quickstart

> 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.
