How to bind inputText 2-1 attribute (for example, area code + phone number)

Hello

Is there an easy way to bind inputText different 2-1 data control attribute?
If not, then is it possible to retrieve the value of * ${bindings.xxxFindAllIterator.currentRow.dataProvider} *?

Hello

Nothing prevents you in linking the two different components to a single attribute, but in this case, only the value entered in the second/later component is taken into consideration (i.e., overrides the value entered in the first inputText component)?
Instead, you can have two different transitional attributes in vo (referring respectively the area code and phone number) and before registration, you can combine and save in the database.

If not, then is it possible to retrieve the value of ${bindings.xxxFindAllIterator.currentRow.dataProvider}?

Yes, you can get

Example Code:

]
 //Inside bean write this code
    /**
     * Method for taking a reference to a JSF binding expression and returning
     * the matching object (or creating it).
     * @param expression EL expression
     * @return Managed object
     */
    public static Object resolveExpression(String expression)
    {
        try
        {
            FacesContext facesContext = getFacesContext();
            Application app = facesContext.getApplication();
            ExpressionFactory elFactory = app.getExpressionFactory();
            ELContext elContext = facesContext.getELContext();
            ValueExpression valueExp =
                elFactory.createValueExpression(elContext, expression, Object.class);
            return valueExp.getValue(elContext);
        }
        catch (Exception e)
        {
           ;// log you message here
        }
        return null;
    }

    //Call the below statement where ever you want to evaluate the EL expression
    resolveExpression("#{bindings.xxxFindAllIterator.currentRow.dataProvider} ")

  • Case: View the balance of the average customer for each area code.

    Hi again together. As a C++ / VB programmer, I used by using a control specified structures like for loops and while loops and use predefined variables to solve my problems. I have a little trouble to adapt to the SQL paradigm, which really does contain a few key words and in built functions.

    I had to have some exercises to do by my tutor at the University, and I have a big enough problem with this one. I to recover the balance of the average customer of a 'customer' entity, but I have to do for each area code, not as a whole. When I look at this problem, I immediately think of loops, conditional check, a variable of integer type to control the loop and possibly a table or a vector data type to store the results. SQL is rather simple, and its simplicity is actually causing me problems, ironically.

    Here is the "Customer" entity which I am to get directions:
    CREATE TABLE CUSTOMER 
    (
                CUS_CODE            NUMERIC(6) 
                CONSTRAINT CUSTOMER_PK PRIMARY KEY,
                CUS_LNAME       varchar(15) NOT NULL,
                CUS_FNAME       varchar(15) NOT NULL,
                CUS_INITIAL     CHAR(1),
                CUS_AREACODE      VARCHAR(3) DEFAULT '02' NOT NULL CHECK(CUS_AREACODE IN ('03','07','08')),
                CUS_PHONE       VARCHAR(8) NOT NULL, 
                CUS_BALANCE     NUMERIC(9,2) DEFAULT 0.00
    );
    I was able to order the customer balances by their area code and to calculate the balances of customers on average as a whole, but as I said I had difficulties to calculate an average of customer balances exactly their area code and do it for all the codes present.

    Any help / example code would be much appreciated.

    OK, so you will understand how to get the average on all clients in SQL, not true? Something like

    SELECT AVG(cus_balance) avg_balance
      FROM customer
    

    If you want to get the average balance by another column, you simply group this column, i.e.

    SELECT cus_areacode, AVG(cus_balance) avg_balance
      FROM customer
     GROUP BY cus_areacode
    

    This essentially tells Oracle to group all data by area code before you run the aggregate function AVG on the cus_balance for each of these groups.

  • How can I stop AutoCorrect on Safari (for example in Web Forms)

    When entering text on my iPad (for example, post on the forums) there are automatic fix strange 'characteristics '. It corrects English in my mother tongue, although I've now added English as second and French as a third language.

    An example:

    "The 6SN7 is one interesting tubes too. Good and beautiful tones. " it becomes "the aan interesting tube 6SJ7's too. God and Nice tones. »

    Allows to leave God out of this please. Replaced words became Dutch. It also replaces 'a' to 'to', in French.

    Is there a missing English vocabulary?

    I presented "Entry text gives errors AutoCorrect on iPad" Apple responds with: "there is no result for your search. Did you mean: enter. Text, gives, autocracy, errors, on iPad? " Autocrazy, Yes, it's a good understanding. (But replace it on my iMac wants to submit to autocracy here too.

    System: iPad Pro. iOS 9.2.1. Safari.

    I found this (in "the iPad Guide"):

    To turn off AutoCorrect:

    1. go to settings-> general-> keyboard

    2 touch (slide)-> auto-correction OFF

    -> A good help function on the iPad would be nice also. Settings does not have such support.

  • How Config Network Service by script? for example the response file

    I created a batch for DB creation using DBCA silent.

    I want to add a script to create also the Networking Service after.

    I was told that it can be done with the answer file.

    Is a response file script also which can be run after the DBCA scripts?

    Where can I find a manual with the available commands so I can produce what I need?

    On the internet, I don't find as silent examples of the DB instalation.

    EDIT

    Operating system is Windows 7 Oracle 11.2.0.1

    I want to create the Network Service that will add these lines to the tsnames.ora.

    DBNAME =

    (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = wsName) (PORT = 1521))

    (CONNECT_DATA =

    (SERVICE_NAME = dbname)

    )

    )

    on the client and the server.
    How can I automatically via a batch script, to add it to the DBCA scripts after creation?

    I was told once to atopic that this could be done via a response file.

    I provided the Correct found answer on this subject since then.

    The 1st solution to set up a NetService via a custom command script, adding the data you need as if it was a BAD IDEA.

    1. you can not guranaty the correct paths if you plan the planting in an API with a lot of end users.

    2. the 1st time, you set up a network service, it must be set to cause netca (network Assistant) 1st the tnsnames.ora is not exiswt at all.

    THE OFFICIAL is to run from a shell in silent mode netca and feed it with values from a response file, either online as parameters

    I copy paste the solution I wrote on a separate thread

    https://forums.Oracle.com/thread/2559659

    The scenario is to set up a typical network Service without using the interface graphics, but instantly with a command from the shell.

    Scenario took place on Oracle 11.2 g on Windows 7

    Level of Description: Noob

    1. you can open of Network Setup Wizard, of the hull directly by entering its name "netca.

    Info: netca is an actaully of batch file calling several "elements". Located in the \bin folder of the directory of Instalation Oracle (Client and server time)

    the patrh of the \bin folder, where is the netca is included in the widnows PATH environment variable. So when you enter netca there and run it.
               https://en.Wikipedia.org/wiki/path _ (variable)

    ATTENTION: If you have the path of the directory before the path of the Client Server, the server netca will run instead

    2. on a typical NetService we re Protocol, host, Port, DatabaseName and the name of the service itself to identify it.

    -Silent option along a response file gives the possibility of is not interact at all with the GUI as all values will be filled with the answer file that will point us

    3. you can find an example of response file to the ORACLE_HOME\inventory\response\ called netca.rsp. It contains all the possible parameters, you can pass, so that you can choose that you need.

    For our scenario, the final answer file will look like this.

    [oracle.net.ca]

    INSTALL_TYPE = ""custom"

    NAMING_METHODS = {"TNSNAMES"}

    NSN_NUMBER = 1

    NSN_NAMES = {'DBNAME'}

    NSN_SERVICE = {'testII"}

    NSN_PROTOCOLS = {'TCP; PCNAME; 1521 "}

    So now you simply enter netca responsefile option along the pat of the answer file with the silent command to power entry

    NETCA/Silent /responsefile /C:\oracle\product\11.2.0\dbhome_1\inventory\response\mynetca.rsp
