Hi,
When I want to create a Chart (irrespective of the chart type) with the
data coming from a Scripted Data Source, BIRT gives me the following
errors.
Any help in this regard is highly appriciated.
Thanks in Advance,
Ravi

| Urgent:Re: Charting with Scripted Data Source [message #145802 is a reply to message #144908] |

Could some provide some insight into the posted problem, earlier.
What I had notices is that, When I create a scripted data source, as
described in one of the examples/tutorials which doesn't access any user
based classes but accesses only JDK java.* classes, and assign values to
the data source columns, I could see the preview results, and hence the
chart associated to these columns.
But when I use the scripted data source programmed to access my
application classes, it doesn't show any preview results, and hence fails
by showing the error message as posted earlier.
Am I missing anything?
Thanks in Advance,
Ravi.
