[TYPO3-ect] lib/div: Overriding TS config via FF

[Jochen Rieger]

Hey lib/div devs,

finally I managed to dig deeper into the lib/div framework instead of 
just following the mailinglists discussions about it. A long awaited 
situation! :)

I found one behaviour to be worth changed (or maybe I just did not find 
the right way to do it):

When retrieving configurations via

$this->configurations->get('someConfKey');

I will ALWAYS get the FF value in case the same key exists in TS and FF. 
I think it might be better to use the flexform value ONLY IF something 
was entered there. Would be kind of a nobrainer in

class.tx_lib_configurations.php:

foreach((array) $data as $sheet => $languages) {
	foreach((array) $languages[$languagePointer] as $key => $def) {
		
		// just use ff value if something was entered
		if ($def[$valuePointer] != '') {
			$this->set($key, $def[$valuePointer]);
		}
	}
}

What do you think?

Cheers,
Jochen
