[TYPO3-templavoila] Making <displayCond> work in Preview

[Jonathan Uhlmann]

Hi Guys

I've working on a FCE with multiple Areas for Content Elements. In that FCE the User can choose how many columns the Element should render. With <displayCond> I've got an easy way to disable the field in the element view itself, but it doesn't work in the Preview. It is possible the make the <displayCond> work in the Preview or set the <preview> Tag dynamically?

Thank you for any ideas!
Jonathan
