TYPO3.TYPO3CR

/**

 * @scope prototype
 */
class Release {

    /**
     * @var string
     */
    protected $versionNumber;
}

$versionNumber is declared as string. If by some mistake $versionNumber contains an array of strings, the CR will persist the array (string[]) without problems (ignoring the class schema) but while reconstituting the object the CR complains with this exception:

#1181084521: getValue() cannot be called on multi-valued properties. (More information)
