TYPO3 Core

The CategoryRegistry is filled during the initial build of the TCA.

When the TCA is read from the cache the CategoryRegistry will not be filled.

This is a problem because the itemsProcFunc of tt_content.category_field relies on the values stored in the category registry.

Steps to reproduce:

• Create a content element with the CType "menu" and select one of the category menu types
• The select field "Category field" does probably not contain any items.
• Now clear the system cache
• And reload the Frame displaying the Form
• Now the value "Categories" should be selectable for "Category field" (the expected behavior)
• Save the content element
• Now the select field says "INVALID VALUE ("categories")
