LinkItemCollection showing [Object, object]

[whoisyourvladie]

MenuItemBlock showing [Object object] instead of link names

There are traces that there was an attempt to fix it:

• a dojo file ~\src\Foundation\modules_protected\Foundation\Scripts\MenuChildItems.js that tries to fix it.
• Attribute [ClientEditor(ClientEditingClass = "foundation/MenuChildItems")] over the ChildItems property in ~\src\Foundation\Features\Blocks\MenuItemBlock\MenuItemBlock.cs (commented out)

If you uncomment the attribute - the block won't open for editing and you get an error in browser console:

Uncaught Error: declare: mixin #0 is not a callable constructor. at err (dojo.js:3999:32) at c3mro (dojo.js:4012:5) at declare (dojo.js:4732:12) at MenuChildItems.js:15:16 at runFactory (dojo.js:1107:43) at execModule (dojo.js:1236:5) at dojo.js:1271:6 at guardCheckComplete (dojo.js:1251:5) at checkComplete (dojo.js:1266:4) at onLoadCallback (dojo.js:1428:7)
