Hi,
I'm trying to create a minimal JavaScript shell that has a global
load() function. I would like to add properties to the load() function
object. I have the following code
public class Shell extends ScriptableObject {
private Context cx;
public Shell() throws Exception {
cx = Context.enter();
cx.initStandardObjects(this);
String[] names = {"load"};
defineFunctionProperties(names,
Shell.class,
ScriptableObject.DONTENUM);
ScriptableObject loadObject =
(ScriptableObject)ScriptableObject.getProperty(this, "load");
loadObject.defineProperty("prop",
Shell.class,
0);
}
public String getProp() {
return "the prop value";
}
// definition of load function etc all of which seems to work...
}
When I run the following JavaScript in this shell
load.prop;
I see the following error message
java.lang.IllegalArgumentException: object is not an instance of declaring class
org.mozilla.javascript.WrappedException: Wrapped

Any ideas what I have done wrong?
