[TYPO3-mvc] Custom view helpers in a partial called multiple times

Thanks for the hint, but the cached template is rather hard to read :-( 
I have copied the problematic part to the Gist 
(https://gist.github.com/fsuter/4997023). Looking at it I can't really 
understand what's wrong.

As expected the same kind of code repeats itself twice and looks really 
similar, except for increasing numbers in the variables names. The weird 
thing is that the arguments passed to the partial the second time (the 
ones listed in $array32) are available in the partial, i.e. I can print 
them with a simple

<p>{formation}</p>

for example, and they get used correctly in my conditions, but they are 
rendered as empty inside my custom viewhelper:

<vd:wiki parseText="true">{formation}</vd:wiki>

I'm ready to believe that my view helper contains errors, but I don't 
understand why it works the first time and not the second time. BTW I 
have added the view helper's code to the Gist too.

Cheers
