Hi, I am using the Cache taglib from Jakarta Taglibs.
On the documentation page: http://jakarta.apache.org/taglibs/doc/cache-doc/ there are examples of attributes having RTExpressions (one example is key="${user}.${verbosity}"), but the tld says none of the attributes can be RTExpressions (you can see this on the same page, the 'Runtime Expression Evaluation' column always says 'No'). So obviously, when /I/ use key="${user}.${verbosity}", it doesn't work. So... 1. Am I missing something? Is there a logical explanation to this apparent contradiction? 2. I have, myself, written several taglibs, and have always let all the attributes be runtime expressions, as I can't see the point of not letting the user use rt expressions if they want to. Why can't all attributes of any taglib be a RTExpr? Why ask the taglib author to specify this in the tld? 3. Just out of curiosity, if I wanted an attribute value to be the literal string "${user}" (not the value of the "user" attribute, but a 7 character string starting with '$' and ending with '}'), and if the attribute doesn't accept rt expressions, would it be possible? I know you could escape this with ${$}{user}, but ${$} is itself a runtime expression so it can't go in a non-RTExpr attribute. Thanks for your help. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
