Using the showcase sample with MyFaces 2.1.3, several demos that use the h:selectOneRadio component can fail with errors:

ace:menubar:
Effects:
Internet Explorer / Firefox: When changing 'Transition Effect' multiple times the radio button becomes unselected and a validation error is seen.
Haven't seen this myself and couldn't reproduce exactly as described. There were some intermittent client side errors in the console but not on every click:

[window] configuration not found for INPUT
[window] configuration not found for INPUT
[window] Error [status: clientError code: undefined]: undefined
exception ? console.er...ror(formatOutput(category, message));
'cannot find enclosing form' when calling method: [nsIDOMEventListener::handleEvent]
[Break On This Error] originalHandler.handleEvent(event);
