在嵌套视图中按回会引发错误“指定的子级已经有父级”。

Question

我使用BottomNavigation 设置了嵌套视图，用户可以通过该视图从ListView 导航到详细信息“页面”之一。我已经尝试过手动路由以及 Vue Navigator

这是我的应用程序的布局。

<!--Main.vue-->
  <Page>
    <BottomNavigation>
      <TabStrip class="bottom-navigation">
        ...
      </TabStrip>

      <TabContentItem>
        <Frame>
          <Dashboard />
        </Frame>
      </TabContentItem>

      <TabContentItem>
        <Frame>
          <Finance />
        </Frame>
      </TabContentItem>

      <TabContentItem>
        <Frame>
          <Profile />
        </Frame>
      </TabContentItem>
    </BottomNavigation>
  </Page>

<!--Finance.vue-->
  <Page>
    <Tabs>
      <TabStrip class="tab-strip">
        ...
      </TabStrip>

      <TabContentItem>
        <ListView
          for="item in items"
          @itemTap="$navigateTo(detailPage)"
          class="list-group"
          height="100%"
        >
          ...
        </ListView>
      </TabContentItem>

      <TabContentItem>
        ...
      </TabContentItem>
    </Tabs>
  </Page>


<!--ItemDetails.vue-->
  <Page>
    <ActionBar class="action-bar">
        <NavigationButton @tap="$navigateBack" android.systemIcon="ic_menu_back"/>
        <Label class="action-bar-title" :text="item.name"></Label>
    </ActionBar>

    <GridLayout>
        ...
    </GridLayout>
  </Page>

这是按详细信息页面的后退按钮时出现的错误。

应用程序崩溃，我无法找出可能导致错误的原因。请帮忙。
