RF 'Unfrozen bean with null RequestContext' when using a ValueProxy param with JsonRpc dialect

Question

When i try to send a request that uses a ValueProxy params i'm getting this 'Unforzen bean' exception. I don't know if this exception is because a bug with RF using JsonDialect or i'm doing something wrong... ¿Some help?

public void onModuleLoad() {

    someProxy.setSomeProperty("someValue");

    SomeRequestFactory.INSTANCE.context().SomeCall(someProxy).fire();

Proxies should be created by a RequestContext, not an AutoBeanFactory! Using the JsonRpc dialect doesn't change how you use RequestFactory.

public void onModuleLoad() {
   SomeRequestContext ctx = SomeRequestFactory.INSTANCE.context();
   SomeProxy someProxy = ctx.create(SomeProxy.class);
   someProxy.setSomeProperty("someValue");
   ctx.SomeCall(someProxy).fire();
}
