Localized String with params - Value Binding Expression...

Hi All:
I see many e.g.s where a command button / or a label's value can be a localized resource string using the generic value binding expression:
"#{bundleVarName.keyName}"
what if the resource string has parameters? for e.g.
button.caption = Click Me for {0}
Can we assign a value binding expression with params for button captions etc.
Please help - I am a newbie in JSF,,,
regards
-Somesh

JSF developers have forgotten about this :)
Use other tools for displaying such messages (f. e. JSTL) where you need to have parametrized messaged.
But mostly, non-parameterized JSF will be enough.

Using value binding expression for to-view-id

hi;
is it possible to use a value binding expression in the <to-view-id> element?
if not, is there a logical reason for this?
thanks

Shrek-2:
Are we there yet?No
Are we there yet?No
Are we there yet?Yes
Really?
NO
Seriously, the default navigation handler does not allow to use EL for the to-view-id, but you can obtain the desire behaviour with the custom handler decorator.
This is a code snippet:
     public void handleNavigation(FacesContext fc, String actionMethod, String actionName) {
          _base.handleNavigation(fc, actionMethod, actionName);
          String viewId = fc.getViewRoot().getViewId();
        if ((viewId.indexOf("#{") != -1) &&
                (viewId.indexOf("#{") < viewId.indexOf('}'))) {
             String bviewId = (String)fc.getApplication().createValueBinding(viewId).getValue(fc);
             if (bviewId != null)
                  fc.getViewRoot().setViewId(bviewId);
             else {
                  // you can throw the exception here
     }More about HandlerDecorator:
http://www.jsftutorials.net/jsfNavigation/jsf-login-navigation-redirect.html
http://www.jsftutorials.net/faces-config/navigationDecorator.html
P.S. Note: This feature might broke the separation between the different levels of application from the architectural point of view. Hard-coding the ViewIds inside the java code is not a good idea at all.

well, i figured out the problem so thought to share with all aswell.
all i changed was the name of the variable from mDept to dept.
java beans has its own set of rules and naming conventions which i have not read much about but this problem had to do sumthing with that!
just changing the name simply works fine!

Exception handling within a value-binding expression

Hi all,
Forgive me if this question seems odd, but I am a long-time Struts developer, new to JSF.
In Struts, exception handling was easy because all requests were funnelled through some subclass of Action. Exception handling could effectively be consolidated into one spot by applying the template-method pattern.
Of course, with JSF, this is not possible because method names in value-binding and action-binding expressions can be chosen arbitrarily. For this reason, I am exploring aspect-oriented (and other) techniques for consolidation JSF exception handling into one spot, but rather than focus too intently on that, it's clear that I first need the ability to forward to an error page when an exception is encountered in a value-binding or action-binding expression.
For action-binding expressions, ExternalContext.dispatch("<view id>"); seems to work quite well, but I am unable to make the same work when in the context of a value-binding expression. This is probably attributed to the fact that at that point, I am in an entirely different phase of the JSF request processing lifecycle.
What I'm looking to know is if anyone has a reliable means of forwarding to an error page within the context of a value-binding expression. Better yet, does anyone know a reliable way of forwarding to another view regardless of what phase you are in?
If it makes a difference (and I think it does) the error page uses JSF as well, and uses the same layout (provided via custom tags courtesy of JSP 2.0 tag files), so some view components would have the same name as the page which encountered the error. This seems to get in the way of me simply defining the error page for a 500 in my web deployment descriptor.
Thanks in advance to anyone with a working suggestion.
-Kent

Let me pose a purely hypothetical use case to demonstrate the problem:
Imagine a page in an HR app, employeeDetails.jsp, that displays an always-up-to-date combo box which lists employee names and IDs. onChange triggers a form submit with the intention of simply posting back to this page, with various text boxes, etc. below updated to show all information for the selected employee.
Obviously, with the requirement that the combo box always be up to date, it's clear that the getter invoked by the value-binding expression must access the database (not directly of course, but via a facade, application, then data-access layer). Any unexpected and unchecked exception in this chain would propagate back up to the getter method on the backing bean. I need to, at that point, log the exception (trivial) and forward to a user-friendly error page.
I suppose I could put some contraint on myself that data access is only performed within ActionEvent handlers, but I'm not sure that's consistent with the JSF model in general, in fact it almost seems Struts-like in that I'd have to invoke some action before loading this form to build the up-to-date list for the combo box, shove it in request scope, where it's then available to the page indicated by the navigation rules. Submission of the form on the page in question would also need to result in rebuilding the up-to-date list. Now we're looking at firther propagation of code. I want to avoid this, so I am looking for a better way.

How Can I replace newScale Text Strings with Custom Values?

How Can I replace newScale Text Strings with Custom Values?
How can I replace newScale text strings with custom values?
All newScale text is customizable. Follow the procedure below to change the value of any text string that appears in RequestCenter online pages.
Procedure
1. Find out the String ID of the text string you would like to overwrite by turning on the String ID display:
a) Navigate to the RequestCenter.ear/config directory.
b) Open the newscale.properties file and add the following name-value pair at the end of the file:res.format=2
c) Save the file.
d) Repeat steps b and c for the RmiConfig.prop and RequestCenter.prop files.
e) Stop and restart the RequestCenter service.
f) Log in to RequestCenter and browse to the page that has the text you want to overwrite. In front of the text you will now see the String ID.
g) Note down the String ID's you want to change.
2. Navigate to the directory: /RequestCenter.ear/RequestCenter.war/WEB-INF/classes/com/newscale/bfw.
3. Create the following sub-directory: res/resources
4. Create the following empty text files in the directory you just created:
RequestCenter_0.properties
RequestCenter_1.properties
RequestCenter_2.properties
RequestCenter_3.properties
RequestCenter_4.properties
RequestCenter_5.properties
RequestCenter_6.properties
RequestCenter_7.properties
5. Add the custom text strings to the appropriate RequestCenter_<Number>.properties file in the following manner (name-value pair) StringID=YourCustomTextString
Example: The StringID for "Available Work" in ServiceManager is 699.
If you wanted to change "Available Work" to "General Inbox", you would add the following line to the RequestCenter_0.properties file
699=General Inbox
Strings are divided into the following files, based on their numeric ID:
Strings are divided into the following files, based on their numeric ID:
String ID File Name
0 to 999 -> RequestCenter_0.properties
1000 to 1999 -> RequestCenter_1.properties
2000 to 2999 -> RequestCenter_2.properties
3000 to 3999 -> RequestCenter_3.properties
4000 to 4999 -> RequestCenter_4.properties
5000 to 5999 -> RequestCenter_5.properties
6000 to 6999 -> RequestCenter_6.properties
7000 to 7999 -> RequestCenter_7.properties
6. Turn off the String ID display by removing (or commenting out) the line "res.format=2" from the newscale.properties, RequestCenter.prop and RmiConfig.prop files
7. Restart RequestCenter.
Your customized text should be displayed.

I've recently come across this information and it was very helpful in changing some of the inline text.
However, one place that seemed out of reach with this method was the three main buttons on an "Order" page. Specifically the "Add & Review Order" button was confusing some of our users.
Through the use of JavaScript we were able to modify the label of this button. We placed JS in the footer.html file that changes the value of the butt

Using value binding expressions to set 'required' attribute

I am trying to use a value binding expression to determine whether the value of various input control's is required or not according to where they are used and not having much luck. I wonder if anyone can shed some light on this...
The following expression works: <h:inputText id="name" required="#{true}"/> whereas <c:set var="required" value="true" scope="request"/>
<h:inputText id="name" required="#{required}"/> does not, even though the expression evaluates to true! I have tried numerous variations (requestScope.required, required == true, required ? true : false, etc.) to no avail. Interestingly, #{1 == 1} or binding to a backing bean method works, but as soon as you add a request variable it breaks.
Am I doing something wrong, is this something that JSF doesn't allow, or just a bug in the RI? Note that I don't want to vary this flag between multiple submissions of the same form, I am just trying to reuse the same JSP include to generate form controls for required and optional data on different forms to avoid a whole lot of cutting any pasting.
Any pointers gratefully received.
-- Keith Wilson

I had something like this happen, and here's what I concluded the problem was. Perhaps your problem is similar.
In the first non-working example you show a request-scope variable being set in the JSP page, and then use that to set the "required" attribute. But consider what happens when you submit the form. There is no longer any request-scope variable set because we have a new request and we don't go through the JSP page! (Not before validation is checked, anyhow).
So basically I concluded that the variable had to be in (say) session scope for it to work as you would like.

Replacing the same value in a string with varying values

If I have a string:
"%s is the %s I am referring to"
and - I want to replace the %s occurrences with DIFFERENT values... what's the best way to do this.
I was thinking parsing it into seperate strings using substr and instr but, I'm not sure if that's overkill or not.
Replace is ideal but - it replaces every occurrence so - you can state just replace the first occurrence with one value and the second with another (i.e. if the desired result after replacing the above string was supposed to be "This is the string I am referring to"
Any help is appreciated.
Thanks

Explain how you get those results from that data.
Always say which version of Oracle you're using (e.g. 11.2.0.3.0).
See the forum FAQ {message:id=9360002}

There's no way to tell it (for example) to change only the first one.
REGEXP_REPLACE, is a lot more flexible. It does have an option for giving a specific occurrence, but you may not even need that feature. You might just want something like
REGEXP_REPLACE ( '%s is the %s I am referring to'
            , '(.*)%s(.*)%s(.*)'
            , '\1This\2string\3'
            )It all depends on your data and your requirements.
Are the new values (such as 'This' and 'string') fixed, or can they change from row to row?
Will you always have 2 (or some known number) of '%s's in the original string?
Does '%' always signal something that is to be replaced? If not, how can you tell when it does and when it doesn't?
Does 's' always come right after '%'? If not, what are the possibilites, and what do the different characters signify?

Parsing strings with Unicode values 16 bits

How can I get the Unicode value for a character in a String when the value is greater than 16 bits?
I need to extract a supplemental plane Unicode value from a string. However, String.charCodeAt(index) truncates the Unicode value to 16 bits, returning what should be 0x02F91A as 0xF91A. I see discussions that show that earlier versions of Flex stores such char codes as the two code points of a surrogate pair, but in Flex 4, the string length is just 1 when I put only this character in the string.

Does it work in JavaScript? Could send it over via externalInterface.

How to store string with "?" without binding parameters

How to split a string with a delimiting regular expression like "\r"

Hello!I am a fresh in java programming.Please don't deride my question.What I want to realize is to get the current caret lines and cols in a JTextPane. My question is :After I fetch the string content of the JTextPane and try to split it with the end-line token like "\r" or "\r\n",it always comes me an wrong position.
here is my code:
public void caretUpdate(CaretEvent e) {
int ln,col;
JTextPane textSource = (JTextPane)e.getSource();
String sourceString = textSource.getText();
String subString = sourceString.substring(0,
(e.getDot() == 0) ? 0 : e.getDot()-1);
String[] splitString = subString.split("\r",-1);
ln = splitString.length;
col = e.getDot() - subString.lastIndexOf("\r");
setCaretPosition(ln,col); //display ln and col in a label
I have got puzzled>_<.Please help me.Any help would be appreciated . (^-^)

Swing text components always use "\n" to separate lines, not "\r" or "\r\n". When you read text in from a file or paste from the clipboard, the line separators are converted to "\n" if necessary. They save the info about what line separators were used in the source file, so if you write the text back to a file it converts them back.

Binding expressions and collections

<quote>
In addition to being able to read the initial value of a field from an object, value binding expressions can also be used to navigate maps, lists, or arrays. Here are some examples:
#{foo[bar]}
#{foo["bar"]}
#{foo[3]}
#[foo[3].bar}
#{foo.bar[3]}
</quote>
Could anyone explain how does it work ? Is foo is always bean ?
Isn't #{foo["bar"]} identical to #{foo.bar}
Also in "Core JSF" they say #{foo.bar[3]} doesn't work if bar indexed property of a bean.
<anotherquote>
The syntax of a method binding expression has two primary formats:
#{expr-a.value-b}
#{expr-a[value-b]}
The first format is a classic DOM-style object tree structure. The second format can be used to call a method pointed to from an object array, Map, or List.
</anotherquote>
The same question how to use the second form.

An expression is a little piece of softwaremuch like a scriptthat evaluates to a single value for a single layer property at a specific point in time. Whereas scripts tell an application to _do_ something, an expression says that a property _is_ something.
With expressions, you can create relationships between layer properties and use the keyframes of one property to dynamically animate other layers. For example, you can use the pick whip to link path properties, so a mask can take its path from a brush stroke or a shape layer object.
The expression language is based on the standard JavaScript language, but you do not need to know JavaScript to use expressions. You can create expressions by using the pick whip or by copying simple examples and modifying them to suit your needs.
Be sure to read the
"Expressions" section of After Effects Help on the Web.
Dan Ebberts has an excellent collection of example expressions and scripts and tutorials for learning how to work with expressions and scripts on his website: http://www.adobe.com/go/learn_ae_motionscripthome.

Question on value binding

Hi I am trying to put 2 value binding statements into one method "ok()" in the backing bean. here they are.
     FacesContext context = FacesContext.getCurrentInstance();
     ValueBinding vb = context.getApplication().createValueBinding(
               "#{LoginBean.subject}" );
Subject subject = (Subject)vb.getValue( context );and
     FacesContext context = FacesContext.getCurrentInstance();
     ValueBinding vb = context.getApplication().createValueBinding(
          "#{UserGroupBrowserBean.selectedGroupName}" );
     vb.setValue( context, newGroup );This is giving me the error when i try to build it as follows:
"context is already defined in ok()" and "vb is already defined in ok()"
How do I fix this. how do i insert the second value binding expression in the method. any help hugely appreciated. 5DD's
thanks
joe

     ValueBinding vb0, vb1;
        FacesContext context = FacesContext.getCurrentInstance();
     Application ap = context.getApplication();
        vb0 = ap.createValueBinding("#{LoginBean.subject}" );
        Subject subject = (Subject)vb0.getValue(context);
     vb1 = ap.createValueBinding("#{UserGroupBrowserBean.selectedGroupName}");
     vb1.setValue(context, newGroup);Does your bean have proper setter/getter methods for them properties?

Local sharpening with its own sliders

hallo,
is it possible now to make creative sharpening like nx2 and photoshop ?
we have a fantastic detail panel in lr3 and local sharpening was only gain with predefined values given by detail.
i would like to make a capture sharpening with detail panel and a local sharpening with other values of masking, detail and radius
is it now possible ?
like that, for trial images like the one showned in martin evening book (with eye and lines), we could process low frequencies and high frequencies independantly
clarity is nice but different
best regards
marc

Unfortunately no. Lr 4 Beta has the same local sharpening implementation as Lr 3. Often handy, but it does inherit the detail/radius/masking properties from the global settings. (While I can see the utility of having custom ones for local, that would require more substantial changes to how we render local corrections, plus more changes to the UI.)

SelectMany checkbox value-binded with HashMap String,ArrayList

Hello,
Someone can help me please?
Im trying to create a page with a lot of HtmlSelectManyCheckbox, and i need to value-bind then to the same Object in my BackingBean.
First i attemped to bind all HtmlSelectManyCheckbox with a single ArrayList, but only the last SelectMany had their values inserted on the ArrayList...
So, now im trying to bind all the HtmlSelectManyCheckbox with a HashMap<String,ArrayList>, because i would have just one object and for each entry I would have the checkboxes that were cheked in a single HtmlSelectManyCheckbox.
Now my question: there is a way to make this work?
my code example
Backing bean
private HashMap<String, ArrayList> respostaMatrizCheck = new HashMap<String, ArrayList>();
     public HashMap<String, ArrayList> getRespostaMatrizCheck() {
          return respostaMatrizCheck;
     public void setRespostaMatrizCheck(HashMap<String, ArrayList> respostaMatrizCheck) {
          this.respostaMatrizCheck = respostaMatrizCheck;and the bindings
<h:selectManyCheckbox value="#{backingBean.respostaMatrizCheck['1'] }">
<h:selectManyCheckbox value="#{backingBean.respostaMatrizCheck['2'] }">And the error message given when i tryed this is the following:
javax.servlet.ServletException: ValueBinding for UISelectMany must be of type List or Array
Any help would be welcome.
Thanks,
Ferry

Has anybody solved a problem like this? I am facing the same problem and no response helped me so far.
Here is the web code:

     <f:selectItems value="#{categoryController.allLanguagesAsSelectItems}" />
</h:selectManyCheckbox>My backing bean "processor" looks like this:
     public Map<String, List<MyObject>> getLanguages() {
          return languagesMap;
     }(The backing bean has no "setLanguages()-method" since I did not need any with Map<String, String> for example.)
The converter I use creates a "MyObject" instance in its "getAsObject" conversion method.
I think everything should be okay then but the exception I get after submitting the page is:
java.lang.IllegalArgumentException: ValueBinding for UISelectMany must be of type List or Array

How to get the value in a hashmap with a key of expression "123-456"?

Hi all,
I new to java and having a problem with getting values from a hashmap.here is the code which i wrote
Map map = new HashMap();
int m = 123;
int n = 456;
String key = String.valueOf(m) + "-" + String.valueOf(n);
    map.put(key, true);
    Now i am trying to get the value and i get an exception
boolean b = map.get(String.valueOf(m) + "-" + String.valueOf(n));Can someone help me how to pass this expression as key in the hashamp

Hi corlettk,
Thanks for your reply. I have defined my map as Map<String, Boolean> selectedIds = new HashMap<String, Boolean>();
            selectedIds.put("123-456", true);
            int m=123; int n=456;
                                 selectedIds.put(String.valueOf(m) + "-" + String.valueOf(n),true);
            boolean viv = selectedIds.get("String.valueOf(m)-String.valueOf(n)");
            System.out.println(viv);
            My problem is the hashmap key must be set dynamically ("123-456" is just an example) and when i get the value i should be able to pass those varibales in an expression correctly. Please let me know how can i pass an expression like the one above as a hashmap key. Please advise.
