ADFC-00024: no external context could be found.

Hello to all and everyone,

I have a problem in which one of our customers recently met and I'm trying to find and understand the cause.

Here is the error that the client has obtained when browsing through our application: "a connection to the server has failed (status = 500) ''."

So I have moved the AM pooling in order to test the entire application (on WLS server) but could not reproduce the error.

But somehow, when I click on any LOV (Af:inputListOfValues) browser on the page to open and search and selection, I got the following error: "ADFC-00024: No. external context could be found" in my JDev Log messages.

In fact, I got whenever I hit search and I click OK to close the pop-up window (error comes in pair). But the application does not crash even though sometimes I was right and could close the pop-up window by pressing the OK button, the only way to close it then was to use the X button (top right of the popup).

In my view, as two errors that need to be connected. I found people I have both online and said they have changed the maximum Pool size of 1 to 4096 AMShared and it worked. But I don't think that's my answer.



ADFC-00024 is a controller of the ADF error message.

And here's something you can deal with the claim.
I have an af:inputText on the page (id: scanBarcode) and every time the user or triggered anything on the page, the slider should be set to the scanBarcorde text field.

To achieve this, I use an extra controller to the page class.
This controller class implements RegionController and overrides the following method

public boolean refreshRegion (RegionContext regionContext)

I use JDevelopper 11.1.1.6.0.


Can anyone help?

Thanks in advance.

Hi Timo,

Your answer was wise and honest and I am pleased to tell you that the problem is solved.

The problem wasn't the LOV but my regionController class.
So, sometimes (like when I perform a search through the popup Lov) the external environment is not found, and this is the error message I have spoken.
And the external environment is not found because the context faces himself was not.
So what? I added an extra line to my refreshRegion (RegionContext regionContext) public boolean works my codes only when the facesContext is not null.

FacesContext facesCtx = FacesContext.getCurrentInstance ();

If (facesCtx! = null) {}
.. .lines codes

}

This solved my problem (so far).
So, thank you very much for your good and wise advice.

Happy Tuesday.

    OK, so I recommend you test your app on wls integrated with am disabled group. I guess your will see your problem when you try to access the app with more then another user.
    This problem resembles a problem of activation/passvation.

  • Why do I get the "error: no valid source could be found" message when you try to stream video live?

    I'm trying to stream live TV and this message - "error: no valid source could be found" I am on Fox Business website and the message appears in the Fox Business Watch box at the bottom right of the page. I use a MAC with the latest OS. I have another MAC at home and I am able to access streaming content. I can also access the content using Chrome.

    Apparently the old MAC that can stream video has Flash. The new MAC Mini did not have it and I didn't because of the negative things I've heard. Unfortunately, I need on the new computer and downloaded it reluctantly. Problem solved. Thanks for your reply.

  • In Sonic I get the message: no recordable or rewritable device compatible could be found on your system

    No window menu drop-down is displayed when I insert a music CD.

    When I try to open SONIC, it does not open and a window pops up with the following: no recordable or rewritable device compatible could be found on your system.

    This happened after MS fixed a couple of viruses.  The CD will be displayed in the start menu;. Explorer, but no fall to the bottom of the window that appears after you insert the disc.  Sonic will not open and I get the above message.  I can always write to a CD and play them but loss of Sonic is boring.  I have a DELL 2400 PC w / XP Pro 32 bit.  I also have the original sound installation disk.  Help

    Go to the Dell site and download the SoundMax driver.

    I installed on my 2400 of Secunia and Sonic is listed as end of life (no longer supported).

    Also uninstall Sonic.

    I hope this helps.

  • Western Digital USB external hard drive not found by Win XP.

    I have a new USB 2.0 TB WD My Book Essential that my system does not.  I took the first return to BB, thinking it was defective.  A new is similarly, and there is no indication that something is plugged into the USB port.  My system is: 2.8 G P4, 3G of ram, 850 GB on HD 3 internal, under XP SP3.  All 8 USB 2.0 ports work fine on everything else.  My system is well maintained with Virus and Spyware protection and registry cleaning and start cleaning.  Newspaper observer event system is without errors or warnings.  Device Manager reports no problem.

    I tried all the suggestions on bonofan1823 post.  Reinstalled all the drivers and other utilities allowing to scan the USB ports. The drive is formatted NTFS according to WD.  I searched ghosts, 315539 devices. I used the command SFC, 3107747. I ran Microsoft Fix It--I deleted UpperFilters and LowerFilters entries by 925196.

    The WD My Book has its own power supply, all my tensions.  The blue light on the WD drive and it's a small fan is running.  The drive does not appear in disk management or any where.  The icon does not appear on the far right of the taskbar and no audio sound is made when it is plugged into the USB port or powered.

    Someone at - it any other suggestions?  Does anyone else have this problem?

    Thank you.

    Divya R,.

    Thanks for the info.  I've tried the drive on another computer running XP Pro. and it was recognized instantly.

    I found the driver ITS on the website of WD and installed on the computer.  No change, no recognition. WD has also provided a firmware update for the drive that I could not install because he could not find the drive.  I reinstalled the latest version of the BIOS (2005) for the ASUS motherboard.  I used an old record of 250G WD USB years and it still works.

    UPDATE *.

    I bought a $10,00, 3 port USB 2.0 PCI card and plugged.  The WD My Book is instantly recognized and works perfectly. Problem solved.  The problem must be the motherboard ASUS or the BIOS on my P4 system.  I suspect that WD drive information was never getting to Windows XP.

    Thank you

  • All files on external Synology is not found

    Hi guys, I'm not an expert but had been using L6 for a few months and after 2 weeks I wanted to access my files on external Synology but all the files in the module development of break is not found. Strange to me is that in the library, everything seems ok - connection for external hard drive is ok, not smoker of question marks on the folder or files. I can also access Synology from the Finder.

    I had an experience - is installed directly in Lightroom a local folder (on my MacBook) Synology and once he was moved again, I was not able to find these files in the develop module, but again, see the moved folder and the previous file.

    I'm completely confused... running El Captian on MacBook Pro.

    Please help... Thank you!

    Hello! Looks like I've found the bug - the name of the shared folder on the Synology has been notably Polish letter that confuses the relationship between Lightroom and Synology.
    Only, I wonder how it worked before... perhapse Synology update caused the problem.

  • the external context

    Hi all

    Just updated my Design immediately in CS4, which included Dreamweaver. I haven't used Dreamweaver since its beginnings, and it is certainly much improved! Am love him a lot now that I work with her.

    My question... I'm building a fixed/centered layout (@ 970 x), and everything is good (except in IE 6-7, but that's another debate!), but one thing miss me is the creation of what I call the "external environment". By this, I mean the repeating background that surrounds the main content page or a container. I use the attribute 'background' in CSS, but it only works on the main divs, not outside them. I have a div 'all' and then various divs below.

    There are many examples of this kind of background that develops with the display window, a being of these forum pages very (it's the white gray abstract drawing around the main box floating on the left). Another example is:
    http://www.popcap.com
    (this is the illustration of sky blue-green that surrounds the fixed hand, container Center.

    What Miss me? Or is - this bottom * part * of the container principal (and if so, what are its dimensions so that it will extend to all viewers and browsers)?

    Thank you very much for your comments on something which is probably pretty basic, but I seem to be missing somehow.

    There must be a solution out there, but I couldn't find it.  I need to reinstall Office 2007 Suite but cannot because my upgrade discs are looking for a previous installation and of course can't find it.  The version of MS Office, where I have improved in XP has a physically BROKEN DRIVE!  Now what?

    Contact MS Support & see if you can get a free replacement disc, Fern. Without it, you're sunk. See http://support.microsoft.com/kb/326246 (if the earlier version of Office was preinstalled by the OEM, you need to get the replacement on their part.)

    After the release of your lsvol, you have a cassette of cleaning in there, not a piece of medium.

    You must insert a recordable videotape into the library, or to identify correctly this band so this isn't really a bunch of cleaning.

    Thank you
