RE: Transfer Object in JSF, Spring, and Hibernate
Hi Caroline, IMO Transfer Objects were invented to combat the problem with transferring heavyweight EJB 2 beans around. EJB3 beans are much lighter, or you could be using POJOs instead, in which case you may not need the Transfer Object. I would use the managed beans of my JSF application as Controllers / Handlers which pass the values to the business beans. The use your ORM (JDO / Hibernate) to pass these business beans to the database. No need to duplicate the same beans, just to pass them around. You can use your managed beans to convert things like y/n to true/false in the business bean, or use the ORM layer to convert them as they are passed to the database. If you set up your ORM layer correctly the business beans do not have to correspond to the database tables - this is the whole point of the Object Relational Mapping!

RE: JSF Value Binding Technique
Hi Bansi,
Is B a managed bean as well?
You might have to explicitly call the getter for id in B
i.e. value=#{backingBean.A.B.getId()}

Subject: JSF Value Binding Technique
Wondering if its feasible to set the values for java.util.Set using JSF
value binding expression
For example
h:selectOneMenu id=contact value=#{backingBean.model.contacts}
f:selectItems value=#{backingBean.contactList} /
/h:selectOneMenu
Please note contacts is defined as java.util.Set in model
I have one more question on Value Binding
Here is the situation
I have two model/pojo classes
Example:
Class A{
private B b;
}
Class B{
private long id;
}
The jsf page has following snippet
h:selectOneMenu id=ptrType value=#{backingBean.A.B}
f:selectItems value=#{backingBean.ptrTypeList} /
/h:selectOneMenu
Here is backing bean snippet
ListSelectItem ptrTypeList = new ArrayListSelectItem();
ptrTypeList.add(new SelectItem(10,Primary PTR)); ptrTypeList.add(new
SelectItem(20,No PTR)); return ptrTypeList;
So the JSF page shows a dropdown list of values. When i pick a value
from the list it should set the value to the id attribute in Class B
i.e. h:selectOneMenu id=ptrType value=#{backingBean.A.B.id}
I am getting error Target is Unreachable
I have setter/getter methods in both Class A B
Please note hibernate mapping file shows the relationship between A and
B as the id in class A is foreign key and references id as the primary
key of class B
Any pointers/suggestions will be highly appreciated

Bansi

Is it a typo, or do your getter and setter not match the variable

Subject: Re: 1.1.5 and t:selectOneMenu
Citando Mike Kienenberger [EMAIL PROTECTED]:
Short answer: Old behavior was broken. New behavior matches the
spec. Long answer: Read through this thread, probably starting at the
beginning (postings after the one below probably aren't relevent to
your issue):
http://www.mail-archive.com/users@myfaces.apache.org/msg34395.html
Solution: Make sure that your itemValue attributes have value
bindings that return the correct type. If your value points to a
Long, this can be as simple as using #{3} to return a Long 3.
Otherwise, you'll have to convert or fetch the correct value type
yourself.
Nice Long-term solution: submit a patch for Tomahawk selectItem so
that it automatically coerces the type like the old f:selectItem
component used to do.
a big thanks, but I don't understant what selectItem has to convert:
this is the tag:
t:selectOneMenu value=#{mb.id_cassa_int}
f:selectItems value=#{mb.dblCasse.rows}/
/t:selectOneMenu
this is the id_cassa_int declaration:
private int id_cassa_int = 0;
public int getId_cassa_fat() { return id_cassa_fat;}
public void setId_cassa_fat(int id_cassa_fat) { this.id_cassa_fat =
id_cassa_fat; }
selectItems points to an ArrayList of selectItem, filled with strings,
where Value is converted from Int.
So, why does it need to convert something ?
really thanks,

RE: Navigation Rules - Model based (dynamic) navigation support possible?
Hi Thorsten, Have a look at the reply to this mail. http://www.nabble.com/Changing-JSF-scenario-at-runtime-tf395068.html#a10 88201 Hope this helps, Fintan -Original Message- From: Mike Kienenberger [mailto:[EMAIL PROTECTED] Sent: 16 April 2007 15:09 To: MyFaces Discussion Subject: Re: Navigation Rules - Model based (dynamic) navigation support possible? Use a custom NavigationHandler. :-) That's why the hook exists, so not using it is like saying you want to develop a JSF application without using JSF. Have you ever used JDeveloper? (free download from Oracle, so if not, download it and take a look) Basically, it uses the exact process you describe (model showing pages as objects, the user draws lines between the pages and labels each line with the outcome on which to navigate from one object to the next), and creates the navigation rules from it. It sounds like the only difference between what you want and what JDeveloper demonstrates using the standard NavigationHandler is that you want to change the rules on the fly.Seems like that should be a fairly straight-forward customization of the existing handler -- worse case you'd copy the NavigationHandler source code, and change it to fetch data from an internal data source instead of a static set of rules read from the config file.And if you did it in a generic enough way, we might even be able to make it a configurable option for MyFaces where all you need to do is supply an alternate rule data source in your config file rather than providing an entire new navigation handler. If nothing else, we could probably support it as a Tomahawk option. Tomahawk already is set up to share code with MyFaces, so it should be trivial to push the navigation handler into the shared core project, add the hooks to customize it from Tomahawk, and create a Tomahawk subclass to make use of those hooks. On 4/16/07, Torsten Krah [EMAIL PROTECTED] wrote: By default jsf is using a outcome based navigation model. But consider a content managment system, where the user can model navigation decisions by drawing connections from one object to another. Data is modeled in some known way to map them to an url, navigation between this model can be defined from the user. The object defines the view to be rendered, how to navigate through the views, when the navigation decision is done in the model (have to be done there to be changeable by the user). How could this be done with JSF. Navigation rules have to be there before starting the webapp. So how can a navigation be handled in a jsf compatible way, to support dynamic made navigation rules in the model tier (and maybe support url based navigation). Is there any good way to do this, maybe some thought?

RE: Cross validation problem
Hi Stephane,
One way to do this is to set a hidden field as the *last* component on
your page.
h:inputHidden id=loginCheck validator=#{backingBean.validateLogin}
value=needed
Note : you need to have some value for the field, hence 'value=needed'
When you run your validation on this component all the others have been
set.
backingBean is your backing bean with a validateLogin() method.

What other ways such a problem can be handled? You can use JBoss Seam or Apache MyFaces Orchestra (which is the successor of the MyFaces conversation tag). JBoss Seam is a rather full blown thing which can do much more please refer to their homepage for further informations. Orchestra in contrast is relatively young and you have to use svn [1] to get in touch with it. It uses Spring to provide two new scopes - a conversation scope and a flash scope. In the svn checkout you will find some examples and xdocs which should help to jump up. The website should be online within the next week. Compared to Seam - Orchestra is very feature less, it just tries to solve the problems you have together with ORM mapper and it do not use annotations, but you can use it without ORM too ... thats the nice thing, its just a matter of configuration - and IMHO its a little easier to understand.

RE: setting default value for input field?
Hi David,
One approach for textual values is to put the value e.g.
requestedNodeResults in a message properties file and call it like a
message text.
For the param.searchScope - I think that JSF requires most things in
managed beans. What you could do is define a Defaults bean, which would
hold all of the application scoped defaults. The bean itself would have
getters and setters for each property.
E.g.
managed-bean-name
managed-bean-namedefault/managed-bean-name
managed-bean-classDefaults/managed-bean-class
managed-bean-scopeapplication/managed-bean-scope
managed-bean-property
managed-property
property-namenodeResults/property-name
value15/value
/managed-bean-name
/managed-bean-property
managed-bean-property
managed-property
property-namescope/property-name
value#{param.searchScope}/value
/managed-bean-name
/managed-bean-property
/managed-bean-name
Defaults.java
-
public class Defaults {
private int nodeResults;
private String scope;
public int getNodeResults() {
return nodeResults;
}
public void setNodeResults(int results) {
nodeResults = results;
}
public String getScope() {
return scope;
}
public void setScope(String scope) {
this.scope = scope;
}
}

I need to convert this struts form:
html:hidden property=scope value=${param.searchScope}/
html:hidden property=requestedNodeResults value=15/
html:text property=query styleClass=search/
to a JSF form, but i don't know where to put the '15' and
'param.searchScope' in JSf
setting h:inputHidden value=#{theForm.requestedNodeResults}/ does

like that? Can't find documentation on setting default form values...

RE: MessageBundle: internationalization problem
But seriously folks, this might be a good way to test changes to the properties file. Write the new changes in your Zulu properties file, change the locale in your browser to Zulu and check the new changes are OK. If something is wrong, you simply keep your original properties file. If the changes are OK, just change the '_zu' part of the new properties file (overwriting the original) and you are good to go. Gives a different meaning to localisation testing? -Original Message- This is also the way to slip in some jokes; you could e.g. use a weird extention never used at your place (like the one for swahili) to provide a local German dialect version of your app. (to make that work, your users would of course add that to their browser languages... ) * ** *** ** * ** *** ** * ** *** ** * This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

RE: very simple question regarding h:inputText
I have to disagree. The way that I read Martin's setup is that Martin is keeping the UI/navigation logic of his application in a different class/layer to the business model. (You may correct me if I am wrong) I like the fact that I can use a simple POJO (business model) as the centre of my application. In my applications the business model is a managed bean. Using JDO I can also persist this POJO to the database in a similar fashion. In order to keep View and Control separate from the Model I use aspects to capture the navigation and persistence stuff. Thus I do NOT duplicate any business logic, and I keep the Model separate from and View or Control logic. -Original Message- From: Iordanov, Borislav (GIC) [mailto:[EMAIL PROTECTED] Sent: 22 August 2006 22:00 To: MyFaces Discussion Subject: RE: very simple question regarding h:inputText That's point.

RE: many components to one (or more) validation?
Hi Joe,
If you bind each component in the group to a backing bean, then you
attach a custom converter to the last control of the group that appears
on the page (e.g. input field).
public class BackingBean {
private SelectOneRadio radio;
private UIInput radioInput;
...
public void validateRadioText(FacesContext context, UIComponent
component, Object value) {
Boolean buttonClicked = ((Boolean)
radio.getLocalValue()).booleanValue();
String radioText = (String)value; // 1
if (buttonClicked) {
if(!validText(radioText)) {
FacesMessage message = ...;
throw new ValidatorException(message);
}
}
}
Private validText(String textToValidate) {
// validate the text here
}
...
}
NB - The last component will not have its local value set yet (see //1)
In the JSF page set the validator of the last component to this
validator method
t:inputText value=#{...} binding=#{bb.radioInput}
validator=#{bb.validateRadioText}
Where bb is set as a managed Backing Bean in faces-config.
Alternatively you could use a hidden field which is the last field on
the page :
h:inputHidden validator=#{bb.validateRadioText} value=needed/
In this case you get the value for radioText (see //1), similarly to how
it was gotten for buttonClicked, as the local value has been set.
Otherwise you can define your own component similarly to above, if you
will need this functionality in more than one page.

Fintan

Hello,
Is it possible to have more than one component validated as a group? For
example: let's say I've have a radio button that when activated, text
must be entered/validated in that radio button's associated input field?
In other words, only when the radio button is selected, should the input
filed be validated.
Thanks,

RE: [newbie] MyFaces or Barracuda ??
Hi Cyrille, I would suggest a Persistence framework for firing your objects into and out of the database. Something like JDO - a free and highly polished implementation of this is JPox. IMO this will be a lot less bother than having to learn JDBC, which is the basic method of communicating with the database (JPox does the work of translating your calls into JDBC calls). I would be wary of trying to learn too much at once unless the cost of learning the framework is less than the cost of learning how to do things without the framework. Therefore my minimum framework stack would be : MyFaces to build the UI and map your UI components (textboxes, etc.) to your business logic classes (backing beans) JPox to persist these same business logic objects to the database. This way you use the same class in the middle tier (business logic) to map (1) to the Web page and (2) to the database. Once you have these working you can look at introducing frameworks like Spring, etc. Unfortunately I have not seen Barracuda and so cannot comment on it.

RE: components and valuechange events - forgotten update of othercomponents watching the same backing bean attribute - Updates lost onbacking bean when the last rendered component isn't used
Hi Torsten,
You mention that the last rendered component is the value that is used.
Would a hidden component at the end of the form, which is set to the
changed value work for you?
Failing this you could use JavaScript to make sure that both selectOne
values are changed when one changes.

Subject: components and valuechange events - forgotten update of
othercomponents watching the same backing bean attribute - Updates lost
onbacking bean when the last rendered component isn't used
Hello.
I've got 2 components, watching one backing bean value:
h:selectOneMenu value=#{tableData.country}
onchange=submit() immediate=true
valueChangeListener=#{tableData.countryChanged}
f:selectItems
value=#{tableData.countryNames} /
/h:selectOneMenu
h:selectOneMenu value=#{tableData.country}
onchange=submit() immediate=true
f:valueChangeListener
type=my.examples.CountryListener/
f:selectItems
value=#{tableData.countryNames} /
/h:selectOneMenu
If i change the value of the one component, the other dont get it - of
cause, because the new value is in the event object and these are
processed later, the other component saw the old value, which is changed
after that - so the component missed the update.
Doing a second submit of another kind, shows the correct active value
for the attribute watched, now correct on the former wrong displayed
component. How to solve this problem, that a value may be watched by
different components ( doesnt matter if the components use the same
listener or not ). ?
Lets call the above problem X.
Now it also happens, that if another valuechangeevent for another
component is thrown and the View gets updated, X shows the wrong active
value, the one of the X component which didnt get updated right.
example:
Y: 10
X1: en
X2: en
click on X1: change it to - de
update view shows:
Y: 10
X1: de
X2: en
The UI is now rendered with german messages from the de_DE message
bundle.
now click on Y and change it to 5:
updated view shows:
Y: 5
X1: en
X2: en
But the UI is still in german text, not english - the value of the
backing bean is en, making some updates on Y from 10 to 5 or 20 shows en
in the backing bean, but somewhere the UI forgot to change the locale
back.
Testing a little bit, it seems that the last rendered component watching
this value is the one which counts, regardless if other components
rendered before does some changes to the value of the backing bean, the
value of the last one overrides - although the first ones do update the
view to the correct languages, the event gets called. If i only use the
last rendered component watching the value, backing bean value gets
updated right every time - although the other ones still lack the
problem mentioned X above.
Hope its not to confusing ;).
Bug or not, any solution for the tow problems or am i doing a fatal
mistake here?
kind regards
Torsten

Subject: Beginner: html-attributes and bean-values
Hello,
it's me again with a non magic beginner question;):
We've got some html templates from our web-agency.
I like to use them in my JSF pages.
In the html template I've got for example the following line:
DIV class=navigationActive lorum /DIV
I need to replace the class-style with a managed bean property and tried
the following:
1.) DIV class=h:outputText value='#{mybean.value}'/ lorum
/DIV
2.) DIV class=${mybean.value} lorum /DIV
Nr 1) doesn't work, because the beans value is not placed between the
attributes double quotes.
Nr 2) seems not to work on the first JSF request. An empty String is
returned. On following requests this works.
What is the correct and easy way to populated JSF bean values into
already existing HTML-Code?
Thanks and Greetings
Chrisi

RE: Need to use Spring
Hi, I use JSF, but I do not use Spring at all in my applications. I use JDO to persist my objects to the database, but can use any database technology - including writing the JDBC code yourself, instead of Hibernate. The good thing about Java is that you have a wide choice as to what technologies to use. Spring, JPox (my choice of JDO technology), Hibernate, Ibatis and many, many more frameworks are available - if you want to use them. If you are learning one technology e.g. JSF, you may find it easier to not use any other frameworks until you are confident in that technology. Then you could look at adding another framework, e.g. JDO to store/retrieve data from the database. This way you are only looking at one new technology at a time. If you tried to start from scratch and learn 3 or 4 technologies at once you are bound to find yourself very confused. In short JSF does not require you to use any other technologies.

RE: saveState question
Title: Message
Hi
Yura,
The
simplest way to pass data from page1 to page2 is to use
onemanaged bean, and use t:saveState on both pages referring to that onemanaged bean.
If the
managed-bean is in request scope, then when you move from page1 to page2 you
will lose the data in managed-bean - unless you are using t:saveState. If
you have t:saveState on page1 and page2 which references managed-bean, when you
leave page1 saveState saves the state of managed-bean. Then when you enter
page2 saveState reads the state of managed-bean and restores the data saved from
page1.
check
out :
http://wiki.apache.org/myfaces/How_JSF_State_Management_Works

another way which does not involve t:saveState, look at :

It will work because the style is set depending on the row variable yourVar.

To get this to work for the entire row you will need to add the :

RE: Retrieving component values in validation methods
2) Which is the right method to get the values of other components in
the validator method, getSubmittedValue(), getLocalValue(), dependent
on configuration issues (immediate) of the component owning the
validator and other components asked in the validator method?
Would the following work for you?
(Taken directly from Core Java Server Faces book)
The trick is to attach the validator to the last of the components. By
the time its
validator is called, the preceding components passed validation and had
their
local values set. The last component has passed conversion, and the
converted
value is passed as the Object parameter of the validation method.
Of course, you need to have access to the other components. You can
easily
achieve that access by using a backing bean that contains all components
of the
current form. Simply attach the validation method to the backing bean:
public class BackingBean {
private UIInput dayInput;
private UIInput monthInput;
...
public void validateDate(FacesContext context, UIComponent
component,
Object value) {
int d = ((Integer) dayInput.getLocalValue()).intValue();
int m = ((Integer) monthInput.getLocalValue()).intValue();
int y = ((Integer) value).intValue();
if (!isValidDate(d, m, y)) {
FacesMessage message = ...;
throw new ValidatorException(message);
}
}
...
}
Note that the value lookup is a bit asymmetric. The last component does
not
yet have the local value set since it has not passed validation.
An alternative approach is to attach the validator to a hidden input
field that
comes after all other fields on the form.
h:inputHidden id=datecheck validator=#{bb.validateDate}
value=needed/
The hidden field is rendered as a hidden HTML input field. When the
field
value is posted back, the validator kicks in. (It is essential that you
supply some
field value. Otherwise, the component value is never updated.) With this
approach, the validation function is more symmetrical since all other
form
components already have their local values set.

Both will break the user work flow, because the selectOneMany or the edit details link comes logically before some other input components, or worse, depend on the selection of the selectOneMenu or selectOneRadio - that would cause that the user has to input mandatory info which is not relevant or required after the selection, which may show a partly different form. * ** *** ** * ** *** ** * ** *** ** * This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

RE: Redisplay a JSF site after submit with the scrolling state previously used?
Hi, Would the new focus component in the sandbox achieve this? I.E. if the component which receives the focus is not on the first screenful, will the browser automatically scroll to the component which has the focus?

November 2005 16:26 An: MyFaces Discussion Betreff: Re: Redisplay a JSF site after submit with the scrolling state previously used? Matthias, There's already javascript support in MyFaces for doing autoscrolling. Currently, it always scrolls back to the UICommand component that submitted the form. I've tried to write my own javascript that scrolls it to any arbitrary component on the page, but I don't really know javascript. It'd be great if you could figure out how to take advantage of the existing autoscroll javascript to make it work with arbitrary components. Maybe we could then figure out a tag to set the autoscroller -- f:setAutoScrollToHere or something like that :) On 11/26/05, Matthias Kahlau [EMAIL PROTECTED] wrote: Hi! I use a method for valueChangeListeners of selectOneMenu and other multi choice tags. In the valueChangeListeners method, I can set the state of boolean variables, which are used in the JSF site in attributes like disabled and rendered of some tags. A valueChangeListener method is invoked when the value of the related tag changes, which causes a submit of the form. The problem is, that some tags are below the fold, and when the form is submitted because of a value change and then redisplayed again, the site is scrolled to top, and the user has to scroll down to the component, where he changed the value. Does somebody know if it is possible to redisplay the site with the scrolling state previoulsy used? (I know that I could alternatively set the disabled and rendered states of the tags by using client-side JavaScript, without submitting the form and changing the scrolling state, but that's more work and doesn't use the server-side facilities).

ADF Faces is part of the JDeveloper/ADF package, which license is currently $995. ADF Faces, as you probably know, is still not production and as such does not currently land in the license swamp and as such is free to use, but as soon as we go production they will follow what ever license term comes with JDeveloper and ADF. One of the reasons why we have not talked much about this is that we have proposed a new license to upper management and have been waiting for approval, and believe me when I say that these things take forever. There are so many things to take in account before something like this can get approved e.g. legal, current customers etc...

RE: Cross component validation question
Use a hidden field on the form. Associate a custom validator with the hidden field. When the application is submitted, the custom validator compares both text field and combo box and throws a validation error only if both are null.

Because, the need to get another component's could arise in the following scenario too... ( I had this scenario ). On a form I have few input fields. One of them is school name. The school name can be input by choosing from a drop down or by entering in a text field, this piece of information is required, but I cannot set the required attribute to true because the user could choose or enter in the text field. So in my validator of the drop down I get the submitted value of the text field and if both are null throw a validator exception.
