once again, i have to answer the question myself! at first: would anyone PLEASE write an guide for using the jsonprequestbuilder!!!! it´s damn annoing the find out everything by try and error.
about my problem: the name of the callback method for the jsonp request changes whith every request. when you do the first request the name is: __gwt_jsonp__.I0.onSuccess for the second request: __gwt_jsonp__.I1.onSuccess for the third: __gwt_jsonp__.I2.onSuccess ... that definetly make sense, BUT is nowhere noted in the documentation!!!!! and - belive it or not - you can see this little change from one request to another very hard when you look at a couple of requests.
