anyone could give me some hints on what's wrong?
Do you think the fact that I have both struts-taglib and struts-el in
my
Lib directory could cause problems?
No, because el actually depends on taglib -- you have to have taglib to use el.
If you're also using JSTL, I would always advise using <c:if>
whereever it works -- not that this shouldn't be fixed if it turns
out to be a bug.

Hello all,
I have an app which is using struts 1.3.. I wanted to 'replace'
existing struts tag with struts-el tag.
So I downloaded struts-el-1.3.0-dev and put it into my jar, (along with
struts-taglib-1.3.0-dev)
I have declared taglibs in web.xml, and I wrote a simple page which uses
Struts-el inside a logic:tag
And, to my surprise, it did't work....
Basically I have an attribute of type collection in my HttpSession, and
I was trying to access it from the page using
<Logic:present name="${sessionScope.results}">
for doublechecking, I wrote a scriptlet code that was trying to get the
'results' attribute from the session, to see that if it was actually
there..
and it was there....
Even the c:forEAch loop that uses JSTL to get that attribute works
fine..
for providing as much info as I can, here is my web.xml
