It spits out an error at nativeEvent.getType() which is as follows:

Any insights?
The events cannot be used async; you must retrieve all the
properties upfront before doing your DeferredCommand:
public void onPreviewNativeEvent(NativePreviewEvent
nativePreviewEvent) {
NativeEvent nativeEvent =
nativePreviewEvent.getNativeEvent();
final String eventType = nativeEvent.getType();
DeferredCommand.addCommand(new Command() {
public void execute() {
System.out.println(eventType);
}
});

Re: NativeEvent Get Type Issue
Hi Thomas,
Thanks for your response. The only reason I have the DeferredCommand
in there is to actually spit this out. If I don't defer it, my
application simply freezes as its spiting out this error as I move my
mouse around. So essentially I don't even see the println since this
preview occurs and crashes. My point is that the error still occurs
regardless.
Any other thoughts?
Thanks

NativeEvent Get Type Issue
This is a good one. Totally confused. I am porting over an application

at a later stage. The onEventPreview used to block the escape key.
