[TYPO3-mvc] Fluid - accessing an object property by a dynamic index

[Alexander Dick]

Hi Bastian,

Cool, I already thought about a ViewHelper, but I did not know how to 
implement it.
Still, with this PropertyViewHelber I do not quite get how this would 
work in my case.

<f:for each="{data}" as="item">
	{someOtherObject.`item.uid`.title}
</f:for>

cheers
Alex
