Dynamic form fields with s:div and ajax
Hello,
I am trying a common scenario, where I want to dynamically create form
fields and either add or remove some fields. The fields are a List of
objects. I using the following approach described in short:
AddObjectAction:
ListMyObject myObjectList;
prepare(){if == null (3x) add ... else add 1x}
String delete(){ myObjectList.remove(int listPostion) }
home_jsp:
s:form id=form
s:textfield key=anotherField /
s:div id=objectsDiv theme=ajax href=%{getListOfObjects}
formId=form /s:div
/s:form
addObjectAction-success.jsp:
s:iterator value=myObjectList status=status
s:url id=deleteObject[#stat.index]
param name=listPosition value=#stat.index /
/s:url
s:textfield key=myObjectlist[#stat.index].value1 / ..
s:submit formId=form value=-
href=%{deleteObject[#stat.index] /
/s:iterator
This works, but does not refresh the div objectsDiv. Using target does
not work because objectList does not get onto the request, without
target the objectList is on the request. I tried to set the objectList
as a param to s:url deleteObject, this kind of works but results in a
param intercepter exception (haven't tried a custom converter yet).
When having the div put the fields from formId=form onto the request
it only puts the fields onto the request that itself does not hold. In
example only the 'anotherField'.
I think this should work this way. Why does setting target result in
removing the myObjectList on the request? Why does s:div formId not put
the fields on request itself holds?
Many thanks in advance

Re: Dynamic form fields with s:div and ajax
Hello Gainty,
thanks for your reply and effort!
I do specify the href as s:url id=getListOfObjects action=addObject
/. Sorry I left that out. This calls the AddObjectAction, which
populates the List of objects in the prepare method. This works greate!
But I simply cant target the div with the action in the div.
In your doc you use a static jsp where I use the Action to render the
jsp and initialize a List of objects. Than I want the same div and the
same Action to render the same jsp with the previously initialized List
of objects and in the action do something to the List either delete or
add an object. And either way I try its not working.
Targeting the same div (in your doc 'one') results in not having the
list on the request. Using the formId results in not getting the the
list on the request. I know it works if I leave out the target on the
div (in your doc 'one') but still the div needs to be rendered again to
make it visible. It works when I target a different div. But how do
override the other div.
regards

you would either need to specify where the href value is coming from
s:div
id=one
theme=ajax
href=%{test}
OR
use the supplied value from property
Output:
Firstname :

javascript in returned jsp through xhr
Hi, I am a little stuck here. A action loads a jsp into a div. For this I use the ajax theme (dojo) and a form submit with target. Works fine. The Problem ist, that the jsp returned by the action has javascript in it. Its the jcalendar. Having this jsp load normally the calendar works fine, but not in div. To solve this I tried executeScripts option, but that did not work. I searched and found out that eval might help, but I simply dont know how this could help. Any hints would be greatly appreciated.

Re: javascript in returned jsp through xhr
---BeginMessage---
Dear Gainty,
vielen Dank for your reply. I am very sorry but I cant supply you with a
url. What I load into the div is the following:
%@ include file=/common/taglibs.jsp%
s:form id=traitForm method=post
s:textfield id=form_start theme=xhtml cssClass=text medium /
button id=button_start type=button class=button../button
s:submit key=button.next /
/s:form
script type=text/javascript src=c:url
value='/scripts/prototype.js'//script
script type=text/javascript
src=${ctx}/scripts/calendar/calendar.js/script
script type=text/javascript
src=${ctx}/scripts/calendar/calendar-setup.js/script
script type=text/javascript
src=${ctx}/scripts/calendar/lang/calendar-${pageContext.request.locale}.js/script
script type=text/javascript
Form.focusFirstElement(document.forms[traitForm]);
Calendar.setup(
{
inputField : form_start, // id of the input field
//ifFormat: %m/%d/%Y, // the date format
ifFormat: Calendar._TT['TT_DATE_TIME_FORMAT'],
showsTime : true,
singleClick : false,
button : button_start// id of the button
}
);
/script
I use the following technique to load it into the div:
s:form id=form_TraitPage action=selectTraitPage
namespace=/ method=post
s:radio list=traits listValue=getText(class.name)
listKey=class.name name=traitType /
s:submit id=submitSelectTratiPage theme=ajax targets=traitDiv /
/s:form
s:div id=traitDiv theme=ajax
cssStyle=width: 100%;
loadingText=getText('Loading')
/s:div
The selectTraitPage-action returns the jsp with the jcalender. The
problem is, that clicking the button than does not result in a calendar
view. I can use it when loaded not in the div.
I simply dont know why and are very grateful for your help. I believe
its a matter, that the imported calender.js and/or prototype.js (which
is needed for the calendar) can bind to the button!? So it fails.
Thx,
Henning

Hibernate UserType and OGNL
Hi,
I am trying to implement a hibernate UserType for all the monetary
amounts in my application. I follow the example given in Manning - Java
Persistence with Hibernate Chapter 5.3 .
I am having difficulties to set and retrieve the value from a jsp due to
a lack of understanding how this is handled. I assume it is related to OGNL.
Basically I am trying the following:
addBid.jsp:
s:textfield key=bid.amount / ( also tried: s:textfield
key=bid.amount.amount / )
Mapping:
@org.hibernate.annotations.Type ( type=
com.app.persistence.MonetaryUserType )
@Column( name=amount )
public Monetary getAmount() { return amount; }
and Monetary beeing:
public class Monetary implements Serializable{
private final BigDecimal amount;
private final Currency currency;
public Monetary(BigDecimal amount, Currency currency) {
this.amount = amount;
this.currency = currency;
}
public BigDecimal getAmount() { return amount; }
public Currency getCurrency() { return currency; }
I am getting either a field error or with bid.amount.amount :
ERROR [btpool0-2] InstantiatingNullHandler.nullPropertyValue(110) |
Could not create and/or set value back on to object
java.lang.InstantiationException: com.app.model.Monetary
What am I doing wrong? What is this
InstantiatingNullHandler.nullPropertyValue and how to trac it down?
Thanks and kind regards

Re: [OT] What do you code today?
Wes Wannemacher schrieb: I've been quiet on this one, but since I finally had a breakthrough today, I feel like talking about it :) I started a pet project that I've been toying around in my head for a while. As a parent, I coach a few elementary and junior high sports. It is a volunteer thing, and if offered pay, I would refuse it (the schools need the money more than I do). The biggest complaint that parents have though is that they feel like we don't provide enough information, etc. Sometimes I want to tell the parents that complain to shove it :), but as a parent myself, I feel the same way about teachers, so I try to do a better job each season. Since I setup a wordpress/phpBB site a while back (which I haven't been too diligent about updating), I thought about doing something similar. Having dealt once with wordpress/phpBB, I have vowed to never do it again. In an attempt to eat-my-own-dog-food, I decided to do this all from scratch with s2 and friends. So, I'm creating a site that is centered around managing a team. The goal is to make a resource for parents and fans to discuss the teams and athletes. It will mostly be a knock-off of other blogs and forums, but it will provide some extra functionality for whichever sport is being managed. So, stats, pictures and videos can be uploaded. A schedule can be viewed (and managed by coaches). Coaches can blog about the various events (matches, tournaments, etc.). And, users can post in a forum (polls, regular forums). The fun part - The site is struts 2.1.?-SNAPSHOT based using Maven, Spring, Hibernate (JPA), SiteMesh, Acegi, and Prototype/JQuery (haven't decided yet). I'm using the codebehind plugin and other than acegi, I've hardly written any configuration at all! It's wonderful. The breakthrough I had was that I've created something like 40 entities so far and just began work on s2 actions. I was crossing my fingers that my generic dao, codebehind and spring autowire would allow me to code by convention and that things would work properly. Imagine my surprise when I had my first action working in less than a few hours! When I'm done, I may yank the guts out and post an integrated blog/forum project to sourceforge as an example of s2/spring/sitemesh/jpa with hints of AJAX, but that's a ways out... -Wes - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Fans are the best coach. Did you know that!? As I understand your project I it sounds close to what certain 'low-level' European soccer clubs are doing to raise money for their club. For a little fee every fan owns part of the club and over the web they can decide over the formation, the training schedule and what else. In some case the coach has to do what the people say in other case he simply has to justify if not doing so.

Re: Dojo not working in Struts2.
Hi Sharath, I am not quit sure, but I think it might help if you simply remove the s:head / tag. You see dojo is already configured inside of struts (inside the core jar and static folder or so) to be used with it's tags http://struts.apache.org/2.x/docs/tag-reference.html . Since you are not using any of those you can just remove the s:head /. This is what the head template looks like: http://struts.apache.org/2.x/docs/ajax-head-template.html You should thought consider using the struts2 tags. If you plan not to do so or you want to use a newer version of dojo since struts is a little behind you need to configure your web.xml file, as I believe, to use the static filter right to point to the location of your ajax files: filter filter-namestaticFilter/filter-name filter-classcom.bitpitch.webapp.filter.StaticFilter/filter-class init-param param-nameincludes/param-name param-value/scripts/dojo/*,/dwr/*/param-value /init-param /filter regards sharath karnati schrieb: Hi All, Please find 'test4Dialog.jsp' in attachment.

That will only work if the value you're trying to pass is a string.
It might also add whitespace to either end of that value (due to the
whitespace inside your s:set tag.
Why not pass the OGNL expression to your tag as a string and evaluate
it inside your custom tag, instead? If you use this custom tag in
many places, I predict the extra jsp required to pre-evaluate the
OGNL-string will be error-prone...

I must add that s:set printed out the string as well. I am not quit sure
if its supposed to, but it did. Therefor I even had to encapsulate
s:property with a s:param statement. Like this
s:iterator value=model.list
s:set name=value
s:param name=value
s:property value=top/
/s:param
/s:set
custom:tag attr=${value} /
/s:iterator
This is quite a big block for little I wanted to achieve.
I thought about passing the whole list to the tag too, but somehow it
did not feel like the right thing to do, at least as I would have done
it. My understanding of struts is not as experienced so if I may ask,
why would I need an extra jsp to pre-evaluate the OGNL as string as you
proposed?

I glossed over this--I wouldn't use s:set here, but rather c:set.
Neither one should print the value (are you sure you didn't do that
for debugging inside your custom tag?), but since you're trying to set
a value to be extracted with EL, I'd use the tag library that is
geared toward EL.
That would be:
c:set var=stringArgForCustomTags:property //c:set
custom:tag attr=${stringArgForCustomTag}/
My understanding of struts is not as experienced so if I may ask,
why would I need an extra jsp to pre-evaluate the OGNL as string as
you proposed?
You don't. If you want to use EL exclusively to extract the data,
don't use s:iterator, but rather one of the c: loop tags, then you
won't need the set. If you want to use OGNL to name/manipulate/etc.
the data, then something needs to be able to take that OGNL expression
and evaluate it. Your current solution to that is to have s:property
do the work, and have c:set store the results of that work in a place
that can then be handed off to your custom tag. An alternate solution
would be to enable your custom tag to evaluate OGNL directly. So
you'd probably have within your tag a String setter for attr that just
stores the string expression (argExpr below), then in your doTag (or
doStartTag, or whatever) do something like the following:
PageContext pageContext = (PageContext) getJspContext();
ValueStack valueStack = TagUtils.getStack(pageContext);
argValue = valueStack.findString(argExpr);
to ask OGNL to evaluate the expression for you and give you the
resulting value.
So, two different solutions, neither of which need the :set tag:
(the first assumes the collection is in some space where it can be
grabbed by EL, the second that your custom tag does it's own OGNL
evaluation)
c:foreach var=customTagArg
items=${some.el.expression.that.returns.the.collection}
custom:tag attr=${customTagArg}/
/c:foreach
or
s:iterator value=%{model.list}
custom:tag attr=%{top}/
/s:iterator
