I don't know where you got the idea that JSF does not need a layer like Action Classes. This layer is where your UI logic will go - it's the layer that converts the incoming request parameters into an object that your backend/business layer can understand. It's true that you won't be required to extend a base action class, but make no mistake, you'll still have these objects. The only way you can avoid this layer is if you use a framework that allowed web requests to directly call your business logic object and pass fully populated business domain objects. I've experimented with one just for fun but if I were to ever use it in an actual app, I'd still have an "action" object layer for web-specific logic (redirection, view preparation, etc). One way to find out what JSF won't provide, or needs improvement on, in a bullet-list format, would be to take a look at what they've listed for the next major version. Read Section 2 of JSF 314 [1].

Re: Form submission
There are differences in how a user interacts with html:button and
html:submit. For instance, pressing enter on some fields can trigger
a submit button, but not a regular button. You can get the best of
both worlds letting your javascript method determine whether the
submit should happen at all but still letting your submit button
actually submit the form:
function populateAndSubmit() {
if (goAheadCondition) {
// don't call document.ChallengeQuestionForm.submit() here
// let the submit button do the submit
return true;
} else {
// tell the submit button not to proceed
return false;
}

Re: DynaValidatorForm with java.util.Date
The fields of action forms, including DynaValidatorForms are populated
from request parameters, and these values are all in String variables.
I suggest using a String variable for the dyna validator form field
as well, and just parsing it to get the java.util.Date equivalent when
you use it in your Action classes.

Subject: DynaValidatorForm with java.util.Date
Hi
I have a form in which a Date is displayed, using fmt. It's static text, so no
user input is required. The problem is the following. When the validation of
that form fails, you return to that form. Actually, it should return to that
form, but you're redirected to the error page.
This is the error:
2448020 12 03 09:29 [http-8080-Processor24] ERROR
org.apache.struts.util.RequestUtils - javax.servlet.ServletException:
BeanUtils.populate
javax.servlet.ServletException: BeanUtils.populate
The form bean exists of a field, which is hidden, of the type java.util.Date.
This is filled by the action, with the correct date. When I look at the source
of the page, the date is actually filled in, so that's not the problem.
I assume there's a problem with assigning the java.util.Date-type to a field in
a DynaValidatorForm, but I'm not sure that's what causing the problem. There's
also no validation on that field.
Struts-config:
Does anybody know how to have a Date-field in your form, in a way you can
assign it to a textfield and make sure you can also pass it to fmt:formatDate.

If you consult the documentation for the reset() method [1], you'll
see it's mainly for resetting checkbox values:
"This method is not the appropriate place to initialize form value 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

I have a page that is populated using indexed properties. The prepopulation

have and what I am trying to do:
The following is what I am working with :
JSP:
What I am trying to achieve is that a user clicks on a link, they are sent
to page, and all of the values are prepopulated. The page is then displayed
and the user has the option to modify any of the variables that they want to
before resubmitting the page. (When they resubmit the form has a url
parameter attached to it). What is happening (or at least what I believe is

the variables, page is displayed, user can modify the page and resubmit,
reset is called on the form, the action is called (this is where it dies as
there is no longer an ArrayList) to modify. My question is am I going about
this in a manner that seems sensible or am I way off base ? I have the
values being prepopulated, but when trying to use the values that the user
puts in I can't use them in the action, nor can I pull the values from the
form without again setting the values in the form. I am hoping it is that
I have over looked something, but it's possible that I don't understand
something as well.
Here is the Action code (This is the entire execute method) :
HttpSession session = request.getSession();
ProdSelectionForm prodSelection = (ProdSelectionForm) form;
User user ;
user = (User)session.getAttribute("User");
Order order = new Order();
ArrayList products = new ArrayList();
ArrayList pageRes = new ArrayList();
ArrayList results = new ArrayList();
String action = (request.getParameter("Dest") == null ? "populate" :
request.getParameter("Dest") );
order = user.getCurrOrder(user);
if(action.equals("populate"))
{
prodSelection.setResults(order.getProducts());
}
if(action.equals("Delete"))
{
ArrayList p = new ArrayList();

Products is an object that stores various things about a product with
numProducts, and description being two of those things.
Within Products is both getter and setter methods for the numProducts as
well as description.

Re: Nested form beans
So what does happen when you submit the form? Are you getting NPEs?
By the time Struts attempts to populate the form bean, the nested
forms should already be instantiated. You should have getters and
setters for af1 and af2, and getAf1() and getAf2() should not return a
null. This could be an issue if the form bean is new, either because
it's in request scope, or in session scope but was not previously
instantiated.

I'm facing a situation where ideally I'd like to have a single ActionForm
like so:
public class MyActionForm extends ActionForm {
AnotherActionForm1 af1;

When in my JSP I do:
...I do indeed see the value as I expect. The way I did this is to have
an Action mapping that references MyActionForm, then within the Action I
instantiate AnotherActionForm1, set the value of field1 on it, and then
set af1 to that new AnotherActionForm1 instance. That all works nicely.
Here's where I run into a problem...
On the page I basically have 2 separate HTML forms, one for
AnotherActionForm1 and another for AnotherActionForm2. However, I have a
SINGLE submit button at the end (just plain button that makes an AJAX
request). onClick of that button, I create a query string from the values
of both forms, and make a request to the server with the query string
attached. The parameter names of the query string arguments are
af1.field1 and af2.field2, mimicing what's in MyActionForm. The mapping
that the request goes to again references MyActionForm.
What I've been told should happen is that Struts should be able to
instantiate those two nested beans and set the properties, since the
parameter names give it the information it needs. This does not however
seem to be happening.
So, two questions... first, is that in fact the expected behavoir? And
two, if so, any ideas what I'm doing wrong? I can post all the pertinent
config and code, but thought it might be something more generic that
wouldn't require all that. This is the first time I've ever had a need to
nest forms like this, so it's a new question for me.
Thanks all!

In your example Address is nested within ActionForm, right?
No. What happens is an ActionForm is nested within an ActionForm.
((DynaBean) form).get("address") will return another DynaBean.
What if I
have an object like Person having Address as its member. All
properties are strongly-typed so I do not want to expose them for I/O,
instead I want to have autogenerated ActionForm fields so that I could
redisplay them on error. Say I do not nest Persion inside ActionForm.
Can I still somehow have a string property inside my ActionForm that
corresponds to Person.Address? Can this property be autogenerated?
This is how FormDef works. Of course, you'll have to tell FormDef
about the address form, but that's very easy:
FormUtils.getFormValues() and setFormValues() takes care of handling
the nested objects, instantiating them as needed.
As you can imagine, they can go multiple levels, all nesting
Stringified versions of your business objects. In one of my sample
apps, I have a "companyForm" with an "addressForm" and a collection of
"employeeForm" objects, with each employee having its own
"addressForm" nested form.

Subject: Re: FormDef
Um, by nested beans I mean a bean which is a property of ActionForm
like Employee, not a bean which is a property of a bean which is a
property of an ActionForm, like Address. I guess there is a
discrepancy in terminology here ;-)
What I mean is this (taken from
http://www.rabago.net/struts/formdef/manual.htm):
"To declare a form bean using FormDef, simple add a entry in
the configuration file, provide the name for your form bean, and the
name of the class from which the form bean will be patterned after.
... When the plugin gets executed, it will create a DynaActionForm
containing String fields for each property of MyBean.
To me MyBean is nested within a DynaActionForm. If this is not a
proper term, what do you call it? Calling it just a property will do a
disservice (I think so) because it is not a primitive type.
Actually, with FormDef, it will be a primitive type (err, String, actually).
What FormDef generates is a String field for each field of MyBean.
Okay, let's make sure we're talking about the same thing.
If I were to just use struts-config.xml to define my forms, here's two
ways I can do it.
Here's a non-nested approach (Approach 1):
BeanUtils.copyProperties(myForm, myBean);
Here's my interpretation of a nested approach (Approach 2):
myBean = ((DynaActionForm) myForm).get("myBean");
FormDef use Approach 1.
So when converters and validators are executed? Is it correct that
when I call FormUtils.setFormValues() then output converter is
executed (uh, do you have output converters?), and when I call
FormUtils.getFormValues() then input converters and validators are
executed? Validation or conversion is not executed automatically or at
least can be turned off?
Yes, there are output converters. Validation would typically be
through Commons Validator (like most dyna forms). Conversion happens
based on convention but can be configured by the user.

Hey Michael,
Just thought I'd set the record straight.
FormDef does not require nor enforce nested beans.
public class Employee {
public String getName() { return name; }
public void setName(String name) { this.name = name; }
public Date getHireDate() { return hireDate; }
public void setHireDate(Date hireDate) { this.hireDate = hireDate; }

You're still using traditional ActionForms, and you still need to copy
to and from the form bean and business object (using BeanUtils or
FormDef's own methods).
So, your form still looks the same way:
FormDef support nested beans, and nested collections of beans. If you
had a nested Address object, your form would look like:

Re: ActionForm Use It to Populate JSP fields?
That's how I do it most of the time. If your POJO is in session scope, your Action won't even have to do anything. I usually only use ActionForm when there's a corresponding HTML . If I'm just displaying data on the page, I just pass the POJO.

Do you mean something like ActionRedirect?

It still won't allow you to redirect to a tile, though.

Re: Where dose JSP works in JSF request lifecycle?
On 4/28/06, Craig McClanahan <[EMAIL PROTECTED]> wrote: Sorry for not being clearer. You can indeed register a listener with a declaration -- you get an application wide singleton that has the same lifetime as your application. However, it's also possible to add a phase listener programmatically, by getinng access to the Lifecycle instance (from the LifecycleFactory), and calling addPhaseListener() on it -- the standard JavaBeans event listener registration pattern. You might, for example, want to create a request scope backing bean that registers itself for phase listener events just for the duration of this request (you still have to disambiguate whether the event is for "your" request or not -- easiest way to do that is to compare the FacesContext instance included in the event to the one that was active when your backing bean was created). If you do this, but don't remember to deregister at the end of the request -- and you need to be robust in case exceptions were thrown -- then the list of phase listeners will get longer and longer. And, because there are live references to them in the Lifecycle instance, they would never be garbage collected either. In the very first version of Creator, we were experimenting with request scoped phase listeners like this, and found it easier to use the single instance approach instead. Shale's design benefits from that experience as well. Craig Ok, thanks for the clarification! Hubert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The way to do this would be to define a phase listener for Render Response phase, and do your data collection in the beforePhase event handler. You also have to remember that your listener is going to receive beforePhase() calls for *all* simultaneously active requests, not just the one page you might be interested in. And, don't forget to deregister yourself as a listener when the request completes, so you don't create a memory leak. Craig, What do you mean deregister the listener? Where is the leak from? My understanding was I register the the PhaseListener in faces-config, and the listener is active for the entire life of my application.

The viewId is changed in ViewHandlerImpl.renderView(). The problem is that TilesViewHandler doesn't call this method if it identifies the view as a Tile. The view gets saved as "/view.jsf" because ViewHandlerImpl never got a chance to update the view id. On postback, it's like I described above. The view isn't restored because it's looking for the wrong view id. Unless someone tells me otherwise, I'll file this as a bug.

[shale] Tiles integration with RI
I'm trying to use Shale-Tiles with RI and I'm having trouble submitting forms. The page renders okay (once I start using all over the place), but the submit doesn't work. I stepped through the code and it looks like there's a viewid mismatch. Here's my tile definition: I request /myapp/testing.jsf which renders ok. I type in a value in a text field and submit the form. In the RI's ViewHandlerImpl.restoreView(), it's looking for viewid="/testing.jsp", but the viewid recorded in the sessionMap is "/testing.jsf", so the submit request gets treated as a new one instead of a postback.

Re: [1.2.x] Struts 1.2.x on latest Commons releases?
The primary motivation for the recent 1.2.x releases were security issues [1] [2]. Because of this, the goal was to minimize possible upgrade issues, so the changes were limited to security fixes. The upgrade notes on the wiki for 1.2.8 and 1.2.9 [3] mentions that the user may wish to upgrade JCV as well. However, that upgrade is not required to get the security fixes.

throws ServletException {
String actionList = "";

for(int i = 0; i < actionConfigurations.length; i++) {
actionList += actionConfigurations[i].getPath();
}
servlet.getServletContext().setAttribute("actionList", actionList);
}
public void destroy() {
// does nothing
}
}

Re: formbean of double type value chages when submitting the form
I'm not sure what you mean by "I am validating the DynaValidatorForm properties to check is the user is entering the right value, ..., which is wrong" but I'm gonna try responding anyway and see if I interpreted you correctly. The validation happens after Struts has populated the form bean but before the Action is called. The idea is that the action will never be called unless you agree that the form's contents are valid and that your action object can handle it. What this means in the context of BeanUtils.copyProperties() is that the String value held by the form property is a value that can be properly converted into a Double (in this case). So Validator well say "0.0" is valid, "120.00" is valid, "1a3" is invalid (cannot be converted to a double). hth, Hubert On 3/24/06, fea jabi <[EMAIL PROTECTED]> wrote: > BeanUtils.copyProperties(myBusinessBean,form)) is copying DynaValidatorForm > String values to the myBusinessBean which is having the right data types. > > But in validator.xml, I am validating the DynaValidatorForm properties to > check if user is entering the right value i.e Double. which is wrong. > > I think I am missing something here. > > Please, explain. thanks. > > > > >From: "Hubert Rabago" <[EMAIL PROTECTED]> > >Reply-To: "Struts Users Mailing List" > >To: "Struts Users Mailing List" > >Subject: Re: formbean of double type value chages when submitting the form > >Date: Fri, 24 Mar 2006 08:49:50 -0600 > > > >On 3/24/06, fea jabi <[EMAIL PROTECTED]> wrote: > > > thankyou for your response and clear expaination. > > > > > > If I use String for the formbean do I have to convert it to Double > >before i > > > validate? > > > > > > Is there an easier way to convert all form-properties in the form at the > > > same time? > > > >Yes.

Re: formbean of double type value chages when submitting the form
You know, you're right. I don't know why we list those there since DynaActionForm can support any type. (pause, think.) Hmm, maybe next week I'll find time to fix that. (Patches to docs are welcome!) Anyway, I think you missed a statement a few paragraphs down the same section: "And, of course, while the DynaActionForm may support various binary types, properties used with the html:text tag should still be String properties." Going back on topic, you can use whatever type you need in DynaActionForm as long as you know what you're doing and you can handle the consequences. Laurie's option 1 is an example of handling it yourself, although now that I think about it, I think FormPropertyConfig is the one that replaces the null with "new Double()" which is where you get your "0.0". Ahh, I'll have to look again to see how you can intercept this. So, bottom line, yes, you can put whatever type in Dyna*Form fields you want. I sometimes put other Dyna*Form objects in them. If you do, though, you'll have to know how to handle them yourself. The default form handle only handles Strings and booleans.

Re: ActionForm Patterns? Nested Javabeans as ActionForm properties
The FormDef version that has built-in support for nested beans actually requires Struts 1.2.7 or higher. I'm not aware of a "concise document" that covers what you're asking. However, there are upgrade notes you can check for upgrading from 1.1 to 1.2.4, then from 1.2.4 to 1.2.7 [1]. There's not a whole lot involved in the 1.2.4 to 1.2.7 step, mostly just using the new jars, TLD, and validation XML files. You can also look at the release notes for 1.2.4 [2] and 1.2.7 [3] to get an idea of what's changed between versions.

Re: ActionForm with ArrayList and logic:iterate .... confusing problem ...
Hans, You're using request scope for your form. When Struts processes the submitted form, it will create a new instance of your ActionForm. The question now is, is the new instance ready to deal with setting values on your ArrayList field? Struts will not instantiate that list for you, it wouldn't know how to. So make sure that when Struts accesses your ActionForm, the ArrayList already exists.

Hence, the null pointer exception. This is your problem right here. You request /addCamper which validate='true'. Because of this, Struts will always call validate(), and so calls to your getters will be made. Since your getters rely on camper, and camper is null, you'll get NPE's each time. The quickest way to fix this would be make sure camper is always available before your getters are called. The better way to fix this would be to use a different action that doesn't require validation if you don't have data to validate.

Or is there any other solution ?? http://www.keyboardmonkey.com/next/index.jsp has tutorials that cover this. I personally wouldn't do it any other way. As for the beans themselves... if you don't have form beans for these objects yet, take a look at FormDef. It can handle the form bean generation, form population, and bean population for you [1]. There's a sample app that shows using a bean that nests a collection of beans that nests another bean [2]. Otherwise, take a look at using commons-collection's lazyList [3]. I think you can also use the LazyValidatorForm [4] for this. Search the user list archives on more about using lazy list and the lazy validator form [5].

Re: Need some advice
You should name the fields in a way that allows Struts (BeanUtils, actually) to get to the correct property, such as "address.street". Also, make sure your accessor for the nested bean always returns a non-null bean, or else you'll get an NPE when the form is submitted.

[ANN] FormDef 1.0 Release
I've always told people I'll start [ANN]ouncing once I hit 1.0, so... FormDef 1.0 has been released and is ready for download. http://www.rabago.net/struts/formdef/ FormDef allows you to easily declare Struts form beans based on existing business classes. This allows an application to reuse property information and keep business classes and form beans in sync. FormDef works with all types of dynamic ActionForms, and FormDef-defined forms can be used like normally-defined form beans. But that is just the beginning. FormDef also has the following features: * Data formatting support to allow html form controls to use formatted text * Conversion methods to format and parse data between your form and business object * Support for beans that nest other beans, or a collection of other beans * Locale support to allow the same form to be used in different locales using different formats * Extensions to allow both form definitions and form validations to reside in one XML More information is available on http://www.rabago.net/struts/formdef/ including downloads, manual, sample applications. Source CVS is hosted by java.net on https://formdef.dev.java.net/. For what's new in this release, and a link to the release notes, please see https://formdef.dev.java.net/servlets/ReadMsg?list=users&msgNo=229 Thanks to all those who've contributed code, patches, ideas, bug reports! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

If all the config files are for the same module, make sure you put the request processor definition in just one of those config files.

Re: Set values in form bean
If there's a form associated with a request, Struts automatically populates the form bean for you. Just submit the form to a URL with a proper form bean mapping, and struts will populate the form bean with values from request parameters for parameters whose names match those on the form. It doesn't matter if the form you're submitting is hidden or not, or if there isn't even an actual HTML form. Even a GET /myPage.do?id=001 request, if mapped to an action mapping with an associated form, will have its form populated for you by Struts.

Re: Validation Issue
This is what's happening:
1) User submit form with invalid data to /Control.do
2) Struts finds action mapping for /Control.do and sees validate="true"
3) Struts call's the form's validate()
4) validate returns false
5) Since validation fails, Struts forwards to the "input" url
6) Go to step 2
There are several possible solutions:
1) Use a different action class to handle the invalid form, set its
mapping to validate="false"
2) Set validate="false" on /Control and validate manually
3) Use the same action class but different URL mappings
("/ControlInvalid",validate="false")
If you want to investigate (2) but you don't know how, check out
Rick's tutorial on http://www.learntechnology.net/validate-manually.do

Re: Is struts handling informations differently between post and get?
Struts won't change the value of request parameters. I'm certainly no encoding expert, but if you want to narrow down the cause, try playing with a basic servlet and see what it gets from request parameters.

Re: Displaying Images from database using Struts tags
You'd have to write an Action which reads the image from the DB and writes it onto the servlet's output stream. There was a thread just yesterday which discussed how to do this. You can set your image URL to that action and provide it with enough parameters to find your image in the DB.

Re: How to use a POJO inside Struts FormBean?
You'll need to rename your "iDef" property if that is what you're
calling it, via getIDef/setIDef. That pair will result in a property
name of "IDef". If you'd rather not change your accessor methods,
then use "IDef.partNumber" instead of "iDef.partNumber". [Wendy can
quote the JavaBean spec related to this :)]
Also, if you still get some error when the form is submitted, that may
mean you're putting the bean in request scope and the IDef property is
null and is not available during form bean population. Make sure
getIDef() always returns a non-null result.

You should not limit applications in one platform only to what another platform provides. This is like saying colored TV programs should not worry about how the colors look because radio programs don't even provide images. They are different mediums, different platforms, with different characteristics. Each will have different capabilities, and being able to go to a specific page is a basic an ability of web applications. Besides, I may not expect to launch Open Office in a precise dialog box, but if I know I want to open a specific document in open office, I want the ability to double click on that document and have it open right away. I don't want to go through several windows and dialog boxes to search for something I already have in my sight. Just because you're using a framework that makes it harder to support what should be basic functionality provided by the environment you're in, doesn't make supporting it a bad idea. Earlier Struts versions made it hard to do redirects with parameters. The solution is not to spread a gospel that said "redirects with parameters are bad", the solution is to provide support for it in the framework.

And if you guessed "formdef" you'd be correct. Here's how the "address", "employee", and "company" forms were defined in the sample app I have: To summarize, it says "create addressForm and give it the same fields as my Address object", "create employeeForm and give it the same fields as my Employee object, plus a 'selectedButton' field. Oh, and use the 'addressForm' definition for the 'address' field", and the same essentially for the "companyForm", except I defined "employees" to be a list, and told the converter which form to map its elements to, and which Collection implementation class to use.

Re: The Age-Old problem of validation when you have Nested Items- opinions and Dyna question
I've always used String values. Given that difference, I've seen this work: datePatternStrict MM/dd/ In this case, the form bean has a collection of "employees", and each employee has a "birth" field. Then something like beside the field will show which of the many employees has the invalid date. I have a sample app (minus the tag, though I've just tried that and it works) somewhere you can download it if you want to see it. That sample app actually goes one level deeper: Each "employee" has an address field which is also a nested form, with zip as an int field.

Re: How would you solve this problem?
Sorry for coming in late to the discussion but I only read this thread now.
I may have misunderstood the problem. I'm thinking the popup will
display a list of providers matching the search parameters, and the
user can select any of them by checking one, and the fields on the
form on the parent window displays the values for the checked
provider. And when the user selects another provider from the
results, the form updates itself on the parent window. Did I get it?
Well, if I'm close anyway, maybe what I'm thinking will work.
I would solve this problem by having the popup concentrate on
searching for a provider, and leave the problem of populating form
fields to the calling (parent) window.
The popup would have a reference to the parent, so I can call a JS
function on the parent. With JS, even the function to call can be
dynamic, so it could be a parameter that the parent window sends to
the popup ("call my 'showProvider' method when the user selects a
provider"). The parameter to the "showProvider" method would be the
provider ID.
When showProvider is called, it would send an XMLHttpRequest to
retrieve the details of said provider. I'd have a method which I can
call with the XML result of the call, as well as the form name or form
variable, and will begin to populate the fields that it finds. With a
decent naming convention, I can write this method so that I can reuse
it whereever I have this form.
The reusable portions would be the popup (completely parameterized),
the XMLHttpRequest handling, the form population function, even the
method that gets called when a provider is selected. The form names
would have to match across all the pages using it.
Hope this helps. Let me know if you want me to clarify any point.
Sorry if I misunderstood your problem and offered a bogus solution.

Earlier the question was just "Can I?" Now it's "Can I, with externalized styles?" Anyway, JSF is a component-oriented framework, and a higher level of abstraction than Struts. Because of that, it's not surprising that you lose some lower-level control. I guess you'd just have to be careful with which set of components you use.

Re: java.util.Date in Action Form Bean
This is exactly what FormDef does. It reads your existing bean and configures a form bean for it. Reuse. You can continue to use BeanUtils with the FormDef-configured beans as you would any other form bean, or you can also use FormDef's setFormValues()/getFormValues() and take advantage of its formatting/parsing functionality.

It is not recommended that you use fields other than String and boolean in your form beans. The form bean is where the request parameters are stored before your fields are even validated. If validation fails, you'd ideally want to preserve what the user typed in so s/he can correct his/her input. For instance, if the user typed in "1q3" in field that's meant to hold a numeric value, the field will be marked invalid and the form will be shown to the user again. If the form bean used a String for this property, the user will see the "1q3" value on the input control. If the form bean used an int for the property, the attempt to populate that field with "1q3" would fail and the user would see "0" instead. The same thing applies to date fields. I don't even know what will happen if the user typed in "35 Se[ 2005" on a field that's declared as java.util.Date. The best approach is to use String fields, so the user's input is preserved, and in the case of user errors, they will be able to edit the values they typed in instead of starting over again. Of course, each application has its own set of circumstances, so this may not be an issue for you. If you're still interested in checking out FormDef, though, take a look at http://www.rabago.net/struts/formdef/dev/nested.htm .

You can set the form's scope to "request". This way, the values don't

How the global converter handles this? Instead of the format itself, you can specify a key into your application resource files: In your resource files, define the format you want to use for that locale: in example.properties (default for Aus?): format.date=dd/MM/ in example_en_US.properties: format.date=MM/dd/ The binary download for FormDef includes locale.war which demonstrates this capability. hth, Hubert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Or is it too much work? I've wondered about this feature, but there are some problems. (Not to mention, this is the first time someone asked for it). For instance, what if the form defined isn't a DynaBean? And how would I let the user specify formatting requirements (for dates, numbers, etc)? Still, it's feasible. It's just sort of a reversal of what I tried to do. I wanted to reduce config info. If you defined your form one field at a time in struts-config, then defined them again in formdef-config, then you end up with two places you have to keep in sync. Not to mention validation.xml (if you were using it for that form). With the form defined in FormDef, you're sure the fields on the bean are represented on the form, and they're always in sync. Form field types already default to java.lang.String. You can even put validation rules right there! > In a way, this is similar to explicitly supporting all HTML tag > attributes in Struts tags instead of supporting whatever a developer > put into a tag as attribute, and to let user agent care about that. Not really. The reason the support is there is to allow you to add fields to a form that would otherwise limit you. If UserInfoBean had "username" and "password", the following: ... would give you a dyna form with "username" and "password" string fields. That said, you can customize each field the way you would a property configured in struts-config. Okay, that part's like the tag attribute support you mentioned. However, FormDef allows you to add fields to your form and not be limited by UserInfoBean: ... would give you a dyna form named "LogonForm" with "username", "password", and "selectedButton" fields.

[ Oh, I missed my cue! :) ] If your form bean maps to a business object (and it sounds like it does since you're using BeanUtils), you can try FormDef: http://formdef.dev.java.net/ You won't need to create a separate ActionForm class or manually define your DynaActionForm, FormDef will configure it for you. You can also specify how you want your fields formatted, including dates and numbers, and use FormDef's conversion methods in place of BeanUtils.

I'd probably try option (2). You can take a look at the struts-examples.war sample application [included in the struts download] for an example of how this is done. > > Awaiting your replies and Thanks in Advance > > Sajid Hubert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Record locking
For web applications, I tend to think that the more appropriate approach is (what I know to be called) optimistic locking. When a user edits a record, I keep track of the update timestamp (or even better, an update sequence number) of the record selected. This value gets sent back when the user attempts to save the changes. Before persisting the changes to the DB, I check if the timestamp (or seqnbr) still matches the one on the DB. If so, then no one else has modified the data and the update can proceed. If not, then it's up to you - you can show the user the new record values and the changes that s/he made, or ask that the user re-enter changes, etc. In your example, User B will be shown an error message saying the record has changed since he began and can start over or go ahead and proceed with his changes anyway.
