RE: ClassCastException coming from DynaValidatorForm.validate()-> bug or a feature?

[Steve Armstrong]

Hi,

Validator has support for validating multi-page forms via the use of an
optional "page" attribute, associated with a field element, that can be set
to an integer.  From the Validator portion of the user guide:

All validation for any field on a page less than or equal to the current
page is performed server side. All validation for any field on a page equal
to the current page is generated for the client side Javascript. A
multi-part form expects the page attribute to be set



Since your form already defines a page property, and a non-integer one at
that, I can see how things might get screwed up.

Cheers,
-Steve

I went to the source to try to find out what was causing this problem, and I
started to suspect that:



was the problem... sure enough, when I changed the name to "thePage",
instead of "page", it worked.

Would this be a bug or just a feature that I missed the documentation for?

Subject: Validator Framework & Value Object ActionForm


Hi all,

I have the following action form:

/*
 * Created on Nov 19, 2003
 *
 * To change the template for this generated file go to
 * Window - Preferences - Java - Code Generation - Code and Comments
 */
package nl.informatiefabriek.addressbook.form;

import nl.informatiefabriek.addressbook.value.ContactValue;

import org.apache.struts.action.ActionForm;

/**
 * @author harm
 *
 * @struts.form name = "contactForm"
 */
public class ContactForm extends ActionForm {
private ContactValue contactValue = new ContactValue();

/**
 * @return Returns the contactValue.
 */
public ContactValue getContactValue() {
return contactValue;
}

/**
 * @param contactValue The contactValue to set.
 */
public void setContactValue(ContactValue contactValue) {
this.contactValue = contactValue;
}

}

As you can see my Action Form only stores a ValueObject (Data Transfer
Object) which is send to the EJB tier in my application.
My ValueObject contains a property 'email'.:


 public java.lang.String getEmail()
   {
  return this.email;
   }

   public void setEmail( java.lang.String email )
   {
  this.email = email;
  emailHasBeenSet = true;

   }


I would like to use the Validator Framework to validate the emailaddress
stored in the ValueObject.

I'm not sure on how to do this, because the email property is stored in
the Value Object and not in the ActionForm object.

Can somebody provide me a hint on how to validate this using the Validator
Framework?

Thanks,

RE: html_image property value not submitted

[Steve Armstrong]

The "value" attribute of an HTML 'input type="image"' tag (i.e., what the
Struts  tag is generating) is apparently ignored by all (most?)
browsers.  See:

http://www.blooberry.com/indexdot/html/tagpages/i/inputimage.htm

One solution is to have a hidden variable in your HTML form associated with
your form bean (let's use the bean property name "action") and then use
JavaScript to set this property appropriately on submit.  Something like,





In the action associated with your form, you can then consult the "action"

RE: Bean tag help

[Steve Armstrong]

Howdy,

There are a number of things that are incorrect in your example:

1. Concerning your definition:



You can set the value of your scripting variable "processName" from a bean,
a property of a bean, or a "hard-coded" value.  I believe you are trying to
set your scripting variable from the "processName" property of a bean named
"filesForm" (i.e., filesForm.getProcessName()).  However, you also specify a
value attribute which probably overrides this (I'd have to look at the
source code for the tag to see how it is actually resolving this ambiguity)
which would set your scripting variable "processName" to the String
"filesForm".  This is probably not what you want.

2.  I believe that as soon as you use the value attribute, the scripting
variable will automatically be set to java.lang.String and your value for
the type attribute is promptly ignored.  Once again, I'd have to look at the
source for the tag to be 100% sure.  Anyway, you have to set the type
attribute correctly if you're getting the value from a bean or the property
of a bean, otherwise the type is java.lang.Object by default.  So, if your
getter for processName returns a String, specify that the type of the define
is java.lang.String.

3. There is no need to create a scripting variable as above to be able to do
.  This is saying that you want to
create an HTML form input tag of type hidden with the value of the named
property associated with the form bean that is associated with your action.
I assume that "filesForm" is the bean associated with your action, and it
has a property named "processName".  If this is a request scope form bean,
and the value of "processName" isn't editable (i.e., it isn't used in a text
field on your form), and you want its original value to be set in your form
bean when the form is submitted, then the html:hidden tag is all you need.
Your bean:define is trying to set a scripting variable with the same name
(and value) as your form bean property and has nothing to do with the task
you're trying to accomplish (I believe).

Cheers,
-Steve

<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

RE: Bean tag help

[Steve Armstrong]

I really don't know how to explain things any more clearly.  I suggest you
buy a Struts book, and check out the documentation for the tag libraries on
the Struts web site.  Your bean:define tags make absolutely no sense.
Please read the following:

http://jakarta.apache.org/struts/userGuide/struts-bean.html#define

In particular:

The corresponding value to which this new attribute (and scripting variable)
is set are specified via use of exactly *one* of the following approaches
(trying to use more than one will result in a JspException being thrown):

Specify a name attribute (plus optional property and scope attributes) - The
created attribute and scripting variable will be of the type of the
retrieved JavaBean property, unless it is a Java primitive type, in which
case it will be wrapped in the appropriate wrapper class (i.e. int is
wrapped by java.lang.Integer).

Specify a value attribute - The created attribute and scripting variable
will be of type java.lang.String, set to the value of this attribute.

Specify nested body content - The created attribute and scripting variable
will be of type java.lang.String, set to the value of the nested body
content.

--

Your bean:define tags are performing both 1 and 2 and hence, according to
the doc, a JspException should be thrown.  As I also mentioned, they seem to
make no semantic sense for the context you provided in your e-mail.  Why are
you creating scripting variables via bean:define?  What is the purpose of
this step?

RE: how to pass a jsp variable to a javascript function

[Steve Armstrong]

Howdy,

There are definitely a number of funky things in your code example.  I'm not
exactly sure what you're trying to do since your onchange attribute is
calling a JavaScript function called "projectChange" which I don't see
anywhere, but here are a couple of things to look out for:

1.  I don't believe you can use a JSP expression inside some JavaScript
code, but someone can certainly correct me if I'm wrong.  What I have done
in the past is use a  tag, so you should be able to do something
like:




  var y = ;


if you *really* want to do that.

2. However, your question was "how do I pass a JSP variable to a Javascript
function" and it looks like this is what you are attempting to do with the
next part of your code:



For this to work correctly, your JSP expression needs to be the entire value
for the onchange attribute (i.e., you can't embed a JSP expression into the
middle of an attribute value).  Thus, assuming you have a JavaScript
function named "projectChange" defined, and you really want to pass in a
JavaScript variable to this function as opposed to say, the Integer value
itself, then you should be able to say something like:



3. But, rather than setting a JavaScript variable inside a nested:iterate
and then trying to pass this variable into "projectChange" it would seem to
be much simpler to simply pass in the value itself.  In other words,
something like:


  

I haven't tested the above, but if I haven't missed any syntactic sugar, it
should work.

Cheers,
-Steve

One way that I have considered doing this is with simple resource keys, viz:

validation rule in my action form's validate method, that disallows users
from selecting more options than permitted by my limit. if a user goes over
the limit the form doesn't get submitted. the validation rule is checked
just fine; struts creates an error for it and adds it to the errors
collection. but the error message that is displayed on the input page does
not contain the parameterized message as expected. instead, it shows the
complete, unformatted message, exactly (minus an apostrophe) as it appears
in the resource bundle! does anybody know what i'm overlooking? is this a
bug in 1.0.2?

here is what gets displayed (verbatim) on the input page after the
validation error is created:

  Sorry! Youve selected too many choices for {0}.  (what happened to my
apostrophe in "You've" ?)

here is the appropriate line from my resource bundle:

  error.prefs.limit=Sorry! You've selected too many choices for {0}.

here is a snip from my form's validate method:
  ...
  ActionErrors errors = new ActionErrors();
  ...
  if ( isTooManyPrefs ) {
 ActionError prefMusicError = new ActionError( "error.prefs.limit",
"Preferred Music" );
  errors.add( "prefMusic", prefMusicError );

   }
  ...

here are the results of me looping through prefMusicError.getValues() inside
validate:

  error.prefs.limit's replacement value # 0: Preferred Music
  error.prefs.limit's replacement value # 1: null
  error.prefs.limit's replacement value # 2: null
  error.prefs.limit's replacement value # 3: null


here is a snip from the input page that generates the validation error and
to which struts reports the error:

  ...
   
  ...

what's going on here? why doesn't struts format the message to include the
replacement value. it's obviously there! at least *i* can get at it from the
object array that i get from ActionError.getValues()! please, help! thanks
in advance.

RE: nested:iterate and indexId problems

[Steve Armstrong]

Thanks very much for the speedy response!

When I said that  worked, I had an "id" attribute in that
particular scenario so perhaps that's why everything was okie-dokie.
Another work around I found was to do the following:

subsitute:




with:





One more intermediate step, but no biggie.  As to why it works, I'll leave
that mystery up to you bright fellows :-)

Cheers,

Just had a play, and there's a bug in the tag's extra info class around
the indexId.
Until then, set an "id" attribute also, and it should work.

Seems though the extension is troubled by its super class, and it's
looking like a fix is required there also. Either way, I'll sort it out
tonight (few hours from now), so you can download NeXt again tomorrow,
and it'll be sweet. Actually, from looking at the code, it's a surprise
that common  tags aren't suffering from the same issue.

nested:iterate and indexId problems

[Steve Armstrong]

Hi,

I'm using Struts 1.0.2 with the NeXt package targeted for that particular
load.  I'm having a problem evaluating the page scope Integer bean that
should be created via the indexId attribute.

Inside an , I have something like the following for handling odd
and even rows of a table differently:











The above is from memory so please excuse any minor syntax errors.  When the
 line is processed, an error is generated indicating that
"loop" (our page scope Integer bean set by the nested:iterate tag) is not a
valid variable.  However, if I replace  with plain
 everything works fine.

Am I running into some sort of scoping issue when I use ?

Any help would be much appreciated.

Thanks,
-Steve

RE: BeanUtil BUG (this is actually correct behaviour)

[Steve Armstrong]

Fernando Esteban Barril Otero [mailto:[EMAIL PROTECTED]] writes:

I think that is the normal behavior for JavaBean properties.
When you have a setter/getter for a property starting with
more than one upper char, the property name must have exactly
the same name (without the "normal" convention).

Correct.  The following is from the JavaBeans spec:

8.8 Capitalization of inferred names

When we use design patterns to infer a property name, we need to decide what
rules
to follow for capitalizing the inferred name. If we extract the name from
the middle of a normal mixedCase style Java name then the name will, by
default, begin with a capital letter.

Java programmers are accustomed to having normal identifiers start with
lower case letters.
Vigorous reviewer input has convinced us that we should follow this same
conventional rule
for property names.

Thus when we extract a property name from the middle of an existing Java
name, we normally
convert the first character to lower case. However to support the occasional
use of all upper-case names, we check if the first two characters of the
name are both upper case and if so leave it alone. So for example,

"FooBah" becomes "fooBah"
"Z" becomes "z"
"URL" becomes "URL"
