Hi,
I want to implement a Drill Through Functionality by using Java.
If the user clicks a bar in the chart, the SWT Browser should switch to a subreport with details to the selected Customer.
I tried two ways:
1) Trying to add a Trigger to the Series when opening the Report Design.
IReportRunnable design = reportEngine.openReportDesign(ReportTester.class.getResource AsStream(fileName));
Trigger trigger = TriggerImpl.create(TriggerCondition.ONCLICK_LITERAL,
ActionImpl.create(ActionType.SHOW_TOOLTIP_LITERAL,
TooltipValueImpl.create(100, "test")));
ExtendedItemHandle eih = (ExtendedItemHandle) design.getDesignHandle().getModuleHandle().findElement("barChart ");
ChartWithAxes chart = (ChartWithAxes) eih.getReportItem().getProperty("chart.instance");
Axis xAxisPrimary = chart.getPrimaryBaseAxes()[0];
Axis yAxis = chart.getPrimaryOrthogonalAxis(xAxisPrimary);
yAxis.getTriggers().add(trigger);
SeriesDefinition xSD = (SeriesDefinition) xAxisPrimary.getSeriesDefinitions().get(0);
Series xS = (Series) xSD.getSeries().get(0);
xS.getTriggers().add(trigger);
OR 2) Add a ChartHandler, that adds a Trigger to the Series
public class ChartEventHandler extends ChartEventHandlerAdapter {
public void afterDrawSeries(Series series, ISeriesRenderer isr,
IChartScriptContext icsc) {
series.getTriggers().add(TriggerImpl.create(TriggerCondition .ONCLICK_LITERAL,
ActionImpl.create(ActionType.SHOW_TOOLTIP_LITERAL,
TooltipValueImpl.create(100,
"test"))));
}
}
Both ways have no effects ...  Any Ideas? What am I doing wrong?

Tobias,
Any reason you are not just using the chart editor to do this?
On your scenario 1 does it show a tooltip? This should work. You can
create a url selection like:
MultiURLValues muv = MultiURLValuesImpl.create( );
URLValue uv = URLValueImpl.create( "http://www.actuate.com", //$NON-NLS-1$
null, null, null, null );
Label l = LabelImpl.create( );
l.setCaption( TextImpl.create( "www.actuate.com" ) );//$NON-NLS-1$
uv.setLabel( l );
muv.getURLValues( ).add( uv );
uv = URLValueImpl.create( "http://www.birt-exchange.com", //$NON-NLS-1$
null, null, null, null );
l = LabelImpl.create( );
l.setCaption( TextImpl.create( "www.birt-exchange.com" ) );//$NON-NLS-1$
uv.setLabel( l );
muv.getURLValues( ).add( uv );
uv = URLValueImpl.create( "http://www.eclipse.org", //$NON-NLS-1$
null, null, null, null );
l = LabelImpl.create( );
l.setCaption( TextImpl.create( "www.eclipse.org" ) );//$NON-NLS-1$
uv.setLabel( l );
muv.getURLValues( ).add( uv );
Trigger triger = TriggerImpl.create( TriggerCondition.ONMOUSEDOWN_LITERAL,
ActionImpl.create( ActionType.URL_REDIRECT_LITERAL,
muv ) );
sePie.getTriggers( ).add( triger );

Tobias,
If you want the trigger to hyperlink to a report you need to create an
ActionHandle from the DE API and then use the ModuleUtil class to
serizalize this into the baseURL of the trigger. Like:
try {
ActionHandle actionHandle =
ModuleUtil.deserializeAction((InputStream)null);
actionHandle.setLinkType(DesignChoiceConstants.ACTION_LINK_T YPE_DRILL_THROUGH);
actionHandle.setReportName("xyz.rptdesign");
actionHandle.setTargetFileType("report-design");
actionHandle.setTargetWindow("_blank");
actionHandle.getMember("paramBindings");
ParamBinding pb = StructureFactory.createParamBinding();
pb.setParamName("order");
pb.setExpression("row[\"yaxis\"]");
actionHandle.addParamBinding(pb);
String sBaseUrl = ModuleUtil.serializeAction(actionHandle);
Trigger tr = TriggerImpl.create(TriggerCondition.ONCLICK_LITERAL,
ActionImpl.create(ActionType.URL_REDIRECT_LITERAL, URLValueImpl
.create(sBaseUrl, null, null,null,null)));
bs1.getTriggers().add(tr);
} catch (SemanticException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (DesignFileException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
