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:
logic:iterate indexId=counter name=interestFrom id=item
property=items
html:multibox property=selectedItems 
bean:write name=item /
/html:multibox
bean:message key=interests.bean:write name=item / /
/logic:iterate


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 input type=checkbox... field instead of
html:multibox

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.

I am not explicitly calling the reset anywhere.
I've also debugged it and can not find anything out of the ordinary.
From I can tell it is the request processor that is resetting my form
prior to the page displaying that ends up with the checkboxes not
checked.

Any help?

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.

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

A couple of things to check
1. Is your get action using the same form as your post action?
2. Do the names of the checkboxes in the html match your form?
3. Where are you resetting the checkboxes? I'm hoping you're doing it
by overriding ActionForm.reset().

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

[Garner Shawn]

I reset my checkboxes and a multibox in a form reset method but then
when I come back to the page the values arn't checked.
If I don't reset them then it won't register them as not checked anymore.

How do I fix this?

I'm not sure I understand the question, but it sounds like you're not 
iterating your second list. You're probably missing an index expression. 
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.

logic:iterate id=apprEntry name=listDevApprGrpList indexId=userIndex
html:multibox property=toBeAddedList 
   bean:write name=apprEntry property=userID/
   /html:multibox/td
/logic:iterate

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(bean:write name=apprEntry property=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()
{
 for(var i=0; idocument.forms[0].toBeAddedList.length; i++)
 {
   document.forms[0].toBeAddedList[i].checked = true;
 }
}


I guess that would have been bad example if you already knew that you could
set multibox and retireve them.

In your logic, i guess in your actionForm you can prepare the string array
based on the logic.

you display the values from the database.
the user makes a selection and submits the form,
you compare that in the action form from the database and then preapre the
string array and the appropriate checkboxes are checked.

I hope that helps.

Thanks
Uday Karrothi

 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:
 html:multibox property=valuesvalue1/html:multibox 1
 html:multibox property=valuesvalue2/html:multibox 2
 html:multibox property=valuesvalue3/html:multibox 3
 html:multibox property=valuesvalue4/html:multibox 4
 html:multibox property=valuesvalue5/html:multibox 5

 3. HTML sent to browser looks like this:
 input type=checkbox name=values value=value1 checked 1
 input type=checkbox name=values value=value1 2
 input type=checkbox name=values value=value1 checked 3
 input type=checkbox name=values value=value1 4
 input type=checkbox name=values value=value1 checked 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?

I dont' have such a sequence like that, but you can get the same when
you read the source code of the RequestProcessor class.

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.

You sure you aren't missing the /html:multibox ? Double check your typing.



Btw: the property deaktserver resolves to a
get/setDeaktserver() which gets or sets an ArrayList String.


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, 
though, but try changing it to String[] just to see.)

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 bean:write name=srv / 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 String.

How do I insert a value from an id-iterate-bean into the value-tag of multibox?

[Andreas Hartmann]

Hello!

I've got in a jsp the following code:

logic:iterate name=Portal property=deaktserver id=srv
html:multibox property=inaktmachines value='%= srv %' /
/logic:iterate

- This does not work.


srv contains a string which I want to have as value of html:multibox. How
should it be written?


I would be glad to get a hint!

scrollbar vs multibox

[Eric Plante]

hi,

I have a div on autoscroll that contains multibox. Here's the code

div id=motUrlLst class=motLst
  logic:iterate id=mot name=PandoraForm property=motTreeMap
  nbsp;
  html:multibox property=motSelectLst style=width: 10px;height: 
10px onclick=autoPostBack('motSelectLst;' + this.value);

 bean:write name=mot property=key/
  /html:multibox
 span class=mot onclick='remplirChampsMot(bean:write 
name=mot property=key/)'

 bean:write name=mot property=value filter=false/
 /spanbr/
  /logic:iterate
/div

It works fine when the vertical scroll bar is needed but instead of applying 
the  horizontal, the text change line which is annoying.


Any idea how the problem could be solved?

Thanks

This is nothing to do with Struts, it's just how the HTML render model 
works. I'm sure there are other solutions, but the two I'd look at to 
start would be setting nowrap or minwidth on the div in its CSS rules.

/html:multibox

This is one of the many ways I've tried to get it to work:
html:multibox property=selectedModules property=${row.id}

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:
c:forEach items=${accountMap} var=item 
  html-el:multibox property=accounts value=${item.key}/
  c:out value=${item.key}/ c:out 
value=${item.value.costCenterDesc}/
/c:forEach

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: Multibox

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 html:multibox .../ is 
invoked on the page, it will recongize the relationship and render the 
checkboxes as checked.

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: 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

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

 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).

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

[Radu Badita]

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,
Mike

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).

multibox with label value beans

[Shey Rab Pawo]

I do a dropdown list as follows with a list holding label value beans:

  html:select property=entries size='1'
html:options collection=entries_list
  property=value
  labelProperty=label /
  /html:select

How would I put these into a mulit-checkbox?  Thanks for any assistance.

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

sent to the action?

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++) {
%
input type=checkbox name=value%=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:

input type=checkbox name=value%=i% 
%=af.getIsChecked(i)=true?checked:

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:

struts-html:multibox property=subscriptions
struts-bean:write name=_bean property=code//struts-html:multibox
 struts-bean:write name=_bean property=description/br
/struts-logic:iterate
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

[Wendy Smoak]

From: Kedar Deshpande [EMAIL PROTECTED]
 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
 'value' value so that i know which ones are checked when the form is
 sent to the action?

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.

   c:forEach items=${accountMap} var=item 
   html-el:multibox property=accounts value=${item.key}/
   c:out value=${item.key}/ br/
/c:forEach

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.

Fair enough.  But, now you are tied  pretty securely to Struts.  I'm not 
saying that's a bad thing or even a concern to most, but it is something 
to be aware of.

We all strive for separation and low-coupling of everything these days, 
and rightly so, and to me that also means the ability to change 
frameworks without touching my presentation layer (within some necessary 
constraints of course)

You make perfectly valid points though, so throw it all into the hopper 
and make a decision Kedar! :)

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++) {
%
input type=checkbox name=value%=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:

input type=checkbox name=value%=i% 
%=af.getIsChecked(i)=true?checked:

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:
struts-html:multibox property=subscriptions
struts-bean:write name=_bean property=code//struts-html:multibox
 struts-bean:write name=_bean property=description/br
/struts-logic:iterate
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.

Could someone please post an example of using a 'for loop'

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

Re: creating a for loop structure for multibox

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).

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.

David

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

RE: Multibox DynaActionForm

[Robert Taylor]

You will need to set the selectedCompanies in the ActionForm
so that the html:multibox .../ 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.

RE: Multibox DynaActionForm

Ah.. stupid me =)

So the solution with dynaactionform is:
---
public ActionForward execute(ActionMapping _mapping, ActionForm _form,
HttpServletRequest _request, HttpServletResponse _response) throws
Exception 

{

DynaActionForm dynaForm = (DynaActionForm) _form;

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

String[] companies = MyDBTools.getUser(userId).getCompanies();
ArrayList allCompanies = MyDBTools.getAllCompanies();
 
dynaForm.set(selectedCompanies, companies);
_request.setAttribute(allCompanies, allCompanies );

return _mapping.findForward(continue);
}

use disabled instead of readonly.

Subject: Multibox deselection problem

Hi !

I have a problem with the Multibox behaviour. I have checked the online doc
but nothing helped me so far... Here is my problem :

My app workflow is :
prepareImportAction.do  -  Import.jsp  -  processImportAction.do

In the prepareImportAction.do, I initialize the entities var (of type
String[], in session scope), so that the checkboxes are checked by default
when the jsp page is displayed :
String[] defaultEntities = {A, B, C, D};
myform.set(entities, defaultEntities);

In the jsp page, I have a set of :
html:multibox property=entities value=A/
html:multibox property=entities value=B/
html:multibox property=entities value=C/
html:multibox property=entities value=D/

I also have a small javascript that allows the user to select or deselect
all checkboxes in one click :
function checkAll(field)
{   var i;
for (i=0;ifield.length;i++)
{   field[i].checked=true;   }
}
(nearly the same for de-selecting all checkboxes)

Now here is my problem. When I de-select all the checkboxes in my jsp page,
by hand or by javascript, my processImport.do receives a String[] array
containing the entities that were defined in preparaImport.do as default,
instead of an empty array.
This only happens only when all entities are deselected : if a single one is
selected, I get the desired behaviour.

May you help me to understand where I am wrong and why it doesn't work
please?

SV: Multibox problem

[Roland Carlsson]

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.

Regards
Roland Carlsson

 How many items are in the func data structure in request scope?
 This is what drives the number of iterations.

 Subject: Multibox problem
 
 
 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:
 
 input type=checkbox name=functions value=[test, prov]
[test, prov] 
 input type=checkbox name=functions value=prov checked=checked
prov 
 input type=checkbox name=functions value=test checked=checked
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)
 
 logic:iterate id=item name=func scope=request
   html:multibox name=filedata property=functions
bean:write name=item/
   /html:multibox
bean:write name=item/
 /logic:iterate
 
 Could you please point out why I get this extra checkbox
 
 Thanks in advance
 Roland Carlsson
 
 
 ps: I have looked in the arcives but it says it doesn't support textsearch

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) atleast one check box is checked when
dispatch==reject

I am aware of some integer comparison bug with 1.2.4
while using validwhen.
now 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
field property=reasons
indexedListProperty=reasons depends=validwhen
page=1 
arg key=error.reasons.input position=0 /
var
var-nametest/var-name
var-value(((dispatch == process) and (*this* ==
null)) or ((dispatch == reject) and (*this* !=
null)))/var-value
/var
/field
 
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.

DynaValidatorForm and multibox

I'm using struts 1.1
Is it possible to use a multibox with a DynaValidatorForm?  

Are there any documented examples?  I searched the archives...no mention of it.

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
files and JSP and someone will take a look.

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

[Claudia Woestheinrich]

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:
html:form action=/ProjektDDE.do
.
 logic:iterate id=ente name=projektForm property=enten
indexId=ID

tr
td class=tl1html:multibox property=selDDE value=
%=ID.toString()%/html:multiboxnbsp;bean:write name=ente
property=dde//td
td class=tl1bean:write name=ente property=name//td
td class=tl1bean:write name=ente property
=beschreibung//td
td class=tl1html:text property=%=labelValue[
+ID+].label% size=2//td
/tr

 /logic:iterate

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;ienten.size() ;i++){
   LabelValueBean bean=new LabelValueBean(3,new
Integer(i).toString());
   beans[i]=bean;
  }
  form.setLabels(beans);

After call ProjektDDE.do I read the selDDE and the LabelValueBean.

The values in selDDE from the checkbox are ok, but the value from
the LabelValueBean-Array
are for the index=1 not correct! (Only for the index=1, the others
are ok. The Label for the
index = i is all time the initialvalue (in this case 3)).

Whats wrong?

Thanks Claudia

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

logic:iterate id=myLabelBeans
 name=myForm
 property=myLabelBeans
 offset=10
 length=10

html:checkbox name=myLabelBeans property=myValue indexed=true
 bean:write name=myLabelBeans property=myLabel/
/html:checkbox

/logic:iterate


If you are using jstl then then c:forEach tag has begin and end
attributes

c:forEach var=myLabelBeans
 items=$(myForm.myLabelBeans}
 begin=10
 end=19

html:checkbox name=myLabelBeans property=myValue indexed=true
 bean:write name=myLabelBeans property=myLabel/
/html:checkbox

/c:forEach

Subject: Multibox/LabelValueBean Input Forms -- Paged Input


 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.

multibox mayhem

[pls]

I have one multibox per page on a few pages.
Each page name is represented by the 'key' property of a HashMap.
Each selected checkbox number is stored in Integer[]'s in the 'value'
property of a HashMap.

After selecting all of the checks, the user is forwarded to a
confirmation.jsp which displays the selections.
the code: (i removed table formatting for clarity)

logic:iterate id=bean1 name=multiBoxForm property=allofem
   bean:write name=bean1 property=key/
   logic:iterate id=bean2 name=bean1 property=value
  bean:write name=bean2 /
   /logic:iterate
/logic:iterate

this works fine to display the selections when they are read from the
original ActionForm.
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 the
db inside,

however the same code as the previous
is located in profile.jsp and it returns the following JasperException:
Cannot find bean bean2 in any scope

Any ideas?  Thanks.

Re: multibox mayhem

[Irfandhy Franciscus]

from this code : bean:write name=bean1 property=key/
I guess that bean1 must be an object inside 'allofem'
So why are you trying to iterate an object :
logic:iterate id=bean2 name=bean1 property=value

confirmation.jsp which displays the selections.
the code: (i removed table formatting for clarity)
logic:iterate id=bean1 name=multiBoxForm property=allofem
  bean:write name=bean1 property=key/
  logic:iterate id=bean2 name=bean1 property=value
 bean:write name=bean2 /
  /logic:iterate
/logic:iterate
this works fine to display the selections when they are read from the
original ActionForm.
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
the
db inside,
however the same code as the previous
is located in profile.jsp and it returns the following JasperException:
Cannot find bean bean2 in any scope
Any ideas?  Thanks.

Hello Miguel,

You might want to search the archive for indexed properties; I think

Subject: Can I use multibox with text fields?


 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)?

Yours

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

Ricardo,
If you are going to use the html:link tag, then you
need to have it trigger a call to a JavaScript
function that will submit the form for you. Otherwise,
jjust clicking the link will not submit the form.

Richard

RE: JSTL and Multibox Submit Problem (SOLVED)

[Ricardo Cortes]

That makes sense.  I'm not sure why I didn't think of that.  I guess I was assuming 
the html:link would take care of the form submission since it was embedded in an 
html:form.  So, I've added an onclick attribute to my html:link as follows and it 
worked just fine:

html:link onclick=document.forms[0].submit(); href=# 
name=deleteNotesLinkdelete/html:link

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

Thanks Richard.

multibox not resetting

[Mathieu Grimault]

 Hello !

Multibox made me crazy !! After having each problem detailled on the mailing
list i've got another not detailled...

I've got a jsp page with a multibox inside an iterate. the initial display
is correct and i can correctly retrieve the selected or unselected values
and, then write to the database some infos. The problem is when i come back
to the multibox page, the display doesn't take care of what has been changed
! Even if i call the reset method... Datas used by the reset method are
correct but it seems that the multiboxes are not been replaced. The only
solution i found is having a new session... where are placed the multibox ??
the form is request scoped...

I've noticed that reset is called at the first generation of the form and
when i leave the page but even if a forced it after i'm sure that it use
correct datas, it doesn't work.

The display is generated via the form's reset method with session scoped
datas written in page1 (see below).

how can i forcing the use of a totally new form ? Any solution ?

Best regards, mathieu.

scenario :

page1(request on the database) --- page2 (with the multibox and writing to
the database) --- page3 (confirmation and a link t page1)

Here are the problem :
struts-config.xml : -
action path = /UnitesEnseignements
type = UnitesEnseignementsAction
name = UnitesEnseignementsForm
scope = request
validate = false
input = /jsp/unitesEnseignements.jsp


jsp : -
logic:iterate name=unitesEnseignements scope=session
id=uniteEnseignement
tr
td
html:multibox property=valeurs
bean:write name=uniteEnseignement property=temoinSession2/
/html:multibox
/td
tdbean:write name=uniteEnseignement property=libelle//td
/tr
/logic:iterate

form : -

public void reset(ActionMapping mapping, HttpServletRequest request) {
HttpSession session = request.getSession();
ArrayList unitesEnseignements =
(ArrayList)session.getAttribute(unitesEnseignements);
valeurs = new String[unitesEnseignements.size()];
for(int i=0;iunitesEnseignements.size();i++) {
HashMap ligne = (HashMap)unitesEnseignements.get(i);

if (((String)ligne.get(temoinSession2)).equals(O))
valeurs[i] = (String)ligne.get(code);
}

for (int i=0;ivaleurs.length;i++)
System.out.println(valeurs[i]);
}
}

[50% SOLVED] Resetting Multibox problems

[Mathieu Grimault]

I've found a way of bypassing the problem by using a logic:equal and
logic:notEqual inside the jsp and testing my row value. This way, the
display is correct... it's just not clean.


New jsp :

logic:equal name=uniteEnseignement property=temoinSession2 value=O
input type=checkbox name=valeurs value=bean:write
name=uniteEnseignement property=code/ checked=checked
/logic:equal
logic:notEqual name=uniteEnseignement property=temoinSession2
value=O
input type=checkbox name=valeurs value=bean:write
name=uniteEnseignement property=code/
/logic:notEqual

Old jsp :

html:multibox property=valeurs
bean:write name=uniteEnseignement property=temoinSession2/
/html:multibox

Subject: Resetting Multibox problems


Re-Hello !

In addition to my question, i've seen that spy the reset() and constructor
call of my actionForm :

life cylcle :
- constructor - first access on the jsp
- reset - first access on the jsp
- display of the jsp and submit
- constructor - after submiting
- reset - after submiting
- the form is transmitted to an action who forward to another jsp

Each time i came back to the jsp :
- reset - each time a leave the jsp

As i mention before, i used combo box. They are correctly initalised the
first time but never changed whatever the reset method does (normally) and
whatever is set in the String[]...

Regards.

You really shouldn't need to do all that.  Here's a working example of
multibox from my project.  In my case 'accountMap' is not a form
property, it's a Map sitting in session scope.  I'm not sure if the code
you posted is wrapped in a logic:iterate or not?  Stuts will
pre-select the correct checkboxes based on the values in the String[]
form property.

In the JSP
c:forEach items=${accountMap} var=item 
   html-el:multibox property=accounts value=${item.key}/ 
   c:out value=${item.key}/ br/
/c:forEach

The Form property is a String[]:
 form-bean
name=accountForm
type=edu.asu.vpia.struts.AccountForm
   form-property 
 name=accounts  
 type=java.lang.String[]/
 /form-bean  

And the reset method, which only resets if the form is actually being
submitted:
public void reset( ActionMapping mapping, HttpServletRequest request )
   {
  log.debug( reset: begin );
  if ( request.getMethod().equals( POST ) ) {
 log.debug( reset: request was POSTed, resetting );
 set( accounts, new String[]{} );
 set( includeDetail, Boolean.FALSE );
  }
   }

I put this on my Wiki because it comes up often:  
http://wiki.wendysmoak.com/cgi-bin/wiki.pl?StrutsMultiBox

If anyone has suggestions, just edit the page...

Hope that helps!
