Yes, it sure should. And the first line should be:

I don't think you can pass parameters in JSTL, at least not yet. But
you could, in your action, call getModelList passing the String you got
from the request, and then when you forward to the JSP, iterate over
that Collection.
If getModelList returned a Map, or you made a getAllModelLists method
that returns a Map, you might have this:
c:forEach items=${myBean.allModelLists[theRequestParam]}
item=${model}
c:out value=${model.name}/
/c:forEach
That depends on how big they are, and whether they change for each user.
If you models are fixed and change infrequently, you might be able to
put a big Map in Application scope and use it across the entire webapp.
Out of curiosity, what class is getModelList from?

c:set var=modelListProp value=modelList(${param.paramName})/

bean:define id=modelList name=bean property=%= modelListProp %/
Which should give you a bean called modelList that holds your collection. This

necessary.
I have got the nested tags to work properly. The

something slightly wrong when I tried.
Remember to have
getMap(String key)
and
setMap(String key, Object value)

RE: logic:iterate question
You'll have to use indexed property getters. I believe you'll also have to put vTwo
into your form bean so you can take advantage of the indexed property getter.
Like so:
logic:iterate id='item' name='vOne' indexId='idx'
logic:notEqual name=%=idx.intValue()% value=0
,
/logic:notEqual
bean:write name='item'/:bean:write name='myForm' property='%=vTwo[ +
idx.intValue() + ] %' /
/logic:iterate
I used single quotes around the attributes here because of the double quotes within
the JSP expression, b.t.w.
Note that this would be a lot cleaner if you used a Tuple object (named whatever you
like) that contained (number,letter) fields and use a single Vector of these objects:
logic:iterate id='tuple' name='tupleVector' indexId='idx'
logic:notEqual name=%=idx.intValue()% value=0
,
/logic:notEqual
bean:write name=tuple property=number/:bean:write name=tuple
property=letter /
/logic:iterate
bean:write name='responseProcessForm'
property='%= msgCode[
+ index.intValue() + ] %'

Since you can access specific item in a list through something like
this:
bean:write property=vTwo[0]/
You should be able to do what you want through a scriptlet:
ie
bean:write property='%=vTwo[+idx+]%'/
We use this trick all the time ( and I gleaned it from this fabulous
list in the first place.)

The Facility object contains an array of PhoneNumber objects. My question is: Using struts tags, is it possible to pull the PhoneNumber[] array out of the Facility object and then iterate through them? If the PhoneNumber array were in the request by itself, then the iterate tag would work fine, but the array needs to pulled out of the Facility first.

The nested framework from Arron Bates is the ticket (see www.keyboardmonkey.com). With it you could %-- Form using a Facility bean --% nested:iterate property=phoneNumbers nested:write property=areaCode/ /nested:iterate Of course, the property attributes assume the corresponding getter methods. The beauty of this is that you can go any number of levels deep.

I'm trying to reference a bean which returns a String[] but I only want one of the values in the array. The indexID is working but it isn't getting passed to the bean:write tag corretly. It throws a java.lang.IllegalArgumentException: Invalid indexed property 'attributeNames[]' If I passed the bean a hardcoded index value, it works. I can also print out the value of the index.

Hi , From what I understand you want to create links for each headline and pass the head line as a parameter. So inside the logic:iterate tag U should put : logic:iterate. jsp:useBean id=info class=java.util.HashMap/ %info.put(HeadLineID, X); % html:link page=/details.do name=info Headline /html:link /logic:iterate U can replace the one line of code with jsp:setProperty of the bean info It worked for me.

I have a similiar question, but this time with a button
Every row will have a show action. With a link there is no problem (using
the method described) but with
a button I have a problem since I cant replace the onclick event with a
parameter.
html:button onclick=go('show',bean:write name=loop

this should become input type=button onclick=go(show,1)
