[TYPO3-dev] Change TCA definition of field based on tt_content CType?

[Franz Koch]

Hi,

do you guys know a way to manipulate the TCA of a certain field based on 
the selected CType in tt_content?

Example:
I created a new CType that should render a 360° panorama scroller which 
uses a image defined in "tt_content.image". Everything is fine that far, 
but I like to change that field for this CType to maxItems=1 and size=1.

Any chance to do that? I know that I can add/remove select options based 
on CType via pageTS - but changing something like maxItems or size seems 
not to be possible. But maybe I'm simply to tired to see the overall 
solution. I'm using Typo3 4.2.6 btw. but would switch to 4.3dev if it's 
possible there.

Thanks.
