rich:columns, rich:column visible attribute : show/hide colu

[apg9595]

I have searched through google for more elaborate way of using this particular attribute to show/hide columns in a dynamic manner

Richfaces 3.3.2
Jboss 4.3 EAP
Linux/Windows/Solaris
Myfaces 1.2.5


Here is my code

<rich:scrollableDataTable
frozenColCount="# {itemController.grid.frozenColCount}"
height="500px"
width="1200px"
id="grid"
rows="40"
value="#{itemController.grid.rows}" var="row"
rowKeyVar="rowKey"
hideWhenScrolling="true"
rowClasses="row1,row2"
>
<rich:columns value="#{itemController.grid.columns}"
var="column"
index="ind" id="dynaColumn"
sortable="false"
visible="#{column.visible}"
>
<f:facet name="header" >
<h:outputText value="#{column.name}"
styleClass="richDataTableHeaderFont"/>
</f:facet>

<a4j:commandLink id="expandCollapse" value="#{row.cells[ind].ref.expandable ? !row.cells[ind].ref.expanded?'[ + ]':' [ - ]': ''}" rendered="#{ind==0}" onclick="expandCollapseColumn(#{rowKey},#{ind})"/>

</rich:columns>
</rich:scrollableDataTable>

Here is my demo class structure

public class Grid {

public class Column {
private String name;
private String value;
private boolean visible;

//getter setters for all the variables

}

}

When i add the visible attribute i get this exception. I can't seem to find out what is wrong. I can use the "rendered " attribute to show/hide columns but more appropriate would be the visible attribute.

 </rich:columns>

 </rich:scrollableDataTable>
 <a4j:commandButton action="#{dataTableScrollerBean.showAllColumns}" value="show all columns" reRender="table"/>
 </h:form>

and

 public void showAllColumns() {
 for (Facet column : columns) {
 column.setVisible(true);
 }
 }

this slightly changed code from RF demo (columns sample, dataTAble changed to scrollable and action to show added). works fine for me.
