java.lang.NoSuchMethodError: org.vaadin.addon.JFreeChartWrapper.setWidth

I want to show a graph and I get the following error.
jFreeChartWrapper 3.3.0
jFreeChart 1.0.19
Vaadin 6.6.7


Hi Mariana,
I think that you should use jFreeChartWrapper 2.5.0 with Vaadin 6.x


Now show it. But I have an error that was already happening to me and I can not find a solution,
Once I open the console screen (which is the one that shows the graphics), then the rest of the system stops working. It generates errors and disables me some things. The error is this: org.vaadin.addon.JFreeChartWrapper.detach (
Thanks Marco
