No, just like the compiler doesn't generate an error for other cases where it's guaranteed you'll have an NPE at runtime, even without jsinterop. If your GwtNativeUtil.getBoundingClientRect(element) wasn't JSNI and returned 'null' (for example, a typo where you write 'if (element != null) return null;' instead of 'if (element == null) return null;' and somehow the compiler can infer that 'element' won't ever be 'null'; or of course the reverse: without the typo and the compiler somehow can infer that 'element' will always be 'null'), then it'd generate the same code (just without the call to getBoundingRect here). -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
