f:facet name="header">
<t:commandSortHeader
columnName="expDesign" arrow="true"
immediate="false">
<h:outputText value="design" />
</t:commandSortHeader>
</f:facet>
<h:outputText value="#{exp.expDesign}" />
</h:column>
</t:dataTable>
</h:form>
Any problems with my understanding of t:Datatable and t:commandSortHead?
Thanks!
