[TYPO3-dev] Anybody here good in JS, Prototype and so on? (Date2Cal)

[Steffen Ritter]

UPDATE:
I found out, that _object is based on a new behaviour of prototype.
prototype Version in T3 4.1.5 $H() does something different than in 
updated Version in 4.2..
I will have a Look how to adapt date2cal to work with this new class Hash.
