it seems to work fine.

With 2.1.8, you can use

But it still has a bug: see http://issues.apache.org/struts/browse/WW-3314

Hi there,
I've checked struts2 docs and this forum and have found no inside syntax
for
s:iterator tag to do:
c:forEach var='' value='${}' being='1' end='4'/
Examples in docs just show how to count from 1 to 5 ¿? I'd like to avoid
counting and using indexed property to access an iterator. The last
example
in docs doesnt seem to work if I replace this with the property/objet I
want to iterate.
I am sure struts2 team has thought of a way to do some partial iterator (I
can also do the full iterator and do a s:if to show only 5 values using
status.index, but doesn't seem a nice solution.
Thanks,
Ignacio

Re: s:iterator ¿begin - end?
I agree with you, I don't use JSTL at all except forEach because of
the few limitations of the iterator tag. I will take a look at it.

Hi,

Well... I have to iterate through a collection accesible in a struts2
Action. I can make that object visible to the page/request scope and then
access it from JSTL c:forEach; in fact I am doing that for dynamic images
as strugs2 has no IMG tag to use OGNL directly. Very painful when someone is
used to access the object from the tag itself. Moreover... I am really
trying to forget about EL and JSTL. I really don't find my self confortable
using 3 different expression languages / tag libs in my pages. I didn't have
to (in struts1) but maybe I have to accept that idea now.
Moreover, EL is obsolete when compared to OGNL (oh god... when I discovered
I could do #{people.size()} I just didn't believe it!!! Direct access to
methods. JSTL hasn't been improved for 4 (5?) years! Method access,
valuestack... and I am new to OGNL. Don't know 50% of its power!
More situations: I made my HTML designers learn JSTL. Now I have to make
them learn OGNL and I am sure they'll have problems with both things mixed.
Of course, I'd like new people in the company thinking about the
presentation layer just to handle one thing.
Why doesn't OGNL team focus on making it possible to forget about JSTL+EL
and just use OGNL for every thing? It nearly does and just because a
couple of minor glitches we can't. (Another example... s:a tag doesn't have
target attribute. I have then to use HTML tag directly, what forces me
to transfer the href data in the Action to an object in the page scope and
use EL where. Painful for something that should be straightforward.
Well... sorry for the long text. Please don't take me wrong. Just love
struts2 and would love to forget about old technnologies. I wish I had time
and knowledge to help on all this. Now I just can't.

Re: s:iterator ¿begin - end?
Ok, here is the Jira ticket:
https://issues.apache.org/struts/browse/WW-2984
I committed the changes to the iterator tag, here is how it works: New
attributes begin, end and step were added. They can be used by
themselves, or with List and Arrays, like:
s:iterator begin=1 end=5 step=2
...
s:iterator begin=5 end=1 step=-1
...
s:iterator begin=1 end=5 step=2 value=myList
...
s:iterator begin=5 end=1 step=-1 value=myArray
Things to consider (let me make sure that google gets this :)):
* When values is specified with begin, then value must point to
a List or an Array
* The end attribute is inclusive, just like in JSTL, if a List/Array
is used, end is optional, and it will default to the size of the
List/Array, or to 0 if step is negative.
* If step is negative, then begin must be greater than end
I think that covers most of the use-cases. Testing is welcome (I added
a bunch of tests to IteratorTagTest).
