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

[Jeppe Donslund]

Hi Peter

I think what I need is the opposite of what would wrote

if.isTrue.numRows {
    Does the area contain elements with PID from the actual page, show it.
} else {
    Get the elements from the Global elements folder
}

Or maybe your code does that?

Jeppe
