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.

I use checkboxes to input some variables in a form and as long as I
insert new records, i.e. the checkbox variable gets set to false in the
form's reset method, it works fine.
But when I, say, edit the same record (and propagate the values of the
form in the reset method), I never can uncheck the checkbox if it was
set to true in the reset method.

Are there any solutions/work around for this?

[Kamholz, Keith (corp-staff) USX]

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:


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.

RE: Checkbox problem?

[Bjørn T Johansen]

Yes, but to clarify...
I am showing a jsp page with values read from a database. If the
checkbox value is true, how do I then make the checkbox on my jsp-page
checked and how do I then find out if the checkbox has been unchecked?
Do I have to manually read the posted data and see if the checkbox
attribute is missing or is there a better way?

RE: Checkbox problem?

[Kevin Robair]

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. For more details, see:

http://jakarta.apache.org/struts/faqs/newbie.html#prepopulate
http://jakarta.apache.org/struts/faqs/newbie.html#checkbox

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

To make the value of the checkbox come up correctly, import
struts tags into your jsp-page: 

<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="strb" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="strh" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="strl" %>

Then use the Struts checkbox tag:



Assuming that your form has the methods getDone and setDone,
these methods will be used to render the value of the checkbox
correctly.

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
method reset() in ActionForm is run before the posted data is
used to populate the form.  Write your own reset() method where
you set the boolean fields to false.

Re: Checkbox problem?

You are missing my point! If I just could set the checkbox value to
false in the reset method, everything is fine. But there are times when
that value has to be reset to true and not false and if I do that in my
reset method, I am not able to see of the user unchek the checkbox,
because the boolean variable is still true after the form has been
posted!

No, actually *YOU* are missing the point!  Several people have tried to 
explain how this works to you.

So, for one last effort


DO *NOT* SET THE FIELDS YOU INTENT TO USE AS CHECKBOXES (booleans) TO TRUE IN 
THE RESET METHOD!  


If you want the field to be true when the page is rendered, set it to true 
from your action class, NOT in the reset of your formbean.

I hope that clears it up for you.

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.
As far as I know, the action class isn't called before after the form
bean has called the reset method and the page has been rendered (and the
submit button has been pressed), or is it something I am missing?

You can pre-populate the form in a previous action. Here is an example.

RE: Checkbox problem?

[Karr, David]

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.

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.

Not necessarily two Actions... I use LookupDispatchAction with a request
parameter to control which method should be called.

RE: Checkbox problem

[Sri Sankaran]

I suppose you have several checkboxes corresponding to the List of objects.

Are you using the  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



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?

In my form bean I have an attribute which is an Arraylist of  objects who in turn 
contain many attributes one of which is a string representing 
a checkbox of my screen.

Problem :

-When I check anyof the check boxes and proceed to the next screens and 
comeback again to the screen having the check boxes to uncheck 
  some of the checkboxes which I have checked earlier then it's not getting 
updated in the form bean.
 I have taken the default value of the attribute representing the checkbox as 
false. And when it gets checked I'm making it to True.

So any solution?

I use a html:checkbox for setting a boolean value. But after submit, the

Do I have to use a String value for that in my form bean? I tried this, but

Thanks for your comment, but I'm not sure if that's the problem.

Here is the scenario:
1.) While populating the form, the value is true. 
2.) Then the user disables the checkbox - for setting the value to false.
3.) Submit occurs.
4.) In the action I check the value and I see that it is true.

RE: CheckBox problem in struts..

[Alex Paransky]

The reset(...) method in your form needs to reset the checkbox to "false",
every time.

Re: Checkbox problem still not fixed :(

Hi! 
I had a similar problem and solved it by changing 
the attribute scope in my 
action in the struts-config.xml file to request 
instead of session.

  :(
  
  Hi everyone.
   
  I've tried just about everything in the mail 
  archive but can't get check/multi boxes to perform how I want to.
  I use an iterate tag over a collection, basically 
  on my jsp page I have as follows
   
  
  blah  blah  
  
   
  In my form bean I have an array pk[] and another 
  member[].
  In the reset method I do:
  for(int i = 
0;i
      member[i] = 
  "false";
   
  When I check the values off the form in my action 
  class, i still only get the values set to true. I need a long list, true, 
  false, true, true etc for all the values.
   
  Sorry to be a pain but can someone give me some 
  sort of 'exact' steps to solve the problem? I haven't been able to piece 
  together all the help on the mail archive.
   
  Thanks,
  Joel

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:
 

 
I then also include with this a hidden 
field
 

 
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; 
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.
