dataTable rows per page--user-defined??

[er...@novartis.com]

Hi,

I have a dataTable with dataScroller. I'd like the user to be able to 
change how many rows are displayed per page. The following code displays 
the table and scroller just fine,
<t:dataTable binding="#{myBean.dataTable}" rows="15" ...>
...

But this code causes an exception:

<h:outputText value="Rows per page:"/>
<h:inputText binding="#{myBean.dataTable.rows}"/>

Exception:

Caused by: javax.faces.el.EvaluationException: Bean: 
org.apache.myfaces.component.html.ext.HtmlDataTable, property: rows
        at 
org.apache.myfaces.el.PropertyResolverImpl.setProperty(PropertyResolverImpl.java:410)
        at 
org.apache.myfaces.el.PropertyResolverImpl.setValue(PropertyResolverImpl.java:173)
        ... 55 more
Caused by: java.lang.IllegalArgumentException: argument type mismatch

        at 
org.apache.myfaces.el.PropertyResolverImpl.setProperty(PropertyResolverImpl.java:406)
        ... 56 more

Anyone know what I'm doing wrong?

Thanks,
Eric Jung
