Trivial Q

[Khan, Manuchehar A (ACF)]

This q is irrelevant to strusts but somebody can solve this easy puzzle that
I am stuck with
I have an multidimentional array rows*columnsCan someone figureout code
to get the x, y poisition in this multidimentional array if i know the
number

For example I have number 10.Its position in array for size (4X4) will
be 3rd row and 2nd column...
What will be the code to get number when size of array of number change
dynamically...

Thanks

Huge action instance synchronization problem

[Dan Bunea]

 
My problem: I have a search action. When 2 (or more) users submit the
search form simultaniously, because the seach usually takes about 1-2
seconds, the same action instance is rethrieved to complete the search
and sessions are combined like this: the action makes the search for the
first session but does not finish until the second search is performed
and because the resultset is divided into pages and this divisation is
stored into session, both pages with results are put in the second
session, and the second user shall be dispalyed the correct results but
the first shall have null pointer exception because in his session there
is no object representing the divisation of the resultset on pages. 
 
The problem in my opinion is because the same action instance performs
the same task for the 2 users and so the sessions are combined, which is
a huge problem, because like this every method of an action (dispatch
action) that takes a while to complete shall have the same problem.
 
Please advise me how to solve this problem. 
Thank you , 
Dan Bunea
 
PS Dear Craig , I am sorry to bother you but this problem is very
urgent, as the project is in final stages and this is a potentially huge
problem.
 I have read that each action is instantiated only once in the
RequestProcessor and for each request the action is rethrieved and its
methods executed, but I have also read that this is not synchronized.
 

Problem with validator arguments - message is beingsubstituted by 'null'

[Greg Tan]

I am having a problem with the validator.  It is not substituting the
message with the correct values, null is being substituted instead.  I
am using Struts 1.1b.

I have a custom validator which checks that a phone number has a
minimum number of digits (excluding special characters like spaces, plus
signs, minus signs etc.) so I can't use the standard minlength
validator.  There are mask and maxlength validation rules on the field
which are working perfectly.  My custom validator is working perfectly
(i.e. validating when it should and returning messages when it should),
it is just the error message that is not working.

Expected response when validation fails is:

Home Telephone Number must have at least 10 digits.

instead, I am getting 

Home Telephone Number must have at least null digits.

Does anyone have any clues about this??

Thanks...

Greg.

The action instance itself doesnt have any member variables does it?
If you store stuff in the HTTPSession each user will have their own session

RE: Huge action instance synchronization problem

[Dan Bunea]

I know it shouldn't have this problem. It is not the same session, nor
the same user that performs the search. Of course each user has the same
session, but let me explain some more of what I have seen happening.

The first user (say with session id #s1) obtains the action instance (
say instance #1) from the ActionServlet (RequestProcessr). The action
execute(..) starts executing, and makes the query into the database. At
this time the second request comes to the ActionServlet (say with
session id #s2), of course it has another session created for it,
obtains the same action instance as the the first user (#1), and because
the query in the database is not finished, the second user sets its
session into the action (#s2), so when the first query is finished I
call request.getSession()  it returns the second users session (#s2) for
both users, for the first that made the call and also for the second.
Now I have tried to make the execute () method synchronized but it did
not have any effect.

how can I do it? using validation without formset.

[Arik Levin ( Tikal )]

 
I want to use validation at struts 1.1b2, with no validation.xml descriptor.

 
Can anyone have an example for this one?

parameter in session

[Marcus Biel]

Hi,

I got an select box, where you can select a value. When you hit submit,
you get displayed a list of data records that fit to that value.
But the selected value should get stored for the whole session,
so if you hit on edit or delete that you directly get displayed the
table,
wihout selecting the value another time.


At the moment I got something like this:

html:form action=selectPlant.do method=POST
html:select property=plantSelection size=1
html:options collection=plantList property=mo/
/html:select br
html:submit/
/html:form
logic:present parameter=plantSelection
table
tr
tddata record/td
html:link page=/editGroup.do/html:linkEdit/td
/table
/logic:present
(The real page is much more complicated, but this should do it to
understand the problem faster)

So when I hit edit, I want to be able to edit the data record on the
same page. Therefore when backwarding to this page, 
the table directly needs to get shown, without to hit on the submit
button.

Got me ?


If you understan what I mean, help would be appreciated.

thanks in advance,

marcus

Re:[OT] Trivial Q

[David Derry]

This will work some of the time (maybe most). But you are missing edge
conditions. take 8 for ex. in a 4X4 that would be row 2 column 4. But your
foumula places it at row 3 column 0. However, right now I can't think of a
better solution (too early on a Mon morning!), other than to test for column
== 0, in which case --row; column = numberOfColumns.

Subject: parameter in session


 Hi,

 I got an select box, where you can select a value. When you hit submit,
 you get displayed a list of data records that fit to that value.
 But the selected value should get stored for the whole session,
 so if you hit on edit or delete that you directly get displayed the
 table,
 wihout selecting the value another time.


 At the moment I got something like this:

 html:form action=selectPlant.do method=POST
 html:select property=plantSelection size=1
 html:options collection=plantList property=mo/
 /html:select br
 html:submit/
 /html:form
 logic:present parameter=plantSelection
 table
 tr
 tddata record/td
 html:link page=/editGroup.do/html:linkEdit/td
 /table
 /logic:present
 (The real page is much more complicated, but this should do it to
 understand the problem faster)

 So when I hit edit, I want to be able to edit the data record on the
 same page. Therefore when backwarding to this page,
 the table directly needs to get shown, without to hit on the submit
 button.

 Got me ?


 If you understan what I mean, help would be appreciated.

 thanks in advance,

 marcus

Validation, javaScript modal windows

[Albuquerque, Ronald]

Hello,

I'm working on a project that has a lot of existing static HTML; this will serve as the
basis for the JSP's for the J2EE application.

I've come across a situation in the HTML and I'd like to please ask your help.

Existing Flow (in static HTML pages):
1. End-User sees information page on a particular account. There is also a Change link.
2. If user clicks this Change link, javascript is called that brings up another HTML
file (change account page) in a browser modal window. The user can edit 
information on the account, and then click 'Save' or 'Cancel'.

I have converted this to Struts and JSP's. 
1. Information page and change account page, converted to JSP's. use a form bean.
2. The existing javaScript is still called to pop up the modal window displaying the 
change account page.

I want to use the Struts Validator on the change account page. When the user
clicks Save, it should send a request to the server. The form bean extends 
ValidatorForm. So  - the validation will either be successful or not.
   
If not successful:  user will be returned to the same modal popup window, with 
validation errors displayed. If successful, popup window disappears, account 
info page is updated.

The problem I'm seeing right now is in the case where the validation is unsuccessful.
Using server-side validation techniques, how can I get Struts to return to the 
javascript modal popup window ?

(Only way I can do so right now is by turning on client-side validation, so if the 
user 
can submit successfully, then it implies all validation has passed).

Your help is really appreciated.

Thanks so much.

Regards,
Ronald Albuquerque.

RE: html:option with iterate

[Sri Sankaran]

It is much easier if you use the 'collection' attribute of the html:options tag.  
See http://jakarta.apache.org/struts/userGuide/struts-html.html#options.  Also take a 
look at the html-select.jsp file that is in the struts-exercise-taglib application 
that ships with Struts.

It is good practice to have a delegate class that handles all business
logic.  This will not only ensure that you don't run into problems such
as you state but also de-couples your business logic from the Struts
framework -- which *should* be used only for controlling your
presentation.

public class SomeAction extends Action {
  public void execute(...) {
Delegate delegate = new Delegate(...);
delegate.execute(...);
  }
}

The delegate is responsible for all business operations including (any)
database calls.
Also make sure that your action class doesn't have any instance

should have all the information that would be needed.  This way sessions

and sessions are combined like this: the action makes the search for the

and because the resultset is divided into pages and this divisation is
stored into session, both pages with results are put in the second

the first shall have null pointer exception because in his session there
is no object representing the divisation of the resultset on pages. 
 
The problem in my opinion is because the same action instance performs

a huge problem, because like this every method of an action (dispatch

RE: Huge action instance synchronization problem

[Sri Sankaran]

As I pointed out, it de-couples your business logic and the data from how it is 
presented to the user.  Further, it promotes re-usability.

You have found your problem to disappear when you mark the execute() method as being 
syncrhonized.  Is this a tenable alternative?  Won't it affect the scalability of your 
application?

As you've probably seen, 
http://jakarta.apache.org/struts/userGuide/building_controller.html#action_classes is 
a good read.

RE: [JSTL] c:out and DynaBeanClass

[Parmar, Dipakkumar]

sometimes I need to display field value from my DynaValidatorForm based on
user role and some criteria.

For example
c:choose
c:when test=${user.Admin}
html:text property=budget /
/c:when
c:otherwise
bean:write name=MyDynaValidatorForm property=budget /
/c:otherwise

and sometimes
bean:write name=MyDynaValidatorForm property=accountName /
bean:write name=MyDynaValidatorForm property=budgetSpend /

Let me know if you have any workaround, right now I'm using normal bean
write tag. I have converted all struts tag to struts-EL tag (except
bean:write) and so far I don't have any problem.

My JSP files look so clean now.

Yes, the struts-example (from the distribution) takes advantage of i18n.

Change (or add) browsers settings to use Russian [ru] or Japanese [ja], make
sure the order of precedence is first for one of those.  And hit your
running app. (you might need to restart tomcat to kill the session if you've
already hit the app using the default locale).

Should work fine from there.

Re: Serialization question...

[Eddie Bush]

Does the form contain any fields which do not implement Serializable? 
If so that makes the form unable to be serialized.  In order for an 
object to be serializble both that object and *all* fields it contains 
*must* implement Serializable.  It cascades too, so the fields' fields 
(if they are not simple types) must implement Serializable - and so 
forth.  Is this your problem, perhaps?

has to offer.  I have yet to meet anything that comes close to what this
framework can do.


Maybe this should be in it's own thread but I would be interested in 
advantages that other frameworks may offer. I hate seeing people get too 
much in the 'home team' mentality rather than the 'best tool for the 
job' mentality. I like struts and am in the middle of my 3rd project 
with it but I can't believe it's the best tool for every possible web 
publishing job.

Struts seems very focused on form handling and is perfect for web 
applications but what about a large brochure site? I would think another 
framework (like cocoon) might work better for a site that needs to 
manage 100s or 1000s of detailed pages but has little user input.I could 
see how tapestry or xmlc might work better where html designers are 
going to be working on the site more than programmers.

I'd like to see comments like Framework X is better than Struts where 
you have situations Y and Z.

RE: Huge action instance synchronization problem

[James Mitchell]

As Andrew pointed out, you are probably using a class level (member)
variable.

Can you move this to the execute method and retest?

Also, you should seriously consider what Sri has posted as well.

 Thank you, but what happens if I set the execute method from the action
 synchronized? I did that and it works fine. I have also run some tests
 to see if performance drops but it did not.

 It is good practice to have a delegate class that handles all business
 logic.  This will not only ensure that you don't run into problems such
 as you state but also de-couples your business logic from the Struts
 framework -- which *should* be used only for controlling your
 presentation.

 public class SomeAction extends Action {
   public void execute(...) {
 Delegate delegate = new Delegate(...);
 delegate.execute(...);
   }
 }

 The delegate is responsible for all business operations including (any)
 database calls.
 Also make sure that your action class doesn't have any instance
 variables and only stack-resident method scope variables.  The delegate
 should have all the information that would be needed.  This way sessions
 don't step on each other.

 Subject: Huge action instance synchronization problem



 My problem: I have a search action. When 2 (or more) users submit the
 search form simultaniously, because the seach usually takes about 1-2
 seconds, the same action instance is rethrieved to complete the search
 and sessions are combined like this: the action makes the search for the
 first session but does not finish until the second search is performed
 and because the resultset is divided into pages and this divisation is
 stored into session, both pages with results are put in the second
 session, and the second user shall be dispalyed the correct results but
 the first shall have null pointer exception because in his session there
 is no object representing the divisation of the resultset on pages.

 The problem in my opinion is because the same action instance performs
 the same task for the 2 users and so the sessions are combined, which is
 a huge problem, because like this every method of an action (dispatch
 action) that takes a while to complete shall have the same problem.

 Please advise me how to solve this problem.
 Thank you ,
 Dan Bunea

 PS Dear Craig , I am sorry to bother you but this problem is very
 urgent, as the project is in final stages and this is a potentially huge
 problem.  I have read that each action is instantiated only once in the
 RequestProcessor and for each request the action is rethrieved and its
 methods executed, but I have also read that this is not synchronized.

[Tiles] Using Tiles Parameter in logic:equals

[Jerry Jalenak]

I'm trying to find a way to pass a parameter from a tiles definition into a
JSP so I can use logic:equal to check the parameter and then render the
appropriate 'chunk' of JSP.  I can pass the parameter from my base
definition to my tile by using tiles:put; when I use tiles:get to
retrieve it I don't seem to be able to use it in my logic:equal tag to
check it against a static value.  Am I missing something obvious?  Is there
a more appropriate way of doing this?

is there a way to use Oracle JDBC Datasource

[Petit, Yannick (FR, Ext:Oxymel)]

Hi,

I'm new to struts, and looking for it to decide use it or not for our new
Dev in J2ee MVC² Project.
Our most imprtant requirement is to interact with Oracle (8i) Database so
for powerfull Apps ( Large Corporate Intranet) we planned to use the Oracle
JDBC Datasource and most particularly the OracleConnectionPoolDatasource I
look in the code and all of the two ( OracleDatasource 
OracleConnectionPoolDatasource )implements javax.sql.Datasources but when I
defined my datasource in struts-config.xml :

data-sources
data-source key=poolOracle
type=oracle.jdbc.pool.OracleConnectionPoolDataSource
set-property property=autoCommit value=false /
set-property property=driver
value=oracle.jdbc.driver.OracleDriver /
set-property property=user value= /
set-property property=password value=xxx /
set-property property=url
value=jdbc:oracle:thin:XXX:1521:XXX /
set-property property=description value=Prest_DSI /
set-property property=readOnly value=false /
set-property property=inactivity-timeout value=30 /
set-property property=maxCount value=10 /
set-property property=minCount value=2/
/data-source
/data-sources

And Still get the same message when I running it in my web server:

RE: how can I do it? using validation without formset.

[Arik Levin ( Tikal )]

Because my fields are coming from the DB and I don't know the field's names,
yet.
I'm using struts syntax for example html:text property=value(fieldname)/

So in that way I can't use the descriptor (validation.xml). 
How can I do it thru the API? Or is there any other suggestions?

RE: nested:iterate recursion inverts tree

[Steve Hall]

Arron,

Weblogic 5.1 sp11 is running JSP spec 1.1.  It sounds like that is
the root of my problem.  I'll just 'manually' nest my jsp until we get
upgraded to Weblogic 7.  Then I'll come back and implement the recursion.  

Thanks for your time!

So you ran the directory tree war (the end of the monkey-tree example),
and the directory tree came out upside down?...

If it did, I'd have to say it's how your container is evaluating the
JSP. I would think that it's compiling all the objects and evaluating
their output. But in doing so, it's committing their content to the
response stream in the wrong order.

The directory tutorial's been tried in many containers and comes out
sweet. What JSP spec version is that version of WebLogic?... It's
probably amazing that it can compile the true recursion at all. Most
containers have to be on the later JSP spec.


Arron.

 -
 nested.jsp
 ...
 nested:root
   nested:iterate property=nodes
 nested:write property=nodeName/br
  jsp:include page=nested.jsp /
   /nested:iterate
 /nested:root

 I would expect the page to display:
 
 root
   node1
 node1.1
 node1.2
   node2
node2.1
  node2.1.1
 etc...
 
 The monkey tree tutorial and my experimentation displays the tree as:
 
  node2.1.1
node2.1
   node2
 node1.2
 node1.1
   node1
 root
 
 Is this the expected behavior of the nested iterate tag when recursively
 displaying a Composite (tree)?  Am I using the tags incorrectly?  How do I
 get the JSP to display the tree root down?  Is there something in my
 environment that is causing the JSP iteration to run before any printing
to
 the outputstream is executed?  Do I have to hard code all the iteration
 levels into my JSP to get the tree to display root down?

 Struts 1.1 b2
 Weblogic 5.1 sp11 (don't ask :-/ )

Checkbox column and paging.

[Susan Bradeen]

I have a JSP table that contains a checkbox column used for multiple 
selection, which returns the selected item(s) Id value to a String array 
in my ActionForm bean. Happily, this is working. However, my problem is 
with paging. I am using the Display Tags to display my table, with a 
Decorator to show my checkbox in each row. The selected Id values that 
pass to my form bean are only the values on the current page of my 
table. Other items I have selected in the previous and next pages are 
not remembered and passed to the form bean array field. 

I need a little help following through with this, could someone please 
point me in the right direction? Is there a way to collect all the values 
on each page before submitting the form, so that all of the selected 
values are saved in the array? Will this require some sort of custom 
manipulation (not experienced with this) of the paging tags? 

Thank you,
Susan Bradeen

Re: Serialization question...

[David Graham]

You can use the transient keyword in a class to mark un-serializable members 
so that the rest of the class is serializable.  For example, if your class 
had a variable

private Connection conn;

your class would not be serializable because the sql Connection class isn't. 
 So you do this:

private transient Connection conn;

This is a little off topic, but does anyone know how I can get my hands on
an older version of JAXP?  We had to rebuild a server, and the newer JAXP
1.2 does not work with our existing Java code.  I got my hands on a older
version of crimson.jar, but I need the older versions of jaxp.jar and
xalan.jar.  We need to get up and running now, we can't afford the time to
rewrite our older Java code to work with 1.2.  I can't find it on the Sun
site, nor by doing a search under google.com.  Anyone have any suggestions
as to where I can get my hands on JAXP 1.1?

Thanks for your edification, Mr. Graham ;-)  I'd never had call to use 
that one before.

You can use the transient keyword in a class to mark un-serializable

your class would not be serializable because the sql Connection class

private transient Connection conn;

Hi,

My Struts 1.1b1 application must be deployed on a Websphere Application

I know there is a problem with the XML parser: WAS use a parser compatible
to JAXP 1.0 whereas
Struts 1.1b1 use a parser compatible to JAXP 1.1.

The problem is that my client doesn't allow me to change the admin.config

upgrade the xml parser of WAS.

Is there any other solutions to make work Struts with a xml parser

Re: Struts 1.0.2, Tomcat 4.1.12 Web-App start-up funny

[David Graham]

I suggest you develop with tomcat 4.1.12 since you're deploying on that 
version.  It will make your life easier with less surprises.  You should 
check what object is stored under org.apache.struts.taglib.html.BEAN in the 
request.  It may not be the bean you think it is.

Subject: Struts 1.0.2, Tomcat 4.1.12 Web-App start-up funny
Date: Mon, 28 Oct 2002 17:23:21 -


A plea for help to the great Struts User community.

I'm in the process of deploying our first Struts-enabled Web-App onto a
separate Staging Server. This is running Win 2K SP3, JDK 1.4.1  Tomcat
4.1.12.

Everything works fine when I first deploy my WAR file and start Tomcat. It
is unpacked correctly and the Web-App runs fine. If I stop and re-start
Tomcat I get the following error message when I attempt to access an Admin
Page using an HTML form with an associated Struts Form Bean :-

javax.servlet.jsp.JspException: No getter method available for property
archiveServer for bean under name org.apache.struts.taglib.html.BEAN
	at
org.apache.struts.taglib.html.SelectTag.doStartTag(SelectTag.java:304)
	at
org.apache.jsp.ResultArchiveAdmin_jsp._jspService(ResultArchiveAdmin_jsp.jav
a:265)

The relevant part of my Struts-config.xml is :-

  form-beans
form-bean  name=ResultArchiveAdminFormBean

type=com.anritsu.eu.Expresso.Beans.ResultArchiveAdminFormBean/
  /form-beans

...

!-- Add Result Archive --
actionpath=/AddArchive
   type=com.anritsu.eu.Expresso.ActAddResultArchive
   name=ResultArchiveAdminFormBean
  scope=request
   validate=true
  input=/ResultArchiveAdmin.jsp
  forward name=success path=/ResultArchiveAdmin.jsp/
/action

I think that this exception is telling me that the Struts TagLib could not
find a matching getArchiveServer() method in the Form Bean. But why did 
it
work the first time I ran up Tomcat? I have checked that the Bean does have
a matching method. Is it significant that the exception does not mention 
the
ResultArchiveAdminFormBean by name?

This is a bit frustrating as the same WAR file runs fine on my development
machine, but this is using JBuilder 6  Tomcat 4.0.1. I would prefer to use
a later version of Tomcat for deployment.

Obviously I must have missed something out from either the
Struts-config.xml, web.xml or in the JSP for this page. As this happens the
first time I attempt to access this page could it be a problem with an
instance of the FormBean being created? I've not explicitly added a
jsp:useBean ... statement into the JSP page as I thought that Struts 
would
sort this all out for me. Do I need one?

Any ideas would be gratefully received.

Many thanks.

Neil.

Each application deployed on WAS has in its classpath the jar which contains

I can't add at the begining of this classpath the xml parser 1.1 to make the

Can validator mask rule be made optional

[Halvorson, Loren]

Currently we are using the validator-rules.xml that comes with the Struts
1.1 distribution.  We have several situations where we have fields we need
to conform to a pattern _if_ the user enters data, but the fields are not
required (ex: phone number, e-mail).  We noticed that the mask validation
rule and the email validation rule depend on required.  Is there an easy
way to accomplish making these optional (short of duplicating the entire
rule and making an optionalMask by removing the required
dependency...which is what we are doing now)

validator name=mask
  classname=org.apache.struts.validator.FieldChecks
  method=validateMask
  methodParams=java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionErrors,
javax.servlet.http.HttpServletRequest
  depends=required  ---REMOVE THIS REQUIRED
  msg=errors.invalid
  javascript.../javascript
/validator

A thought just occurred to me as I was typing this. I suppose we could
rewrite the regular expression to accept empty string _or_ a valid phone
pattern...duh.  I suppose this is the preferred way to accomplish this.
Here is the pattern we are using today:

form-validation
global
  constant
constant-namephone/constant-name
constant-value^\(?(\d{3})\)?[-| ]?(\d{3})[-|
]?(\d{4})$/constant-value
  /constant
/global
/form-validation

I may be able to get this to work for the mask rule, but it doesn't solve
the email rule which doesn't use an exernally specified regular expression.
Does anyone else have a form with an optional e-mail?

Thanks

Re: Huge action instance synchronization problem

[Craig R. McClanahan]

As others have pointed out, 99.9% of this kind of a problem comes from
using class-level instance variables (also called member variables) to
store information that is specific to a particular request.  This fails
because there is only one instance of the Action, so the instance
variables are shared across multiple requests.

Actions must be designed in a thread-safe manner.  In particular, you
should never use instance variables in an Action class, unless you
SPECIFICALLY intend to share that variable across multiple users.

Variables local to the perform() or execute() method are not shared, so
that is where you should store things specific to a particular request.

 Subject: Huge action instance synchronization problem


 My problem: I have a search action. When 2 (or more) users submit the
 search form simultaniously, because the seach usually takes about 1-2
 seconds, the same action instance is rethrieved to complete the search
 and sessions are combined like this: the action makes the search for the
 first session but does not finish until the second search is performed
 and because the resultset is divided into pages and this divisation is
 stored into session, both pages with results are put in the second
 session, and the second user shall be dispalyed the correct results but
 the first shall have null pointer exception because in his session there
 is no object representing the divisation of the resultset on pages.

 The problem in my opinion is because the same action instance performs
 the same task for the 2 users and so the sessions are combined, which is
 a huge problem, because like this every method of an action (dispatch
 action) that takes a while to complete shall have the same problem.

 Please advise me how to solve this problem.
 Thank you ,
 Dan Bunea

 PS Dear Craig , I am sorry to bother you but this problem is very
 urgent, as the project is in final stages and this is a potentially huge
 problem.
  I have read that each action is instantiated only once in the
 RequestProcessor and for each request the action is rethrieved and its
 methods executed, but I have also read that this is not synchronized.

RE: how can I do it? using validation without formset.

[James Mitchell]

If you do not know what the field names are before displaying the page, how
could you possibly validate them?

Are you storing the validation in the database as well?
If so, it sounds like you need to develop your own custom validation.

Sorry I can't help you further.  FWIWgood luck.

If anyone is interested, I figured this out.  Of course this is a basic
JavaScript problem so I understand not getting a response on the Struts
list.  Never the less, I feel that it pertains enough for a solution to be
submitted.  

onSubmit is not called if you use JavaScript to submit a form.  Rather, you
must call it yourself.  So an html:link that submits a form, and used the
Struts Validator client side JavaScript might look like:

html:link href=# onclick=javascript:if
(document.forms[0].onsubmit())document.forms[0].submit()
Submit bean:write name=project property=title /

the history in the html:password?

RE: Submit Using html:link and html:javascript

[Madel,Kurt]

Yes, I suppose so but the powers beyond me like the way they look.  On the
plus side, you can then use a link for cancel that href's an action.

Also, this would work well if you wanted to use an image for submit
purposes.

If anyone is interested, I figured this out.  Of course this is a basic
JavaScript problem so I understand not getting a response on the Struts
list.  Never the less, I feel that it pertains enough for a solution to be
submitted.

onSubmit is not called if you use JavaScript to submit a form.  Rather, you
must call it yourself.  So an html:link that submits a form, and used the
Struts Validator client side JavaScript might look like:

html:link href=# onclick=javascript:if
(document.forms[0].onsubmit())document.forms[0].submit()
   Submit bean:write name=project property=title /
/html:link

form and action in struts-config

[Vankineni, Naga X]

Can anyone explain me why I get this problem...
I have my action and form defined in the struts-config.xml..
Now in my jsp page when I enter a value in the text-box and try to see the
value in my action using debugger, I don't see that value in my form and all
i see is the reset value defined in the form bean.
Somehow anyvalues I enter in my jsp pages aren't getting moved to the form
and they my form just has the reset values defined initally.
Can someone explain this to me..

RE: Submit Using html:link and html:javascript

[Wendy Smoak]

 Is there a struts tags for an input image?

Assuming you mean a SUBMIT button with an image on it instead of text,
here's what I'm using:

html-el:submit property=submit  onclick=setAction('Add Prospect');
styleClass=addButton titleKey=button.add.prospect value= /

And here's the style that goes with it:

.addButton {
background-image:url(images/add.gif);
background-position:center;
background-repeat:no-repeat;
background-color:lt grey
}

The setAction javascript is necessary because you can't have a value
without the text appearing on the button.  (Or, I couldn't figure out how.)
So I put a value into the hidden 'action' form field and then use that in a
LookupDispatchAction:

function setAction(target) {document.forms[0].action.value=target;}

It took a long time to piece all this together.  Hope it helps someone else!

Struts Validator for multiple Selects

[Madel,Kurt]

We have a multiple select that is required. The following works on server
side, but not client side:

form name=milestoneDetailForm
field 
property=mspersonsIds[0]
depends=required
arg0 key=label.milestone.mspersonsIds/ 
/field 
/form

If changed to the following, it is caught on the server side, but no message
is printed:
form name=milestoneDetailForm
field 
property=mspersonsIds
depends=required
arg0 key=label.milestone.mspersonsIds/ 
/field 
/form

Any ideas? Thanks

RE: Problem with multiple html(jsp) pages sharing one form (actionform)

[James Mitchell]

Hi Derek,

Sorry for not getting back sooner.


 if you are using the same action and jsp for your wizards, how
 are they qualified to be wizards?

Whenever I need a wizard-like flow in my application, I use a single action
and a single jsp to go from Step 1 to Step n.

I can do this by passing around a token called step, which is a field on
my form used only for the purpose of this wizard.


Here's a bit of psuedo code...

wizard.jsp
--
taglib declarations

html:form blah blah
!-- Stuff you want on every page --


!-- Step 1 --
 logic:equal name=wizardForm
  property=step
  value=1

  Field 1:html:text property=field1/br
  Field 2:html:text property=field2/br
  Field 3:html:text property=field3/br
  Field 4:html:text property=field4/br
  Field 5:html:text property=field5/br

 /logic:equal

!-- Step 2 --
 logic:equal name=wizardForm
  property=step
  value=2

  Field 6:html:text property=field6/br
  Field 7:html:text property=field7/br
  Field 8:html:text property=field8/br
  Field 9:html:text property=field9/br
  Field 10:html:text property=field10/br

 /logic:equal

!-- Step 3 --
 logic:equal name=wizardForm
  property=step

So I handle the form submit and validation within my Action class (This give
me the most control).

By doing it this way, if I need to move field 6 thru 8 to Step 1, I can drag
it up
there within my text editor. (as opposed to cutting it from one jsp and
pasting into another)

Not to mention repeating the page headers footer and any other page data
(style, javascript, etc)

 (actionform)


 James,
 First of all, if you are using the same action and jsp for your
 wizards, how
 are they qualified to be wizards?  Perhaps I am not getting what you mean.
 But a wizard would mean many different jsp's to me.  But anyway,
 that is not
 very important at this point.

 I tried what you have suggested.  All the data is gone.

 On top of that, I have did some debugging.

 This is what I get from the my RegistrationForm after I hit
 submit in step1:
 (As you can see the properties are set nicely)
 DynaActionForm[dynaClass=RegistrationForm,userPhoneType=,companyPa
 ssword2=,c
 ompanyEmailType=primary,companyPassword=,companyUsername=,creditca
 rdNumber=,
 companyPhone=1234567890,userEmailType=,companyName=u,companyZip=94
 112,credit
 cardType=,userPhone=,creditcardExpDate=,userRole=admin,companyFax=
 u,companyS
 treet=u,[EMAIL PROTECTED],firstName=,companyCountry=US,company
 State=u,us
 erFax=,companyStreet2=u,userEmail=,companyAddressType=primary,comp
 anyProvinc
 e=,companyPhoneType=primary,companyCity=u,lastName=]

 Now, when I hit submit on step2, here is what I get: (The previous values
 are gone.  Only new values are there.  The reset method had to be
 called or
 a new instance of RegistrationForm was generated.)
 DynaActionForm[dynaClass=RegistrationForm,userPhoneType=,companyPa
 ssword2=12
 3456,companyEmailType=primary,companyPassword=123456,companyUserna
 me=uyy,cre
 ditcardNumber=,companyPhone=,userEmailType=,companyName=,companyZi
 p=,creditc
 ardType=,userPhone=u,creditcardExpDate=,userRole=admin,companyFax=
 ,companySt
 reet=,companyEmail=,firstName=u,companyCountry=,companyState=,user
 Fax=u,comp
 anyStreet2=,userEmail=u,companyAddressType=primary,companyProvince
 =,companyP
 honeType=primary,companyCity=,lastName=u]

 One more thing is that, not sure if this is relevant, I am also using the
 struts validator to validate for form.  And while I fix the JavaScript to
 only validate the existing formfileds, the struts validator (java) is
 throwing exceptions on my console (since the form values don't
 exist -- I
 only use a portion of the form here -- you get the picture, right?)  These
 exceptions do cause the application to stop.  My app goes on with no
 apparent problems.  (At some point, I want to modify the
 validator to detect
 existing formfields only.  Or is anyone working on that?)

 To sum this up.  I think either the reset method is called or a
 new instance
 of my form is created.

 Do you have a example of a wizard working?--one that expands to
 two or more
 jsp's.  If so, can you just copy and paste the code

Token

[Ricardo de Souza Moura]

When I need to control transactions, I am using Tokens. I call saveToken() 
in the Action that forward to a page A.

my page A:

html:form action=/teste.do 
 input type=hidden name=method value=methodA/
 input type=submit/
/html:form

My Action teste.do is a DispatchAction, so my methodA will run!!!
I call:
 if (isTokenValid(request, true)) {...}

All run fine !!!

My Question:

The first thing that I said was that my Action call saveToken() and go to 
the page A...
But my Action only need to do this:
...
String forward = popupPromoMasterCard;
saveToken(request);
return mapping.findForward(forward);
...
I would like to know if there are another way to save tokens, for example 
with taglib !!!
So I could to use org.apache.struts.actions.ForwardAction...

Thanks !!!

RE: [Nested Tags] Nested vs logic tags..

[Jeff_Mychasiw]

No I have not.
I could be wrong but I am under the assumptiion that  the name attribute is
used to look for a bean.

The documents state that the nested versions of the tags will work the same
but allow you exclude specific references to parent tags.
I have done this many times:
  logic:iterate name=myFormBean property=meshList id=myObject
indexId=listIndex type=com.nlg.ar.SomeVo
logic:equal name=listIndex value=0XXX/logic:iterate
bean:write name=myObject property=legalName /
  /logic:iterate

  I like the nested version..
  nested:iterate property=meshList indexId=listIndex 
nested:equal name=listIndex value=0XXX/nested:iterate
nested:write property=legalName /
  /nested:iterate

  It is not the end of the world, but I in order to use the indexId I have
 to use the logic:equal
  (note the equal tag)
  nested:iterate property=meshList indexId=listIndex 
logic:equal name=listIndex value=0XXX/logic:iterate
nested:write property=legalName /
  /nested:iterate

does javascript have a place in mvc struts

Sorry this might be an elementary question, but im new to jsp and struts.
I have done a lot of reading in the last few weeks. I realize that struts
is the way to go in terms of following the mvc model. My one question at
this time is in regards to form validation. By that i mean when a user
enters information; lets say username  password should the information be
validated with the aid of javascript on the client side or is the concesus
to leave such a task to beans on the server side???

RE: action mapping input

[Chen, Gin]

Okay, I misunderstood what John was saying and this is what I have:
1) forward failure is NOT the same as input which is required if
validate=true
2) input CAN forward to a tiles definition.
I looked at the original post and realized that it was pretty ambiguous.
what i wanted to do (and it was successful)
was:

  action path=/siteSelect type=SiteSelectAction
name=siteSelectForm validate=true scope=request
input=site.select.page
 forward name=success path=site.select.global/
  /action

where site.select.page was a tiles definition.

Okay, just to get this straight.
So I define a failure forward and it will behave the same as validation
error following the input tag?
No additional coding required?
Also, the reason that I wanted to use the input tag instead of another
forward is that I want to use the 1.1b2 method getInputForward(). It would
almost make sense that with the inclusion of this new method, the intent was
for it to behave as if it were looking up a forward or global.
No?

Rather than have input=/logon.jsp as in the snip can you have
 input=logon and have it use the path from the global-forwards?
It just seems like it would make more sense since that means that you
 only have to change one location in case the location of the file ever has
 to change.
 


The input attribute is used when validation of the form bean fails. if 
the validation in the form bean (or the validator) fails the action is 
never run so it couldn't use the forward. The controller is returning 
you to the input page.

If a validation in the action fails (like a business logic failure)then 
you can use a failure forward.

I believe that there is not exactly a consensus. However, the Struts
Validator makes it easy to incorporate both.  Additionally, many will check
the data again in the model layer before it is persisted (i.e. inserted into
a database).

On the model layer, I use O/R mapping that helps with data integrity in the

Using tiles and container managed security/form based login

[Alan P Sexton]

[I have moved this branch of this thread to struts-users as it no longer
belongs on struts-dev; was: RE: [SURVEY] HREF attribute for FormTag] 

Thanks,

I should be able to use that advice to fix my problem. However I
still don't understand why my approach doesn't work:

I have CMS set up on /*. I put all my jsps under WEB-INF as per various
FAQ advice. Tomcat needs an accessible logon.jsp so that stays outside
(/logon.jsp). However, that just contains a logic:forward to a global
forward to /WEB-INF/jsp/logon.jsp which contains the appropriate
j_security_check form (in plain html). This works fine (although
thinking about it, it is not good as it is a jsp forwarding to a jsp -
even if it is the only one in my setup).

I then tried replacing the /logon.jsp forward to /WEB-INF/jsp/logon.jsp
to a forward to my new logon tile tile.cmsLogon. This does not
work. However I am sure that the setup of this tile is correct (famous
last words). I suspect it is something to do with how tile definitions
are spliced into the forwards' namespace but have not had time to figure
out enough of the Struts sources to be sure.

I hadn't thought of forwarding to a proper action instead which could
forward to a tile.

Many thanks

Alan

RE: does javascript have a place in mvc struts

[Joe Barefoot]

Not an elementary question at all, and the answer is:  It depends on the situation. ;)

First, your business requirements dictate where validation is possible.  If you are 
creating a service-type web application accessible via the Internet to many different 
kinds of users, then your business requirements may dictate that you must accomodate 
users who have JavaScript disabled.  This means that you must always validate 
server-side even if you have shortcut validation client-side w/ JavaScript, which 
will be used *if* JS is enabled.  

Even if it is specified that JavaScript is required for the application, you must 
ensure that no illegal data slips through by doing server-side data checks, if 
necessary.

Second, the general notion is that 'simple' validation like password-length/format, 
zip code length, phone number length/formats, etc., are best validated client-side 
with JavaScript.  Anything that requires complex logic, business rule evaluation, or 
database access should be validated server-side.  You should by no means transmit any 
sensitive information over HTTP for client-side validation, of course.  What you 
really are trying to do is limit the number of requests your server has to process by 
using JavaScript to validate the easy stuff.

One good rule-o'-thumb, I feel, is that if you have to transmit a lot of extra hidden 
information to do client-side validation with JS, then you should be doing it 
server-side instead.


peace,
Joe

RE: does javascript have a place in mvc struts

[Craig R. McClanahan]

You should absolutely, positively, perform validation on the server side
regardless of what you might do on the client side.  It is not appropriate
for a server-side application to trust the client (which might be anything
from a browser with JavaScript turned off to a malicious application
trying to corrupt your database).

That being said, performing validation on the client side as well is
useful, because it can improve the quality of the user experience and
reduce the turnaround time for errors.  However, there will be some things
that cannot be validated client side (compare is this the right number of
digits for a credit card number to is this a valid credit card number),
so you're going to need to plan on server side validation anyway.

Consensus or not, I'd say the answer is emphatically yes.  You 
certainly should not rely solely on javascript for validation, but 
javascript is a valid and useful part of the view layer, and as 
such, should be used for what it's good for, which is saving users 
the headache of waiting for a round-trip to the server to tell 'em 
they've messed up.

RE: [Nested Tags] Nested vs logic tags..

[Arron Bates]

 Just a hunch-- have you tried specifying a 'name' for the nested:iterate
 tag?  

The nested tags don't need it, and if it's provided they will ignore it.
Why?... because all the tags are working off the same bean structure,
and this is defined for us by the form tag. The nested tags will fetch
this bean. Because of this, all the nested tags within the form bean
don't need the name property to be set.


 From: [EMAIL PROTECTED] [mailto:Jeff_Mychasiw;nlgroup.ca]
 Greetings:
   I am almost exclusively using nested tags.
 Every now and then I run  into a problem and have to switch over the
 corresponding logic or bean version.
 
 Can anyony tell me if this is a bug?  I am using 1.1b2
 
 I tried this with nested:equal but got a NullPointerException (listed
 below)
 nested:iterate property=meshList indexId=listIndex
   tr
  td
  %-- Show this only for the first item--%
  nested:equal name=listIndex value=0
 
   /nested:equal

Try remove the name property (for reasons explained above), and try
aiming the property property at it.

It looks like you're trying to get the current object of the iterate
tag, so this may work...

nested:iterate property=meshList
  tr
td
  nested:equal property=this/ value=0
[...]
  /nested:equal
/td
  /tr
/nested:iterate


...the this/ or ./ simply refers to the current parent object level
just like using ./ on a command line. If it's not the current object
you're after, point the property at one of it's relative properties.

See if that works.


Arron.

Re: Using tiles and container managed security/form based login

[Alan P Sexton]

I am using logic:forward rather than jsp:forward. I had not checked it
but had assumed (perhaps naively) that since that is part of struts, it
would be tiles plugin aware. If it is not, then that would certainly
explain my symptoms and your suggestion will fix it.

Many thanks again.

Alan

  
  
   I then tried replacing the /logon.jsp forward to
   /WEB-INF/jsp/logon.jsp
   to a forward to my new logon tile tile.cmsLogon. This does not
   work. However I am sure that the setup of this tile is correct (famous
   last words). I suspect it is something to do with how tile definitions
   are spliced into the forwards' namespace but have not had
   time to figure
   out enough of the Struts sources to be sure.
  
  Are you using jsp:forward to forward from the logon.jsp? If so, that tag
  doesn't know how to handle tiles. You need to send the request through the
  controller servlet, with tiles properly setup. Then the tiles plug-in
  intercepts the forward and checks to see if it's really a tile.
  
  --from struts-config.xml
  action path=/login type=org.eei.rpwr.common.ui.LoginAction
   forward name=success path=nav.login redirect=false /
  /action
  
  --from tiles-definitions.xml
  definition name=nav.login extends=standard
  put name=body   value=nav.login.body /
  /definition
  definition name=nav.login.body path=/tiles/toplevel.jsp
  put name=content   value=/login.jsp /
  /definition
  
  
   I hadn't thought of forwarding to a proper action instead which could
   forward to a tile.
  
   Many thanks

error checking in Action

I need to do some extensive error checking, and need to move this into an action class.

my question is when i identify an action, how i forward back to the previous page (the 
same way a form class would).  is there a method to take care of this?  or do i need 
to setup all the passed values in the request again and do an ActionForward to the 
appropriate page?

Why do you need to move error checking into an action?  Why not just let

html:cancel problem

[Nicolas Parisé]

Hi,
 
I have problem with the html:cancel tag in STRUTS 1.02
 
 
I have an Action class that create an instance of a ActionForm, populate
it with data and put it in the session (session.setAttribute). Then my
action class redirect the request to a JSP page that display the data
from the session’s actionForm. The problem
occur when someone modify one of the fields in the JSP and then click
the cancel button. The data in the session has been modified event if
that’s a cancel button.
 
Is it normal?
 
 
 
Can someone help me with that?
 
 
Thank you!

Maxlength validation returns null in error message

[Jeff Born]

Hi all,
 
I've looking at the struts-example.war in 1.1b2 and when running through the
login.jsp page I keep getting the following username can not be greater than
null characters.  This happens via the JavaScript validation.  I thought
maybe it might be JavaScript related, but when I remove the onsubmit and let
the server validate I end up with the same message.
 
I think I found somewhere that this is an open error, but not sure where to
check.  Any direction here?
 
Is there a simple fix?
 
Is a fix in the works?
 
Thanks,

RE: error checking in Action

[Andrew Hill]

I do all my validation in the action too - I need a lot of info from the
b-tier about such things as which fields are mandatory when, etc... and it
proved inconvienient (still quite possible - just required some ugly
contortions - especially given some of the evil things Im doing in the
RequestProcessor which you would rather not know about ;- ) to do it in the
form. I rather like to keep my forms stupid too (ie: just a simple data
structure with getters and setters.) and put code that does the work of
validating, directing traffic, and calling the business objects together in
the same class. Not so OOPy, but I find it saves time and makes it easier to
locate and work on things.

In fact most of my crud actions are subclasses of a common abstract
(dispatch) action , which has an abstract validation method it calls and
then returns the user to the form complete with actionErrors as normal if
the validation fails. (Im cheating a bit , in that if my save method fails
due to validation errors, rather than doing a forward back to the input
(which is in fact that same action (Im not using JSPs but rather a homebaked
rendering technique based around DOM - which needs an action to set up the
renderers for the view)) I simply make a direct call to my update method...)

If you are validating in the action , you can get the relative path(*) to
return to if validation fails from mapping.getInput() which returns a
string - the contents of which are the value of the input attribute in your
action mapping in struts config. You could probably build an ActionFrward
out of this and return it from the action. Since you would be forwarding
(ie: make redirect=false) all the stuff in your request context will be
preserved and sent back to the input - including the ActionForm populated
from the request.

The code struts uses to call validation in your actionForm and return to the
input if it fails may (in 1.1) be found in the processValidate() method of
the RequestProcessor.



(*) Struts 1.1b2 appears to allow the input to be the name of a forward
instead of a path now, but I havent had time to examine this new
functionality yet.

Agreed,
For Generic type of validation the ActionForm is an appropiate
place to do validation. To restate what David said, the ActionForm
is designed to be passive, and have values info it needs passed
to it. It should definately not make method calls to other Business Logic.

To add to that,Any complex validation would take place in the Business

Subject: RE: Problem with multiple html(jsp) pages sharing one form
(actionform)


 Hi Derek,

 Sorry for not getting back sooner.


  if you are using the same action and jsp for your wizards, how
  are they qualified to be wizards?

 Whenever I need a wizard-like flow in my application, I use a single
action
 and a single jsp to go from Step 1 to Step n.

 I can do this by passing around a token called step, which is a field on
 my form used only for the purpose of this wizard.


 Here's a bit of psuedo code...

 wizard.jsp
 --
 taglib declarations

 html:form blah blah
 !-- Stuff you want on every page --


 !-- Step 1 --
  logic:equal name=wizardForm
   property=step
   value=1

   Field 1:html:text property=field1/br
   Field 2:html:text property=field2/br
   Field 3:html:text property=field3/br
   Field 4:html:text property=field4/br
   Field 5:html:text property=field5/br

  /logic:equal

 !-- Step 2 --
  logic:equal name=wizardForm
   property=step
   value=2

   Field 6:html:text property=field6/br
   Field 7:html:text property=field7/br
   Field 8:html:text property=field8/br
   Field 9:html:text property=field9/br
   Field 10:html:text property=field10/br

  /logic:equal

 !-- Step 3 --
  logic:equal name=wizardForm
   property=step
   value=3

   Field 11:html:text property=field11/br
   Field 12:html:text property=field12/br
   Field 13:html:text property=field13/br
   Field 14:html:text property=field14/br
   Field 15:html:text property=field15/br

  /logic:equal

 /html:form


 So I handle the form submit and validation within my Action class (This
give
 me the most control).

 By doing it this way, if I need to move field 6 thru 8 to Step 1, I can
drag
 it up
 there within my text editor. (as opposed to cutting it from one jsp and
 pasting into another)

 Not to mention repeating the page headers footer and any other page data
 (style, javascript, etc)

ExceptionHandler DispatchAction (1.1b1 vs b2)

[Andrew Hill]

Been trying to get my first struts ExceptionHandler to work today and just
came across another good reason to make the jump from 1.1b1 to 1.1b2.

Seems that exceptions thrown in a DispatchAction are handled correctly in
1.1b2 (ie: if possible thrown up where you can process them with an
exception handler) while 1.1b1 always writes an error response out
immediately using response.sendError() , thus preventing the exception
bubbling up to where the RequestProcessor can pass it to your
ExceptionHandler like it does for an Action.

Many cheers to the struts devs for fixing this! :-)

1.1b1 Code:
---
snip
} catch (InvocationTargetException e)
{
String message =
messages.getMessage(dispatch.error, mapping.getPath(),
name);
log.error(message, e);
response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR,
   message);
return (null);
}
/snip

1.1b2 Code:
---
snip
} catch (InvocationTargetException e) {
// Rethrow the target exception if possible so that the
// exception handling machinery can deal with it
Throwable t = e.getTargetException();
if (t instanceof Exception) {
throw ((Exception) t);
} else {
String message =
messages.getMessage(dispatch.error, mapping.getPath(),
name);
log.error(message, e);
response.sendError
(HttpServletResponse.SC_INTERNAL_SERVER_ERROR, message);
return (null);
}
/snip







btw
whinge subject=coding.style
I really can't stand this sun style java indenting thats used in the struts
source. Its so random and unreadable and ugly. Trying to scan more than a
few lines of it really gives me a headache. Id rather debug BF code (well ok
I wouldnt but at least BF doesnt pretend to be readable...)
When Im dictator for life everyone will have to use C style indenting and
put their curlies back where they belong...sigh/

  Sorry for not getting back sooner.
 
 
   if you are using the same action and jsp for your wizards, how
   are they qualified to be wizards?
 
  Whenever I need a wizard-like flow in my application, I use a single
 action
  and a single jsp to go from Step 1 to Step n.
 
  I can do this by passing around a token called step, which is
 a field on
  my form used only for the purpose of this wizard.
 
 
  Here's a bit of psuedo code...
 
  wizard.jsp
  --
  taglib declarations
 
  html:form blah blah
  !-- Stuff you want on every page --
 
 
  !-- Step 1 --
   logic:equal name=wizardForm
property=step
value=1
 
Field 1:html:text property=field1/br
Field 2:html:text property=field2/br
Field 3:html:text property=field3/br
Field 4:html:text property=field4/br
Field 5:html:text property=field5/br
 
   /logic:equal
 
  !-- Step 2 --
   logic:equal name=wizardForm
property=step
value=2
 
Field 6:html:text property=field6/br
Field 7:html:text property=field7/br
Field 8:html:text property=field8/br
Field 9:html:text property=field9/br
Field 10:html:text property=field10/br
 
   /logic:equal
 
  !-- Step 3 --
   logic:equal name=wizardForm
property=step
value=3
 
Field 11:html:text property=field11/br
Field 12:html:text property=field12/br
Field 13:html:text property=field13/br
Field 14:html:text property=field14/br
Field 15:html:text property=field15/br
 
   /logic:equal
 
  /html:form
 
 
  So I handle the form submit and validation within my Action class (This
 give
  me the most control).
 
  By doing it this way, if I need to move field 6 thru 8 to Step 1, I can
 drag
  it up
  there 

what for are nested tags ?

How to make the LazyList Serializable?

[William Wan]

I found the nested tag with LazyList is very useful for implementing
nested structure form submission. I would like to know is there any
simple method to make the LazyList Serializable so that I can store the
form object into session?
 
Thanks
William
