Sorry, my response got munged by nabble, the param tags disappeared.
So pretend I have angle brackets where you see square brackets below:

 [param name="dictionaryId"]${dictionaryId}[/param]

I was able to update the href and formId via JavaScript and DOJO as
follows:

dojo.widget.byId('divId').href = 'myUrl';
dojo.widget.byId('divId').formId = 'myFormId';

This works fine as long as the form itself was not loaded infot the DIV
(divId). However, if myFormId is located in divId and was loaded into
the div via the initial ajax call, then it does not work.

Any ideas?

Thanks in advance,
Ken

Subject: [S2] Ajax DIV Question

I have a tabbed panel. I would like to refresh the contents of this tab
and am able to do so by publishing to the proper topic. However, I
really need to take it a step further and be able to dynamically specify
the formid and href attributes of the Ajax DIV in my JavaScript, before
refreshing it. Is there a way to do this?

If I cannot do this, then I guess my next option would be to use
multiple nested Ajax DIVs. I believe that this would work okay if I
could specify that these DIVs not preload. However, it appears that
this is functionality was not added until 2.1 and I am using 2.0.11.
Would there be another way to accomplish this?

Thanks in advance,
Ken

Set showLoadingText=false on the relevant tags/widgets.
It's a bug in Dojo in IE where it overwites the form with the loading
text prior to reading the values from the request.

THANK YOU!!!

That fixed the problem. Thank you for taking the time to share.

I hate not having a message for the users there though. Does anyone
know of a fix for this?

Thanks in advance!

S2 Ajax/Dojo is a plugin.

Dave

It isn't - DOJO is available as a plugin since 2.1.x
But there is no possibility to use the AJAX theme without DOJO right now.
There was an interesting discussion at struts-devel:

To the existing tags? Not even sure how that would work; JavaScript libraries are all pretty different.

As someone else mentioned there's talk on the dev list regarding future options. I have a (largely abandoned) Google Code project to build a jQuery plugin, but with the new talk I'm even less likely to continue working on it. There were, at one point, at least two other people who were pursuing jQuery plugins, but I don't know the status of those projects.

Dave

ya, i want to know how to create different module. this is because my current
work need to do that.
can anybody tell me how to create multiple struts configuration file??

I thought this was supported by this version of Struts 2 but I never use
the DefaultActionMapper so I maybe a problem does exist there.

To fix:
1 create a custom action mapper copied from DefaultActionMapper.java
[link below]
2. enable it in struts.properties or struts.xml : ie.
struts.mapper.class = com.PatchedDefaultActionMapper
3. Apply a patch to the dropExtension method that accepts blank
extensions. Here is the updated method:

/**
* Drops the extension from the action name
*
* @param name
* The action name
* @return The action name without its extension
*/
String dropExtension(String name) {
if (extensions == null) {
return name;
}
Iterator it = extensions.iterator();
while (it.hasNext()) {
String value = (String) it.next();
if (value.length() > 0) {
String extension = "." + value;
if (name.endsWith(extension)) {
name = name.substring(0, name.length() - extension.length());
return name;
}
} else {
// allow a blank extension
if (!name.contains(".")) {
return name;
}
}
}
return null;
}

Use a client-side library with a good Tree widget. Google javascript
tree widget treeview.

I mostly use this: http://developer.yahoo.com/yui/treeview/

The built-in struts2 tree tag isn't very good.

I'm pretty sure it's something else (unless your struts app is coded badly).

Try disabling any Anti-Virus/Firewall/etc. software before running the
test. Failing that look at your app server and memory usage.

Out of interest, which container and browser are you testing with and
how is the browser sending the JSessionID to your container?
Within the browser you can determine whether you are using the same
JSessionID or a new one by monitoring the raw requests. If the Session
was lost, you'd have a new JSessionID.

A redirect result and a redirectAction result are the same as far as the
browser is concerned. They both return a 30x http status with a location
header providing the next URL to GET. In the case of redirectAction,
the result calculates the URL based on the name of the action. In the
redirect case, the result uses the location value directly. In both
cases, the URL performs a GET to the new URL, including the JSessionID
if appropriate (if it's in a cookie, or included in the URL)

It is feasible that your JSessionID is indeed reset as the result of a
redirect if cookies are disabled and JSessionID is not automatically
appended to the new location by the container/struts2.

Jeromy Evans

I'm using Tomcat 5.5.23 and I tried with Internet Explorer 7.0 and Firefox
3.0.
Yes, I can do that, to monitor the raw http requests in Eclipse.

No, my cookies are enabled all the time. But if my JSessionID is not
automatically
appended to the new location by container/struts2 in case of redirect
action, why ?

Probably because cookies are enabled all the time.

I presume you're referring purely to client-side validation.

Struts2 includes a javascript file validation.js that includes most of
the logic. It contains a simple for-loop that searches for the location
to insert each validation message relative to the input. I think you'll
need to create your own version of validation.js that changes this
search algorithm.

The templates for the tags dictate the location of the validation
messages (divs or table cells). The controlHeader.ftl file imported by
all tags will need to be updated to the structure you prefer (ie. to
include the relevant div after the input). See the struts2 documents on
creating a custom template.

You may also need to edit the form.ftl file, or whatever, to make it
import your validation.js file instead of the default.

#2 sounds like a bug in validation.js. I recall there is logic in there
to detect if a validation message is already present and not show it
again. It was buggy and may only be fixed in 2.1.x.

If you're referring to server side validation, the repeated message
indicates the list of errors is not being cleared between invocations of
the same each, which implies to action is validated twice for the same
request or a new instance is not being created for each request (which
is bad, and only possible if you're using spring and have incorrect
spring config).

Hope that helps,
Jeromy Evans

Thanks for the reply Jeromy, appreciate all the extra info you've given
me. It's the client side validation by the way, so I'll go down the
controlHeader.ftl route and see how I get on.

Someone else (Gabriel) mentioned a Javascript bug, so I think you're
right. I'll check out the relevant code when I get chance

Thanks again

So, I understand that:
surveyResult.questionEntity="surveyResult.initialValue" (a String)
and you want to perform a nested evaluation:

eg.
interimResult = evaluate("surveyResult.questionEntity");
finalResult = evaluate(interimResult);

The s:property tag does recognise nested expressions. My guess is this:

<s:property value="#root.%{surveyResult.questionEntity}/>

which reads: evaluate surveyResult.questionEntity, then get the property
with that name from the value stack.

**BUT, I can't remember if #root is right, or #stack, or #context.stack
#top or something like that; whatever it is that refers to the value
stack directly. This may be visible for the config browser.

The map notation may be clearer

<s:property value="#root[surveyResult.questionEntity]/>

In the worst case, you can invoke a method directly to get the stack.

Hope that helps a little,
Jeromy Evans

PS. I don't think this is a good idea as it is may be vulnerable to
injecting OGNL expressions depending on how surveyResult.questionEntity
is set.

Hi Jeromy,

In short yes, I'm trying to do a nested evaluation. I screwed up the
description, but what you've described is what I'm trying to do. I tried all
the permutations you suggested plus more with still no joy. I've used the
reflection API as a backup but I'd prefer to use OGNL.

Any help from the OGNL gurus would be greatly appreciated.

Z.

Thanks Martin,

I understand that. But what I’m trying to do is take one parameter, evaluate
it and then evaluate the result.

For example:
I have a question bean with an surveyEntity attribute. The value is variable
and it may be 'surveyLong.initialValue'. I now want to evaluate this string
as an OGNL expression ie call getSurveyLong().getInitialValue();

I've done it using reflection, but reflection has a heavy performance
penalty and from what I've seen of OGNL, it doesn't.
