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

I want to do something similar to when you fill in columns for a scripted
data set, except use the java object to fill in legend information.

Could you tell me how to do that? If I called addScriptableJavaObject(
myObject ) does that mean that it is already in the context?
If not, how do I put it there?
If so, how do I access it?

Could someone please help me out here?
Specifically,
1. How can I make a Java object accessible from a chart script (I think
more specifically from the IChartScriptContext object that is already
visible) and,
2. How can I access the Java object from the context object.
In a scripted data set, the method you use would be
addScriptableJavaObject, is there a similar method to make such an object
part of the script context?
Please Help!
Justin

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
context.getScriptable().get

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
