radioGroup in DataView

[Jehan <je...@gmail.com>]

Dear All

I am using radioGroup example found at URL:
https://cwiki.apache.org/WICKET/using-radiogroups.html
when I am clicking on submit button then old/Dafault selected values are
printing.

Using following code(saveRoleAssignments method) I want to print user
selected radio button values (e.g., true or false)

for printing I am using info method.

Thanks
