为什么SDL Tridion 2011自定义解析器在发布组件时调用两次？

我有一个自定义解析器，它应用于Publication、StructureGroup、Page和Component类型的项。代码按预期运行，但我不清楚调用代码的确切时间。 我的Tridion.ContentManager.config文件包含以下摘录：

当我发布发布、StructureGroup或页面时，会调用一次自定义解析程序（这是我所期望的），但是当我发布组件（其架构链接到一个生成动态组件表示的组件模板）时，会调用两次自定义解析程序

---

这是预期的行为吗？如果没有，有人能建议为什么第二次调用我的解析器吗？

为组件调用一次解析器，为与组件架构关联的每个组件模板调用一次解析器。为该模式添加一个额外的CT将调用数量增加到三个

---

目前还不清楚这是一个bug还是出于设计，但解释了调用的数量。有趣的是，在取消发布组件时，只调用一次自定义解析程序。我注意到，对于当前发布操作的“范围”内的每个发布目标，都会调用自定义解析程序

有趣的一点是，组件并不恰好在页面上，是吗？不，不在页面上。我尝试从所有项目类型中删除解析器，但组件思维方式除外，但仍然如此。我想知道它是否为组件调用一次，为与组件模式关联的每个CT调用一次。我现在要做一个新的CT，看看它是否会被调用3次。是的，这也是我想到的，让我知道你的测试结果。当你回答你自己的问题时，这很好：）我会说它为组件本身调用一次（因此可能会解析为包含该组件的页面），为CTs调用一次。但是我以前没有检查过这些信息，如果是故意的，我也没有检查过。。。
