Showing previously in menu hidden pages needs cache flush

[jonakieling]

Hello there,

setting nav_hide to 1 invalidates cache and the page is no longer shown in the menu.

ISSUE: setting nav_hide back to 0, the page is still hidden.

Versions

TYPO3 12.4.28
b13/menu 1.1.2

This is my test setup with a clean TYPO3 installation.

# Default PAGE object:
page = PAGE
page.10 = COA_INT
page.10 {
  10 = TREEMENU
  10.entryPoints = 1
  10.depth = 2
  10.includeNotInMenu = 0
  10.renderObj.level0 = TEXT
  10.renderObj.level0.typolink.parameter.data = field:uid
  10.renderObj.level0.typolink.ATagParams = class="active"
  10.renderObj.level0.typolink.ATagParams.if.isTrue.field = isInRootLine
  10.renderObj.level0.dataWrap = <li class="firstLevel">|<ul>{field:subpageContent}</ul></li>
  
  10.renderObj.level1 = TEXT
  10.renderObj.level1.typolink.parameter.data = field:uid
  10.renderObj.level1.typolink.ATagParams = class="active"
  10.renderObj.level1.typolink.ATagParams.if.isTrue.field = isInRootLine
  10.renderObj.level1.dataWrap = <li class="firstLevel">|<ul>{field:subpageContent}</ul></li>
  
  10.renderObj.level2 = TEXT
  10.renderObj.level2.typolink.parameter.data = field:uid
  10.renderObj.level2.typolink.ATagParams = class="active"
  10.renderObj.level2.typolink.ATagParams.if.isTrue.field = isInRootLine
  10.renderObj.level2.dataWrap = <li class="firstLevel">|<ul>{field:subpageContent}</ul></li>
  
  20 = TEXT
  20.value = Hello World!
}

This is the in-project setup that does not work (sidenote: only top-level pages stay hidden, subpages are correctly displayed, haven't figured out why yet)

page = PAGE
page {
  10 = FLUIDTEMPLATE
  10 {
    dataProcessing {
      10 = B13\Menus\DataProcessing\TreeMenu
      10.entryPoints = 1
      10.as = mainNavigation
      10.depth = 2
    }
  }
}

Findings and Debug

When I talk about a page being shown or not shown I always set nav_hide on this page. This report does not talk about subpages being hidden, when parent pages are changed.

When includeRootPages is set to 1 in the above example, pages Subpage [1] and Subpage2 [4] are correctly shown again, when setting nav_hide to 0. Nested Subpage [3] and Nested Subpage2 [5] still stay hidden, when setting nav_hide back to one.

When includeRootPages is set to 0 all pages have the cache invalidation issue (except in our project, see sidenote above)
