Gwt RequestFactory：收到后立即编辑代理

Question

我想在Receiver.onSuccess中收到RequestContext.edit（anObject）之后立即将它放在我的客户端数据库中，因为我已经可编辑了。不幸的是，当我这样做时，RequestFactory抱怨请求已在进行中。我怎样才能做到这一点？

requestContext.findOrganization(id).fire(new Receiver<OrganizationProxy>()
{
    public void onSuccess(OrganizationProxy response)
    {
        database.put(requestContext.edit(response)); //fails because a request is already in progress
    }
});

我通过使用一次性请求上下文来创建请求，然后使用我更永久的请求上下文来编辑对象来解决这个问题：

temporaryRequestContext.findOrganization(id).fire(new Receiver<OrganizationProxy>()
{
    public void onSuccess(OrganizationProxy response)
    {
        database.put(permanentRequestContext.edit(response)); //succeeds because it has not been fired, even though edit() has been called many times
    }
});
