I also ran into this problem. I managed to get around it by
extending CheckboxCell to listen for the "click" event, instead of the
"change" event.
To do this, in my new class, I just overrode getConsumedEvents:
@Override
public Set<String> getConsumedEvents() {
HashSet<String> result = new HashSet<String>();
result.add("click"); // Listen for the click event
return result;
}
And then overrode onBrowserEvent copying the entire method, but adding the
"click" event:
@Override
public void onBrowserEvent(Context context, Element parent, Boolean value,
NativeEvent event, ValueUpdater<Boolean> valueUpdater) {
...
if ("click".equals(type) || "change".equals(type) || enterPressed) {
...
}
And it all worked! I have no idea if what I did will work for all
situations, so use it at your own risk.
