> On big page's autoIndex for Page is getting bigger. Autoindex is used for radio buttons to identify its value (return "radio" + uuid).
> Uuid is a short primitive type and when its bigger then 32767 it become negative. Its a problem for radio button getValue code which looks like this:
> 	public String getValue()
> 	{
> 		if (uuid < 0)
> 		{
> 			uuid = getPage().getAutoIndex();
> 		}
> 		return "radio" + uuid;
> 	}
> In such case new uuid is set and we will get an error after submit this radio:
> "WicketMessage: submitted http post value [radio-32768] for RadioGroup component [0:form:radioGroup] is illegal because it does not contain relative path to a Radio componnet. Due to this the RadioGroup component cannot resolve the selected Radio component pointed to by the illegal value. A possible reason is that componment hierarchy changed between rendering and form submission."
> Problem can be solved by changing short primitive type to Short object and checking its not null instead of <0.
