[ADF, JDev12.1.3] viewScope bean can not recover sessionScope bean. Why? (How to day uploading of a session bean scope whenever a page with params is called)

Hallo,

to the login page of my application, I created a viewScope managed bean loginView.

In the login page, I put a "dummy" inputText (whose value is related to dummyInitEditValue bean attr) to perform lazy loading of the page itself.

In the initData() function I call a function of a bean sessionScope connection which should initlialize some of its attributes.

public class LoginView {
  private Integer dummyInitEditValue;

  public LoginView() {
  }

  private void initData() {
    Login loginBean = (Login) FacesUtils.getManagedBeanInSession("login"); // loginBean = null !!!
    loginBean.initData();
    dummyInitEditValue = 1;
  }

  public void setDummyInitEditValue(Integer dummyInitEditValue) {
    this.dummyInitEditValue = dummyInitEditValue;
  }

  public Integer getDummyInitEditValue() {
    // Per lazy loading
    if (dummyInitEditValue == null)
      initData();
    return dummyInitEditValue;
  }
}

The problem is that the initData() rises a null pointer exception because the bean connection is not found.

What's not in my approach?

I create this hoping to resolve this issue: the login page has 2 URL parameters (defined in his point of view in the config.xml file - adfc) and I have according to them I need to update some of the bean sessionScope uploading connection every time the page is called / refreshes (possibly with new values for the parameters).

BdW I do not know if there is a better alternative you can advice me.

Thank you

Federico

Well, you need to instantiate bean connection somehow.

You can try to link an attribute of connection bean to the page and see if this will help or you can try to resolve expression programmatically (something like #{connection}).

Or you can try adding session bean defined as managed property for your bean view extended (something like this: http://umeshagarwal24.blogspot.ba/2012/09/using-managed-property-to-evaluate.html).

    Hello Marilyn,.

    Welcome to the Microsoft community!

    You cannot access the AuntiM4, get the message incorrect password and when you try to connect with Microsoft ID, you are redirected to another page.

    The problem may occur if there is a malicious content or if the hosts file is damaged.

    1. the problem occur only when you access the AuntiM4?

    2 did you do changes on the computer before the show?

    To check if the problem is due to malicious content or corruption of the hosts file, I suggest you follow the mentioned steps:

    Method 1:

Reset the Internet Explorer settings can also reset parental control settings. We recommend that you note these sites before you use the reset Internet Explorer settings.

    Method 2: Reset the Hosts file

  • Can not recover my laptop using created recovery disks

    My hard drive crashed, I sent it to the warranty. She came back, but I wanted to reinstall.
    Before that, I did 4 recovery disks.

    Thus, when the laptop turned on DISC 1 was in and I could choose Windows 64, after a while he told me to put in the next disc. I did but no progress. I tried all the disks and none of them worked.

    How should I proceed from here?

    Unfortunately you can not force the installation of recovery to work. Either it works or not.
    Are you using these discs for the first time now?

    By the way: what model of laptop do you have?

  • Can not recover the Windows 7 desktop after replacing the hard drive

    I bought a new HP Pavillion Elite (HPE-240f) in August 2010. A week ago my hard drive has no SMART short self-test during systematic hardware diagnostics. I installed a new hard drive of the same size - 1 TB and could never make it work properly. I tried the following (in that order).

    1. using a system repair disc, I got the system from a previous image (which I did shortly after the purchase, install my own software and configuration of all). It worked, but then I noticed that Windows Update was not working. I ran various Microsoft diagnostic tools and discovered that some (unspecified) system files have been damaged or missing. All the fixes I tried didn't work. I ran hardware diagnostics extended, but no problem not found.

    2. I tried to restore the system to the default settings by using the original image on the D partition. At first it seemed to work, but at the last moment when the system started, I saw a message on the screen that Setup is starting services and then got a warning saying that services failed because of (unspecified) problems with hardware.

    3. I tried to restore the system from the system recovery discs and a message "system recovery disks do not support this computer."

    4. I found this Cyberlink utility on the HP website, dealing with precisely this issue. I created a CD tried and it didn't work.

    5. I found this document on the HP Web site, saying that if you are replacing a hard drive with sectors of 512 bytes with a new advanced Format (AF) drive (with areas of 4 096 bytes) and your system was manufactured before October 2010 (as mine was), you must get the new HP recovery disks. I thought I finally found the root of my problems (since the new drive is indeed AF and the old man is not) and ordered HP recovery discs.

    6. the disks arrived today, and I noticed that the version number of the software (for Windows 7 version) is almost the same as on the computer, except that the last digit is 9 on disks and 6 on the computer - I guess it's an update to deal with the problem hard drive AF. However, I get 'system recovery disks do not support this computer' error, if I use the utility from CyberLink recovery disks or not. To be on the safe side, I even used a new hard disc (new 1 TB) right out of the box (never partioned and installed previously) and connected the original keyboard supplied with the computer (I also unplugged everything except the monitor, keyboard and mouse). However, I get the same message. Just out of curiosity I tried to put back the original hard drive (certainly not in best shape, even if the system always starts with him) and still could not recover the system.

    What else can I try?

    Any help will be greatly appreciated.

    An alternative to try. > If you can read the Microsoft Windows 7 of 25-character license key attached to the Tower, you can download a Windows 7 ISO file to burn to a DVD. The version must match that on the sticker COST Microsoft. for example Home Premium

     

  • Can not recover my system after a hard disk crash.

    Hello

    Hard drive of my hp DV6-3123tx crashed due to a collision

    The steps I did:

    1. Got a new hard drive and put it on.
    2. Via recovery DVD tried to format it.
    3. Everything was good, but when you restart the system to install the drivers it gets stuck only on the first page (on which hp is written). I waited for hours together, but it is not recover from this State

    PS: I had deleted CMOS too after my hard drive crashed, but restored and saved its default settings in the BIOS before the steps mentioned above.

    Go to the link below and you can order to reinstall HP discs. What they charge is approximately US $15 for shipping and handling.

    1. If it is the domain controller, you cannot change the name of the computer by selecting network ID and this is normal.
    2. If it is a member of the computer in domain or workgroup, you don't have permission to change the name of the computer.

  • New hard drive installed Vista Ultimate, now I can not install my printer - why?

    Computer Dell laptop hard drive replaced (warranty) with Vista Ultimate, I installed Office 2007 Professional disc 1 fine, windows update is fine, but I cannot complete the installation for my Kodak printer disc. Has been given the Internet to install via the internet address - link doesn't work either - drive flashing green bar "installation preparation" then nothing? Link Web shows 'Preparing to install' with a full bar green - then stuck there. A few minutes later, he disappears. Never installed. Do not open the drive or cross the bar - never open the Green window to install. Support Kodak decided that I was missing the .net on pre-installed OS HDD framework files. Enough of 3.45 and 4. Is this correct? Do I need previous versions, or something else is the cause. How can I check to see that all the files are correct and understand WHY I can not INSTALL MY PRINTER?

    Until the hard disk, memory & the keyboard have been replaced by the Dell tech, I had installed and printed on this Kodak printer for 9-12 months. Suggestions welcome.

    Hi LSMama,

    (1) you get an error message?

    (2) what is the model number of your printer?

    There could be several causes for this problem, try the following steps:

    Step 1: Run the troubleshooter printer available in the link below and then check

    Solve printer problems

    Step 2:  Clean boot the computer and then try to install the printer
