Because of this, switching from plain ol' displaytag to EL is as easy as changing:
<%@ taglib uri="http://displaytag.sf.net"; prefix="display" %>
to:
<%@ taglib uri="http://displaytag.sf.net/el"; prefix="display" %>

oh, right! That seems ok to me, for just the reasons you mentioned. Since it is such a small extension, there really isn't a need to package it seperately, plus it'll be easier for the users to upgrade to the el tags without having to install any other files, except maybe the tld. I know that it was a bit confusing for me trying to get struts-el working as it was hard to find the documentation on their site and I didn't immediately realize that there was a seperate jar file for it.

Actually, I said:
<quote> I like the 2 TLDs and one JAR approach we're doing - especially since the current JSTL implementation is only 3 classes. </quote>
So I'm *not* advocating 2 JARs. That being said - if the EL implementation grows larger (i.e. 10+ classes) - it might be a good idea. I'm cool with either way though - it doesn't really matter too much.

This sounds like a solid idea to me. Also, I agree with Matt's suggestion of creating a displaytag-el.jar for the el enabled tag.

Well, my plans are to have a pluggable, user-configurable, expression evaluator.
In this way we can include an "old style" displaytag evaluator, an EL evaluator and, in future, maybe an OGNL evalutor. Users should be able to choose it in the properties file or to implement a custom evaluator...

I'm going to definitively kill this in the EL version of table tag... This means that the el tag will never work in replacement of the standard tag without at least replacing the sintax of the name attribute (usually a couple of {} will be enough to fix it).
Since al EL version has never been released, neither in beta, this is the right time to do it... I'm sorry for users who downloaded the snapshot waiting for a release with a similar implementation, but since I didn't see any comment on this absurd thing I'm pretty confident most people will not care about it.
Useful though it might be, I've been in contact with Matt Raible about using the OGNL expression and binding language (http://www.ognl.org) as a replacement for the expression language in displaytag instead of EL. OGNL supports extensions which make it a more robust EL than JSP EL.
Do you have any thoughts on this?
