Implementation of collapsible list, cannot set field

Hello

I implement foldable list by using managers and field:

-When the cell is developed, a data provider returns a list of the fields to add as the child cells, and they are inserted into the vertical field Manager.

-When the cell is reduced, the child fields are removed from the Manager of the vertical.

-The data provider is fetch field on the web properties, so it is an asynchronous process

Everything works well except:

-For the passage to the next screen and back n trying to expand, collapse of the cells, the JDE console says:

WARNING cannot field layot, insufficient height or width

And new fields are added to the Manager of you but not drawn on the screen

Help, please

Thank you very much

Sorry for reply late cos I was on vacation.

My problem is solved without changing the code of the user interface (my managers already had vertical scrolling properties) defined.

The problem was related to the operation of the network and the listeners.

Sorry for the confusion.

Although every thing is good, but I always get warnings and I don't know why.

Thanks again.

    The graphics card hardware support different screen resolutions, but if the driver doesn't contain this resolution of the screen so that you cannot choose it.
    I think so you re not able to choose this special resolution on the external display.

    In my opinion it has nothing to do with the graphics card or with the screen, but only with the graphics driver.

  • RN314 cannot set up alerts

    Just I have an open for this support ticket and I'm getting nowhere fast at the moment, while the community has been so useful until now I was wondering if someone here could help/advise.

    -For the NASs x RN31400 2 I am owner and you have registered with you I am unable to setup e-mail alerts. I tried to use 3 e-mail addresses of 3 service providers: Yahoo, Hotmail/Outlook and also my own ISP TalkTalk email providers.

On one of the RN31400s using Yahoo worked initially and the alert section would say that it has been configured correctly and I'd get emails to my 2 hotmail addresses, it was on 1 of my RN31400s on the other RN31400 the settings would save not and always say, there was a problem but I had managed through test messages. Now, no matter what settings I use, which email provider I use, etc. I can't e-mail job alerts! Please help because this is obviously a problem with the NASs and the software on devices, the version of the firmware on two is 6.4.1 Ive set up the addresses of 3 E-mail on an e-mail within my network client and all 3 work well, the 3 x NV + s do not have a problem using my Yahoo account to send alerts check my routers and firewalls there is no blocked traffic and I can't telnet to Server 3 Messaging without problems. Please advise/help, thanks.

    Hello

    Just right now I can read the KB article - which does not help somehow:
    KB.Netgear.com/app/Answers/Detail/A_ID/23066

    There is nothing wrong with the configurations that I use.

    All 3 servers SMTP and the above settings work very well on my NAS NV +.

    All 3 servers SMTP and the above settings work fine on Outlook or Mozilla Thunderbird's within my network.

    All servers SMTP 3 and address listed above work fine when I Telnet to them within my network.

    First settings of Yahoo SMTP worked well on one of the RN314 and seemed saved and ok.

    Also...

    At the beginning of Yahoo SMTP settings worked well on one of the RN314 but not record or say that it has been configured correctly.

    Then obviously there is something wrong with the SMTP service/server on these NAS RN314 2 bed.

    I am not willing to allow you access as it will provide no benefit whatsoever.

    For the course of 20 years, so it's nothing that can be done with you giving remote access with the exception of confirm you what I have already said previously, I have worked in it.

    And...

    So please advise what Netgear will do then or advise what other other confirming my settings allow remote access?

    Your forums to research it seems that problems with mail like this are apparently quite common, so what has already been done to solve the problem?

    Also the error code: Code: 5008010002 error msmtp

    Why you are not this survey with your development teams who wrote the OS on the NAS working on what actually the error means?

    There is nothing wrong with the configuration that it works very well on my 3 x NV + NAS, it works very well in e-mail clients, it works very well in Telnet, and it worked very briefly on the 2 x RN314 of for of Yahoo SMTP settings.

    Eron - if you are unable to help further please add this problem to your support line... 3rd line?

    Thank you.

    And...

    If this does not work on the RN314 but it works very well on the NV + of via Telnet and in an email client (x 2)

    Please escalate to your next level of support, thank you.

    Right, I have fixed on one of the RN314 far...

    I backed up all my data on this RN314 and did a factory default.

    I have reproduced the RN314 settings manually then nonworking time for the reset RN314 except for identification data, i.e., name, etc.

    Exactly as it was before... and now the RN314 in default works fine.

    I am currently backing up the data on the RN314 now inactive to perform a Setup factory on that one and see if that solves the problem on this one here.

    Then we can close this and I will refer to it with a new thread if I need if the second RN314 still has problems after the default settings.

  • Error: The installer cannot set Windows XP required configuration information during the upgrade to Windows XP Home SP3 of Windows XP Pro.

    Original title: OEM Windows XP Home SP3 update XP Pro

    Here is a compilation of the messages from another forum regarding
    My problem:
    ---------------------------------------------------------------

    I'm trying to upgrade a Windows XP Home Sp3 OEM system to
    Windows XP Pro. (There are a few Pro features
    that are not available in the House I now need: (1) the files offline and
    (2) an add-on available for free to Onenote 2007, Top2onenote, requires a Pro).
    I don't want a clean install, but an upgrade. I bought a Windows XP Pro
    Upgrade CD on Ebay that was Windows XP Pro
    Gold (v2002). I'm sure that's true for the following reasons:

    It has been listed as an upgrade, but the CD is not labeled "Upgrade".
    It seems very authentic with all Microsoft holography.
    He came in the standard package of Windows XP (without box),
    and it was sealed.
    The name of volume for the CD is WXPFPP_EN. The Internet,.
    It is the retail of Windows XP Pro RTM (gold)!

    Here are things I tried initially.

    (1) I tried to upgrade to Pro from the purchased CD. It is immediately
    has refused to upgrade indicating the upgrade OS (Pro) is older than the
    installed OS (home)...

    (2) I read about "slipstreaming". "Slipstreaming" allows to integrate
    a service pack with an earlier version of the operating system. I created a
    upgrade XP Pro SP3 with Nlite slipstreamed CD image (and
    Autostreamer later, but it made no difference) from the purchased CD
    and a file containing SP3.

    After you burn the CD and start the upgrade
    (Windows installation), the upgrade process
    product through "information collection."
    "Dynamic update" and "Preparation of Installation" with
    no problems. My computer restarted and returned to
    "Installation preparation". A progress bar called 'Progress '.
    quickly filled to about 90% and the hanging system
    at that time there for about 15 minutes.
    Then, I got the following error message:

    Setup cannot set the required Windows XP configuration
    information. This indicates an internal Setup error.

    This is where I am stuck. I had to leave the installation at this point.
    My drive is starts raining and I had to restore a backup.

    (3) just for the heck of it, I formatted my hard drive and
    reinstalled my original OEM XP Home SP3 OS (no clean up, no user file).
    I immediately used my XP CD slipstreamed Pro to try one
    upgrade to XP Pro and IT WORKED! I need to find out why the
    properly clean XP Home OS upgraded to XP Pro but my pre-existing
    (with the files users, drivers, etc..) XP Home OS does not level
    successfully to XP Pro.
    -------------------------------------------------------------

    Another post:

    Yet once, today, I installed a new copy of OEM Windows XP Home Sp3.
    I continue with installation of all the essential and the add-on
    pilots (essentially all my original version). Then, I
    set up a network connection and firewall. With this configuration,.
    I ran the Pro XP slipstreamed SP3 CD. The upgrade to XP Pro
    success (even if the upgrade not configured my graphics
    card properly). I guess my current problem is either the registry,
    the WINDOWS, some user file or parameter file.
    ---------------------------------------------------------------

    Another post:

    I made a file and the backup of the folder C:\Windows folder
    on my system that is pre-existing (OEM XP Home Sp3). I also did a
    separate the backup the State of the 'system' on my pre-existing system.
    These are added my full image backup of her pre-existing
    system a month ago.

    I did a backup image of my system (minimum fees OEM XP Home
    SP3 with all the original installed drivers over a network configured
    connection and a firewall configured). This system will upgrade
    XP Pro with XP Pro SP3 slipstreamed CD successfully.

    Experiment 1:

    I've restored my minimum system. I then restored the C:/Windows folder
    and the State of the pre-existing system backup system. A startup
    has managed (with a minor irritant). I had to activate Windows.
    Then, I tried upgrading the slipstreamed XP Pro processor. He stopped
    at the same place during the upgrade and gave the same error as before:

    Setup cannot set the required configuration information Windows XP.
    This indicates an internal Setup error.

    Experiment 2:

    I've restored my minimum system. I then restored the system state only
    the backup of the pre-existing system. After startup I was asked to
    activate Windows, but answer Yes to the question would be to disconnect me
    the system. I couldn't get connected to try the XP Pro upgrade.

    Experience 3:

    I've restored my minimum system. I then restored only the C:/Windows
    the backup of the pre-existing system folder. Once again, as in experiment 1,
    the upgrade failed at the same place with the same error message.

    ----------------------------------------------------------------

    Before the experiment 3, I hoped that 3 experience would succeed so I
    could conclude that I had a registry problem. I'm not sure now.
    I don't know what to try next. Take the minimum system and reinstalling
    my files of the user is not an option that my hard drive has over 200 GB of
    programs! If I restore all files and folders of my pre-existing
    I would still have backup to restore a system state the reliable (read the registry).
    ---------------------------------------------------------------------

    Sorry for the length! If anyone has any ideas I would appreciate your responses.

    Thank you

  • You cannot set declaratively developing the slider if you specify an ONLOAD.

    Hello

    In my application, I have two javascript functions in the Html header area... and by calling the onload in the Body Html attribute... This sceneriao he launched an exception as shown below...



    1 error has occurred
    You cannot set declaratively developing the slider if you specify an ONLOAD in this attribute. You can set update of the slider programmatically by using the following syntax:

    Thank you

    Hi David,

    On your page, go to your page attributes and you will see that it is to set the focus on the first field when the page loads. You need to remove what you can have only a single onload function call. If you need to set the focus, your onload function is adjustable to do this.

  • Cannot set new bookmarks; Some have disappeared; saved but rebuilt; lost a lot more. Help!

    Problem has grown gradually over a period of 2-3 days. First of all, some favorites have disappeared from the toolbar. At the same time, 'Bookmark this Page' has stopped working, and cleared from the list "recently set bookmark". When I followed the recommended procedure Firefox for backup and restore, I repeatedly had the message that Firefox could not process the restoration. Then 3/4ths my bookmark folders disappeared. This happened it try with different dates backup. Now, I find that a number of other people have similar problems. Like some of them, my problem may have begun during a restart because of a deadlock in another program. Mozilla's Support system seems far too complicated, time-consuming and circular, and talking to a person live doesn't seem to be an option. If this is not corrected within the next 24 hours I'm trying other browsers, after use Firefox almost exclusively for several years.

    I see that you have the extension of Maintenance of places. Using this fact no difference to your ability to add bookmarks, or stop losses?

    To test the integrity of your backup files of bookmark, I will suggest you try to restore one or two of them to a new profile.

    Since I'm a Windows user, I apologize in advance if this answer is not entirely applicable to your system.

    Bookmark backups in a convenient location

    Open the settings folder (AKA Firefox profile) current Firefox help

    • button "3-bar" menu > "?" button > troubleshooting information
    • (menu bar) Help > troubleshooting information
    • type or paste everything: in the address bar and press enter/return

    In the first table of the page, click on the button 'show in Finder '. This should start a new Finder window. Then, double-click the folder bookmarkbackups . Copy some of your recent backups on the desktop or another location.

    Create a new Firefox profile

    Leave Firefox runs. Start up in the Profile Manager using the method in this article: use the Profile Manager to create and delete profiles Firefox.

    Notes:

    • Do not delete anything here!
    • Any time you want to switch profiles, leave Firefox and return to this dialog box.

    Click on the button create a profile, give it a name like Test0426 and skip the option to change the location of the folder. Select the new profile from the dialog box, and then start Firefox.

    Test bookmark backups

    Firefox in the new profile should look like a new installation of the plant. You can use the steps in this article to test one or more of the files you copied to your desktop (or another location): restoration of the bookmarks from a backup or move them to another computer (use the option of choosing a file instead of one of the dated options).

    Firefox in the new profile read and restore the backup?

    Return to your Normal profile

    Exit Firefox and look at this article: use the Profile Manager to create and delete profiles Firefox.

    When you return to the Profile Manager, you might be tempted to use the button Delete a profile on Test0426. It's a little too easy to accidentally delete your 'real' profile, so I recommend you to resist the temptation. If you don't want to clean up later, I suggest to make a backup of all your profiles first in case something go wrong.

  • Tecra A4: Cannot set the resolution of 1280 x 800

    Hi all.

    I have a Tecra A4, and for the last 2 days I am trying set up the screen at native resolution of 1280 x 800, without sucssess.

    I try a lot of things, like updating drivers, use the restoration of the system, the value 'stretch' in the BIOS, etc, but this resolution do not appear on the display settings (I use XP SP2). I've only 800 x 600 and 1024 x 768.

    In any of these resolutions, a wide black border appear to the right of the screen. A small border appears on the bottom, too.

    Please, how can I solve this problem? I don't want to use the Toshiba restore, some programs I use are very difficult to find and install.

    Thank you.

    You cannot set this resolution if this resolution of 1280 x 800 is not part of the display driver.
    The graphics card driver contains all available resolutions and if one is missing, I mean not rated, it s not able to select

    I have a satellite a30. I just upgraded to broadband and cannot configure the WiFi wizzard. the modem is working perfectly thanks to threads, but cannot set up wireless despite my efforts! Please can someone help?
    see you soon
    Claire

    Hello

    What's the problem?
    You are not able to see the thread or what?

    Are you sure of the laptop and built-in wireless network card?

    Remember that the WiFi card is optional on the Satellite A30 and not all models includes the Wlan miniPCI card
    Thanks for posting more details!

    PS; If the laptop supports a WLan card internal, you should check only that steps;

    -Check if the WLan adapter is enabled on the laptop. Activate the switch on the side of the laptop and the FN + F8 key combination!
    -Check if the windows own WLan configuration is marked
    -Be sure that you use the right WLan encryption and whether encryption is supported by WLan modem (router) and wireless network card
    -Check if the standard 802.11 WiFi, B or G is accompanied by WLan modem (router) and wireless network card
    -Make sure that the router MAC filtering option has been disabled!

    As you can see all of these options are important to connect to the wireless LAN.

  • Cannot insert field or paste into the existing local Variable (Boolean container)

    Cannot insert field or paste into the existing local Variable (Boolean container)...  TestStand 4.1.

    It is very strange, especially since I've done it before.

    'Paste' and "insert field" selections are grayed out and disabled in the context menu.  I tried everything I could imagine and tried various combinations of positions.  I'm sure it's something simple, bu redicoulously, I can't find the redicule to solve this annoying problem issue.

    The local variable is a container of Boolean.  It has 90 elements and I need to add one more.  I can not change / rename or do something with this Local.  Must be karma (for those who know me in the LabVIEW forum).  Usually, you do a right click, insert field and that's where...  Not this one...

    Anyone seen this before?  Closing and re-opening TestStand doesn't change anything.  There is a collection in LabVIEW that feeds the local section in TestStand.

    It is a container of data custm type.  To change flags are ok (edit is allowed).  Can't think of any other valuable information...

    It should be edited in the Data Types...  It was not automatic after reloading the prototype of LabVIEW.

    I knew it was something stupid that I didn't...  I became close... but had not sought far enough.

    The valid IP address would start by 192.168 if the IP address starts with 169 or something else is not a valid IP address.

    If the address of your router is 192.168.1.1 then the IP of the printer should be something like 192.168.X.X
