[Struts 2.1.8] Has struts a problem with using own converts on nested beans?
Hi, does Struts2 has a problem using own converters on nested beans? I created a file with -conversion.properties with following content: order.orderPart.property=de.eposcat.xyz.converter.MyOwnConverter When the action is running the converter is not called (sysout for testing on both convert methods, but does not come to the console). Some testing has shown that order.property=de.eposcat.xyz.converter.MyOwnConverter is working. Can you explain this behaviour, because this from my point of view very annoying :-(.

I tried using built-in arrays (PackageBean[] and ElementBean[]) and I
get an OgnlException (source is null in setProperty( null, "property1"

I tried pre-populating my collections (List<...>) with a few empty

the way through (initializing the lists with empty beans as necessary)
with no success.
Am I way off on my thoughts of how nested beans and indexed properties
work?

Yes, reading is more intuitive than writing into the data model.
I don't know how others do this, but this is what I do.
You have the PaymentBean which has dependencies. So, in my action's
prepare() method I would instantiate those beans and wire them together.
Public class MyAction extends ActionSupport implements Preparable {
private PaymentBean paymentBean;
public void prepare () {
this.paymentBean = new PaymentBean ();
paymentBean.setDebtor (new DebtorBean () );
// Continue this pattern of instantiating and wiring.
}
...
public PaymentBean getPaymentBean() {
return this.paymentBean;
}
...
}
There might be a way of doing this using the type conversion support, but
I'm personally not familiar with it. (I use factory methods to produce my
various prototype entities, so my controller layer is not tied to a
particular domain model implementation.)
To fill in the DebtorBean.firstName property, if there was one, would be
like this in the JSP:
That will OGNL expression will get the paymentBean from your action, call
getDebtor() on the paymentBean, then call setFirstName() on the DebtorBean.

You could but it is cumbersome and error prone in my opinion.

[S2] Data entry form for nested beans
I have the following Bean, which represents an Account I am working on:
public class PaymentBean {
String acctNumber;
DebtorBean debtor; // The person who owes money(s). MAkes sense to
use this bean as I used it throughout the app
PayorBean payor; // The person making the payment(s) Same
reason as above.
CreditCardBean cc; // The card used to make the payment(s).
SinglePaymentBean[] singlePayment; // A bunch of singlePayments to
be made, with a $ amount, a fee, and a date
}
I have tried several different ways in my AccountAction to populate this
bean from the data entered on the form. I can, of course, read
multiple layers down inside my nested beans and display it in a JSP, but
how I do I allow for data entry into them?
Does one create a simple form that has a bunch of simple text fields,
and the action then uses all of these to populate the pieces of the
various beans that make up Payment Bean. Or is there a correct way to
represent this structure inside of my form so that the data goes
directly into the appropriate subBean upon form submittal? I went
through the person showcase, and thought I was on the right track, but
based upon that simple example, i was never able to get the data from
the form to the bean. Yes, I can get errors to you from the experiment
if it helps.
I could supply jsp and action code examples, but they are all just
failed tests at this point. I am so in need of direction on how best to
design and implement this base concept in Struts 2. Any, ANY, advice
and help would be greatly appreciated.

Problems with nested beans and displaying information in a dropdown box
I have a form that contains a bean with a nested collection that I'd like to
prepopulate but I'm having trouble displaying the correct information.. The
output html wiould ideally look like this:
Jon Doe
Jeff Newworth
Amy Madigan
The ActionForm contains the bean with nested beans and the error mesage I
get from Tomcat is "Cannot find bean under name customer".
My form and bean classes are defined as:
public CustomerFormBean extends ActionForm
{
CustomerBase getCustomerBase() { return customerBase; }
private CustomerBase customerBase;
}
public class CustomerBase
{
public Object[] getCustomers() { return customers.toArray(); }
private ArrayList customers;
}
public class Customer
{
public String getName() { return name; }
public String getId() { return id; }
}
My jsp code looks like this:
Could some one point me toward the right direction in helping me understand
what's wrong here?

Nested Beans and Validation
Hello, I have been using struts for a bit now, and I am trying to see if the following situation is possible. In a merchant checkout situation, I would like to be able to create a bean that has nested beans inside. Eg: This will be a shopping cart checkout, and I have the need for an overall bean to keep track of which section they are on, as well as creating "Billing" and "Shipping" beans nested inside this bean. I know from a programmatic side that this is possible, but the problem begins with validation and form presentation. Each page currently has a bean associated with the action, and on the receiving page I use the html:text, etc. tags, and I always have to make sure the proprties are in the bean. But when dealing with a bean with a nested bean I do not know how to call the html:element? And if I have one bean associated with many actions, and I have different validator.DynaValidatorForm objects, how do I validate nested beans? In a overall scenario, I would like to be able to create one large bean associated with many actions and have the ability to use the html:elements and do validation all within the one large bean, validating and using nested bean elements? I have googled around, but do not see anyways to accomplish this short of a wizard approach, which I am trying to avoid. Thanks, Scott

Nested Beans
Hello Everyone,
I've got an easy one, that is stupifying me because of my tiredness.
I've got a POJO with a List in it. The List is a list of beans. In my
JSP page I'm trying to iterate over the list of beans. Here goes:
public class Information {
private String name = null;
private String addr = null;
private List School = null;
School is a bean that looks like:
public class School {
private String schoolname = null;
private String location = null;
}
Then I set that information in the session:
session.setAttribute("information", information);
Each information bean will have a list of schools in it and I'd like to
iterate over that list on the JSP page but I'm not sure how far I am
from the truth! :-P Right now I've got:
RE: Validating DynaBean nested beans with a custom validator.
Sorry for the outrageoulsy long-winded question. It really boiled down
to this: how to get the PersonFormBean off the Object bean generically.
The answer is to use PropertyUtils.getSimpleProperty(...).
(BeanUtils.getProperty returns a String.)

Validating DynaBean nested beans with a custom validator.
Dear All,
I have a DynaValidatorActionForm like this:
When the related form is submitted the action adds the 'newPerson' to
the 'personList' and replaces newPerson, on the DynaBean, with a new
PersonFormBean. This all works fine. Now I want to add declarative
validation for the newPerson, so only valid newPersons reach the action
code that adds them to the list.
The thing is that PersonFormBeans (in this example) have a start and end
date (a period). The validation rules for these fields are:
* start date and end date must be dates (dd/MM/)
* start date must be before end date
* end date must be after or equal to today
* etc...
So, you see, apart from the first rule, this goes beyond what can be
achieved by plucking out the fields from the nested bean and using the
default set of simple field validators shipped with struts (required,
date etc.). (Even if you disagree that these validation requirements
cannot be met in using the default validators please read on. This is
just an example.)
I have created a new validator that I want to handle the entire nested
PersonFormBean: personValidator.
public static boolean validatePerson(Object bean, ValidatorAction va,
Field field, ActionErrors errors, HttpServletRequest request)
{
PersonFormBean personFormBean =
somehowGetTheBloodyPersonFormBeanOffTheBean(bean);
// Do the validation directly on the personFormBean.
return true;
}
private static PersonFormBean
somehowGetTheBloodyPersonFormBeanOffTheBean(Object bean)
{
// How do I implement this?
// It has to be generic, in case I change my mind about the type of
the bean,
// e.g. make it a simple bean with getters and setters instead of
using the DynaBean...
return null;
}
Would you:
a) grab the nested PersonFormBean from the main, parent bean and then
work directly with this? If so how? Is there a utility method somewhere?
b) grab individual fields from the nested bean using BeanUtils methods
(or other - feel free to advise).
Your thoughts/urls would be appreciated.
Many thanks.

Re: Struts Validator and Nested Beans
The Validator plug in can recognize fields names such as "employee.name", and that's the extent of my experience with it. Nested forms/tags allow you to go much deeper than that, and everytime I do, I choose to use my own validate() implementation instead of using Validator.

Struts Validator and Nested Beans
I've not been able to find any examples so I was hoping someone may have tried this before. I am making copious use of nesting on my forms and I was wondering if this will prevent me from using the Struts validation framework? --dlm - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Properties of Nested Beans
I have narrowed the behaviour down somewhat - it appears to be related
to using capital letters in properties.
If I change the name of the LocationID String in the LocationBean from
locationID to LocationID I get the following error:
[ServletException in:/WEB-INF/jsp/admin/location/locselect.jsp] No
getter method for property LocationID of bean result'
javax.servlet.jsp.JspException: No getter method for property
LocationID of bean result at

Re: Properties of Nested Beans
Try keyboardmonkey.com It has good stuff on nested tags which is what probably need. -Yves- On Fri, 08 Oct 2004 11:39:27 -0400, Bill Siggelkow <[EMAIL PROTECTED]> wrote: > There is no such restriction -- please provide some code so we can help > diagnose your problem. > > -Bill Siggelkow > > > > Chris Stavrianou wrote: > > HI all, > > > > I am having a problem with collections of beans nested within beans. > > > > I have found that I can only nested beans and get property names if > > the property names are unique across the entire application. > > > > Is this a usual quirk of the way Struts uses reflection? > > > > Are there restrictions on reusing names through form beans and other > > beans across the scope of a web-application? > > > > Thanks > > > > C.S. > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > -- For me to poop on! http://www.formetopoopon.com http://www.nbc.com/nbc/Late_Night_with_Conan_O'Brien/video/triumph.shtml - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Properties of Nested Beans
There is no such restriction -- please provide some code so we can help diagnose your problem. -Bill Siggelkow Chris Stavrianou wrote: HI all, I am having a problem with collections of beans nested within beans.

Properties of Nested Beans
HI all, I am having a problem with collections of beans nested within beans. I have found that I can only nested beans and get property names if the property names are unique across the entire application. Is this a usual quirk of the way Struts uses reflection? Are there restrictions on reusing names through form beans and other beans across the scope of a web-application?

nested beans and validation?
Hi I have a subclass of DynaValidatorForm with nested Forms, some in a list others just singular This works ok however I want to sort the validation out. After searching the list the only solution I have found is to add each nested form's validation to the top level form in the validation.xml using dot notation. This works fine but each time I want to reuse a nested form I have to duplicate the validation rules Ideas ? Thanks Simon
