t:dataTable DataModel must exist when using sorting?
Hi guys,
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:

Re: t:dataTable DataModel must exist when using sorting?

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}"

sortable="true"
sortColumn="#{bean.sortColumn}"
sortAscending="#{bean.sortAscending}"

<f:facet name="header">
<h:outputText value="ID" />
</f:facet>
<h:outputText value="#{ item.id}" />
</t:column>

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
...
}
}
