Thanks for all the hints!
The screencasts are great and the Examples are also very valuable. BUT they
only showed me that I am doing it right ;-)
The problem seems to be that the Wonder-Ajax-Components use „prototype“ on the
client side. There a $-Function is defined.
But in my Project this Function is overwritten by jQuery. And now the
java-script-function getValue (prototype) accidentally uses the $-Function of
jQuery.
I am no java-script-expert. But if someone knows how to prevent jQuery from
overwriting the $-Function of prototype, I would really be grateful!
And please don’t tell me: „Do not use both on the same site“ ;-). It’s a quite
large project and I do not think this would be an option.

Kenan
