Hi,
I want to display a line-chart for my application. I tested chenille-kit
chart component it worked quite good, but it does not support Dates on the
x-axis. I want to to draw time-series on the chart. So I decided to use
JFreeChart. The link
http://wiki.apache.org/tapestry/Tapestry5HowToCreateGenericGraphComponent
describes the usage of JFreeChart with Tapestry. I used to code as it is, I put
the Chart.java under components package, Prepared the LineChartPage.java and
LineChartPage.tml. The page rendered, displayed but the chart is not displayed.
When I look at the Jboss console I saw the "neither a stream response nor a
redirect response was generated for this action request." exception;
[org.apache.tapestry5.services.TapestryModule.RequestExceptionHandler]
Processing of request failed with uncaught exception: Sanity check - neither a
stream response nor a redirect response was generated for this action request.
java.lang.IllegalStateException: Sanity check - neither a stream response nor a
redirect response was generated for this action request.

Did anyone encountered this exception? Or do you have any idea of the cause? Or
a better solution to display time-series charts, which contain time information
on x-axis.
Regars,
