I have a question about the detail portlet. After change to "edit your
information" on detail portlet, is there a way that I modify the "editable"
status for certain attribute based on the value from other value? E.g. if
the user is from USA, the user can modify his/her SSN. If the user is not
from USA, the SSN field should become not editable. If so, where shall I
set the logic? In the data abstract layer?
