How can you make a java object visible to a chart script?
addScriptableJavaObject doesn't seem to do the trick.

addScriptableObject is deprecated, but you can register it in the appContext
of IReportContext. To access it in a chart script, if you use
IChartScriptContext.getExternalContext().getScriptable(), it will return you
an instance of IReportContext
So something like this should work:
function beforeGeneration(chart, icsc) //any chart script function here
{
icsc.getExternalContext().getScriptable().getAppContext().ge t( "variableName");
}
Thanks,
David

Much Thanks!!
I'd still been using addscriptablejavaobject because it had been easier
not to change it from older versions.
I didn't recognize that the IReportContext returned by getScriptable was
the same one being used in the Report Engine code.
So many contexts....
Thanks,
Justin
