YES YOU R RIGHT. WHEN THE CHECK BOX IS NOT CHECKED, THE FORM WILL NOT EVEN
HAVE THAT ELEMENT PRESENT. THIS IS AN ERROR IN STRUTS. IN OUR APPLICATION WE
WROTE A CODE WHICH CHECK FOR THIS ELEMENT AN IT IS IS NOT THERE THEN MADE IT
"FALSE"

Thanks for the response, but I don't think the problem lies with the actual
validation that's happening.
I suspect that when a user submits the form page without a checkbox/radio
button checked, a blank variable is never sent to the form bean (i.e
http://www.url.com/servlet.do?checkboxvar=), it just doesn't send anything.
The form bean then sees it as as a nonexistent variable and returns a trace
stack error. Any other ideas?
I will however update my struts package.

Did you file a Bugzilla bug report ? If not could you file a Bugilla
report, attaching a detailed description and/or
test case is the best way to get this fixed.

RE: Struts form validation of radio buttons and checkboxes
As Hill said it is not the issue with the struts but with the HTML. SO i don't think
it has to do anything with the version of struts you are using.
type is boolean ( primitive).. not Boolean.

RE: Struts form validation of radio buttons and checkboxes
don't understand why I want to reset the checkboxes to their unticked value. Im in a hurry to get home (taxi fare doubles after midnight!) so dont have time to explain in detail, but if you check the javadocs for the reset() method and search the mail list archive you should be able to find the info you need :-) (This question is a regular one!) Mind you, if your form is request scoped it would implicitly be 'reset' as you are getting a new form instance each time. Hmm. Have you perchance set the default value for the checkbox to be ticked or is this a session scoped form? -Original Message- From: Greg Amaroso [mailto:[EMAIL PROTECTED] Sent: Thursday, 4 September 2003 23:03 To: Struts Users Mailing List Subject: Re: Struts form validation of radio buttons and checkboxes No, I haven't implemented it yet.

RE: Struts form validation of radio buttons and checkboxes
Have you implemented code in reset() to reset the checkbox to its unticked
value in the form yet?
Not sure why radio buttons would give you problems though.
They usually have one option selected which would get submitted.

RE: Struts form validation of radio buttons and checkboxes
OI!
STOP ALL THAT SHOUTING!
ITS GIVING ME A HEADACHE.
(I know your terminal can do lower case - I can see it in your sample code!)
And while Ive got your attention, it is *not* "AN ERROR IN STRUTS" that the
checkbox is not submitted, it is a result of the html specifications (whose
writers probably came up with the idea after a few too many beers and
thought it would be a "bit of a laugh").
Browsers simply dont submit *anything* for an unticked checkbox and there
isnt anything that struts can do about it apart from provide a workaround in
the form of the reset() method. (Well actually I can think of one other
thing it could do but it involves JS and hidden fields and I rather doubt
the committers would approve.)
If you had bothered to read the javadoc for the reset() method of the
ActionForm class you would know this:
http://jakarta.apache.org/struts/api/index.html ">
Reset all bean properties to their default state. This method is called
before the properties are repopulated by the controller servlet. The default
implementation does nothing. Subclasses should override this method to reset
all bean properties to default values. This method is not the appropriate
place to initialize form values for an "update" type page (this should be
done in a setup Action). You mainly need to worry about setting checkbox
values to false; most of the time you can leave this method unimplemented
(Note the bit about checkboxes)

YES YOU R RIGHT. WHEN THE CHECK BOX IS NOT CHECKED, THE FORM WILL NOT EVEN
HAVE THAT ELEMENT PRESENT. THIS IS AN ERROR IN STRUTS. IN OUR APPLICATION WE
WROTE A CODE WHICH CHECK FOR THIS ELEMENT AN IT IS IS NOT THERE THEN MADE IT
"FALSE"
ALSO MAKE SURE YOU HAVE isCheckbox():return boolean instead if
getCheckbox():return String in your action form.

Thanks for the response, but I don't think the problem lies with the actual
validation that's happening.
I suspect that when a user submits the form page without a checkbox/radio
button checked, a blank variable is never sent to the form bean (i.e
http://www.url.com/servlet.do?checkboxvar=), it just doesn't send anything.
The form bean then sees it as as a nonexistent variable and returns a trace
stack error. Any other ideas?
I will however update my struts package.

Try a --nightly-- build of struts. I believe it has enhancements in
commons-validator to validate
radio controls. you can tell for sure by looking at the validator-rules.xml.
In there you'll see itels like :
function validateRequired(form) {
//Stuff deleted.
if (field.type == 'text' ||
//stuff deleted
field.type == 'radio' ||
field.type == 'password') {
So this says that for the 'required' rule radio is supported.
Do the same for integer, byte, etc to see if 'radio' is supported.
In the struts-config.xml file, should the form-property type be set to
java.lang.String or java.lang.Boolean?
In the page with the form, does it look right to create the radio buttons
like this:
Are there any other tricks to doing this that differs from validating
standard text boxes, textareas, etc.?
Thank in advance.
