[TYPO3-dev] TCA, wsitch the look of a field but using the same field name

[Ries van Twisk]

Hey devs,

example:
I have the following radio buttons in a BE form:
COLOR
HTML

What I want is that a field (called content) then switched from the RTE 
to a color selector.
I can manage to have them work apart.

How can I detect what radio is selected and to replace the config in 
content based on the above radio?
