> I'm evaluating Struts2 to use for our upcoming web app. I used WebWork 2.1.7
> on our last project, and really liked it, so I'd like to use Struts2 for the
> new one, but I'm running into a very strange problem.
> I've distilled the problem down into a sample application. There is one
> action, and one jsp view template. The view contains some EL (eg -
> ${firstName}) and some Struts2 JSP tags (eg - <s:property value="firstName"/>.
> The first time I hit my page, everything works fine.
> However, if I keep reloading the page, the EL stops working. Nothing gets
> substituted into the page for the EL statements. The JSP tags continue to
> work.
> I've tracked it down to this: it is related to the javascript I'm including.
> I don't believe it matters what's even in the javascript files. If I don't
> have any <script> tags in my <head>, then everything works fine. If I start
> to add <script> tags, the EL stops working.
> The sample project, as packaged up, should not work consistently. If you
> comment out the line including the prototype.js script, it will start working
> consistently. (note that the prototype.js file is actually empty)
> If you comment out the script line including prototype, it will work. If you
> leave this line in, it will not work. (note that the prototype.js file is
> empty)
> I will be attaching a sample project which demonstrates this. I'm working on
> OS X, with JBoss. I gave this .war file to a co-worker, and we saw the same
> behavior on his WinXP machine running Tomcat. So I'm hoping that you will be
> able to see this as well.
> I'm just really confused at this point, I don't understand how having Struts2
> write out a <script> line to the HTML would keep the EL from evaluating.
