Radio uuid is calculated wrongly for heavy instalations.
--------------------------------------------------------
Key: WICKET-3175
URL: https://issues.apache.org/jira/browse/WICKET-3175
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.4.13
Reporter: Michał Letyński
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.
