TYPO3 Core

I am successfully using the spell checker plugin for a multitree site offering german and english subtrees.

I want to display all available dictionaries to the user independently from the language of the content element. So the user should use be able to select the english dictionary for a german content and vice versa.

How could I achieve this kind of setup. So far I am only able to define either the english or the german dictionaries as default, but not both at the same time.

safe_mode ist off. If I set forceCommandMode = 1 and
defaultDictionary = en I get a list of the following dictionaries: en,
en_CA, en_GB, en_US.

If I set defaultDictionary = de I get de, de_AT, de_CH, de_DE.

With defaultDictionary set to de_DE there is only de_DE in the list of
dictionaries.
