TYPO3 Core

Our extensions use ext_conf_template.txt to define extension settings.

Some settings for the development systems are overriden in a local devevelopment AdditionalConfiguration.

When changing the extension configuration in the backend UI the fields get prefilled with the values from AdditionalConfiguration and are moved to LocalConfiguration when hiting "save".

This is a major issue if the live system should use the values from LocalConfiguration which then suddenly are overriden with local dev values.

The etension configuration should use the same mechanims as the regular configuration and show a message like this:

Note that $GLOBALS['TYPO3_CONF_VARS'] currently contains a different value. This could mean that the value is overwritten in AdditionalConfiguration.php.
