I have started to use JSTL this week. I simply love it !!!
However, I have one small problem that I cannot seem to get working.
Here is a snippet of code that works fine:
c:forEach items=${dynaCWWHistoryForm.map.historyItems} var=
historyItems varStatus=status
tr valign=top
td id=cc:out

I think ${status.index} in place of s_SOMETHING_HERE would work fine

The expression is never evaluated. The output is:
select name=historyItems[2].scheduleTypeId
onchange=addTableRow('historyTable','sc:out value='${status.index}'/')
class=dropdowns2
Are you using the EL version of the struts tags?

You choose to use the struts EL tags by a) using the struts EL tld (like
struts-html-el.tld) and b) by having the struts-el tag JAR file. I don't
know if they come by default with the latest release or not; you'd have
Okay... I am not using the Struts EL taglibs.
Should I be using them?

I think Dave's got it. Use the struts-el tags if you want to have EL
expressions instead of RT expressions (%= ... %)
If you want/have to stick with RT, then you'd need this instead of
${status.index}

I think you should. Makes the code a lot cleaner. Remember if you are
using a JSP2.0 container (ie Tomcat 5), just use the regular html tags
(not the el ones). (Then
Okay...
I tried the following:
html:select name=historyItems property=scheduleTypeId indexed=true
styleClass=dropdowns2
onchange=addTableRow('historyTable',
's%=((javax.servlet.jsp.jstl.core.LoopTagStatus)
pageContext.getAttribute(status)).getIndex()%')
html:optionsCollection
I think that with RT the attribute is all expression or no expression.
so try :
html:select name=historyItems
property=scheduleTypeId indexed=true
styleClass=dropdowns2
onchange=% = addTableRow('historyTable', 's +
((javax.servlet.jsp.jstl.core.LoopTagStatus)
Umh... I am now getting this error: Attribute addTableRow( has now value.
I have downloaded the Struts 1.2.4 and noticed that there is a lib
directory and then there is a contrib/lib.
What is necessary to use the Struts-EL tags?

The error is suggesting that it can't find an entry for status in the
page scope of your page. Do you still have the c:forEach in there?
If you have the scope attribute, make sure it's set to page. Otherwise
you'll have to replace pageContext with request, or session depending on
