[TYPO3-english] Check if an area doesn't contain elements

[Jeppe Donslund]

Hi

This:

lib.element1 = COA
lib.element1 {
    10 = RECORDS
    10.dontcheckPid = 1
    10.tables = tt_content
    10.source = 47
}


lib.btm_elm_1 = COA
lib.btm_elm_1 {
     10 = RECORDS
     10 {
         source.current = 1
         tables = tt_content
         stdWrap {
             ifEmpty.cObject < lib.element1
         }
     }
     stdWrap {
         required = 1
         wrap = <!--TYPO3SEARCH_begin--> | <!--TYPO3SEARCH_end-->
     }
}

This does show if there are content, but if there are no content the 
area is empty. It does not show element uid 47.
