This is because when nothing is selected, nothing gets sent to the form to
be populated, so assuming your form is in session scope, whatever you had in
there when it was rendered, is still in there.  That's why inside the reset
method of the form you need to empty that string array.  That way if there
are value submitted they will be populated, and if there are none, it will
stay at none.

RE: Multibox problem when defaulted all on

[Wiebe de Jong]

I don't think I explained myself quite clearly. 

WORKS: All the checkboxes on the form default to on.
WORKS: User leaves all checkboxes on.
WORKS: User turns some of the checkboxes off.
DOESN'T WORK: User turns all of the checkboxes off.

In the last situation, the form reports to the action that the marketing
array still has the value of {"accountHolder", "user2", "user3", "user4",
"user5"}, even though the user turned all the checkboxes off.

If you keep your forms in session scope, this might be a problem if the
user "starts over" with this form at some point.  If there's already an
instance of the form in session scope, it will be reused, so the
constructor will not be called.  So if you're going to do this, you
might want to remove the form from the session when the user is
"finished" with it, whatever that means in this particular app.  Then if
they "start over" the framework will make a new form.

Re: Multibox problem when defaulted all on

[David Erickson]

I'm still a little hazy on when reset is called on forms, but you may want
to try moving
marketing = marketingItems;

to the forms constructor, so when the form is created the first time its
holding the default values.
And inside the reset method:

marketing = null;

RE: Multibox and selected values

[Craig Tataryn]

Oh right, sorry yeah my code looks in the Application scope in this instance.  

For getting the request scope variables I needed I had subclassed DispatchAction for 
my project and
set the properties on my form bean which were grabbed from the request from within an 
overriden
dispatchMethod (execute if subclassing normal Action) method.  I suppose you could do 
the same as
well and add a get/set UserSession property on your a subclassed ActionForm.  Not sure 
how great an
option that is?

Here's what my code looked like:

protected ActionForward dispatchMethod(
ActionMapping mappings,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response,
String methodToCall)
throws Exception {

if (form instanceof ApptiusForm) {
//here's where I grab some user session variables and present them to my form bean

((ApptiusForm)form).setSessionUserName((String)request.getSession().getAttribute(POActionServlet.USER_KEY));

((ApptiusForm)form).setSessionUserId((String)request.getSession().getAttribute(POActionServlet.USERID_KEY));
}

String dispatchTo = ApptiusUtils.isNull(methodToCall,"initialize");
ActionForward forward = null;

try {
forward = super.dispatchMethod(mappings, form, request, response, "do" 
+
ApptiusUtils.UCaseFirst(dispatchTo));
} catch (Exception e){
ApptiusLog.logError(e, this.getClass().getName() + "::" + "do" +
ApptiusUtils.UCaseFirst(methodToCall) + " does not exist, or an error occured within 
that function,
check stack trace below");
throw e;
}

if (forward == null) {
return mappings.findForward(dispatchTo);
} else {
return forward;
}
}

this.servlet.getServletContext().getAttribute() should give you access to beans in the 
user session.

RE: Multibox and selected values

[Saul Q Yuan]

Well the idea is rather than accessing this jsp page directly, try
accessing it through an action mapping, say /userInfo.do, so it goes
through an Action first before landing on the jsp page. In the Action
class, you can do all the data preparation work as discussed in previous
emails.

And then how do I get the session from there? I looked at the API and the 
servlet context object does not have access to the HttpSession object.

RE: Multibox and selected values

[Amish Patel]

How can I do what you are telling me do. Look at my code



 

   

  
How can I pass the user object to my associateUserRoleForm when there is no 
action invoked when the page is loaded.  Lets say that when the page is 
loaded an action is invoked, how do I get the associateUserRoleForm and make 
sure that when the taglib is invoked on my page that same instance of 
associateUserRoleForm is used.

Thanks in advance for your help!

Re: Multibox and selected values

[Amish Patel]

Saul,

How can I access the current user from the form bean?  The current user is 
in the session.  So in other words my question is how can I access the 
session from the form bean?

Thanks in advance for your help!

If I understand your questions correctly, you can define two String arrays 
in your form bean, one for allRoles, and the other for selectedRoles, which 
is the array of roles of the current user. Before forwarding to your jsp, 
in your action class, you can retrive all the roles of the currently user, 
and set the roles to the selectedRoles in the form bean.

Saul

  Hello All,

  I am running into this problem, that I am not able figure out how to do 
it
  properly.  I have searched the web and have not found a decent example.
  What I am trying to do is use html:multibox taglib to display a set of
  checkboxes.  These check boxes represent the user's security 
preferences.
  So if the user has a particular security token, then the respective 
check
  box should be checked.

  In order for this to work properly, I have to get two things, all the
  security tokens that exits in the system.  And I  have to get the 
security
  tokens that the user already has.  In my ActionForm, I have two methods:
  one that gets all the security tokens in the system and second that gets
  only the tokens that the user has.   The following is what I am using in 
my
  jsp to display checkboxes.

  

 



  
  Right now I am able to get allRoles successfully, but in order to 
retrieve
  the selectedRoles, I need a way such that my ActionForm
  (associateUserRoleForm) can get hold of this user or this user's id, 
which
  is already in the session.  Once I get this I can then display all the
  security tokens and check those tokens that the user already has.

  How can I do this?  Am I on the right track or is there a better way to 
do
  this?

  Thank You very much for your help!

can retrive all the roles of the currently user, and set the roles to the

RE: Multibox and Validation

I downloaded the nightly build from last night.  It did fix the
javascript validation but if I turn javascript off, the validators still
don't enforce the required validation on the multibox.  Any
suggestions?

>>> [EMAIL PROTECTED] 01/22/04 08:35AM >>>
This is a known issue for the release version of Struts1.1, but if you
download a nightly build after Sep 24 2003, the required validation
will
work.

Hi all

Is there an out of the box struts-validator way to check to see if at
least one of x number of checkboxes has been checked using the
html:multibox?

I have been attempting to use the required and requiredif rules to no
avail.

Background:

Struts 1.1
DynaValidatorActionForm
Tomcat 4.1

Thanks in advance

Justin

This is a known issue for the release version of Struts1.1, but if you
download a nightly build after Sep 24 2003, the required validation will
work.

Re: multibox - Null attribute name ServletException - SOLVED

[ZYD]

I change html:iterate tag to:



the ="multiboxTest"  is the ActionForm bean's name in struts-config.xml.

and add getter/setter for items, now it works.

Thanks.

RE: Multibox over a collection

So

Then each row is identified somehow (indexed?). Each row will need to
have 
that checkbox named (property) exactly the same way on each row, but you
can assign a different value (suppose index value) to the checkbox of
different row. Your form that accepts values from html request will need
to have String [] property that will be filled with indexes of checked
rows upon submission.

Re: Multibox persistence problem

[David Chelimsky]

I was under the impression that we were talking about the question of 
persisting the Collection on a validation error. You've got 
validate="false" in the mapping below, so it's not validating. If you 
set validate="true", I'm almost certain that you'll lose allRoles unless 
you set the scope to "session". Please yet us know if you get a 
different result.

Thanks,

1. Make sure that you are overriding the reset() method in the
   

ActionForm.
 

2. In reset(), make sure you do NOT reset the value of the Collection
that contains your multibox options, but make sure that you DO reset all
other values besides your Collection.
3. set scope="session" as was suggested
The result is that your Collection gets set in your Action and left
alone on validation failure. The other properties are handled per the
quote you referenced below.
As for why it is that Struts doesn't repopulate the Collection for you
   

from the request, essentially it has no way of knowing that they exist
 

as they are not in the request when you submit the form. Only the values
you select are. This is not true of text inputs because they return
empty strings, but are still present in the request. I imagine something
could be added to Struts that would add a bunch of hidden fields to the
form in your .jsp that could somehow describe the type of  the members
of the Collection, and then rebuild the collection on the fly based on
those fields. Perhaps this would make more sense after java 1.5 is
released with support for typed Collections.

1. Make sure that you are overriding the reset() method in the ActionForm.
2. In reset(), make sure you do NOT reset the value of the Collection 
that contains your multibox options, but make sure that you DO reset all 
other values besides your Collection.
3. set scope="session" as was suggested

The result is that your Collection gets set in your Action and left 
alone on validation failure. The other properties are handled per the 
quote you referenced below.

As for why it is that Struts doesn't repopulate the Collection for you 
from the request, essentially it has no way of knowing that they exist 
as they are not in the request when you submit the form. Only the values 
you select are. This is not true of text inputs because they return 
empty strings, but are still present in the request. I imagine something 
could be added to Struts that would add a bunch of hidden fields to the 
form in your .jsp that could somehow describe the type of  the members 
of the Collection, and then rebuild the collection on the fly based on 
those fields. Perhaps this would make more sense after java 1.5 is 
released with support for typed Collections.

Doesn't work with session scope too.

"As we know, Struts redirects to the path set in the "input" attribute for
the action if there are errors present in ActionError object.
The ActionForm object holding the user's data will still be in request.
Thus, any data entered by the user in the form will appear pre-populated in
the form."
All the data in  tags is pre-populated well. But multibox -
not...
Any suggestions?

Hi,

I'm using multibox to display multiple checkboxes:




  




Everything works fine, the only problem is - when there's a validation
 

error
   

on my form and it's reposted with error messages, it always return all
checkboxes unchecked (even if I check some of them before).
How could I keep checkbox values in this situation?

RE: multibox problem - No getter method

[Sterin, Ilya]

Make sure you have the first letter as lower case, in your jsp file, so
say...

public void setAcChecked(...)
public String[] getAcChecked(...)


in jsp make sure that it's acChecked, as it will append and get or set and
capitalize the first letter.

Hello,

I would like to present an input form on a jsp and part of that would be to

To provide different sets of labels and values, the standard LabelValueBean

Not having seen the context of Ted's writing, that would be my guess.  Observe however 
that this will work only in Struts 1.1.  You've said that you are using 1.0.2

Re: MultiBox problem.

[Susan Bradeen]

Kavitha,

I am not sure about your specific error, but you should use a String array 
instead of ArrayList. At least give that a try and see how far you get. 
There is quite a bit of information on the multibox in the list archives.

Hi,
  I am using a multibox as follows in my JSP page:










where unAssignedorgs is an ArrayList contaning standard LabelValueBean.

when I run this I get the following error:
"Cannot serialize session attribute unAssignedOrgs".

I am using this in JBuilder 7.0.
Has anybody encountered this ?Is it because I am using an ArrayList?
Any help is highly appreciated.

simply invoke the default constructor.

How are you "setting the selected string array in Action class"?  Are you creating 
this form bean in the Action class then setting the array?  If so, are you persisting 
this form bean to some scope (request/session/application)?  If you don't and if the 
Struts framework doesn't find one in some scope it'll simply create one -- by calling 
the default constructor.

Subject: multibox : problem with preselected array


Hi,
 
I have been trying to use multibox and am facing a strange problem. I want a few 
values to be preselected when I load the form. If I initialize my selected string 
array in default constructor of the form then 
everything works properly and I can see those checkboxes as selected when the form 
loads. On the other hand if the selected string array is populated in an overloaded 
constructor then no checkbox is selected ?? Even setting the selected string array 
in Action class doesn't help :-(
 
Anyone where am I going wrong ? 
__
The form has :
 
 private String[] selectedItems;
 private String[] items;
 
 public void reset(ActionMapping mapping,
  javax.servlet.http.HttpServletRequest request) {
  selectedItems = new String[0];
 }
 
 public TestForm(boolean flag)
 {
  if(flag)
  {
   selectedItems = new String[1];
   selectedItems[0] = "FedEx";
   items = new String[3];
   items[0] = "FedEx";
   items[1] = "UPS";
   items[2] = "Airborne";
  }
 }
 
 and the corresponding getter ad setter methods.

the jsp has the following code :


  

   




Thanks,
Sanjana

That will work, but... what if you have a form that you don't want to
validate?  The reason this is working is that you have validate set to true
so that the validate method gets called.  If you set validate to false,
it'll stop working.

One line in your reset method will do the same thing:
   isOn = false;

The reset method will autmatically get called before the set-methods for the
successful form elements.  So if the checkbox isn't checked, the isOn
property will remain false.  If it is checked, then the setIsOn method will
be called and isOn will be set to true.

For the sake of the person who has to maintain your code later on, (not to
mention your own sanity when you look at this in six months,) use the
validate and reset methods for their intended purposes. :)

Re: multibox, checkbox PROBLEM FOUND, SOLUTION NOT!!!

[kiuma]

Thanks a lot , you have been very clarifying.

I've found a tip placing code in validate method :

public ActionErrors validate( ActionMapping mapping, HttpServletRequest 
req) {
  
   String str = req.getParameter( "isOn" );
   if (str == null)
   isOn = false;
   return null;
   }

But it's a very dirty technique of course.

When you submit the form, only "successful" form elements are sent in the

checkboxes will be present in the request.

Isn't this what the "reset" method is all about?  The reset method will be
called before Struts automagically populates all of your ActionForm fields.
I can't tell what your Collection is from this post, but try clearing out
*all* of the values in the Collection that handles your checkboxes in the
reset() method of the Form.

Then, if you uncheck all of the boxes and submit, you should see that none
of them are checked when the form is redisplayed (or you use the data).

Hope that helps,

Wendy's correct, according to

"WARNING: In order to correctly recognize unchecked checkboxes, the
ActionForm bean associated with this form must include a statement setting

Re: multibox, checkbox PROBLEM FOUND, SOLUTION NOT!!!

[kiuma]

Ok suppose to have a Form with a checkbox named "isOn" and a submit 
button name "Save"

a NOT checked value will produce:
http://localhost:8080/webappointments/openChk.do?action=Save

a checked value will produce:
http://localhost:8080/webappointments/openChk.do?isOn=on&action=Save

The problem is that if I have a checked value that I want to turn off 
I'll send
http://localhost:8080/webappointments/openChk.do?action=Save
the form function
   public void setIsOn( boolean isOn )
   {   
   this.isOn = isOn;
   }  
is not called and the value will not be changed.

Where am I wrong ??

RE: multibox problem

[Karr, David]

The property associated with a multibox is not a collection.  It's just a
scalar.  Look at the "struts-exercise-taglib" for simple examples of this.

RE: multibox validation and collections

[Zimmer, Robin (SSABSA)]

F.Y.I. I resolved my problem by setting the 'input' value of the
struts-config action mapping to the action that initialised the form bean
(then forwards to the jsp) rather than the jsp directly. 
PS. Thanks for your response.

If your form's validate method returns errors, then the Struts
controller servlet immediately forwards the user to the page specified
in the input="xxxpage.foo" attribute for the current action in
struts-config.xml.  Your own action class is not invoked this time, so
any setup it might have done in request scope for your JSP (such as
populating lists for your dropdowns) is not performed.

Putting your setup in session scope will solve that problem, but
create another: you'll end up with a lot of JVM memory being pinned
down for lists that users don't really need anymore.. and trying to
come up with logic to clear out old lists from the session when
they're no longer needed is a losing battle. :)

I've tried to make my JSPs independent of action and form setup
(because of the way form validation works). A good clean way to do
that is to put getListOfXXX() methods on your business objects where
needed, and use those methods directly in the JSP when you need
Collections for  and .

I hope that helps, and I hope I answered your question. :)

PS: ActionForm is serializable, but I still wouldn't recommend keeping
lots of forms in session scope because of the memory issues.
Check out http://jakarta.apache.org/struts/api/index.html for 
everything you ever wanted to know about the struts classes (that's
where I went to double-check that ActionForm is serializable).

RE: multibox bug (Help needed)

[Mark Nichols]

You haven't given us enough information to solve your problem for you. I
suggest you reexamine the action that precedes this JSP to make sure that
the proper bean is placed in the proper context under the proper name.

If you want help I also suggest that you read the "How to Ask Questions"
link listed on the Struts site.

Re: Multibox intial selection problem

[Nicolas De Loof]

A cleaner (IMHO) way for generating such select in HTML would be :





... where "monthstosaveValues" is a collection of objects that have "value"
and "label" property (attribute+getters) for your select box items (that
could be placed in application scope if it is constant between users).

If "monthstosave" property of your formBean has a value, it will be
automatically preselected in generated HTML.

You can find more about html:options use in
http://jakarta.apache.org/struts/doc-1.0.2/struts-html.html#options

Search for  "how to set  initially the value of multibox to selected."

You misspelled the property name in the "html:multibox" tag.  It should be
"daysOfWeek", not "daysofWeek".  If it's really spelled correctly in the JSP,
and you just mistyped it in this note, then I don't know what the problem is.

RE: Multibox in iterate

[Tricia Ong Cheah Yen]

and how do u set the values for ? 

i had managed to create a list of  checkboxes but the "checked" status
isn't initialized at all, meaning, whatever checkboxes that were
selected by users were not reflected in the checkboxes when the user
returns to the same page again after successfully updating the database.


   ,



in UserForm, the getter & setter methods of accessList are as such:
public String[] getMgrAdminAccess() {
return this.mgrAdminAccess;
}

public void setMgrAdminAccess(String[] inMgrAdminAccess) {
this.mgrAdminAccess = inMgrAdminAccess;
}

You should add the "name='role'" attribute in the  tag.
When you think about it, it is logical.

make sure in your ActionForm class, you have an attribute called testChecked
and coresponding getter/setter

Hi

I iterate through a collection without any problem, but now I want to add a

If I remove the multibox tag I iterate successfully, but with the iterate

Re: multibox - i know is easy but i am lost!!!

[simon]

Raul,
Did you did you work out the solution to this,

I think what you need to do is for the Form object that you've defined 
that maps this form you need a property that relates to the multiple box
e.g.
if i have a jsp  mainmenu.jsp
with




Then in my form handler
i need bean property that reflects this. e,g,

public final class MainMenuForm extends ActionForm {
public String[] blah;// for multi select

public String[] getBlah() {
return this.blah;
}
public void setBlah(String[] _blah) {
this.blah = _blah;
}
...etc
}

let me know if this isn't clear, otherwise
check out
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg16260.html
could help...?

You need to implement the reset() method, as Erik has mentioned. It was

RE: multibox and reset() "ERIK"

[Krueger, Jeff]

I haven't tried the reset method, but I am setting the default
values in the constructor.  I'm not sure how those two will help with my
problem though.  Maybe let me try and explain it a little more.  I go to the
page for the first time and the formBean is created, everything is blank and
ok.  The user then selects 4 out of ten boxes and submits the form.  So now
I have a string array with 4 items in it.  The user returns to the page and
those four items are then selected out of the ten.  Then the user unselects
all items and submits the form.  The form has already been created so the
constructor shouldn't fire and since there are no check boxes selected or
submitted the setMethod won't get called and I will be left with the same
array of four items.  Maybe I should have had them reset the form instead of
submitting a empty one here?  So this is where I added the code to my action
to see if no check boxes were submitted and then call the set method and
pass in a string array of length 0.

Re: multibox and reset() "ERIK"

[Erik Hatcher]

The better way is just what was mentioned set your values to null
(false?) in the reset method.   But if you are using Struts 1.0 and not a
more recent build, also setting them in the constructor or initial values
when defined is a good idea to default them in the case you are navigating
directly to the JSP page rather than going through a Struts action to get to
the JSP page.

So more succintly, initialize values in reset and that should fix the issue
you described.   Did you try that?

Thanks Erik for the extra info.  I was thinking that was the problem I was
having.  One idea that I had was to check in my action class to see if any
check boxes were on the request and if not then call the set method myself
setting it to null.  Does anyone know of a better way to do this.

Jeff,

No, my patch did not fix this particular case.   Here is what is happening
in your scenario: checkboxes do not submit a value if they are unchecked,
therefore Struts has no way of knowing of their existence on the original
HTML form and thus does not call any setters.  The reset method is where you
implement setting all your checkboxes (and likely other HTML field types) to
their default (false, in your case) value.

My patch was for the case where the ActionForm bean was created by a JSP
page rather than ActionServlet, and reset was not called at that point.   In
your case, the ActionForm bean is being created (in the last request you
speak of) by ActionServlet, so reset should be called - this is all assuming
you are going through a Struts action for that request.

My patch has been committed to Struts CVS, so its available in the nightly
builds (I presume, unless those builds are running on a different branch or
something).

RE: multibox and reset() "ERIK"

[Krueger, Jeff]

Erik,

I believe your patch will solve my problem but I'm not sure.  I have
a page with many multibox tags on it.  When I select several of them my form
bean is correctly populated with a string array.  If I come back to the page
all the correct boxes are checked.  If I remove all the checks and click
submit then my string array is left to what it was before.  I assume this is
because there is no mutliboxes being submitted to the server, therefore the
setMethod is never getting called.  Is that what you patch fixed, if so do
you know the status of that making it into a build?

Thanks

Jeff

reset is currently not called if  creates the form bean, which
happens if you go to the JSP page directly without hitting ActionServlet
first.

Antw: RE: multibox always checked

[Marion Schwarz]

Yes, that's what I figured out at last.
One more question:
I notice that even objects in session scope cannot be used by different frames.
When my frameset is built, the first frame contains a jsp page which is called with a 
parameter. This page puts the parameter in session scope. 
The second jsp page uses the same parameter, but it can't fetch it out of the session 
scope.
It looks like this:

frameset
--
  

  
  


  



logon.jsp
-
<%
String senderParam = request.getParameter("sender");
pageContext.setAttribute("sender", senderParam, PageContext.SESSION_SCOPE);
%>


index.jsp
--
<%
String senderParam = pageContext.getAttribute("sender", PageContext.SESSION_SCOPE);
%>


Why doesn't this work ?

Stranger still: When I call index.jsp?sender=86 and fetch the parameter with 
request.getAttribute("sender") I still don't get it.
This worked earlier, but now everything's messed up.

Please help me.
Thank you all.

RE: multibox always checked

[Hans Gilde]

I don't have a direct solution to our problem but why not submit the
checkbox form, targeted to the frame that's supposed to display the total?
An action can count the check boxes and display the total page without
having to refresh the form every time. The form can also use a JavaScript
timer to wait 3 or 4 seconds after a box is checked before refreshing the
price; every time a box is (un)checked, the timer is reset to prevent
multiple refreshes to the price frame.

Also, http://www.alienware.com/main/configurator_pages/custom.asp has a
pricing system that doesn't use frames.

Subject: multibox always checked


Hi folks,

after reading a million postings on the subject, I still have a question.

When a checkbox is selected, I want to count the selected object in a
different bean.
The total amount should be displayed immediatly in another frame so I have
to submit my form every time a checkbox is selected or deselected ( I would
be glad to hear of a better solution ).
My form revalidates correctly so that only checked multiboxes are truely
checked - with one exception:
The first of my checkboxes is always checked.

Does anybody have a clue to this phenomenon ?
Thanx in advance.

Re: multibox and reset()

[Renaud Waldura]

The signature for reset() is the following:

void reset(ActionMapping, HttpServletRequest)

I don't know whether setting the array reference is null is enough, or you
truly need to create a zero-length array like in your example below.

I set mine to null, it seemed to work.

I just got it working!  I got my form working in the same fashion you had 
yours.  One of my problems had been with not importing the bean taglibs 
properly (as my face turns slightly red) and I had tried to put the empty 
values of one of the arrays in my form to be null when a box shouldn't get 
checked, and that was causing a null pointer.  Anyway, thanks SO MUCH for 
your replies, they helped a lot.

  It sounds like you are getting close to what I'm using. I'm only
iterating over the String[] that contains all the possible values.
Values in the other String[] that match the array you are iterating
over will cause the checkboxes to be set to checked (but you don't need
to iterate over this second String[]). Also make sure the array you are
iterating over always contains all of the possible attributes, either by
saving it in session scope or repopulating it each time in request scope
(i.e., don't set it to null in reset()). In the ActionForm, I have:


 private String[] findAssets = null;
 private String[] selectedAssets = null;

/**
  * Get
  */
 public String[] getFindAssets() {
   return (this.findAssets);
 }
/**
  * Set
  *
  * @param
  */
 public void setFindAssets(String[] findAssets) {
   this.findAssets = findAssets;
 }


/**
  * Get
  */
 public String[] getSelectedAssets() {
   return (this.selectedAssets);
 }
/**
  * Set

 public void setSelectedAssets(String[] selectedAssets) {
   this.selectedAssets = selectedAssets;

  Hello Becky. I flailed around with multibox myself before I found
something that worked. In the example below, I implemented two String[]
arrays in the ActionForm, "findAssets" and "selectedAssets". findAssets
maintains all of the possible values and selectedAssets maintains the
currently selected values. Iterate over all the possible values to print
the checkbox name and use the property setting of the selected values to
set the checkboxes.


  
   
  
  
  



Hope this helps.

 Hello Becky. I flailed around with multibox myself before I found
something that worked. In the example below, I implemented two String[]
arrays in the ActionForm, "findAssets" and "selectedAssets". findAssets
maintains all of the possible values and selectedAssets maintains the
currently selected values. Iterate over all the possible values to print
the checkbox name and use the property setting of the selected values to
set the checkboxes.


 
  
 
 
 



Hope this helps.

The bug you mention concerns the multibox rendering. But my problem with the
multibox tag is as follows. The following line in the jsp work fine as is.
That is, it produces the expected html.



My problem occurs when the form is submitted. The "checkbox" array property
in my ActionForm is not populated with the values that have been checked.

RE: multibox

right now multibox does not cooperate with the iterator,
The text in the value field is not evaluated, it is static.

Are you saying the multibox tag doesn't work at all now?  From reading the
documentation, I don't
understand how it should work now.

This doesn't work yet, I submitted a patch

Vote for bug #402 at
http://nagoya.betaversion.org/bugzilla/show_bug.cgi?id=402

With my patch the usage is

Now your form needs to have 
public String[] getCheckbox() {...}
public void setCheckbox(String []) {...}

I wonder if someone could give me an example of the multibox usage.
If I have something like this in my jsp:


...

What do I need in the ActionFormBean for this jsp with respect to the
checkbox property?
Thanks for any info.
