Re: Struts 1.1 iterate woes
That works, thanks.
But does anyone have a Struts EL version? I prefer to go that route.
Thanks Victor

RE: Struts 1.1 iterate woes
If "${index}" is not evaluating, then this is not a Struts problem.
It's an issue with the container you're using and your configuration of
it.
For instance, you appear to say you're using Struts-EL. Do you have the
correct taglib directives to use Struts-EL as opposed to Struts? What
container are you using?

Re: Struts 1.1 iterate woes
Thanks Addy, but I am not clear on your syntax. What is your bVO.lines?
Remember my list is in my form. Also what is bLine? Not sure where my
variables correspond

Re: Struts 1.1 iterate woes
I have to admit I always have trouble dealing with the iterate tag. I
recently rediscovered how easy it is to do these iterations using the
nested tags. Have you tried them? Maybe something like this would
work for you:
Send
I don't know if it's considered "best practice" to also surround the
form with , but I've tried using the basic
and it works fine, too. The result is code I can actually understand.
:)
If you want to stick to the html tags, take a look at the example in
http://wiki.apache.org/struts/StrutsCatalogLazyList

Struts 1.1 iterate woes
We are trying to use in a JSP to access items in a list
stored in the Form Bean by the Action class but we can't seem to get the
syntax right.
I am getting an error meessage from PropertyUtils that displays the index as
'${index}', which indicates that that struts el expression is not resolving
to an int.
Here is my exact syntax. The form and action are described in more detail
below.
Send
I have created several Test classes to help me understand the flow...
The form is an instance of TestForm exends ActionForm and its form name in
struts-config.xml is "testForm". (This is the named form for the action.)
TestForm has one property: java.util.List list with accessors public List
getList() and public void setList(List list).
List is always a List of LineItem objects where LineItem is a simple
JavaBean with properties
String id (public String getId() and public void setId(String id)), String
description (public String getDescription() and public void
setDescription(String description)) and boolean isChanged (public void
setIsChanged(boolean value) and public boolean getIsChanged() )
The Action (TestAction extends Action) "execute" method creates a List of 5
LineItem objects and stores that List into the form by calling
((TestForm)form).setList(list), then forwards to the jsp (test.jsp)
In the jsp I would like to iterate through the list to perform the
following:
display the id (as html read-only text) and the
description (as html:text) of each line item,
then use JavaScript to change the "isChanged" property (in a hidden field)
when the onchange event is triggered.
I have tried several different syntaxes. I also tried using arrays instead
of List's. I also specified the type of the LineItem class explicitly in the
form element. I tried each of the "html:" and "bean:write" lines above one
at a time to see if any would be successful, but they all produce that same
error. I have combed the web for a good example of how to accomplish this,
but I couldn't find anything that handled things in a way that would work
for us.
Can you tell me what I am doing wrong and how to accomplish the access?
Thanks/Victor
