This was it exactly... Actually, upon further digging yesterday, I did notice that when I got rid of the scope-related problem, the error was complaining about a type mismatch (As you said, trying to stuff a String into a boolean primitive. Sure enough, when I looken in BaseTagHandler.java, disabled is a boolena primitive).

The problem is that you are passing a String to an attribute that requires a boolean. The documentation could certainly be more clear (you could submit a Bugzilla item if you like), but you will note that it states *true* and not *"true"* as an appropriate value. If you want 'readOnly' to be a String, you'll have to use something like this for the value of the 'disabled' attribute: <%= Boolean.valueof(readOnly).booleanValue() %> -- To unsubscribe, e-mail: <mailto:struts-user-unsubscribe@;jakarta.apache.org> For additional commands, e-mail: <mailto:struts-user-help@;jakarta.apache.org>
