This sounds more like a security issue than a behavior issue. I expect
you can use any security framework for wicket (Swarm, Auth-Roles,
someone is working on integrating Acegi) to do this. but off course I
would suggest Swarm :) In this particular case it could be as easy as
using for instance the SecureTextField and defining the proper
principals for your usergroups.
You can find more about Swarm here
