Checkbox problem
Hi Group, I am using Struts 1.1 version. I have a page in which i display a set of checkboxes(10 checkboxes to be specific). All the checkboxes have the same name and have different values. I have an ActionForm for this. In the ActionForm, i have a String[] checkBoxArr to represent these checkboxes. I have a condition that i have to check one particular checkbox out of the ten. Some said to set this in the constructor. Please suggest a way for doing this. Many Thanks, Janarthan S - Do you Yahoo!? Yahoo! SiteBuilder - Free web site building tool. Try it!

Oki, thanks for all your suggestions; I'll try them out and see what happens... :) BTJ On Tue, 2003-06-10 at 22:11, Steve Raeburn wrote: The suggested method requires two actions.

Checkbox problem?
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.

Antwort: Checkbox problem?
The reset-method is called if you are submitting from a jsp-page. You must check the browser request, if a value exists. If a value is missing, the user has unchecked the box, so you can set the record to false.

RE: Checkbox problem?
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.

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?
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.

You are missing my point! If I just could set the checkbox value to false in the reset method, everything is fine.

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 %

strh:checkbox property=done/
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

used to populate the form. Write your own reset() method where
you set the boolean fields to false.

RE: Checkbox problem?
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.

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.

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?

Re: multibox, checkbox PROBLEM FOUND, SOLUTION NOT!!!
Ok suppose to have a Form with a checkbox named isOn and a submit
button name Save
a NOT checked value will produce:
http://localhost:8080/webappointments/openChk.do?action=Save
a checked value will produce:
http://localhost:8080/webappointments/openChk.do?isOn=onaction=Save
The problem is that if I have a checked value that I want to turn off
I'll send
http://localhost:8080/webappointments/openChk.do?action=Save
the form function
public void setIsOn( boolean isOn )
{
this.isOn = isOn;
}
is not called and the value will not be changed.
Where am I wrong ??

RE: multibox, checkbox PROBLEM FOUND, SOLUTION NOT!!!
I'm coming into this discussion late, so ignore me if I'm out in left field, but it sounds like you're unhappy that when *no* checkboxes are checked, *no* methods get called. When you submit the form, only successful form elements are sent in the request, so if *no* checkboxes are checked, *nothing* related to those checkboxes will be present in the request. Isn't this what the reset method is all about? The reset method will be called before Struts automagically populates all of your ActionForm fields. I can't tell what your Collection is from this post, but try clearing out *all* of the values in the Collection that handles your checkboxes in the reset() method of the Form. Then, if you uncheck all of the boxes and submit, you should see that none of them are checked when the form is redisplayed (or you use the data). Hope that helps, -- Wendy Smoak Arizona State University PA IRM
Re: multibox, checkbox PROBLEM FOUND, SOLUTION NOT!!!
Thanks a lot , you have been very clarifying.
I've found a tip placing code in validate method :
public ActionErrors validate( ActionMapping mapping, HttpServletRequest
req) {
String str = req.getParameter( isOn );
if (str == null)
isOn = false;
return null;
}
But it's a very dirty technique of course.

Kiuma wrote: I've found a tip placing code in validate method : But it's a very dirty technique of course. That will work, but... what if you have a form that you don't want to validate? The reason this is working is that you have validate set to true so that the validate method gets called. If you set validate to false, it'll stop working. One line in your reset method will do the same thing: isOn = false; The reset method will autmatically get called before the set-methods for the successful form elements. So if the checkbox isn't checked, the isOn property will remain false. If it is checked, then the setIsOn method will be called and isOn will be set to true. For the sake of the person who has to maintain your code later on, (not to mention your own sanity when you look at this in six months,) use the validate and reset methods for their intended purposes. :) -- Wendy Smoak Arizona State University IA IRM

Checkbox problem still not fixed :(
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 form blah hidden name="pk" blah checkbox property="member" /form In my form bean I have an array pk[] and another member[]. In the reset method I do: for(int i = 0;imember.length;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 [EMAIL PROTECTED]
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. /Linnéa - Original Message - From: Joel Vogt To: [EMAIL PROTECTED] Sent: Thursday, June 28, 2001 10:04 AM Subject: Checkbox problem still not fixed :( Hi everyone.

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.
