向Mule流添加新组件时发生命名空间问题

Question

我是Mule的新手，每当我使用固定频率调度程序添加'Poll'来处理mule流，获取命名空间错误。每当我们添加新组件以通过编辑器时，都不应该继续添加命名空间？我是否明确添加了与'poll'相关的命名空间？我期待民意调查的命名空间可以在Mule核心中使用。我正在使用Mule studio-3.5.0。

  

从元素开始发现无效内容   “固定频率调度”

这是骡子配置 -

编辑： 正如大卫所建议的那样，我试图通过跟随Mule documentations添加Mule 3.5.0 Runtime，但我找不到3.5.0 Cascade或BigHorn。

Answer 1

fixed-frequency-scheduler在Mule核心，但是Mule 3.5.0 Cascade或BigHorn，而不是当前正在使用的3.4.1 EE。

切换到这两个运行时之一，它将起作用。
