It believe Cewolf only calls the produceDataset() method
if one of its parameters has changed values or if the
hasExpired() method returns true. This is a *great*
feature. However, it appears that when you add a
Tooltip and/or Link generator to a <cewolf:img> tag (as
shown below), the above image-caching mechanism no
longers works. As a result produceDataset() is called
whenever the browser page is refreshed.
<cewolf:img chartid="myChart" renderer="cewolf"
width="300" height="300">
<cewolf:map tooltipgeneratorid="myDataset"
linkgeneratorid="myDataset" />
</cewolf:img>
