Is there a way not to put the input field twice with two different logic:present tags ?
Does anybody have an idea on how to change display based on the role (and maybe something else) ?

You can use the logic tags to do something like this:
<logic:present role="admin"> <html:link page="/admin/Admin.do">Admin</html:link> </logic:present>
This assumes you are using a security mechanism where request.isUserInRole("admin") will return true when the user is in that role. For that to work, you must use container-managed security or a filter-based solution like http://securityfilter.sourceforge.net/.

Does anyone have any thoughts on fine grained access control in Struts?
Struts enables access control based on actions (see "Struts in Action", Husted, et. al., pp 550-553), and most application servers can protect resources based on realms/roles.
But what about display options based on roles. For example, if you only wanted an "Admin" link to appear if the user was an administrator, what would be the best way to do this?
You could make the "role" an attribute of the user object and then do a logic test for the appropriate role. Or it might be even better to write a logic tag that takes the user role as an attribute. Any thoughts?
Thanks for your consideration.
BTW. The Husted book is a very good book.
