We have a basic/example Wicket portlet implementation now for the User manager.
But we need to expand/extend that portlet to provide the full functionalitiy needed, as well as support for the new security Preferences and attributes model implementation of
JS2-869 and JS2-870.
Furthermore, the other security and Site, Page, Profiler etc. portlet also should be rewritten using Wicket so we develop a common Wicket framework as standard for all admin portlets.
Finally, the backed model used by Wicket should be abstracted such that a later replacement / further abstraction to use other backends like JCR or even flat XML storage is easy the incorporate.
