Deployment of HAProxy and ADF gives problem with validation

The problem:

On pages with forms that are used to populate a newly created line, all postings are triggered on the loading of the page with the result of messages for all the fields on the page until the user can start filling out the forms. This only happens behind the loadbalancer when deployment directly accessing everything seems to work.

When I say on the loading of the page, it isn't exactly on the loading of the page. Loading of the page and everything seems fine for a fraction of a second. However another application is launched and all validations are triggered. This request comes with and without loadbalancer. But it is only with validation when behind the loadbalancer.

The case:

1. create taskflow who in a method call, creates a new record and in a second time, show a form for this new line

2. create a jsf page that contains a box with A taskflow

(If you come from a page that has already initiated AOS error happens again here)

3. create taskflow B which is the same thing has to another VO, call taskflow taskflow A B.

Work half workaround solutions:

The only solution that seems to work a bit is to ensure that the form is the first page that launches a module of the application (or something vaguely akin to that?). But this still does not work, I need to look for it further how this affects exactly the problem.

Refresh the browser window allows the validation of messages disappear.

Defining field validations triggers only immediate so that fields of all other fields are triggered is no longer (at least on the page load)

The environment:

HAProxy Loadbalancer

ADF 11.1.2.3

WebLogic 10.3.6.0

I also logged a service request: 3-9991555971

Configuration of the HAProxy

Any advise on HAProxy configuration or how to debug this issue is welcome.

It seems that the problem is that some settings in the HAProxy removed the header "oracle.adf.view.rich.STOP_ACTIVE_DATA". When this header was not there he causes the phases 2 & 3 to be carried out for a bunch of requests and that lead to the postings. All the other things mentioned seem to be a coincidence.

  • I use an analog input on a PCI-6224 and are having problems with the clock source

    I use an analog input on a PCI-6224 and are having problems with the clock source. I'm trying samples of 16 different analog inputs very quickly. I have the sample mode: Timed Single Point material. The rate, that I am running is the maximum (250 kHz (15625Hz per channel)). I left the default clock source and trying to taste several times. The analogue input works for a short time (2-3 seconds) and then everything stops. I'm doing something wrong or is there something I'm missing? Any advice would be great.

    That's how you samples using the sample clock clock. If you see a delay then something is wrong with how you track/data visualization.

  • After 3 years of use of this helmet and having no problems with it, now I can hear the sound in the right ear

    Hello, after 3 years of use of this helmet and having no problems with it, now I can hear the sound in the right ear... what should I do? Help, I don't want to say 'goodbye' to it already... Thank you

    It could be the plug on the computer that is the cause of the problem. Try another helmet or a pair of speakers in it.

    If you hear only on one side, who will tell you that is the question.

    If you hear from both sides, you must obtain a new helmet

  • E4200 w 2 - re1000 and still have problems with wireless coverage

    I have a big enough House, 4500 square feet, and there a lot of bricks and stucko.  I wired ethernet ports in most of the rooms.

    For my Apple TV and tower PC, PS3, I used a wired connections.

    But we have a lot of devices without wireless, 4 laptops and 3 iphones, 3 ipads so good wireless coverage is a must.  I'm not looking for a budget solution, just the best solution that I can.  I also have a wireless baby monitor and an ATT Wireless TV receiver.  I have no end of problems with wireless on my devices.

    Without a lot of research I boght a couple re1000 thought that would be the solution to my problem, but they don't really work as well as I would like.  I wish I had done my research as I think that the right solution is to have the other AP in the connection from the House to a 'hand' AP via wired connection (connection wired bridge mode?).  I could adjust only force and channel to maximize coverage for the House.

    Here is what is a must:

    One SSID in the House

    Everything must be on the same network.  I have a wired camera Foscam and use the features of the homegroup in windows.

    Taking as a basis the e4200, what other should AP I buy to connect to the main via a wired connection?

    I don't know how to close your home is to other houses, so I don't know if you might encounter interference from 2.4 ghz to your neighbors or other sources.

    I see that WAP610 is not simultaneous... only selectable.  iPhones are only 2.4 ghz

    Whatever it is, you can keep the same SSID for your entire network, but you may need to use different wireless channels.  Everything meets your criteria above.

    The only unknown is your neighbors (and other sources) Wireless interference.

    You can download inSSIDer, which will give you a better idea of what you're against, but it is not infallible.

  • I got a phone call from a benny edwards who said Microsoft and had found problems with my computer.

    * Original title: defraud my computer

    I got a phone call from a benny edwards who said Microsoft had found problems with my computer and the pirates had gotten him. As I have had some problems recently with the computer, I thought it was authentic and fell for it? After a long telephone conversation, he forced me to accept that my Bullguard anti virus and my malware Remover is not enough to protect the computer and forced me to buy a program from Microsoft (this man of course) not microsoft. It supports the remote computer, and then forced me to give him my details, name, address, telephone number and age and of course the fool that I am, my credit card number, the penny dropped when he asked the Envoy of money via western union.  When I told her that I was closing the phone call, he told fort and wiped a number of things from my computer, the computer wasn't sure.  I ran my scanner (twice) bullguard, run my anti malware program, changed my password and order my credit card, is there something more I can do?

    To protect yourself, your information and your PC, follow these steps:

    • Change your computer password, change the password on your main email account and change the password for all accounts, including your Bank and credit.
    • Immediately scan your PC with the Microsoft Security Scanner to see if you have the tools malicious/phishing software installed on your PC.
    • As a third step, I recommend that you run the verification of Security Essentials on this page. The check will ensure that the security features in Windows are normally very active and running.
    • Personally, I have a clean Windows installation, because something could have been tampered with.

  • Since the installation of Mac Mavericks all my friends with Macs and I have problems with the cursor disappears, that in Firefox, Safari is very good...

    I stopped using Firefox as nothing I've done has corrected this problem. I tried to close Firefox and restart it, I erased all my Add-ons and then added adblock back (it's the only one), but it still does not work. I deleted files so that I have more space - I can't think of anything that works. I talked to four of my friends with Macs and they are all having the same problem with Firefox since the Mavericks.

    Cursor disappears huh? It's quite strange. All of the compatibility of the Mavericks can be followed in [Bug 883824]

    Try this work around:

    1. Go to Firefox > Preferences > advanced > general
    2. Always check "use the cursor keys to navigate through the pages.

  • El Capitan 10.11.4. is safe to put up-to-date and not having problems with Adobe Creative Suite?

    I read a lot of problems with the update of the system of El Capitan, the thought of updating scares me. I use Adobe Creative Suite to work, so it is crucial for me that they work perfectly together. Resolved bugs in 10.11.4?

    Every single major and the Mac OS update brings out the horror stories. Which most is caused by systems that are stuck with rubbish like AV software applications Or really worthless, damaging as CleanMyMac, MacKeeper and other apps that garbage (haxies).

    The only real issue I've seen in El Capitan, which was specifically a problem known BONES was that placing old types of fonts directly in the folder/Library/Fonts /, or their activation in place with any font manager would not work. They had to be put into the folder of the user account or activated as a collected police policies. Which has been fixed in 10.11.3.

    Otherwise, I use most of the CC apps every day (primarily Photoshop). Everything works as expected.

  • Hi I'm new to all this, and I have problems with an update,

Please help me I'm confused!

    Hi kiajoe,

    (a) what messenger do you use?

    (b) the question (the Messenger) took place right after that you got the error code?

    Microsoft lifecam vx-1000 installs automatically without extra software, so I don't think it's a driver problem.

    If you receive the error Windows Update 8024000, it means that Windows Update is unable to read a file (update manifest) that is required for installation.

    To resolve this issue, follow these steps:

    1. click on the button to start the picture of the Start button, type run in the start search box, and then, in the results list, click Run.

    2 copy the following text, and then paste it into the text box run:
    Cmd /c %systemroot%\System32\Spupdsvc.exe Spupdsvc.old ren

    3. click on OK.

    4. run Windows Update again.

    Check if the problem with your Messenger continues once you have solved the problem of error code Windows Update.

    OK, here's my problem. I had Windows Vista, has been sick with it. I'm not used to ask someone if I can or can not install some software or OS, so I have two formatted partitions (recovery hp too) and installed windows 7 now, I discovered that he had a lot of problems with the drivers. I have successfully resolved all of them, even my hp legacy works and everything else, except the driver Nvidia. My screen resolution is 1024 x 768 and should be 1280 x 800. I tried all the drivers that are provided in the topic above here (dv6000 - dv9000 update for Win 7 or something like that) also downloaded and installed this driver "179.48_notebook_winvista_win7_32bit_beta", nothing helps worked on this problem for 2 days, am tired and ask for help I need resolution 1280 x 800 on my screen , and I now have 1024 x 768.

    Dan or one of the others may be able to help if you post exactly what indicates the error.

    As you say you are not a noob so maybe you need to change something in the NVIDIA Control Panel. Maybe go to the advanced option when you're at NVIDIA.

    Personally when I clean installs I delete, and format the entire disk before installing W7. Doing it this way usually prevents this kind of error occurs. When you use the W7 install disk to format, it may not remove all of the old files registry Vista and can cause problems.

    If you start from scratch once again, this may solve your problem, but there is no guarantee.

    It took 4 tries on my HDX from Vista to W7 to do things.

    I just took a glance at my NVIDIA advanced and under Show options there is an option to "manage custom resolutions. Here I could input what I wanted. What's your has that?

  • I am on my second computer with display 4 k and have major problems with lightroom and photoshop crash windows 10

    During a photo this morning montage, photoshop crashed and restarted ten windows.  He did whenever I opened it.  I had to uninstall lightroom and photoshop to stop the problem.  I had this problem with another laptop.  I'm think he had back problems.  Now, I have the same problem on this news.  I don't know what to do, but it drives me crazy.

    Applications can have all of the computer of BSOD, stop, restart, or gel.

    The only things that can cause that are bugs in the operating system, bug in the drivers at the low level and the defective material.

    If you have a Nvidia GPUS with Nvidia to see if you can use their beta driver or if you need an older driver to correct their recent driver bug that causes errors in kernel_security_check.
