Rendering and styling done as required in JIRA Description: screenshot-01.png. That's the easy part. Next is the more difficult task of enforcing mutual exclusivity.

Suggestion from meeting (by Mark): Grouping could be logical as well, not just within container.

Mutual exclusivity done: video.

Logical grouping done similarly to "spread" layout of 1.8 <ice:selectManyCheckbox>. (Adding "group" attribute to checkboxButton: screenshot-02.png.)

Apart from new code to do grouping and mutual exclusivity, no change was made to the existing checkboxButton code whatsoever. Therefore its behavior is exactly the same as before.

In showcase -> buttonGroup - Overview (revision #37856/ 382388): console error when choosing radio buttons in Firefox and IE (not an issue in Chrome).

FF23:
TypeError: g is null
http://localhost:8080/showcase/javax.faces.resource/coalesced.js.jsf?ln=ice.core&dgst=o87tz3
Line 5780

IE10:
SCRIPT5007: Unable to get property 'type' of undefined or null reference
coalesced.js.jsf, line 5780 character 984

These errors are actually caused by the radioButton component, as they can be reproduced also on the ace:RadioButton Overview and Custom Style demos in showcase.

Committed fix for last issue at revision 38263. Removed some unnecessary lazy-loading code that was causing the error.

Verified fix for last issue with rev# 38267 in Chrome/FF23/IE10 using showcase sample and radioButton test app.

rev 40068 to 3.3.0 mtce branch and 37373 for QA on repo

Re-opening because of the following errors found in showcase (Firefox only; using Jenkins EE 3 trunk Build # 425):

1) buttonGroup > Overview:
Clicking inside the form with the buttonGroup and tabbing through triggers browser console errors when checkboxes gain focus:

TypeError: e is undefined
http://localhost:8080/showcase/javax.faces.resource/coalesced.js.jsf?ln=ice.core&dgst=mhw7pq
Line 38498

2) checkBoxButton> Custom Style: similar error when clicking in first checkbox and then tabbing through.

The browser console error is still reproducible in Firefox with EE-3.3.0-maintenance rev.41200:
TypeError: c is undefined
http://localhost:8080/showcase/javax.faces.resource/coalesced.js.jsf?ln=ice.core&dgst=zg6ihb
Line 466

Make sure to pass in the event object to the ice.ace.checkboxbutton.onAriaKeypress method when wring the keypress event callback.

The trunk was fixed by ICE-9728.

Testing with EE-3.3.0-maintenance branch rev. 41221/FF29, Chrome35, IE10, no JS errors have been found.
