Okay, so I use your suggestion with the private native method.
We only use the JSNI in some cases where we have to use it. In a bridge to
a JavaScript lib for example.
Switching to GWT 2.8 is not possible atm, because I run into some problems
and these need to be investigated a first.
Thx a lot,
Norbert
