user_189510.ezm (zipped)I don't see what Ajax has to do with this... It sounds more like an HTTP
caching issue. Cree, if you do a page refresh, is the image updated
correctly? I haven't used the JFreeChart result, but maybe it's not
setting the right cache control headers.

user_189519.ezm (zipped)it does sound like a caching issue.. try this directive before your <html>
<%
response.setHeader("Cache-Control", "no-cache"); //HTTP 1.1
response.setHeader("Pragma", "no-cache"); //HTTP 1.0
response.setDateHeader("Expires", 0); //prevents caching at the proxy

user_189530.ezm (zipped)I don't use the Ajax theme or any of the Dojo integration but I assumed that
if theme=ajax on the submit button that it would be using Ajax.

> Hello
> I am having a difficult time designing and implementing an interaction of displaying and accepting user input of multiple records at once. I can create a collection of records, but records are complex, composed of other objects that are themselves composed of text strings that I want rendered as either simple html input boxes, checkboxes or radio. I have a sense that I need to use the iterate to get iterate over the total collection, but how do I record by record render the html input elements. Furthermore what do these look like to the action that will receive the post? A simpler version of this is being done on shopping carts a checkbox on each line, but that may be hard coded. Is the way I need it even possible with struts 1.1?
Without knowing anything about what your data structures look like, it's
hard to offer specific advice; are you working directly with record
sets? with business model classes persisted via JPA? etc.
At a high level, what you want to do is certainly possible. How easy it
will be will depend on what your data model looks like and whether you
have the flexibility to change it.
I would suggest you start out by reading up on how Struts manages the
mapping between model data and HTML forms, and especially how data
conversion works. Then build a simplified prototype that works with a
minimal data model and build up from there until you have something
representative of the end goal.
It will be easier to get help when you have specific questions you can ask.

I m using Struts2 (S2), not Struts1. In S2 there is a standard result

Thanks any way.

Turns out it is a problem in dojo 0.4.0 that is shipped with struts2.
I include my own build of dojo to solve the problem.

And I will explain why.
If I make any mistakes, please, tell me.
This is my struts2 tag:
<s:a id="AncorId"
showLoadingText="false"
targets="%{'linkattachedMainDocRow' + #document.count}"
theme="ajax"
href="%{#deleteDocumentAction}"
notifyTopics="/afterDeleteLaw">
Click me!
</s:a>
this is my JS code:
dojo.event.topic.subscribe("/afterDeleteLaw", _listeners, "test1");
var _listeners = {
test1: function(sourceId){
alert("sourceId");
}
};
Do you know what will happen? I'll tell you. test(sourceId) will be invoked
twice.
The first time sourceId = id of dojo anchor widget (AncorId)
The second time sourceId = response text (text which my action returned).
This is amazing logic:
The first time you get widget, that sends request, the second time you get
response and you don't have any opportunity to determine, which anchor
recieved this response!
Imagine such situation:
Inside <s:iterator> you make several <s:a> widgets, you generate unique
<s:url> for them and id attribute.
User starts to click on widgets, they all start to send requests and receive
responses. As you know, JS in not thread safe, it means in a few seconds you
get terrible mix of widgets and responses inside subscribed topic.
I've spent three days trying to solve it, the right solution is: do not use
dojo anchor tag, use jQuery or your own custom ajax functions.
Please, take into consideration, it's extremely hard to get on with
listeners, I was lucky and got an idea of using listeners inside
google.code. I still don't understand how it works.
As I understand, the idea of ajax tags is to simplyfy the work, not to make
it as complicated, as possible.

Attachment:
user_189518.ezm (zipped)Another option is to read the documentation, which indicates that the JavaScript function will be called twice (although it's better-stated in the 2.1 docs), once getting the id, and then again on success or error, with the HTML result.
http://struts.apache.org/2.0.11/docs/ajax-tags.html#AjaxTags-anchorTag
When you specify a handler you can use closure to include the ID of the widget you're creating the handler for, but that's a JS issue, not Struts. JS has a few major warts (yeah, thanks for binding "this" all goofy, JS) but it's very powerful when used with skill.
If you're interested in programming JS I'd recommend the Crockford videos. Well worth the time, and it'll improve your programming in other languages as well.

That's agreed!
What do you recommend? I have Kurniawan's "Struts 2 Design and Programming"
and Roughley's "Practical Apache Struts2 Web 2.0 projects" and "Starting
Struts 2". None of them go into any kind of detail about this section of
things (which is understandable since (a) it seems to be an edge case, (b)
it is a somewhat moving target and (c) the documentation on-line is 'less
than optimal')

True. The Struts 2 in Action book goes into the next level detail:
http://www.manning.com/dbrown/excerpt_contents.html
but still doesn't cover exactly what you're trying to do. I know others
works are in progress but not the details or schedules.
You may need to delve into the source near the DefaultActionMapper and
ParametersInterceptor variations to understand how it ties together.

Thanks. I'll order that and see where it takes me (although it gets a
panning on Amazon UK - reviews on Amazon.com are more favourable).

Already been there all morning :o}
Thanks a lot for all the advice and discussion. It's been really helpful.
I think that - for now - I'm going with a straightforward wild-card mapping
coupled with a single-set property in the Action which appears in my
empirical testing to guard against "form parameter over-riding" of the
property.
The down-side is the configuration overhead. My separate actions have
distinct results so, although I have a dozen actions that need to share this
behaviour, I have to configure them separately to do it. If I build it later
into an Interceptor then I will be able to just add that to the default
interceptor stack for a package/packages so I may take that route at a later
date.
I *think* that sounds sensible, but I've stared at too much code, struts
'documentation' and Netbeans screens over the past few days to be sure.
Later,
Andy

That's one explanation.
>> So, scenario is like this:
>> [...]
I am unable to duplicate the inability to test session variables for non-existence/null.
If I have an action implementing SessionAware (properly), set "foo1" into session, and do not set "foo2" into session, the following tests work:
<s:if test="#session.foo1 == null">
...
<s:if test="#session.foo2 != null">
...
They continue to work if I go through multiple actions using the exact same JSP to test for their presence/non-presence.
It is likely you are doing something wrong. I suppose that means you'll need to post the relevant SessionAware implementation, the code that sets the session variable(s), any action code in the application path that could modify session variables, the JSP that currently doesn't work, and any variants of the JSP code you've tried that also hasn't worked.

Yes, I tried with this, but session variable is not found.
I think that you didn't understand what is my scenario. I have implemented
SessionAware interface for both of my action classes and that works
perfectly in the case of jsp's that are connected to that classes.
But in this case, I have this:
MyFirstActionClass -> show first.jsp -> user click on link ->
MyFirstActionClass.method where I set session variable
(getSession().put("variable"); -> show second.jsp -> user click on some link
-> MySecondActionClass.method is called to return some results -> show
third.jsp with those results, and in this page I test if my session.variable
is present, but there is not !! But, my variables that are set in
MySecondActionClass.method are present in session for third.jsp!
What is the problem ?

It seems that my session variable is deleted somehow when first action method
of the second Action class is called:
MyFirstActionClass -> show first.jsp -> user click on link ->
MyFirstActionClass.method where I set session variable
(getSession().put("variable", new Boolean(true)); -> show second.jsp (here I
see my variable) -> user click on some link ->
MySecondActionClass.method->third.jsp (here I don't see my variable).
I should note that in MySecondActionClass.method I don't clear session or
something similar, I just add remove some other variables and set some new.

Yes. I started my project with Tomcat in Netbeans and I have not set context.
The url look like:
http://localhost:8080/index.action
When I set namespace : namespace="/manager" the url look like:
http://localhost:8080/manager/indet.action
and the server return me HTTP Status 404.
Then I set context for Tomcat in Netbeans and it work perfect. The url then
look like:
http://localhost:8080/project/manager/indet.action
goodbye

The default from struts-default.xml is:

so you will need to plug your implementation.

Execute() method:
------------------------------------
@Validations(visitorFields = {
@VisitorFieldValidator(message = "Default message",
fieldName = "surname",
appendPrefix = false)
})
setSurname() method:
------------------------------------
@RequiredStringValidator(message="Validation error",
key="validate.surname")
I'm guessing that I'm not supposed to use the visitorFields annotation
with the others. Was giving me some really strange behaviour. Will hunt
for some better examples...

Do you have a setSurname(String) method? Without it, Struts can't pass
the input data into your action.

If you do have the setter in your action and you're getting this, do you
have any action errors/messages showing up when you get returned to the
input page?
