How to add values to the Listbox in the ADF.

Hello

I have a listbox that is met when the user clicks an Add button then click on the Add button whenever the values are added.

I have a textbox where the values are added

< af:inputText

label = "Categories".

ID = "itcatg".

contentStyle = "width: 100px".

Binding = "#{viewScope.RegWoComp.CATG}" >

< f: validator binding = "#{bindings." Categories.Validator} "/ >"

< af:autoSuggestBehavior suggestedItems = ' #{bindings. " Categories.suggestedItems} "/ >"

< / af:inputText >

Add a button

"< af:commandImageLink actionListener =" #{viewScope.RegWoComp.btnadd} "icon =" / plusimage.gif "id ="proud"/ >

and you choose a listbox.

< af:selectOneListbox id = "lstcatg" label = 'List of categories' partialTriggers = 'proud '.

value = "#{viewScope.RegWoComp.lstboxcatg}" >

< f: selectItems id = value="#{viewScope.RegWoComp.customList}"/ "lstselect1" >

< / af:selectOneListbox >

managed code the bean to populate the listbox control

The list < SelectItem > customList;

public void setCustomList (list < SelectItem > customList)

{

this.customList = customList;

}

public list < SelectItem > getCustomList()

{

return customList;

}

public void btnadd (ActionEvent actionEvent)

{

customList = new ArrayList < SelectItem > ();

customList.add (new SelectItem (catg.getValue));

}

That's when I click the button remove new value is inserted but the values are not added. I tried to make a method from arraylist and then by calling the Add method, but then also the values are not attached.

This is because you have an initialization list

Declare your list like this

List customList = new ArrayList();

Instead of

List customList;

    Well you do almost everything bad that could be hurt.

    Here is the code that works to insert data into your table (the procedure is not even necessary).

    declare
    p_sl_num NUMBER := 1001;
    p_description VARCHAR2(50) := 'Testing Val1';
    inval1 test_type1 := test_type1();
    inval2 test_type2 := test_type2();
    begin
    inval1.extend();
    inval1(1) := test_object1('testx1', 'testx2', 'testx3');
    inval2.extend();
    inval2(1) := test_object2('testy1', 'testy2', 'testy3');
    
    INSERT INTO test_object_tpe
    (
    sl_num,
    description,
    main_val1,
    main_val2
    )
    VALUES
    (p_sl_num, p_description, inval1, inval2);
    commit;
    end;
    /
    

    See example 5-15 making reference to an element of nested Table Chapter 5 using PL/SQL collections and records in the PL/SQL doc
    http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/Collections.htm#CJABEBEA

    1. you don't even have the procedure because it is a simple INSERTION in the table you can do directly (see my above code)

    inval1(1).val1 := 'testx1';
    

    Since you have not yet created all the elements, there is no element 1 "inval1". You need EXTEND the collection to add an element

    inval1.extend();
    

    And then, there is an empty element, but "inval1" is a container for objects of type 'test_object1' not for scalars as "val1", "val2", and "val3".
    If you can not do

    inval1(1).val1 := 'testx1';
    

    You must create an instance of 'test_object1 '.

    inval1(1) := test_object1('testx1', 'testx2', 'testx3');
    

    And so on for the other collection

    You don't need the procedure (as my code example shows), but once you fill in the variables correctly it will work.

  • How to add programs to the start of the file using Vista

    How to add programs to the start of the file using Vista

    Hi Harry,.

    Oddly enough, you can actually do it in msconfig except if it is already there and simply not checked as opposed to not being do not at all (although you would think that they would understand this option).

    The easiest way is to add the program (or a shortcut to the program) in the folder all Menu Programs Startup.   Here is the procedure: http://www.ehow.com/how_5098465_add-startup-programs.html.  Remember, to do this, you must either a shortcut existing (perhaps on the desktop or elsewhere in the menu all programs) or you need to find the source file (probably somewhere in C:\Program Files depending on what you want to add) and either copy it and add it to the startup folder or right-click on it and create a shortcut to copy into the startup folder.  Once you reboot, this program starts during the initial commissioning process and you will now be able to control using msconfig.exe, if you wish.

    Another option is to do this by using the registry editor.  If you decide to try this, first create a restore AND system restoration point backup of the registry before you begin.  Here is the procedure: http://www.ehow.com/how_7304438_add-program-msconfig-regedit.html.  I recommend to use this ONLY if the previous procedure does not work for some reason any as long as that the procedure is simpler and safer.

    If you want a simpler way to manage and control startup programs, you can try it free WinPatrol http://www.winpatrol.com/download.html that change monitors for startup programs if you set it to run in real-time so that you know when to try new programs are added to your Start menu and, for the purposes of this question includes an Add button which opens a link to a window of Windows Explorer where you can browse the program you want to add, click open to select and then add it directly to the commissioning.  If you prefer it does not work all the time, you can simply uncheck the box which includes this program and it will work only when you choose to run (but at the start, will work as an indication otherwise or configured).  It will appear not in the start menu in all programs (Finally, WinPatrol is, but not programs, it adds to the start), but it will appear in WinPatrol (which also lets you manage what you want or not start with checkboxes as in msconfig) and sure in msconfig - but only after a reboot is complete the process of adding.

    I hope this helps.  Personally, I use WinPatrol myself and let it run in real time.  Since I do a lot of installations, it helped me often prevent the addition of a startup item I haven't really need and reduces how many times I actually need to check what is happening out there.

    If this answers your question without the need to repost in another forum, please mark it as an answer.  If this isn't the case, then of course you must republish as suggested above.

    Good luck!

  • How to assign values to the application points to leave on a table

    Hello

    I have a FORM on a table with two or three elements. How to assign values to the elements of the application with the values in the elements of form, every time the value of the element is entry, change or page is sent?

    I created a dynamic action to the region level with Event - change to run the suite of PL/SQL, I tried with 3 different ways in PL/SQL, as shown below, but it didn't work.

    BEGIN

    : APP_FY: =: P1_FY;

    END;

    BEGIN

    APEX_UTIL. SET_SESSION_STATE ('APP_FY', v ('P1_FY'));

    : APP_FY: =: P1_FY;

    END;

    BEGIN

    APEX_UTIL. SET_SESSION_STATE ('APP_FY', v: P1_FY);

    END;

    Then I created an action dynamic at the ITEM level with change event to run the suite of PL/SQL and tried with PL/SQL, as shown below, but it didn't work.

    I need to assign values to the elements of the request form as these elements of the application will be used in many other pages in the application. How to I get there?

    Thank you.

    If a dynamic action of PL/SQL execution, you must send your list of page elements in the parameter "Elements of Page to submit.

    See the section 'run pl/sql' for this post.

    If the page is submitted, the elements of the page will be automatically set to session state, and you can have a page process make the code you have.

  • How to add text to the file selected?

    I have already updated title but I don't know how to add it to the selected real file (the one in the middle)... I read on some other forums but its still confuse me.  Also, is there anyway to add the effect of movement, as drag in or dissolve almost?

    Screen Shot 2016-02-19 at 10.27.40 PM.png

    I mean this in the nicest way possible, but it's very wacky workspace you put in place there. Create titles is muuuuch easier in the standard workspace Edition. When you create / open a title in the editing workspace, he creates a floating large window with the title of all the members of panels. It is about the only time I am ok with windows in the first floating. You will create the title in the window title, and then close the window title entirely. The video for the title will then be in your project Panel (which you can not common to see in your current workspace configuration, but will be very apparent in the workspace standard edition in the lower left). So the best thing to do is to simply drag the title element of the project to sequence Panel (another Panel today, you don't see in your current workspace arrangement.

  • How to transfer values to the popup while the bean in application scope?

    Hi all

    I use JDeveloper 11.1.1.4

    My scenario is that I have a < af:popup > with a component of < af:outputText >.

    I need pass values of output text dynamically according to the scenarios.

    My grain of support is application scope . So I'm not able to pass values using get and methods.

    My Design as,

    < af:popup id = "p1" contentDelivery = "lazyUncached" >

    < af:outputText value = "#{managedBean.getDynamicText}" id = "ot1" / > "

    < / af:popup >

    Now I run the application I'm not get all values in text during debugging output, I am able to set the value, but it didn't reflect on the page.

    How to transfer values to the popup while the bean in application scope?

    Thank you...

    At the bean, why don't you set the value to a variable pageflowscope and point the outputtext popup to the pageflowscope variable?

    () .getpageflowscope, set AdfFacesContext.getCurrentInstance ("nomvar", value);

Can I use an array to store the 'total '? I try to use register to shift and it gives me only the current number and the previous, i.e. I get 2 whenever I'm doing a count.

    If you want just a number, a scalar value must be what you put in the shift register, not a table.
