Problem with Workbench Chart demo

[Bill Lear <ra...@zopyra.com>]

I just downloaded the latest Tapestry (2-4.alpha-4) and followed the
setup instructions for Jetty, downloaded the following jars:

jcommon-0.6.4.jar
jfreechart-0.9.6.jar
mckoidb-0.94h.jar
mckoidb-0.94h-jmx.jar

and put them in ext-dir.  I ran 'ant -emacs run-workbench' and things
started fine, clicked on localhost:8080/workbench, and then clicked on
the Chart tab.  Got the following error (sorry for the gory details),
included below.  The Chart page loaded ok, without a Chart.  I checked
the source code for jfreechart and the 0.96 code includes the
method that seems to be missing:

    /**
     * Returns a value.
     *
     * @param item  the value index.
     *
     * @return the value (possibly <code>null</code>).
     */
    public Number getValue(int item) {

        Number result = null;
        if (getItemCount() > item) {
            result = (Number) this.data.getValue(item);
        }
        return result;

    }

I have the 0.96 jar file in the ext-dir as instructed, and I looked at
this file and it includes DefaultPieDataset.class, so I'm not sure
what is going on.

Sorry if this has been mentioned already ...
