Poor Pat asked Mark Roth of Sun to not jump in a take peoples syntax. The problem is that once JSP (via JSTL) says "${foo} will resolve to X". Other frameworks don't get a look in. Pat was worried that #{..} would be eaten up yet and OGNL uses that for maps and such! Matt Raible was on the chat session with Mark Roth and asked these questions: I asked the following question as part of the chat: Is there any chance that web frameworks (like WebWork) could override the default settings for the EL? So ${myForm} can look in areas other than page/request/session/application scope - i.e. WebWorks's ValueStack? It looks like this *is* going to be a part of JSP 2.1 - from Mark Roth: JSP 2.1 is not only concerned about supporting Faces. We also want to support other frameworks. the new unified EL 2.1 API supports the concept of a pluggable VariableResolver (similar to the one that Faces has) which allows you to plug in your own logic for how variables like ${myForm} are resolved. So yes, this will be supported. Imagine that? Pluggable Resolvers? Now we can live nicely together. Note to Self: Write a nasty revolver which does weird things with ${} and get it somewhere to confuse people on projects: Why does ${foo} print out SO YOU WANTED SOME FOO DID YAH! instead of the value?
