Re: Iterate Problem
This is all kind of fussy. You have to get the id's and everything right, manage the bean names etc, etc, etc. You can forget all of that stuff and use the nested tags. Makes life 100% simpler for iterating and everything else. They've been in Struts since January. Just that not too many people put them forward to help the easy stuff, which they make even easier... Primer, tutorials and downloads... http://www.keyboardmonkey.com/next It sounds like a plug, but I've had no complaints from anyone who's using them. Arron.

RE: Iterate Problem
Hi, Mark: I am displaying task information in an HTML table using the iterate tag. In the table are a set of input fields that allow my user to modfiy the values of each task (in your case you may simply want to display the value as readonly text). By using the indexed = true attribute of the text tag, when you submit the html form struts will update each of the action forms accessible via the getTasks()/setTasks() methods in MyTaskActionForm: struts_logic:iterate name=MyTaskActionForm property=tasks id=task indexId=index tr td valign=top struts_html:text name=tasks property=name indexed=true / /td td valign=top struts_html:text name=tasks property=dueDate size=30 indexed=true / /td td valign=top struts_html:text name=tasks property=description indexed=true / /td /tr /struts_logic:iterate Hope this helps, Chris -Original Message- From: Galbreath, Mark [mailto:[EMAIL PROTECTED]] Sent: Friday, April 26, 2002 2:00 PM To: Struts (E-mail) Subject: Iterate Problem I sure seem to be having my share of problems with logic:iterate this week My form bean (EditCustomerForm) has a property that sets and gets a List of Customer objects.

what we did here is set up a Vector or something like that which holds the beans (each bean will populate one row in this table). Then set this Vector into your session/request depending on what you like, then in the jsp page, use logic:iterate to create the table rows so the number of table rows will be the same of number of the elements in the Vector you passed on.

I had a similar problem, where it helped composing the property-term to a

html:text property=%=pVal% /

By the way, do you have to have an array? If you make it a collection, you can
do away with the index altogether!

Hello everyone.
I am currently having some problems with iterating over an array of

In my action class I have put an array into the session object
(request.getSession().setAttribute(orderedsandwiches,...);)

I am trying to do this like this:

td
bean:write name=element property=name/

/tr

When I loop through the array using jsp snippets, I can print out the
contents of the array like this:
table
%
OrderBean []ob = (OrderBean[])orderedsandwiches;
for(int i=0;iob.length;i++) {
%trtd%
out.println(ob[i]);
%tdtr%
}
%
/table
The strange thing about all of this is that in another jsp page, I do
almost
the same thing and there this works without any problems.
Does anyone have an idea to solve this problem

Subject: iterate problem
Hello everyone.
I am currently having some problems with iterating over an array
of objects.
In my action class I have put an array into the session object
(request.getSession().setAttribute(orderedsandwiches,...);)
I would like to loop over these objects in my jsp page.
I am trying to do this like this:
bean:define id=orderedsandwiches name=orderedsandwiches/
table
logic:iterate id=element name=orderedsandwiches
tr
td
bean:write name=element property=name/
/td
/tr
/logic:iterate
/table
But when I try to do this, I get an exception like the following:
9-jul-01 14:21:07 GMT+02:00 Error HTTP
[WebAppServletContext(5325170,sandwich)] Root cause of ServletException
javax.servlet.jsp.JspException: Cannot find bean element in scope null

When I loop through the array using jsp snippets, I can print out the
contents of the array like this:
table
%
OrderBean []ob = (OrderBean[])orderedsandwiches;
for(int i=0;iob.length;i++) {
%trtd%
out.println(ob[i]);
%tdtr%
}
%
/table
The strange thing about all of this is that in another jsp page,
I do almost
the same thing and there this works without any problems.
Does anyone have an idea to solve this problem
