Re: Fine Grained Access Control in Sturts

I don't have it memorized. I just bookmark the taglib docs and can quickly send a link to an explanation. A lot of questions could be avoided by simply looking in the docs first :-).

Thanks David.

I always feel bad when I ask a question that is in the existing
documentation.

For others (unlike David) who do not have the documentation
memorized, the "logic:present" tag will take a "role" attribute:

Checks whether the currently authenticated user (if any) has been
associated with any of the specified security roles. Use a
comma-delimited list to check for multiple roles. Example:
<logic:present role="role1,role2,role3"> code..... </logic:present>

(RT EXPR)

Thanks again.

Mike
