Yes, it's me who put out the bug-fixed version.
The cewolfexample web app that comes with it has a number of examples that show how to pass parameters around.
In your example of one chart per employee, you'll probably have a loop in the JSP that iterates over all employees. In the loop, you'd have a <cewolf:chart> tag and a <cewolf:img> tag. Inside the chart->data->producer tag you can use EL to create different IDs that retrieve the chart objects with corresponding names. Earlier, in your
servlet, you'd have put these objects into the request scope as attributes.
If the DatasetProducer class needs parameters, then you can pass them in the constructor, or through regular setter methods. This all happens in the servlet code, so you can do everything that normal Java code can do, including accessing a database to retrieve the data required for the charts.
