Does Javet support assignment operations on nested complex objects after performing a bind?

[eastack]

Javet looks fantastic! I tried assigning properties to a binded object that contains complex objects, and the result left me a bit confused. I went through almost all the documentation, but I’m still not sure what’s happening or how I should proceed. Could you help clarify this for me?

    public static void main(String[] args) throws JavetException {
        try (V8Runtime v8Runtime = V8Host.getV8Instance().createV8Runtime()) {
            JavetStandardConsoleInterceptor javetStandardConsoleInterceptor = new JavetStandardConsoleInterceptor(v8Runtime);
            javetStandardConsoleInterceptor.register(v8Runtime.getGlobalObject());

            User me = new User();
            try (V8ValueObject v8ValueObject = v8Runtime.createV8ValueObject()) {
                v8Runtime.getGlobalObject().set("me", v8ValueObject);
                v8ValueObject.bind(me);
            }

            Password password = new Password();
            try (V8ValueObject v8ValueObject = v8Runtime.createV8ValueObject()) {
                v8Runtime.getGlobalObject().set("password", v8ValueObject);
                v8ValueObject.bind(password);
            }
            password.setHashedPassword("${plain}12345");
            password.setHashMethod("plain");

            //me.setPassword(password);
            // Commenting out the line above will print -> "me.password is initially null."
            // Uncomment out the line above will set password value in java and print -> "me.password is initially undefined."

            v8Runtime.getExecutor("console.log(`me.password is initially ${me.password}.`);").executeVoid();
            v8Runtime.getExecutor("console.log(`password is initially ${JSON.stringify(password)}.`);").executeVoid();
            // set password in js will throw exception
            // Caused by: com.caoccao.javet.exceptions.JavetException:
            //      Callback signature mismatches:
            //          expected parameter type is class me.wangheng.javet.Password,
            //          actual parameter type is class java.util.HashMap
            v8Runtime.getExecutor("me.password = password;").executeVoid();
            v8Runtime.getExecutor("console.log(`me.password is initially ${me.password}.`);").executeVoid();
        }
    }

I just wrote that code based on intuition. Is it inappropriate to use bind the way I did in the code I provided? The behavior feels a bit odd. Do you mean to suggest that I should set the converter to JavetProxyConverter, set the necessary classes to JavetProxyConverter, and then construct the classes in JS and assign the values?

And I guess you might want to check JavetBuddy out. JavetBuddy can translate JavaScript objects into Java objects at byte code level.

Thanks a lot, I'll take a look when I have time. Work has suddenly gotten busy recently.
