Using multibox to indicate checked value

[Odelya Yom-Tov Glick]

Hi guys

I have this ActionForm

public class InterestsForm extends ActionForm {
private String[] selectedItems = {}; 
private String[] items = {"business","htech""};
  private String[] userPreviousSelectedItems= {"business"};
public String[] getSelectedItems() { 
  return this.selectedItems; 
} 
public void setSelectedItems(String[] selectedItems) { 
  this.selectedItems = selectedItems; 
}

}

And this form:




" />



I would like to check the items that the user checked previously and I
stored them in userPreviousSelectedItems (I can also create a collection
instead).

How can I do it?

Thanks

Odelya

Map based Struts Action Form and multibox Issue

[MoorthyHome.com]

I am using map based Struts action form 

Something like below...

public FooForm extends ActionForm {

private final Map values = new HashMap();

public void setValue(String key, Object value) {
values.put(key, value);
}

public Object getValue(String key) {
return values.get(key);
}

}

In Jsp I have something like below

  
 
 


  

Map based Form works well for others except multibox or select with
multiple=true

In setValue, The Object value always String and not String array that is
what I expect for multibox or multiple select

Since this is String, the form is selected with just one selection the first
selection..

Please help

struts action form vs # of multibox fields determined at runtime

[john feng]

I have a jsp page that produces a matrix page based on database queries for
both column header records and row records. The column and row crossed
fields are displayed as multiboxes, i.e., each vertical column of those is a
multibox field named as "crossCheckBox0", "crossCheckBox1",
"crossCheckBox2", ...starting from left to right. The number of those
columns is determined at run time by database queries.

If the number of fields is known at design time, then they can be added in
to action form as String[] attibute, then one may take advantage of that
struts would determine how many of the vertical boxes(rows) are checked at
runtime.

But now the number of mutlibox fields are dynamic and not design time
determined, it is an unknown dimension array like crossCheckBox[#][#]...[#]
where # stands for the number of rows being same. How to represent it in
action form?

Currently I have used javascript to loop thru the table to find out the each
column's checked boxes and could not take advantage of struts multibox
feature. Since I don't know how to add them into action form, I changed them
into pure html .

May anyone have experienced this issue before and would like to shed some
light on it? I would appreciate a ton for the insight.

RE: RE: RE: [HELP] struts 1.2.9 multibox/checkbox in session scoped form

[Lance Semmens]

RequestProcessor is doing it's job by resetting the form. What should then 
happen is that your checkboxes should be set after reset() is called which 
doesn't seem to be happening.

Somethings not right here, esp since when you comment out reset, it works. Can 
you post your code? pls. include the relevant parts of struts-config.xml, your 
action and your form.

The only thing I can think is maybe you're explicitly calling reset()
in your action (instead of letting struts do it automatically). If
not, I suggest putting a debug breakpoint on the setters for your
checkboxes and see what's going on.

1. Yes
2. Yes
3  In ActionForm.reset

If I comment out my reset method then it populates the checkboxes
based on the form values like I want however I then loose the ability
to only get the checked value put into my action form after the page

I'm not sure I understand the question, but it sounds like you're not

Post your JSP code if you can't get it figured out.

Re: Check a multibox dynamically

[Uday Karrothi]

Hi thre,

I am trying to give you an example.  Multibox basically fills in using a
string array. i am sure you are aware of that.



   
   


in the code " toBeAddedList" is the string array in the form bean that has
the userID's of the selected users. So, when the check boxes are being
checked , if the userID()
is present in the string array then the checkbox is checked. else no. And
when you try to retrieve the array in the action form the string array
contains all the userID's selected.
in the action form you can set the array and the multibox is populated.
 toBeAddedList[i] = .getUserID();

you can even set the checkboxes in the Javascript
function checkAllToBeAddedList()
{

As Adam J. mentioned, it sounds like you're using a session-scoped 
bean.  Try overriding (if you haven't already) the reset() method of 
your form bean and resetting the property:


public void reset( ActionMapping mapping, HttpServletRequest request )
{
   this.values = new String[0];
}

If you're _not_ using a session bean (and are using a request-scoped one 
instead), you'll _still_ want to do the above.  Using this way in both 
cases, values from the previous request are discarded.  If the web 
browser doesn't send any checkbox values over (because none are 
checked), then this.values will be an empty array, which corresponds to 
the very state of the submitted form's checkboxes (ie: none are checked).


The array of values in your formbean for an html:multibox are a list of 
values of checked checkboxes. So...


1. Form bean looks like this:
this.values = { "value1", "value3", "value5" };

2. Displayed form looks like this:
value1 1
value2 2
value3 3
value4 4
value5 5

3. HTML sent to browser looks like this:
 1
 2
 3
 4
 5

4. User unchecks ALL checkboxes, and submits the form.

5. Struts calls reset() on your form
   - Your reset() method sets this.values = new String[0]

6. Struts populates your form, and _doesn't touch "values"_, because 
nothing is checked, so values remains an empty array.


Sound good?

Re: multibox not works when all checkboxes are unselected!

[Truong Xuan Tinh]

   That's what you have to do, as Adam said, the browser won't send the
value of unselected checkboxes. The sequence for create your form bean
are : Create, Reset, Populate, and Validate. You should override the
Reset method of the ActionForm to make sure that your form bean accept
new value from the browser.
Hope this may help. ;)

RE: multibox not works when all checkboxes are unselected!

[Samere, Adam J]

Browsers are only required to submit values for checkboxes when they are
selected. So when a box is not checked, no value is sent, so the state
on the server is not changed. When using session scoped objects to store
the value of checkboxes your processing needs to be aware of the fact
that values for "checkbox=off" are not sent.

one or two or three it arrives correct
at the next action!
Only then all checkboxes are deselected
it remembers the state of the checkboxes that was selected before! The
state of the form is session in struts-config.
Can you help me with this problem??
I really don't have an idea how to solve it!

Thanks a lot!

My fault :-(. I didn't recognize the closing ">" after the property-value.
Now, it's working fine. Thank you to both, Tarun and Rick, for your great
help!

Is the component  above used as nested body
content of the html:multibox tag?

The get-/setDeaktserver backing form is used in the iterate-tag. The
backing form for the multibox is inaktmachines, which is an Array .

I'm fairly certain your backing form bean property needs to be an array 
(String[] typically) and not a List for a multibox. (I might be wrong,

Lets say I have the following multibox:





 
 






I have a List of POJOs with a name and a boolean value for each POJO.  I want 
to change the boolean value to true if a user check marks a specific item in

If I wasn't in struts I could easily do this if I were using a Servlet. But how

Multibox problem

[Shyam . Tummala]

Hi-

I am having a problem with repopulating multiboxes.

Scenario:

My application is a wizard based one. User clicks on a couple of 
checkboxes(multibox) and does a submit and after a couple of screens he 
wants to come back to the checkboxes screen and the way i do is, i save 
the values he clicked and then when he wants to come back i store those 
values in a list and then to the request with the same name as that of 
multibox, but the multiboxes are not selected and there is no tag in 
multibox using which i can say that.

For Eg:

My JSP page:

10Kansas City
11Dallas
12San Francisco

My form Bean:

private String [] districtIds = null;

public void setDistrictIds(String [] districtIds) {
this.districtIds = districtIds;
}

public String [] getDistrictIds() {
return this.districtIds;
}


Code where i put the values back:
map.put("districtIds", stringArr);
where stringArr is an array of what the user selected.

Thanks,
Shyam.

One reason could be that you defined the accompanying form with 
scope="session". If so, are you sure you need this? Then again, it could 
be that a method is pre-populating the checkboxes by retrieving the 
relevant values from the database that you just inserted. Can you post 
more code?

Re: Multibox

[Robert Taylor]

The multibox is "bound" to the selectedModule property of your form.
Prior to displaying the page, populate selectedModule property of the 
form with its corresponding row.id values. When  is 
invoked on the page, it will "recongize" the relationship and render the 
checkboxes as checked.

Can anyone let me know how to automatically check checkboxes?
Set the underlying form property and the framework will automatically render 
"checked" checkboxes.

I have:

  
   


The form property "accounts" is a String[] containing account numbers.  So 
this displays all of the accounts in accountMap, and 'checks' the boxes next 
to the ones that match the values in the "accounts" form property.

Re: map-backed forms with multibox/multiselect lists?

That's great! Thanks for sharing.
Next time I'll know how to do it. Luckily you proved to be more 
determined and finally solved it. Congratulations!

The good news is that this DOES work.
I simply declared my methods to be
public void setFoo(String key, String[] foos)
{
...
}
public String[] getFoo(String key)
{

}
and everything works fine. It took a detour through the Struts
source (and ultimately from there through the beanutils source)
to figure this out, but the problem was essentially that when
doing the bean introspection, the beanutils first finds the getFoo()
method and stores its return type. It then looks for a setFoo()
method with the same argument type as the return type of getFoo().
If you try to return foo as an Object, it just won't work -- your
setter won't be found and the method will never be called.
thanks for the input,

I had the same problem some time ago (the solution vaguely

my problem...
I'm guessing this might be some sort of a problem with 
commons-binutils 
(although public void setFoos(String key, String[] foos) 
isn't a valid 
javabeans setter so maybe it's just a bit out of it's scope).

RE: map-backed forms with multibox/multiselect lists?

[Nidel, Mike]

The good news is that this DOES work.

I simply declared my methods to be

public void setFoo(String key, String[] foos)
{
...
}

public String[] getFoo(String key)
{
...
}

and everything works fine. It took a detour through the Struts
source (and ultimately from there through the beanutils source)
to figure this out, but the problem was essentially that when
doing the bean introspection, the beanutils first finds the getFoo()
method and stores its return type. It then looks for a setFoo()
method with the same argument type as the return type of getFoo().
If you try to return foo as an Object, it just won't work -- your
setter won't be found and the method will never be called.

thanks for the input,

Mike

RE: map-backed forms with multibox/multiselect lists?

[Radu Badita]

I had the same problem some time ago (the solution vaguely suggested by 
Jack wouldn't had been an option since the properties were dynamic so I 
needed the key to distinguish between them). I asked on this list for help 
at that time, but didn't got an answer, so I guess nobody succeeded in 
doing something like this. Therefore I had to find some other solution to 
my problem...
I'm guessing this might be some sort of a problem with commons-binutils 
(although public void setFoos(String key, String[] foos) isn't a valid 
javabeans setter so maybe it's just a bit out of it's scope).

At 16:44 07.03.2005, you wrote:
This works fine for list-backed form items (which we also use)
but in this case I need something like
public void setFoos(String key, String[] foos)
is this possible?
There are several workarounds I can think of, but this appears
to be the cleanest solution if I can make it work.

RE: map-backed forms with multibox/multiselect lists?

[Nidel, Mike]

This works fine for list-backed form items (which we also use)
but in this case I need something like

public void setFoos(String key, String[] foos)

is this possible?


There are several workarounds I can think of, but this appears
to be the cleanest solution if I can make it work.

map-backed forms with multibox/multiselect lists?

[Mike Nidel]

I'm trying to build a form element that combines the features of a map-backed
property with a multibox (and the same for a multiple-selection list). I've made
multiboxes work fine without the map-backed element, but I can't seem to get
this to work.

I've tried various method signatures in my form bean, but to no avail. For
example, for a field called "foo" I have tried the following:

public void setFoo(String key, Object val)
{
...
}


or


public void setFoo(String key, String[] val)
{
...
}



I'm using a set of checkboxes on the JSP which should result in a list of the
values of whichever boxes are selected. I can think of a number of javascript
workarounds, as well as workarounds in my Action that go directly to the request
parameters... but all of those are kludges and it seems like there should be a
way to have multiple checkboxes that all reference a map-backed form property.


Any thoughts?

thanks a bunch,

Mike Nidel

RE: creating a for loop structure for multibox

[David G. Friedman]

Frank,

I'll agree with you on not wanting taglibs to be tied directly into Struts.
Why?  Because I like the idea of modularity.  I think this comes from
skimming over struts-chains and thinking (GASP) there are things I could do
without using the traditional struts at all. *shivers in fear AND excitement
at that idea*

Just my $0.02 worth.

Regards,
David

Yeah, your right about the Struts tags, but I always worry that there
might be something under the covers that ties it to Struts.  Sure, I
could look at the source, but I've never wanted to know that bad :)

Eh, I knew I was saying something controversial to begin with :)  I'm in

Re: creating a for loop structure for multibox

[Frank W. Zammetti]

It's also fair to tell you that you can do the same thing with JSTL and 
NOT be tied to Struts (assuming you abstract the ActionForm a little and 
don't do anything with it that can't be done with a normal bean later). 
 Kind of a best of both worlds answer I guess, but I think JSTL tends 
to be just a hair more complicated (not much, but a little).

Subject: Re: creating a for loop structure for multibox
If I understand correctly, you will get from an Action an 
upper limit to 
the number of checkboxes to display, and you want each checkbox to be 
named 'valueX' where X is the value of the for loop.  Some 
people will 
argue, but I don't see where a taglib is really required here...

<%
  // Assume you got a reference to your action form in af,
  // and that is has a getUpperLimit() method...
  int ul = af.getUpperLimit();
  for (int i = 0; i < ul; i++) {
%>

<%
  }
%>
Not much more than that required.  To make them retain state, you'll 
have to provide some method to determine when a given checkbox is 
checled, and add a checked attribte accordingly, something like:



That'll do the trick, assuming getIsChecked() accepts an 
index value and 
returns a boolean stating whether that particular checkbox is 
checked or 
not.

I have a personal distaste for taglibs in most cases, I know 
many people 
disagree, but I figured you might as well know all your options, then 
you can choose whickever you prefer from an informed position.

And in that spirit:

 

is 4 lines of code
plus the 3 lines of code you'll need in reset.  Plus the i18n ability with no 
additional codeing.
Not to mention being able to hand off the code to the web design folks and have 
them easily make things purty.

Subject: creating a for loop structure for multibox
Could someone please post an example of using a 'for loop' 
structure in 
 

Using JSTL, or Struts tag libs?



a JSP. i need to get the loop limit from the action and 
then assign 

individual 'value' values for a column of checkboxes so 
that i know 

which ones were selected and so that they can be set again 
when viewing 
the page.

thanks

The List would contain the values.  As you iterate over the List, for each
multibox, the Struts framework will render it as checked if its value
matches one of the values in the String[] that's in the Form bean.

   
   



This uses a Map which is sitting in session scope.  Yours might be a List, I
think any Collection would do. In the example, 'accounts' is a String[]
property of the Form bean.

And in that spirit:


 

is 4 lines of code
plus the 3 lines of code you'll need in reset.  Plus the i18n ability with no 
additional codeing.
Not to mention being able to hand off the code to the web design folks and have 
them easily make things purty.

RE: creating a for loop structure for multibox

[Jim Barrows]

>From the struts multibox documentation:
Renders an HTML  element of type checkbox, whose "checked" status is 
initialized based on whether the specified value matches one of the elements of 
the underlying property's array of current values. This element is useful when 
you have large numbers of checkboxes, and prefer to combine the values into a 
single array-valued property instead of multiple boolean properties. This tag 
is only valid when nested inside a form tag body.

WARNING: In order to correctly recognize cases where none of the associated 
checkboxes are selected, the ActionForm bean associated with this form must 
include a statement setting the corresponding array to zero length in the 
reset() method.

The value to be returned to the server, if this checkbox is selected, must be 
defined by one of the following methods:

* Specify a value attribute, whose contents will be used literally as the 
value to be returned.
* Specify no value attribute, and the nested body content of this tag will 
be used as the value to be returned.

Re: creating a for loop structure for multibox

[Frank W. Zammetti]

If I understand correctly, you will get from an Action an upper limit to 
the number of checkboxes to display, and you want each checkbox to be 
named 'valueX' where X is the value of the for loop.  Some people will 
argue, but I don't see where a taglib is really required here...

<%
  // Assume you got a reference to your action form in af,
  // and that is has a getUpperLimit() method...
  int ul = af.getUpperLimit();
  for (int i = 0; i < ul; i++) {
%>

<%
  }
%>
Not much more than that required.  To make them retain state, you'll 
have to provide some method to determine when a given checkbox is 
checled, and add a checked attribte accordingly, something like:



That'll do the trick, assuming getIsChecked() accepts an index value and 
returns a boolean stating whether that particular checkbox is checked or 
not.

I have a personal distaste for taglibs in most cases, I know many people 
disagree, but I figured you might as well know all your options, then 
you can choose whickever you prefer from an informed position.

bu then even if i pass the iterate tag a list of same lenth of required 
number of checkboxes, how would i make sure each checkbox has a unique

public ActionForward execute(ActionMapping _mapping, ActionForm _form,
HttpServletRequest _request, HttpServletResponse _response) throws

{

DynaActionForm dynaForm = (DynaActionForm) _form;

String userId = (String) dynaForm.get("userId");

String[] companies = MyDBTools.getUser(userId).getCompanies();

You will need to set the "selectedCompanies" in the ActionForm
so that the  can determine which companies
have been selected by comparing the company id against the selected
company id.

If "allCompanies" does not change per user, you may want to place that
in 
the ServletContext on application startup to avoid the database hit
everytime that action is executed.

How I can prepopulate a form containing a multibox when using
DynaActionForms? The following code doesn't seem to work - it wont check
any checkboxes (why?)

---
Action which prepopulates the form:
---

String[] companies = MyDBTools.getUser(userId).getCompanies();
ArrayList allCompanies = MyDBTools.getAllCompanies();

_request.setAttribute("selectedCompanies", companies);
_request.setAttribute("allCompanies", allCompanies );

use disabled instead of readonly.
IIRC , HTML rarely uses readonly -- its mostly disabled attribute everywhere.

RE: Multibox deselection problem

[Seetamraju, Uday]

For simple use-n-throw (non-dynaforms?) forms, a much better *generic* solution 
:-

At the VERY BOTTOM (please note the caps to get your attention ;-) ) of the JSP 
that displays the form :-

<%  MyForm frm = (MyForm) request.getAttribute("formname");
frm.reset();
%>

In scenarios where the user can "temporarily" navigate to other pages and comes 
BACK to this page the user will find all values gone...
So, it works wonderfully ONLY for use-n-throw forms.
>From my experience, forms with such checkboxes are not on the 'main page' 
>(that the user keeps coming back to for all screen flows).

All my forms are explicit bean-classes, -- others can let you know if reset() 
works on dynaforms.
And do not forget to code your reset() function.

Re: Multibox deselection problem

[Olivier Croisier]

Hi !
Thank you for you help, it works fine now !
BTW, it seems like Struts does not support all standart HTML options : I had to use a pure HTML 
 tag because the "readonly" attribute does not exist in Struts, and I 
think this mix is a bit dirty. But it works...
("onLoad" not supported either...)
Olivier Croisier

This is a problem with HTTP: when all the checkboxes are deselected, the
browser doesn't send anything back, so you get the default of what you
started with. To solve this problem you must ensure that at least one box is
always selected.
I solved this problem by creating an additional checkbox that is hidden,
read-only and selected. This will ensure that the browser sends something
back.
String[] defaultEntities = {"A", "B", "C", "D", "filler"};

Hi Robert!

Thanks for your answer. It pointed me to the problem. I used the add instead
of addAll of the Collection-interface. So instead of adding the elements
(Strings) I added the collection as a collection.

How many items are in the "func" data structure in request scope?

Multibox problem

[Roland Carlsson]

Hi!

I'm trying to create a set of checkboxes with the MulitBox-tag.

The problem is that I get an extra checkbox with brackets around its value,
like in this html-code where I expect two checkboxes but get three:


   [test, prov] 

   prov 

   test 


My page has this code inside it: ("funk" are a Collection stored in the
request, "filedata" has the property "functions" that also is a Collection)


  
   
   
   


Could you please point out why I get this extra checkbox

Thanks in advance

conditional multibox validation using validwhen

[xml spy]

I am trying to use validwhen with html multibox in
struts tag.

In my JSP I am using

a) A html:multibox which renders 4 check boxes for me
(using iterate tag). 
In my ActionForm this multibox property stores values
to a "String Array" property name "reasons" 

And

b) A text field of property name "dispatch"
 - This textfield "dispatch" will have only 2 string
values 
Either “process" or "reject" (assume it gets
dynamically assigned these String values)

All I want to do is that to ensure no checkboxes are
checked when the text field dispatch=="process"

AND

All (or) at least one check box is checked when
dispatch=="reject"

I am aware of some integer comparison bug with 1.2.4
while using validwhen.

Now I am using 1.2.5 but none of my combinations seem
to work.

One of the combinations I tried is below mentioned.
This nearly works but does not ensure the checkboxes
are checked when dispatch=="reject"




test
(((dispatch == "process") and (*this* ==
null)) or ((dispatch == "reject") and (*this* !=
null)))



NOTE: for some reason when I submit these 4 checkboxes
"UNCHECKED", they seem to be *NOT* NULL. They get
initialized to a zero length array. I am not
initializing the "reasons" property in the
struts-config.xml. So this property must be
initialized to null, which happens all fine. But when
empty unchecked check boxes are submitted the
"reasons" property is no more null but a zero length
array.

I would really appreciate if someone can just reply me
with a solution.

Many thanks in advance.

Sure.  I use a String[] property in the dynamic form, and it works fine.

If you're having trouble with it, post the relevant parts of the config

RE: Help! Questions about Checkbox and multibox

[Freddy Villalba A.]

Hi t,

I'm having my own problems with checkboxes / multiboxes. However, I think I
can help u a bit with some of those questions.

- When you check a box and submit it, the value that gets submitted is the
one on the value attribute of that checkbox.

- When you check more than one checkbox with the same "name", you'll need an
array-type property for Struts handling it properly. Each position on the
array generated (setXXX-ed) by Struts will be the value of a checked box.

- I haven't actually implemented this lately, but I believe that, in case
your screen is the kind that refresh itself after the post (i.e. no post /
redirect technique being used), then you might have to reset the array on
the reset() method of the corresponding actionForm. In any case, you might
want to check Struts' web site for more info on this issue.

HTH,
Freddy-

Asunto: Help! Questions about Checkbox and multibox


Hi, all,

I have some questions regarding Checkbox and multibox:

1. What value will be returned if a checkbox is
checked? How to get it from the relevant form bean?
any example?

2. If I want to check a group of checkboxes (multibox)
after a single checkbox is checked, how to do that? I
guess javascript will be a good way, but in java
script, how to get the reference of checkbox and
multibox defined by struts ? any example?

Thanks in advance!

multibox indexed

Hello,

I have a big Problem with reading the values of the text-field in
the iterate-tag.
The Value with the ID=1 is all time wrong! and the athers are
ok.?
The Value with the index=1 is all time the value of the
initialisation and not the
changed.

My JSP:

.
 


 


" size="2"/>


 

My ActionForm:

  public LabelValueBean getLabelValue(int index){
return beans[index];
}

public void setLabels(LabelValueBean[] beans){
this.beans=beans;
   }

public void setSelDDE(String[] selDDE){
this.selDDE=selDDE;
}

public String[] getSelDDE(){
return selDDE;
}

In the ActionClass befor show the JSP I write the LabelValueBeans:

LabelValueBean[] beans=new LabelValueBean[enten.size()];
 for(int i=0;i

2004 Heini

What must I do???
Thanks
Claudia

My JSP-Code:

 





   



   


And my ActionForm:

public class MyForm extends ActionForm{

/** Creates a new instance of MyForm */
public MyForm() {
MyBean eins=new MyBean();
eins.setJahr("2002");
eins.setName("Ronja");

MyBean zwei=new MyBean();
zwei.setJahr("2003");
zwei.setName("Petra");

MyBean drei=new MyBean();
drei.setJahr("2004");
drei.setName("Heini");

init=new Object[3];

Re: Multibox/LabelValueBean Input Forms -- Paged Input

[Niall Pemberton]

The logic iterate tag has "offset" and "length" attributes which you can use
to control display subsets to a collection/array.

So if you wanted to show the second page of 10




 





If you are using jstl then then  tag has "begin" and "end"
attributes

Multibox/LabelValueBean Input Forms -- Paged Input

[chris . cranford]

I have found an example on the net where a LabelValueBean array and a string 
array are encapsulated inside a custom ActionForm object giving the user the 
ability to select checkboxed values and store the "values" behind the scene
with labeling each checkbox with the LabelValueBean's label property.

This works great for small amounts of checkbox input, such as less than 10; 
however the goal I have been tasked with is to expand on this where the data 
set is say 100 elements and each form page displays a subset of 10 items of 
the entire 100 element data set.

Once the user has traversed through all 100 items or selected those they wish, 
the form should contain an array of items that range the entire 100 element 
dataset which the user has selected.

Any thoughts, suggestions, or examples of something like this others have done 
in the past?

Multibox combined with other fields

[Guillermo Meyer]

Hi:

I have a form that may contain one or more "rows". Each row has a
passenger data. All the passengers in the form consists in a
reservation:

Number  Title   NameExtraSeat
CabinBaggage

1   Mr  Carlos Gardel   Yes(1)  No(1)
2   Mr  J.Manuel Fangio No(2)   No(2)
3   Mr  Guillermo Vilas No(3)   No(3)
4   Mr  Diego Maradona  Yes(4)  Yes(4)


ExtraSeat and CabinBaggage uses multiboxes and should be boolean values.
When I submit this form, the multiboxes that are checked are sent, but
the unchecked arent.

When posted, I receive arrays of string with:

Number={"1", "2", "3", "4"}
Title={"Mr", "Mr", "Mr", "Mr"}
Name={"Carlos Gardel", "J.Manuel Fangio", "Guillermo Vilas", "Diego
Maradona"}
ExtraSeat={"1", "4"}
CabinBaggage={"4"}

What is the usual solution for this using plain struts?
Do i should calculate the "missing" extraseat and cabinbaggage in the
reset form?
Is there any "helper" class for completing the missing non posted
checkboxes to indicate true or false in that porperties?

In fact, i should need to have this arrays in order proceed in
persisting this reservation:

Number={"1", "2", "3", "4"}
Title={"Mr", "Mr", "Mr", "Mr"}
Name={"Carlos Gardel", "J.Manuel Fangio", "Guillermo Vilas", "Diego
Maradona"}
ExtraSeat={true, false, false, true}
CabinBaggage={false, false, false, true}

Thanks in advance.

Can I use multibox with text fields?

[Miguel Arroz]

Hi!
  I need to display a page that loads a list of items from a DB, and 
that displays that list, with a text field and a checkbox per row. The 
checkbox is easy to do, using multibox. But how can I get the text 
field? Can I use something like multibox (and then read all the text 
boxes from an array), or do I have to do this manually (using iterate, 
etc)?

Re: multibox mayhem

[Irfandhy Franciscus]

from this code : 
I guess that bean1 must be an object inside 'allofem'
So why are you trying to iterate an object :

After selecting all of the checks, the user is forwarded to a

this works fine to display the selections when they are read from the

i can update the db and then read them back which works fine too.
i have confirmed that i have a HashMap with the correct Integer[]'s from

however the same code as the previous

Any ideas?  Thanks.

That makes sense.  I'm not sure why I didn't think of that.  I guess I was assuming 
the  would take care of the form submission since it was embedded in an

worked just fine:

delete

Voila!  (It's the French Open this week.)

Ricardo,
If you are going to use the html:link tag, then you
need to have it trigger a call to a JavaScript

jjust clicking the link will not submit the form.

JSTL and Multibox Submit Problem

[Ricardo Cortes]

Hi there,

I am having a problem getting the checked values from a multibox that is submitted to 
my action and I was hoping one of you could help me out.  I followed Ted Husted's 
example of using a Multibox within an iteration but I have a feeling that my setup is 
a bit different and thus renders a different solution.  I'm using a JSTL forEach loop 
to loop through a list of MessageInstance objects.  I want the user to be able to 
check which MessageInstances should be deleted and the action to perform the deletion. 
 Everything gets rendered ok but when the form is submitted, the String[] object in 
the form is empty.  I should also note that everything works fine if I use an 
html:submit but when I try to use an html:link to do the submit I don't get any 
checked values in my String[] object.  I've included some code snippets below.  Any 
help would be awesome.

Thanks!
Ricardo

JSP:
===

  Submit Link (inside ManageNotesForm):
  

   
   
   
   delete

  forEach Loop (inside ManageNotesForm):
  =

  




  

ManageNotesForm Bean:


private String[] selectedItems = {};

public String[] getSelectedItems() {
return selectedItems;
}

public void setSelectedItems(String[] selectedItems) {
this.selectedItems = selectedItems;

Multipage form and multibox fields

[Diego]

Hi everyone! I have a multi-page form with several multibox fields in its
different pages. The form is stored in session. In the ActionForm Javadoc I
found this:

--If the form is stored in session-scope so that values can be collected over
--multiple requests (a "wizard"), you must be very careful of which properties,
if
--any, are reset. As mentioned, session-scope checkboxes must be reset to false
--for any page where this property is set. This is because the client does not
--submit a checkbox value when it is clear (false). If a session-scoped
checkbox
--is not proactively reset, it can never be set to false.

Well, the problem I have is that I don't know how to do that. I mean, I know
where the reset() method is and I know how to set the multibox to false, but is
there a way to know what is the page number the user is going to? I just need to
reset the multibox fields that are on that page, if I've understood the text
above. The "page" field doesn't give me the page number I'm moving to, but the
previous one, I think.

Thanks in advance.
