Hi,
I am using eclipse 3.1.1 and BIRT 2.0.0 version.
I get org.eclipse.birt.chart.exception.ChartException: $NO-RB$ Source
value can not be null exception while loading the Chart.rptdesign file
and rendering it on canvas.
Here is the rptdesign file which I am trying to load and render.

I am able to open this file in Eclipses Report Design perspective and
able to preview it without any error.
But while rendering the same on canvas, it gives exceptions.
The code was working fine with BIRT2.0M3 version, and chart was rendering
properly without any error.
But its not working with BIRT 2.0RC versions and BIRT2.0.0 version.
Code that I am using for rendering the chart:
public void paintControl(PaintEvent e) {
Chart chart = null;
try {
// Load chart from file and get it
chart = GraphDesignerUtility.getChart();
if (chart == null) {
// No chart available to render
}
else {
// Create copy of chart which will be used for rendering
Chart chartToRender = (Chart) EcoreUtil.copy( chart );
// Get a SWT device renderer
IDeviceRenderer deviceRenderer = null;
deviceRenderer = PluginSettings.instance().getDevice("dv.SWT");
deviceRenderer.setProperty(IDeviceRenderer.GRAPHICS_CONTEXT, e.gc);
//Make sure we stay in the client area's bounds
Rectangle rect = ((Composite) e.widget).getClientArea();
final Bounds bounds = BoundsImpl.create(rect.x + 2, rect.y + 2,
rect.width - 4, rect.height - 4);
bounds.scale(72d / deviceRenderer.getDisplayServer()
.getDpiResolution());
final Generator gr = Generator.instance( );
RunTimeContext rtc = new RunTimeContext();
// prepare the chart model.
//RunTimeContext rtc = Generator.instance( ).prepare( chartToRender,
// null,
// new BIRTScriptClassLoader( ),
// Locale.getDefault( ) );
//ScriptHandler sh = new ScriptHandler( );
rtc.setScriptHandler( sh );
//rtc.setEnableScripting( false );
GeneratedChartState state = gr.build( deviceRenderer.getDisplayServer(
),
chartToRender,
bounds,
null,
rtc,
null );
gr.render( deviceRenderer, state );
}
preservedValidChart = chart;
} catch (Exception ex) {
ex.printStackTrace();
graphView.refresh();
}
}
I also tried calling Generators prepare method, but found the same
problem.

Here is the flow that I am following to render the chart.
- Initialize BIRT by calling initializeBIRT() method. This loads the
empty.rptdesign file.
Here is the Empty.rptdesign
----------------------------

- Then load the saved chart.rptdesign using openRptDesignFile() method.

Thanks, I also need the DatasetUtility class and the PaintListener class.
Maybe can you try this: remove the line: Chart chartToRender = (Chart)
EcoreUtil.copy( chart );
I am not sure it will copy the Dataset, this might be the problem, but it's
nothing new to 2.0 though. Otherwise, I imagine you call runreport before
getting the chart?
Thanks,

I tried commenting Chart chartToRender = (Chart) EcoreUtil.copy( chart );
but not working.
I am also calling runReport before rendering the chart. Still its not
working.

Hi,
I think I found the problem. This is due to the new engine architecture, but
it might well be a bug in fact. What happens is that the report is now
created in two steps: generation and presentation (that can occur at
different machines at different times). The data generated at generation
time is deserialized during presentation for further processing. In the case
of chart, the chart instance is deserialized, resulting in a new instance of
the chart, which is the one that is bound to the data. The original one in
the report design handle is not modifed, that's why it is still empty. You
can file a bugzilla entry for this issue.
In the meantime, I think one solution is to use scripting in java: that
would allow you to get a hook on the runtime chart instance while the report
is rendered. For this you have to implement
ChartEventHandlerAdapter.afterDataSetFilled and modify you report design to
register your event handler class in the chart (property editor view/event
handler). Then when you run the report, it will instantiate your event
handler and call the method afterDataSetFilled. In there you can get the
chart instance from the IChartScriptContext and pass it to one of your class
(maybe make one of them a singleton for that purpose). Then you can retrieve
the chart from there later on. I know this is not ideal, but I didn't see a
better solution so far.
Thanks,
David

Hi,
The Chart dialog can take a chart design instance (not filled with data) as
input. It will internally bind it to data and display it. So that's why it's
working. In your application you're getting a chart design instance as well,
but the chart engine will not try to bind it with data, if you don't ask for
it. In your scenario you expect the report to bind data when it runs, and
that's the bug we discussed about, the bound instance cannot be retrieved
afterwards.
The chart dialog can do this databinding by itself without running the
report. You might wonder if you can do the same thing, it's certainly
possible but there are some limitations:
1- If you bind data outside the report, you can't have data that is
dependent on report runtime expressions such as report parameters(params),
report configuration(config), etc...
2- You cannot use the external context in your chart script if you have any,
since there won't be any report context available.
If you're still interested in this way of doing things that avoids running
the report to bind and render the chart, I can provide more guidance, let me
know.
Thanks,
David

Is it possible that you send me your plugin with its dependencies in a zip
so that I can debug it and see how to fix it. I could make a few more
guesses, but it's likely to take time to resolve this. If I could debug,
that would really speed up the resolution.
Thanks,

Ok, I think the best option now is to file a bug for this issue, I will
spend some time to reproduce this problem. One thing you could try is set
the classpath to your script through one of those system variables:
public static final String WEBAPP_CLASSPATH_KEY =
"webapplication.projectclasspath"; //$NON-NLS-1$
public static final String WORKSPACE_CLASSPATH_KEY =
"workspace.projectclasspath"; //$NON-NLS-1$
public static final String PROJECT_CLASSPATH_KEY = "user.projectclasspath";
//$NON-NLS-1$
I'm not sure it will work as they might be overriden at some point, but that
is where the script classloader is currently looking at.
Alternatively you can try to use the Chart API to execute the chart directly
rather than going through the report generation. This requires some work,
but it will also let you plug your own class loader through
IScriptClassLoader. It should also be somewhat faster to simply run the
chart, than the full report. I don't know how your data is available to you,
but you can feed it to the chart through a sql.ResultSet for instance. You
can create the chart using the chart model api, or extract the xml from the
report design, save it in a file and load it directly with the Chart API.
Thanks,
David

Hi,
I set the webapplication.projectclasspath to my project class path.
Now My GraphEventHandler class is coming in picture.
But the method afterDataSetFilled is not being called by BIRT.
I have implemented following two method and those are being called.
public void beforeRendering( GeneratedChartState gcs,
IChartScriptContext icsc )
{
System.out.println("IN GraphEventHandler beforeRendering");
}
public void afterRendering( GeneratedChartState gcs,
IChartScriptContext icsc )
{
System.out.println("IN GraphEventHandler afterRendering");
Chart chart = icsc.getChartInstance();
GraphDesignerUtility.chart1 = chart;
System.out.println(" after IN GraphEventHandler afterRendering");
}
It displays println statements at console.
I tried to assign the chart instance to one memeber variable of my class
in afterRendering() method.
But the member variable doesn't get initialized.
Control goes in wait mode.
Event it doesn't execute the next statement(System.out.println(" after IN
GraphEventHandler afterRendering");).
Kindly inform me what I'm doing wrong here.
Thanks.
