DataTable Sorting not working

[LFR]

Hello,

 

I have the following problem:
I have a page displaying a dataTable that can be modified by the users
(add/update/delete row) this works fine.
Now I tried to implement sortable headers on my table.
To do this I added the following properties
to the bean managing the table :

 

private String sort="ident";
private boolean ascending=false;

 

With their getters/setters

 

public String getSort(){}
public void setSort(String sortColumn){}
public boolean isAscending(){}
public void setAscending(boolean ascending) {}

 

I also modified my dataTable, adding the sortColum and sortAscending properties:
<x:dataTable
  var="art"
  binding="#{GabaritManager.articlesList}"
  value="#{GabaritManager.articles}"
  sortAscending="#{GabaritManager.sort}"
  sortColumn="#{GabaritManager.ascending}"
>
  <h:column>
    <f:facet name="header">
      <x:commandSortHeader columnName="ident" arrow="true">
        <h:outputText value="Ident"/>
      </x:commandSortHeader>
    </f:facet>
    <h:outputText value="#{art.ident}"/>
</h:column>
[...]

 

Finally I updated the method returning the table value to take the sorting into account
Now when i load the form i always have the following error:

 

2005-10-21 10:54:33,830 [http-8080-Processor23] ERROR org.apache.myfaces.renderkit.html.HtmlGridRenderer  - Exception while rendering children of panel-grid.
java.lang.ClassCastException
 at org.apache.myfaces.component.html.ext.HtmlDataTable.getSortColumn(HtmlDataTable.java:685)

 

I tried a lot of things but none worked (like changing the ascending property to String)

 

Btw, i'm using myfaces 1.0.9 (bundled with MyEclipseIDE)

 

Thanks for your help
