gwtchosen 3.0 NPE issue with clear() and update()

[Rogelio Flores]

I've been using gwtchosen successfully. With code that runs fine in gwtchosen 2.1, it now fails whenever I call chosenListBox.clear() or chosenListBox.update() with the following (same stacktrace for both):

ERROR: Uncaught exception escaped

com.google.web.bindery.event.shared.UmbrellaException: Exception caught: null

at com.arcbees.chosen.client.gwt.ChosenListBox.clear(ChosenListBox.java:323)

at com.arcbees.chosen.client.gwt.ChosenListBox.clear(ChosenListBox.java:317)

Is this the same issue as

https://github.com/ArcBees/gwtchosen/issues/269 ?

Is there a workaround?

Hi Rogelio,

I think it might be a mix between https://github.com/ArcBees/gwtchosen/issues/269 and https://github.com/ArcBees/gwtchosen/issues/271.

This will be fixed by https://github.com/ArcBees/gwtchosen/pull/279 and/or https://github.com/ArcBees/gwtchosen/pull/280. I've added a test for that in #280

Please try the new 3.1-SNAPSHOT after we merge those 2 pull requests.

I can confirm that 3.1-SNAPSHOT solves this issue.

However, there's another issue. When I set options programmatically like this:

chosenListBox.addItem(displayName1, id1);

chosenListBox.addItem(displayName2, id2);

and then set the first one to be selected:

chosenListBox.setSelectedIndex(0);

the widget displays as if there is no selection; that is, gray text and down-arrow (see image below). Trying calling the update() and/or forceRedraw() doesn't solve the issue. If you know of a workaround (other than changing the text/arrow color via css), let me know. Thanks.

Thanks for reporting. I've opened a new pull request to address this. A new snapshot should be available in the next few days
