I have written the TYPO3 extension "cewrap", which adds new fields to table tt_content. Problem is, when installing an extension which introduces new content elements (e.g. EXT:gridelements) and this extension is loaded after my extension (because of its position in PackageStates.php), the fields from my extension are missing in the new content elements.
Is there a solution for that problem? Is there a way to affect the order of the entries in PackageStates.php?
Adding the packages you want to come before your own package, as entries in the suggest
properties of composer and TER manifests, should sort them as such in PackageStates.php
