[news.eclipse.birt] How to access the underlying chart object in a repor

[Stuart Roe <stuart.roe@xxxxxxxxxx>]

Can anyone help me with accessing the underlying chart object within the 
design returned from <engine>.openReportDesign(..).

I have managed to locate the ExtendedItem object for the chart within the 
design and I'm able to see the reference Chart object (cm) within the debugger 
but I'm unable to locate a method to return the reference.

The boiled down version of my code currently consists of:

design = beng.getEngine().openReportDesign("test.rptdesign");
DesignElementHandle dh = design.getDesignHandle();
DesignElement chartDE = dh.getModule().findElement("Chart");
ExtendedItem chartEI = (ExtendedItem)chartDE;
IReportItem elementRI = chartEI.getExtendedElement();

I can see the cm member with elementRI (typed ChartReportItemImpl), but I'm 
unable to access it.

Why am I doing this?
I'm creating a library which will allow our development staff to use BIRT to 
define various charts and reports (including the appropriate SQL). These will 
be loaded into our application when the user selects various options.

With the charts, these will be presented to the user as part of the page. If I 
can get the chart object I think that I'll be able to render the chart 
straight into a swing component.

The reports will be rendered to HTML and displayed via an integrated browser 
window.

Thanks for any help,

Stuart.
