Found it. It seems I have been blind during debugging. I changed an object without creating a new instance and stored it in an ArrayList. Not really surprising that both markers had the same position ;-)
The second error still exists. What I found out so far is that it only occurs in code server mode (parameter: "gwt.codesvr=127.0.0.1:9997"). If I compile and do not use the code server the error doesn't occur. Thanks again. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
