[TYPO3-dev] displayCond working with more sheets?

[Georg Ringer]

Hello,

I just tried displayCond
---------
    <sizeHead>
     <TCEforms>
      <displayCond>FIELD:display:=:PRO</displayCond>
      <label>LLL:EXT:rgpopup/locallang_tca.php:rgpopup.pi_flexform.sizeHead</label>
      <config>
       <type>input</type>
       <size>3</size>
      </config>
     </TCEforms>
       </sizeHead>
--------

and I just wonderd how I can use it for a whole sheet or for a field in 
another sheet... Is this possible?

thanks
georg
