[TYPO3-ect] div Fatal error: Cannot use string offset as an array

[Franz Holzinger]

Hello,

when the tx_div_ff::getFFValue has been called and it gives the result
$_flexForm Line 1: no element found

then this function causes a PHP fatal error.

Proposal:

if (is_array($_flexForm))	{
	$sheetArray = $_flexForm['data'][$sheet][$lang];
	$result = null;
	if (is_array($sheetArray)){
		$result =
self::getFFValueFromSheetArray($sheetArray,explode('/',$fieldName),$value);
	}
} else {
	$result = $_flexForm;
}
return $result;

Or maybe a better error message should be returned in an error parameter.
