According to the exception, you’re passing a value of 0 to offsetGet(), but there isn’t an offset of 0 in $this->Data. The code seems to be doing exactly what it’s supposed to be doing, as far as anybody here can tell (without knowing any runtime values).

public function offsetGet($Offset) // <--- receives a value of 0
{
    if (isset($this->Data[$Offset])) { // <--- evaluates to "false"
        return $this->Data[$Offset];
    }
    else {
        throw new RInvalidCollectionOffsetException($Offset); // <--- throws exception
    }
}
