Hi,

I get following error message, when I try to use the attribute 'ajaxKeys' of a scrollableDataTable:

javax.faces.convert.ConverterException: Value 3 is not supported by this converter

On the page I'm using following code:

<rich:scrollableDataTable id="test" height="200px" rowKeyVar="rowKey" rows="0" var="item" value="#{test.values}" ajaxKeys="#{test.ajaxKeys}">
 <rich:column id="col1">
 <f:facet name="header">col1</f:facet>
 <h:outputText id="out1" value="#{item[0]}"/>
 </rich:column>
 <rich:column id="col2">
 <f:facet name="header">col2</f:facet>
 <h:inputText id="in1" value="#{item[1]}">
 <a4j:support event="onchange" reRender="out2"/>
 </h:inputText>
 </rich:column>
 <rich:column id="col3">
 <f:facet name="header">col3</f:facet>
 <h:outputText id="out2" value="#{item[2]}"/>
 </rich:column>
</rich:scrollableDataTable>

and in the associated bean (which is in the session scope):

public class MyTest {

 private ArrayList<ArrayList<String>> values;
 private Set<Integer> ajaxKeys;

 public MyTest ()
 {
 ajaxKeys = new HashSet<Integer>();
 ajaxKeys.add(3);
 }

 public Set<Integer> getAjaxKeys()
 {
 return ajaxKeys;
 }

 public ArrayList<ArrayList<String>> getValues()
 {
 if (values == null)
 {
 values = new ArrayList<ArrayList<String>>();
 for (int row = 0; row < 10; row++)
 {
 ArrayList<String> columns = new ArrayList<String>();
 values.add(columns);
 for (int col = 10; col < 20; col++)
 {
 columns.add("cell"+row+"/"+col);
 }
 }
 }
 return values;
 }
 ...

If I use the code with a rich:dataTable or a rich:extendedDataTable it shows the expected behaviour (the 3. column in the 4. row is rerenderd) but with rich:scrollableDataTable the error occurs.

Any ideas what I'm doing wrong?

Thx in advance
Joerg
