RE: Checkbox not checked
From: Curtis Taylor [mailto:[EMAIL PROTECTED]
I'm not exactly sure, but I'm a tad suspect of your 'c:if
test' expression. It looks suspiciously like a Python boolean
test for the object's presence. AFAIK, in JSTL one needs to be
more explicit as to what value (or lack thereof)
when testing...
Unless, of course, it's just a typo in your email...;-)
No, that part is working fine. 'item.value.activity' is a Map of
Booleans, and I'm checking whether there's any activity for that
calendar year.
The problem is that this:
html-el:checkbox property=accounts value=${item.key}/
does not render as checked when the matching value _is_ present in the
String[] property called 'accounts' in the form bean. :(
I think it has to do with manually supplying the 'value', because it
works if you do this:
c:forEach items=${accountForm.map['accounts']} var=acct
html-el:multibox property=accounts value=${acct}/
c:out value=${accountMap[acct].costCenterDesc}/
/c:forEach
I could just hit delete now, but instead I'll archive my mistake: I
used checkbox with a String[] property. The second snippet has the
correct tag: multibox. Which is why that one works.

I have this:
c:forEach items=${accountMap} var=item
c:if
test=${item.value.activity[accountForm.map.calendarYear]}
html-el:checkbox property=accounts value=${item.key}/
c:out value=${item.key}/nbsp;
c:out value=${item.value.costCenterDesc}/
/c:if
/c:forEach
Unfortunately, the checkboxes corresponding to the String[] 'accounts'
property of the form are not being rendered as checked.
Before I go back to the Action and create a separate Map to hold only
the active accounts based on the selected year, does anyone think this
ought to work the way it is?

Re: checkbox value from getter in collection of value object
Hello Shahfazal, As i understand from the 'applicantId' getter, you want to use these checkboxes as a selecting indicator. If so, create a String[] getter/setter in your ActionForm, let say: setSelectedApplicants(String[] ids) String[] getSelectedApplicants() now in your jsp you can write: html:multibox property=selectedApplicants bean:write name=appList property=applicantid !-- this is what i get from your logic iterate, basically, you need to get applicantId from your bean -- /html:multibox this should produce HTML like input type=checkbox name=selectedApplicants value=11 input type=checkbox name=selectedApplicants value=12 now when you submit page, and inspect ActionForm.getSelectedApplicants() string array, you should get the IDs of selected checkboxes. Hope this helps!

RE: Checkbox deselect problem
Hello Michael,
We need to handle checkboxes in special way. Reset method in FormBean is

Re: checkbox condition check
Are you saying that you have a fixed set of options and depends on
what value is from your bean, the option that has the same value will
be checked?
Maybe something like this?
form
input name=checkbox type=checkbox value=val1
c:if test=${myval == 'val1'}checked/c:if
Check Box 1
/input
input type=checkbox name=checkbox2 value=val2
c:if test=${myval == 'val1'}checked/c:if
Check Box 2
/input
input type=checkbox name=checkbox3 value=val3
c:if test=${myval == 'val1'}checked/c:if
Check Box 3
/input
/form
Where myval is your the column's value you want to test for?

on each unique row.
What kind of struts tag do I use to perform the checkbox to have a
check against it or not based on whether that particular checkbox info
appears in the row because each checkbox has its respective getter
which returns boolean.
some tag to check for condition
html:checkbox property=a1

Ops the c:if's tests should be
c:if test=${myval == 'val1'}checked/c:if
c:if test=${myval == 'val2'}checked/c:if
c:if test=${myval == 'val3'}checked/c:if
or Check Box 1,2,and 3 respectively.

Subject: Checkbox and Map ActionForm
I have checkboxes on my form that have multiple options/group.
The name for each group of checkboxes is generated from the database, so
I decided to use a map on my action form to collect the checkbox values
since the names of the checkbox are not known.
However, when more than one option is selected within a group, BeanUtils
turns the array passed from the checkbox into the first value of the
array.
For example, if for box1 1,3,4 are selected, box1's value in the map is 1.
Is there a way to collect the values submitted by a checkbox group
without knowing the name of this group beforehand?
Thanks

Re: Checkbox and Map ActionForm
The array generated from selecting multiple checkboxes with the same
name is not being passed as a whole value into the action form. Instead
only the first value is being set as the value. I was wondering how you
would get the whole array into the action form.

This is probably OT, but anyway...
It may be the way you are referencing the form. Try
'document.forms[0].add.disabled = ( element.checked );'
That worked for me - I didn't use struts though - I just messed around with
static html:
html
SCRIPT LANGUAGE=JavaScript
function check(element) {
//alert(element.checked);
document.forms[0].add.disabled = ( element.checked );
}

RE: checkbox checking???
The array which are using to store values of checkboxes after form
submission; just initialize that array with the value which you wana
check.
e.g.
in form bean:
String[] array = {1}; // this is an array which will be used to store
values of the checkboxes
on jsp:
html:multibox property=array 1 /html:multibox
this checkbox will be checked when you render the page.

to an array of checkboxes with the same property.
I want the checkbox to be checked based on my
property value, it might be
differnt for checkboxes in the array.
If it is a input type=checkbox. i can
easily do it using attribute
checked, but how to do it in html:checkbox . since
struts Checkbox
does not support checked attribute.
Can anyone pls tell me.
regards
faisal

I would suggest not doing the propagate in the reset. Just use it for the original values. The values entered on the form are automatically propagated by struts after the reset by the setters and getters. Just put in some logging or print statements in those methods and you will see when they are invoked. -Original Message- From: Bjorn T Johansen [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 10, 2003 4:27 AM To: [EMAIL PROTECTED] Subject: Checkbox problem?

RE: Checkbox problem?
I had some issues with the methods, so I came up with something else that works very nicely. In the JSP, right after the code for the checkbox, use: jsp:setProperty name=beanName property=checkboxProperty value=false / This allows the form submission to work correctly, without any messy code. However, I am no expert with this stuff, so if there is any reason not to do this I'd be interested in hearing it. Keith Kamholz Programming and Architecture Moog Inc.

RE: Checkbox problem?
In your ActionForm reset() method, set the checkbox value to false. Struts will set the value to true if the box is checked. If you are using DynaForms, you will need to extend it and override the reset() method. To populate the checkbox initially, you need to instantiate and populate the form bean and place it in the appropraite context.

Generally, a good strategy is to have a prepare action and a process action. Your prepare action is where you would set your boolean form properties. You then forward to the JSP, which renders the checkboxes. The process action (from submitting the form) will determine whether the checkboxes are set or not. -Original Message- From: Bjørn T Johansen [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 10, 2003 12:38 PM To: Struts Users Mailing List Subject: Re: Checkbox problem? oki, maybe my explanation isn't the best :) (I know that I can't do it in the reset method, as it is clearly not working) but I am still not sure where to put the code to set the checkbox to true then.

I assume that you are using an Action with an ActionForm.

As to the question of boolean values that are set to false by the user: You don't have to parse the posted data manually.

The suggested method requires two actions. SetupAction - Form - ProcessAction The first action prepares any values required by your form, including setting the value of your checkboxes to true. The second action is the one that actually processes the user input gathered by the form. Hope this clarifies things.

RE: Checkbox ????
I had some issues with this method, so I came up with something else that
works very nicely.
In the JSP, right after the code for the checkbox, use:
jsp:setProperty name=beanName property=checkboxProperty value=false
/
This works very nicely, regardless of the scope that the bean is in.
However, I am no expert with this stuff, so if there is any reason not to do
this I'd be interested in hearing it.

The value is what is submitted for the checkbox if the checkbox is a checked

For example: if your form has a string property named foo, and your
checkbox's value is bob, then if you check the checkbox and submit,
form.getFoo() will return bob.
If you dont check the checkbox and submit, NOTHING is submitted (not a null,
not an empty string, nothing!) - so setFoo() is NOT called and if its value
was bob it will STAY bob. Note that if you are using a request scoped
actionForm you probably wont notice this as a problem as you will get a new
form instance each submit anyway.
Of course if you set foo to bob in your reset, then the checkbox will
display as checked, BUT if you uncheck it and submit, nothing is submitted,
so the value will still be bob in the form...
The place to preset values for your checkbox is in the action you go through
before going to the view, and your reset method should should set the value
for foo to unbob or false (if you use a boolean property) or false or
whatever so that unchecked boxes can be detected by your code.

even if its a no-op action - instead of linking directly to the jsp)

Sorry, my mistake, it is Boolean
ActionForm reset method is
((OrderEntryLineItemForm)
iterator.next()).setMarkedForRemoval(Boolean.FALSE);
jsp is

Subject: checkbox and iterate problem
Hi,
I'm having a problem with checkboxes and I was hoping someone could
help.
The short version is:
when using logic:iteratate over an array of checkboxes, the
setter
method is not called after submit
Long version
I have class CheckableString { String str; boolean checked =
false;
// etc.. };
I have a Form
HostForm extends ActionForm {
CheckableString[] mFolders = new CheckableString[100];
public CheckableString getFolder(int n) {
System.err.println(HostForm getFolder a + mFolders[n]);
return mFolders[n];
}
public CheckableString[] getFolder() {
System.err.println(HostForm getFolder b + this);
for (int i = 0; i != mFolders.length; i++) {
System.err.println(HostForm getFolder b +
mFolders[i]);
}
return mFolders;
}
public void setFolder(int n, CheckableString folders) {
System.err.println(HostForm setFolder a + folders + +
this);
mFolders[n] = folders;
}
public void setFolder(CheckableString[] folders) {
System.err.println(HostForm setFolder b + this);
mFolders = folders;
}
public void reset(ActionMapping a, HttpServletRequest b) {
System.err.println(HostForm reset + this);
flag = false;
for (int i = 0; i != mFolders.length; i++) {
System.err.println(HostForm reset
+ mFolders[i]);
if (mFolders[i] != null)
mFolders[i].setChecked(false);
}
}
}
I have an Action class setup the form, populating values from a
database,
it then forwards to a jsp page
html:form
..
logic:iterate id=quack name=hostForm property=folder
indexId=index
logic:present name='quack'
tr
th align=left
html:checkbox indexed='true' value='true' property=checked
name='quack' /
bean:write name=quack/ bean:write name=index/
/th
/tr
/logic:present
/logic:iterate
The form is populated correctly, items marked as true are selected.
And looking at the logs the getter function is called
The problem is when I submit, the setter function is NEVER called,
and the Form is not populated.
note: If I have a simple non-indexed checkbox, then that works as
expected and the setter is called
I am using struts 1.1RC1
Anyone got any ideas ??, I'm stumped
Thanks

The form is populated correctly, items marked as true are selected.
And looking at the logs the getter function is called
The problem is when I submit, the setter function is NEVER called,

RE: checkbox and iterate problem
I got it working..Thank you for your assistance.
I completely rewrote my code, and instead of using indexed=true, I
constructed the property inline using %= blah %
I'm not sure why I couldn;t get it working the first way, but now it works.
Neal
Mine is Collection, so I iterate thru the collection and set false
(String) to each checked.

I changed everything from boolean (primative) to Boolean (Object type),
no difference
I still see the same behavior.
After submit my setter function is not called.
but for a non-indexed checkbox it is called.
However the getter() is always called.

try Boolean.FALSE (Object) instead of false (which is a primitive
type).

If so, it hasn't fixed my problem.

RE: Checkbox in a multiple-page form.
Hi,
Actually you would have the same problem on pages 2, 3, etc. if there were
any checkboxes.
we had the same problem and solved it by writing separate reset functions
for each page.
In the general action forms reset method an additional property (e.g.
pageId) of the action
form controlls the execution of the correct reset function.
The value for the property (pageId) is set by the browse buttons for your
pages.
In our case we set the property in the action class extened by
LookupDispatchAction, so if we
pressed the button for Page2 the property pageId is set to page2 and only
the reset method of
page2 is executed.
Hope this helps...
Some code snippets:
/**
* From the action class extended from LookupDispatchAction
*/
protected Map getKeyMethodMap() {
Map map = new HashMap();
System.err.println(Method: getKeyMethodMap);
map.put(MyApp.Wizard.Page1.Label, page1);
map.put(MyApp.Wizard.Page2.Label, page2);
//... and many other button mappings
return map;
}
public ActionForward page1(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
System.err.println(Method: page1);
// get the form
MyActionForm f = (MyActionForm)form;
f.setPageId(page1);
return mapping.findForward(page1);
}
public ActionForward page2(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
System.err.println(Method: page2);
// get the form
MyActionForm f = (MyActionForm )form;
f.setPageId(page2);
return mapping.findForward(page2);
}
/**
* From the action form extened from ActionForm
*/
private void reset1(ActionMapping mapping, HttpServletRequest request) {
System.err.println(MyWizardForm.reset1);
// code to reset the checkboxes of page1...
}
private void reset2(ActionMapping mapping, HttpServletRequest request) {
System.err.println(MyWizardForm.reset2);
// code to reset the checkboxes...
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
System.err.println(MyWizardForm.reset (master));
// reset the checkboxes...
if (this.pageId.equals(page1)) reset1(mapping, request);
if (this.pageId.equals(page2)) reset2(mapping, request);

I have a form on 3 pages.

RE: Checkbox in a multiple-page form.
Same problem here as well. But in my case the checkbox values
are coming
from the database. So I can't set all checkbox properties to
false in the
reset() method.
Any solution in mind?
It is quite tricky.
In the reset, you must check what's the page where you clicked
the submit button.
If you clicked the Next button of page 1, then you should
reset the checkboxes of page 1.
If you come from page 2, then you should do nothing.
It works for me (I use a property in the submit buttons
, for example moveFromPage1 in the Next button of page 1,
moveFromPage2 in the Previous button of page 2).
Then I check in my reset method:
if (request.getParameter(moveFromPage1) != null) {
setCheckboxes(false);
}
So the behaviour is ok:
i click next from page 1:
i am redirected to page 2.
the reset is done:
the checkboxes are reset to false (because i
really moveFromPage1)
the checkboxes that must be checked, because of the request values,
are set to true.
or:
i click previous from page 2:
i am redirected to page 1.
the reset is done:
the checkboxes are untouched (because i don't
moveFromPage1)
there are no checkboxes that must be checked (because
there are no checkboxes values in the current request : it comes
from page 2 which has none).
Conclusion: in case 1, we reset() what the FAQ wants to reset().
in case 2, we reset() nothing.
Clear?

RE: Checkbox problem
I suppose you have several checkboxes corresponding to the List of objects. Are you using the html:multibox tag? If not, you should. The Struts framework will save the selected values in a String array that you provide. The value stored will be the value of the checkbox. For example html:multibox property=selectedItems value=foo/ if the checkbox is selected the array will include the string 'foo'. Have you looked at the html-multibox.jsp that is part of the struts-exercise-taglib application that ships with Struts?

Karr, David wrote: You might try using a more specific title line. We'd all be better off if you asked a direct question, as opposed to having us scan all of your code for anything that might be wrong. Is this code not working? If not, what is happening? Are you getting any specific error messages? Are you including the correct taglibs on your JSP page, and the correct jar files in your WAR? Note that the html:checkbox tag will only add the 'checked=checked' attribute if the value of your property is true, yes, or on (which has always bothered me somewhat, although I haven't experimented with this enough to figure out what would be a better strategy). If all else fails, it's always handy to have your debugger set up to debug your application, INCLUDING the Struts source code (associated with the release that you're using) so you can see for yourself exactly what decisions are made in the code. +1 - very handy.

RE: CheckBox and Boolean[] Array - Incorrect Values Submitted When Ch eckBox is unchecked
This is by design and you will have to write some code to accommodate it. The HTML spec mandates that no request values are passed for unchecked checkboxes, so you will have to keep track of the checkboxes yourself. What I do is type the checkboxes as String rather than boolean in the ActionForm and track true and false through the iterator.

For multiple, you also must set values back to false in reset() (The question here of course is which checkbox refers to which element. You may need to refactor such that your checkboxes return non boolean values so you can tell which is which at the server end). The reason for this is that the html spec in all its gory... uh I mean glory... has in its infinite wisdom defined that a checkbox ( radio button I think) that has not been ticked will not submit any value to the server.

RE: CheckBox and Boolean[] Array - Incorrect Values Submitted Whe n CheckBox is unchecked
I'm not sure what you mean. If a checkbox or radio button is not checked, it has NO state. This means boolean false is never passed. Only boolean trues are passed in the request object. If you are defining individual objects as boolean in your ActionForm, the JVM assigns their state to false by default, so any individual object that is passed in the request object will be true and change the state accordingly. It may look like your form is setting your ActionForm booleans to false, but it is not - the JVM is. This is why it won't work with an array - the JVM sets arrays to null by default.

RE: Checkbox in iterate
Hmmm
I'm confused, but probably just because I'm new to all this. I just started
developing web applications this summer.
There is one little trick that I came up with concerning checkboxes. I had
problems reseting the boolean values in my bean to false when the user hit
the form, so I used a jsp:setProperty .../ after the checkbox tag. This
helps the app recognize unchecked boxes nicely and saves some ugly code in
the ActionForm. I don't know that this is related to your problem at all,
but I thought I'ld mention it because other people might be having this
issue.
Sorry I'm not more help, perhaps one of the more experienced struts users
have some input.

Re: Checkbox state not changing after checked on
The underlying problem is that the HTML spec tells the browsers to not
submit a checkbox if it is not checked. (Or any other blank control for
that matter.) There's not a lot we can do about that =:o(
What happens with a box that starts out checked, is that when it is
unchecked, nothing is submitted. If the box represents a persistent
state, it just stays checked, since nothing turned it off.
Some times a radio button is a better way to go, since something will
always be submitted.
The reset method grew out of a need to set the checkboxes to a known
state, to get around this quirk of HTML.
The alternative is to scan the request for the missing checkboxes, and
set them as expected if they are missing.

RE: Checkbox state not changing after checked on
Thanks Ted.
So if I want to keep the checkbox metaphor (rather than use a radio button,
which might confuse the UI), I should use an image of a checkbox (in either
of it's states). Yes?
Is there an obvious way to derive a mapping between the Form bean and the
image on the JSP?
Thanks for your help.

Re: checkbox
Stefan, I've done something similar. My solution (which may not be ideal) was as follows: define an ArrayList property (activitiesToDelete) in the Form bean to which you are submitting this form. Then use a cell inside your iterator like this: td html:multibox property=activitiesToDelete bean:write name=aktivitaet property=aktivitaetname/ /html:multibox /td In the Action class to which you are submitting, you can then get a list of the activities you want to delete like this, String[] toDelete = request.getParameterValues(activitiesToDelete); Perhaps there's a more elegant way to do this, but when I needed to do it I didn't find one that was clearly explained in either the documentation or the mailing list. -- Rohan.

Re: Checkbox problem still not fixed :(
Hi all,
I've worked on it a bit more and come up with these
steps to make it work.
I use a multibox instead of a checkbox like this on
my form:
html:multibox name="model" property="member"
value="yes"/
I then also include with this a hidden
field
html:hidden name="model" property="member"
value="no"/
The form bean remains the same.
In my action class, I can then get the required
values by looping like this
int j =
0; for (int i = 0;
imember.length;i++)
{ if
(member[j].equals("yes"))
{ // This person is a
member so do required
events;
j+=1;
}
else// this
person is marked to not be a member
j+=1; }
This works because if the multibox was checked to
true, there will be two values for each user, a true for the multibox and then
the no from the hidden field.
If the multibox is not checked then we only get one
entry, a no from the hidden field.
To me this is a bit ineligant. Sure it works,
but...
Any other solutions?
Btw Thanks to all the people offering help on this,
it seems struts has a good community going.
Joel.

Subject: Re: Checkbox Arrays
I don't know if this is the right thread. But I just got multibox working
in my app (including preservation of checkbox entries between forwards).
Let me share with you what I have to see if this helps:
in Jsp: (cleanSolutionAreaTypes in an Application-scoped Vector)
tr
td align=left
Solutions Area*
/td
td align=left
logic:iterate id=solutionAreaType name=cleanSolutionAreaTypes
html:multibox property=solutionAreaTypes
bean:write name=solutionAreaType property=id/
/html:multibox
bean:write name=solutionAreaType property=name/br
/logic:iterate
/td
/tr
in Form:
protected String[] solutionAreaTypes = new String[0];
public String[] getSolutionAreaTypes()
{
return solutionAreaTypes;
}
public void setSolutionAreaTypes(String[] solutionAreaTypes)
{
this.solutionAreaTypes = solutionAreaTypes;
}
What was causing me some exceptions was this. I originally used another
application-scoped vector called solutionAreaTypes for other purposes
(like drop-down lists). That Vector contains an entry that has a null ID
value (eg. name = --specify-- value=). This was causing Struts to throw
a non-intuitive exception. I then created another Vector without this entry
in it and everything seems to work fine now. Of course I've only gotten it
to work about 15 minutes ago so I'll let you know later if it really works
;-)

Try pulling the bean value out into a script variable.
Taglibs cannot be nested within another taglib as an attribute.

When the form is submitted, the checkboxes that have been checked are

You can use the request.getParameterValues(checkBoxName) to retrieve

I posted this same response to your Posting Collections question yesterday.
Here it is again. If you use the html:multibox, you can get back an array
of
key values instead of an array of booleans. They key values can be Longs,
Strings, whatever, as long as it uniquely identifies the row that you want
to know was checked. If you haven't used multibox, it generates an html
checkbox. The array that will be set in your form will only contain the key
values for the rows that were checked.
Here is the post from yesterday:
I think I am doing the same thing that you want to do using the
html:multibox. When the form is submitted you get an array of the ids that
are checked and then you can go delete them.
in the jsp form (where restaurant id is a key for the item being deleted):
logic:iterate id=restaurant name=favoriterestaurants
...
html:multibox property=favoriteRestaurantRemoveList
bean:write property=restaurantId name=restaurant/
/html:multibox
...
/logic:iterate
in the form class:
private Long favoriteRestaurantRemoveList[] = new Long[0];
public Long[] getFavoriteRestaurantRemoveList() {
return (this.favoriteRestaurantRemoveList);
}
public void setFavoriteRestaurantRemoveList(Long
favoriteRestaurantRemoveList[]) {
this.favoriteRestaurantRemoveList = favoriteRestaurantRemoveList;
}
I am not sure if initializing the array to new Long[0] is necessary,
probably not.

Don't use the html:checkbox, use html:multibox and use bean:write in the
body of the tag. An html:multibox resolves to an HTML checkbox.
