Bug #73165
Updated by Mathias Schreiber about 8 years ago
While trying to add a filter, that allows only default language items to be selected in a TCEform group field, I discovered that the filter methods do not get called for items, that the element browser renders as the translations of default language items.
To reproduce this error, you have to switch on the "Localization view" in the list module.
Due to this bug, it seems impossible to implement a group field filter, that allows only default language items to be selected.
