I have two scenarios:
1) Render a chart to an image
2) Load a rptdesign file, read a chart and render it to an image.
I have described a problem with the rendered image in scenario 1) in a
previous post.
In scenario 2) I don't even get to render the image, the application fails
in this line:
gcs = gr.build(dServer, chart, bo, null, null, null);
with the error:

In scenario 2) the code that loads the rptdesign file is in one project and
the code that renders the chart is in another project. When I load the
rptdesign I set the BIRT_HOME to my local birt rte:
try {
designConfig.setProperty("BIRT_HOME","C:\\birt-runtime-2_6_1\\ReportEngine");
Platform.startup(designConfig);
IDesignEngineFactory designFactory = (IDesignEngineFactory)
Platform.createFactoryObject(IDesignEngineFactory.EXTENSION_DESIGN_ENGINE_FACTORY);
IDesignEngine designEngine =
designFactory.createDesignEngine(designConfig);
session = designEngine.newSessionHandle(ULocale.ENGLISH);
} catch (Exception e) {
logEngineError(e);
}
In the code for rendering the chart I have tried various approaches:
PlatformConfig pf = new PlatformConfig();
//pf.setBIRTHome("C:\\birt-runtime-2_6_1\\ReportEngine");
// pf.setProperty("STANDALONE", true);
// Returns a singleton instance of the Chart Engine
ChartEngine ce = ChartEngine.instance(pf);
IGenerator gr = ce.getGenerator();
But I get the same error. Any ideas why my application fails when I start
with loading a rptdesign file?
The jar: org.eclipse.birt.chart.engine.extension_2.6.1.v20100902.jar is both
on the build path (added as a maven dependency) of my project and in the:
C:\birt-runtime-2_6_1\ReportEngine\plugins folder.
Maybe its related to this post:

I have nailed down to where the error occurs. At runtime I update some
values on a Series object with a NumberDataSet:
Double[] arr = new Double[values.size()];
for (int i = 0; i < arr.length; i++) {
Float val = values.get(i);
if (val != null) {
arr[i] = new Double(val);
}
}
NumberDataSet seriesValues = NumberDataSetImpl.create(arr);
EList<Series> series = seriesDef.getSeries();
Series serie = series.get(0);
serie.setDataSet(seriesValues);
testChartRender(chart);
when I try to render the chart after the serie.setDataSet(seriesValues) call
I get the error. The dataSet:
DataSet dataSet = serie.getDataSet();
is null. But why does the call:
serie.setDataSet(seriesValues);
prevent the chart from being rendered and why such a wierd error message?
