Hey guys I just spent a whole day on a issue, where a service call in a page class ended in a "java.lang.LinkageError: loader constraint violation the class loader {...} of the current class, MyPage, and the class loader {...} for resolved class, MyService, have different Class objects for the type used in the signature"
What I did was totally stupid (at least in hindsight): I accidentally passed the page object to the service: MyPage{ Object onSuccess(){ return myService.doStuff(this); } } It's no suprise that that wouldn't work when accustomed to J2EE and remote stuff, althrough I didn't expect that to happen in T5.3. The whole point of this mail: DO NOT pass your page object to the service. Cheers Beat
