Now i could load and fill the dataTable, but when i click in sort links nothing happens, i need set preserveDataModel="true" in order to get sorting working?2006/7/19, Catalin Kormos < [EMAIL PROTECTED]>:Yeah, it needs the header facet to be there, so looks like a bug. Could you open a Jira issue for this?
Thanks,

<t:dataTable
var="item"
value="#{bean.results}"
preserveDataModel="false"
renderedIfEmpty="false"
sortable="true"
sortColumn="#{bean.sortColumn}"
sortAscending="#{bean.sortAscending}"
preserveSort="true"
rows="10"
>
<t:column defaultSorted="true">
<f:facet name="header">
<h:outputText value="ID" />
</f:facet>
<h:outputText value="#{ item.id}" />
</t:column>
</t:dataTable>
and this bean:
public abstract class Bean
{
//Variaveis de uso interno do bean
private String keyword;
private String sortColumn = null;
private boolean sortAscending = true;
private List results;
...
getters and setters
...
public String search()
{
results = new ArrayList();
...
fill results ArrayList with some entity instances
...
}
}
