Bug #69750
Updated by Mathias Schreiber almost 9 years ago
TCA select fields with renderMode tree do not save the collapsed state any more.
The reason for this seems to be, that the @top.TYPO3.BackendUserSettings.ExtDirect@ functionality was removed / replaced?
Currently the expanded state seems to be stored with @top.TYPO3.Storage.Persistent@ which does not seem to have any impact.
