具有类别/特色的自定义组件和router.php

Question

我正在使用Joomla 3.9 我已经开发了一个自定义组件。 在我的组件中，此路由器代码有效。 该代码适用于：

1. 表单搜索

/ myform / first_speciality_alias

/ myform / second_speciality_alias

1. 列表视图

/ myform / first_speciality_alias

/ myform / second_speciality_alias

1. 详细信息视图

/ myform / first_speciality_alias / third_reference

/ myform / second_speciality_alias / fourth_reference

1. 通过直接URL访问

此路由器代码在做什么？ 他将我的表单字段之一与URL同步。

问题是，我还需要特殊菜单项。 但是，一旦我创建了特色菜单项；

1. 情况1确实： / myform / first_speciality_alias / first_speciality_alias
2. 一旦我单击菜单中存在的first_speciality_alias，URLS就会变为 / myform / first_speciality_alias / first_speciality_alias / myform / first_speciality_alias / second_speciality_alias <=当我单击表单中的second_speciality_alias
3. 详细信息视图不起作用，它显示列表视图。
4. 从直接URL访问似乎可以工作1/2次。
