Thanks for your input Marc. Let's stick with this one until something 
better comes up.

The Json library adds function like "toJsonString" to data types like 
Array. So if you have associative arrays you can't use the

for (var x in y)

anymore, because the function is part of the array. Well, there aren't 
many situations where this construction is used in Mapbender, but maybe 
this advice is helpful to someone someday.

Cheers,

Christoph
