> It is expected that "<a4j:support event="onchange" immediate="true"/>" there will be no validation and a4j will set the "selected" attribute properly, but it looks like this does not happen - validation happens and "setSelected(boolean)" method is not being called.
> However, using "<a4j:support event="onchange" ajaxSingle="true"/>" solves the problem, but it looks like a "hack". It is said in the RF spec:
>  Note, that ajaxSingle="true" reduces the upcoming traffic, but does not 
> 			prevent decoding other input components on the server side. Some JSF components,
> 			 such as h:selectOneMenu do recognize the missing data in the request map value as
> 			 a null value and try to pass the validation process with a failed result. Thus, 
> 			 use a4j:region to limit a part of the component tree that will be processed
> 			 on the server side when it is required.
