How to set the session bean of backing bean variable

Hi all -

I have a bean with a session variable and I want to set the value of this variable to a bean of support. Could someone please suggest how to achieve this.

I use ADF 11 g.

Greetings-
Rohit

Hello

First of all, you need get the referral of bean in the bean to support session, and call the method that sets the value of the attribute. Getting session bean reference - you can use dependency injection, which is the best way, but you must register your bean in faces-config. XML (not adfc - config.xml, see http://biemond.blogspot.com/2010/04/ejb-injection-in-jsf-managed-bean.html).
An alternative is to search the session bean's JNDI.
Third option involves data controls: you create a session bean data control and then expose the method to fix your attribute value, in the calling page to jspx pageDef. To do this, you can't use method that begins with 'set', because you will not be able to exhibit in the pageDef (at least not with the Visual Editor). Then, you can call this method from the bean to support using this code:

        BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
        OperationBinding operationBinding = bindings.getOperationBinding("yourSessionBeanMethodExposedInPageDef");
        operationBinding.execute();

I hope this helps.

  • How to set the session value to field item?

    Problem: The table insert source column is different from the column I get data for the update. I assign session by a process during extraction value but this value does not get assigned to the field. ?? Can someone give me a solution to this?
    Thank you

    Hello

    When the extraction process runs while recording for the form, it will use the values that exist in the folder, thus crushing any value you defined in the session.

    One thing you could try...

    1 create an element of application - through shared components - called, say, G_DEFAULT_VALUE
    2. on the page element that needs this value, type: G_DEFAULT_VALUE in the parameter of calculation calculation Post
    3 - instead of set point on page in your process/calculation, the value of the element of the application instead

    Then, regardless of the value on the record, the value of the application element is used instead. If this is not required in all cases, set the application to null element and use the following options for the calculation of calculation of post parameter:

    NVL (: G_DEFAULT_VALUE,: PAGEITEMNAME)

    Then, if the application element is null, the value of the page element (that is to say, the value of the record) will be used instead.

    Hello
    Is it possible to output report to the session variable value. If my report returns 1 row and 1 column.

    I have a dashboard command prompt where I select name, but I want to find the ID of the same name.
    This ID I want to move to a Fx column, to achieve this, I created an interim report and I got the code. Now my problem is how do I put this ID in the session variable.

    If you have dashboard guest (name), then you can have that one report that is filtered by a name but present card to display or not id but use id in the service. Or two reports as in the solution in the second link above and the second report has id in the function and filter by the id of the first report. You need not define this ID in the session for this example variable.

    Federico

    I would like to know what is the right place/method to set a deadline.

    For java web applications, you can set the session timeout in the web.xml file. (this is the global settings associated with all sessions)

    If you wish, you can set the timeout of session by program (and this is related only to the current http session).

    If possible I would like that when the timeout checks, the application performs a redirect to a page I like (for example the login page).

  • How to set the value of a field from the LOV of another field.

    I'm trying to figure out how to set the value of a field (P_PROGRAM) to the value of another field of based lov (P_STATE).

    The P_PROGRAM field is a hidden field. The P_STATE field is a required field and is based on a list of values for the State Codes.

    When a user selects the State to P_STATE, the field of the P_PROGRAM should be set to this value, as well.

    I tried different ways to get there via a function call on the post for the calculation of the field P_STATE, defining the source P_PROGRAM to the value of the page item P_STATE put varialbles, creating a process before SENDING, and they all still come back as having a NULL value for P_PROGRAM, therefore impossible to create the file in the db as the PROGRAM is a mandatory field in the table.

    Can you please help? Thank you, Laura

    Laura,

    It is always helpful if you provide information about the Apex version you are using. The Apex 4 you can use Dynamic Actions to achieve this. In earlier versions is possible using processes to submit or javacsripts, as well.

    Heres how you do in 3.x with treatment to submit, to make it work in 4.0 as well.

    1 do the P_STATE ' select list submits the Page.
    2. Add a calculation on the point P_PROGRAM, or write to him assign a value based on a process. The treatment should be OnLoad after the header
    3. If the page does not have an unconditional branch that loops on itself, add a. NOTE: The direction must be the last branch (larger sequence number) and should have checked "Save Session State".

    This is what will happen
    a. when the State is selected Page will be submitted
    (b) it will take the unconditional branch to himself and save the value of P_STATE
    c. the calculation process / fills the value of the P_PROGRAM element when the page reloads

  • Documaker: How to set the overflow by page 2

    Hi Experts,

    I want to put the overflow of 2 per page.
    Overflow works, but a part of the production is superimposed on 1 page.
    I can't set the overflow by 2 pages?

    1 formA (contains Subform1)
    2 Subform1 (contains Subform2)
    3 Subform2

    Subform2 has 2 pages (pages 1/2).

    Subform1 on proforma is the overflow setting when the trigger by XML.
    Search mask (counter)!: / xxx, data, repetition, repetition

    Subform2 on Subform1 offers which are always repeated 3 times.
    Reference:
    Documaker: How to define repeated 3 times exceeding always.

    For example, there are 2 types (Type 'X', type there "") in "Repeat".
    In the test, sample output is as follows.
    I want 12 pages output, but output data are 11 pages because PAGE 6 superimposes itself on 1 page.
    (1), (2), (3) East County. (Always 3 times a 'Repeat')

    PAGE 1: TypeX (1) - page1
    PAGE 2: TypeX (1) - page 2
    PAGE 3: TypeX (2) - page 1
    PAGE 4: TypeX (2) - page 2
    PAGE 5: TypeX (3) - page 1
    PAGE 6: TypeX (3) - page2 is encroaching TypeY (1) - page1
    PAGE 7: Typical (1) - page 2
    PAGE 8: Typed (2) - page 1
    PAGE 9: Typed (2) - page 2
    PAGE 10: Typed (3) - page 1
    PAGE 11: Typed (3) - page 2

    Please tell us how to set the overflow by page 2.

    Thank you

    It always seems that you have your typed page (1) configured to use an absolute origin and defined on the same page as your another subform.
    If your know you will have to TypeX and typed elements and you want the TypeY to start on a new page, then you must go back to the provision of origin in DMStudio and create a new page and start the subform to TypeY on its own page.
    By definiing two subforms on the same page of the form and each giving origin start to ABS 0, you say that the two elements can co-exist on the same page. That might be true if they are mutually exclusive where you would have only one or the other. But if you can have both, you can't have the second subform have an absolute origin. Otherwise, he will always overlap all that exists on the page where you set trigger.

  • How to set the render property of the field on one facet of panelSplitter?

    Hi, experts,
    In jdev 11.1.2.3,.
    How to set the render property of the field on one facet of panelSplitter?
    -If the panelSplitter is reduced then make some fields in the second pane. otherwise, do not make these fields.

    It is not an easy job for me to set the EL expression.
    Thank you.

    OK, just did a small test case. It turns out that the difficulty is to automatically update the fields when the separator discloses. To add a pair of earphone client/server. This sends the event to disclose to the bean to update the fields.
    Page code:

    

  
  
    
      
        function disclosePanelSplitter( event) {
            var inputComp = event.getSource();
            AdfCustomEvent.queue(inputComp, "myDiscloseEvent",
            {}, true);
        }

    and the corresponding bean to the scope of the request

    package de.hahn.xyzxyz.view.panelsplitter;

import oracle.adf.view.rich.component.rich.layout.RichPanelSplitter;
import oracle.adf.view.rich.context.AdfFacesContext;

  • How to set the LOV when in a pop up

    Hello!!!

    We work with ADF 11 g and the user wants to use a LOV a field during their research and another when they change the information in a pop-.

    I have the popup work and we may change the information but I can't understand how to have a different of LOV show when the user is in the pop-.

    I've set the attribute VO use 2 LOV and I added a transitional attribute to the VO and picked up as a list of value switch but I can't figure out how to set the transient attribute when the pop-up opens
    so that it will use the 2nd LOV while in the pop-up etc and then together is back to normal when they are not on the shortcut menu.

    Everyone comes through this?

    Thanks in advance.

    The best solution I found for this was using two different views and then link them. This allows a different LOV will basically be attributed for the same attribute. Be sure to use the correct view on the specific form for the desired LOV.
