[TYPO3-mvc] Get related 1:n object from external class

[Henry DoShell]

Hi Gianluca,

a big thank you for your help. You spotted me to the right direction, I was able to solve the problem. 

Here's my corrected Roomrate model:

	/**
	 * Returns the sellingrate
	 *
	 * @return \float $sellingrate
	 */
	public function getSellingrate() {
		return $this->roomratenum*$this->conversionrate->getConversionratenum()*(1+($this->markup->getMarkupnum()/100));
	}

Had to add an markup, too.

Thanks again a lot
