2006/7/19, Catalin Kormos <
[EMAIL PROTECTED]>:
You don't need preserveDataModel="true" to make the auto sorting work. What you could do is set the sort properties manualy for each column, maybe the dataTable wasn't enable to determine them right.

Could you open a Jira issue for this?
Thanks,

I have a dataTable that only filled after execute a method on my bean, this table uses sorting using this code:
<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
...
}
}
but when i load the page i get this error:
