Hi,
I tried to use Delegator class to implement some functionality on variable
assignment. I have my object that implements Scriptable and would like to
call additional functionality when instances of this objects are assigned to
variable. Here is a part of my JUnit test for this class.
final Context context = ContextFactory.getGlobal().enterContext();
final ScriptableObject scope = context.initStandardObjects();
final Delegator delegator = new Delegator(scope);
ScriptableObject.putConstProperty(delegator, "imports", new
ImportsObject(
scope, null));
context.evaluateString(delegator,
"const test = imports.net.antshell.missing;", "no name", 0,
null);
When I run this test I get following exception:
java.lang.Exception: Unexpected exception,
expected<org.mozilla.javascript.WrappedException> but
was<java.lang.StackOverflowError>

I wanted to override put method in Delegator and implement my functionality
in this place. Is there any other way to do it? I must be honset this my
first week with Rhino.

Jarek
