我有一个用例，我需要使用迭代器调解器发送一些调用，并使用聚合调解器来聚合响应。当聚合调解器完成后，其中一个响应是我期望的部分，其他响应被附加到正文的末尾。
我创建了以下代理来演示问题（添加了大量日志信息，以便逻辑易于遵循）：

正如您所看到的，最后两个poc：data-reference-local条目被附加到正文的末尾。我有什么想法吗？
我看到的另一个奇怪的事情是聚合mmediator的第二个日志条目（outSequence :: resultAggregate），按预期显示所有三个结果。但是，日志条目originalResultAggregate仅显示第一个。这与我遇到的奇怪行为有关吗？
编辑：我注意到的另一件事是我添加的计数器功能不起作用（参见属性gb_iterate_cnt＆amp; gb_aggregate_cnt）。我究竟做错了什么？
问候，nidkil
