Update XML does not appear between States

Hi gurus,

I'm fairly new to AS3/Flex and would like your help with a problem I encounter. I put in a Flex 2 project that uses two custom components in different States (i.e. 1 State uses A. State 2 uses component B). In these two, they are referencing the XML object that is specified in a separate file (i.e. Global.as) which is included in the main application file.

Here's my problem. If I switch between the two States, make changes to the XML object, these changes do not appear in the States unless I force a new databind() by assigning the XML object updated the dataprovider. I could just do this whenever the user switches the State, however, I don't think it's an effective way to solve the problem.

I was wondering if you guys could help me find a better way to solve this problem. Can fix us an event that triggers the reset of the databind XML ONLY when the XML object is changed?

Thank you.
-Ask

no particular reason, you don't have you wrapped list XML in XMLListCollection? That's what flex for you when you assign it a simple XML or XMLList element.

So in your Global.as right after:

public var carsXML:XML = new XML)





);

make one

public var carsXMLView:XMLListCollection = new XMLListCollection (carsXML.car);

and now you should use carsXMLView everywhere wherever you used to carsXML, as in DataGrid


dataProvider = "{Application.application.carsXMLView}" > "

and, while adding a new car to the list:

var newObj:XML = ;
Application.application.carsXMLView.addItem (newObj); / / .appendChild (newObj);

I hope this helps!

Please inquire the dataProvider of the DataGrid class.

Also note that the Application.application. * isn't a recommended method to pass data to the various components! Use what you already have or sets properties and set the data source.

  • NET 3.5 SP2 update KB985254 does not appear to install correctly.

    I use the automatic update of Winows on my XP Pro SP3 and when I was asked to install the updated Net 3.5 SP2, I did it and it appeared to install correctly.  However, Winows Update icon appeared again and again.  Then I noticed that when I stopped my FCP, there was an update waiting to be installed.  I logged off the coast, the update appeared to install but when I started, there was the ison of update again.

    On my laptop, installed upgrading, a reboot is required and installation is complete.

    Why my office co does not work?

    This is the same update offered over and over again.   I started the installer of Winows, removed the update in Add or remove programs and reinstalled, but the offer does not go far.

    However, I subsequently installed four optional updates, including Microsoft .NET 4.0 Framework Client Profile for Windows XP x 86 (KB982670) and the problem disappeared.  All just lucky, I guess.

  • All my addons have been deleted and lost. Even backup has been removed in the latest update of FF. Now addons will not appear and add on bar does not appear. How to fix?

    All the Addons are missing after a recent update of FF. Backup also failed. How the hell that happened? made me? Went back to recharge add on extensions that I needed to use. However, add it to the toolbar does not appear. Tried restoring add on extension of tool bar. Now I add it on the toolbar in the verified Tools menu that was not there before. However, add it to the toolbar doesn't show always upward. Custom selection is worthless because it does not show that the extension add ons. I can check the extensions downloaded in add it menu and they are activated. However, they are not work or appear as it should!

    It is a bigger problem than the simple click here or there.

    I would say definitely go for the clean reinstall of Firefox. Your problem is obviously much more complex then just a misconfigured setting or something. When you updated Firefox, something may be wrong. The instructions are in the post 5.

  • Since the update, the sender's name does not appear on the email list.

    Sender's name does not appear in the preview screen, so I can't tell if it's legitimate or scam email. If I move to junk e-mail, it appears in the preview screen.

    I see the problem now. I can add the column and see the name of the senders. I had installed the Conversations Thunder module, which has a column between. This column is empty. I reinstalled the add-on. It works fine now.

    Thanks for your help.

  • ForecastFox does not appear on a clean install of FF5 with active addon-bar and bar state-4-Eva installed.

    Newly formatted PC, Windows Vista. I did an installation of FF5, pulled down as the default download on the Mozilla site. Installed forecast Fox, did not show. Turned on the toolbar of the add-on, it now shows icons FireBug and anti-ad, but no ForecastFox. I installed the toolbar state-4-Eva, changed icons alignment right, but still no ForecastFox

    What stupid way of doing things in this extension! I've been using Firefox since 2002, have used or tried hundreds of different extensions, and it took me almost 10 minutes to understand how it works.
    No help here - http://www.getforecastfox.com/ - and the image is for a Mac, which is like what, 5% of the Firefox user "market."
    And their 'support' - Questions? Need help? - http://groups.google.com/group/forecastfox-users/ - shown on the download page, has very little 'answers', especially a bunch of questions from lost users.

    ForecastFox display is on the Menu bar, which is hidden by default in Firefox 4.0 and later versions on free software most, with the exception of WinXP - but it must appear when the customization mode is open, they are the tabs on top is selected or not. (I have no idea why it does not appear in your screenshot). You can also see if you press the Alt key, you must open view > toolbars and click on the menu bar to have it open all the time.

    More there is no instructions on how to configure and use this extension and is not easily detectable - they should use a 'premiere' page on the Options page of forecastfox with some kind of instructions and screenshots for all operating systems.

    http://www.getforecastfox.com/customize/16/ - to change the Options, such as adding a 'place', change 'units', etc. And the 'button' to 'customize' or move the screen only appears when this page is loaded in Firefox, even in a tab that is not displayed! (And that brings up a security problem with Firefox, because it is not a "secure" page, but it's something I'll bring in support of the Addon for one or one at Bugzilla)

    "Screen" can be moved to a different toolbar, but you need the mode customize open and 'slide' + with the circle around it (which only seems to be present during the loading of this page - http://www.getforecastfox.com/customize/16/ - in Firefox), to be able to move the screen to a different location. In addition, a lack of "convention" with personalization, use cursor changes that are not the same as with the other tens of thousands of Firefox Add - ons that are available for Firefox. "A helping hand with the extended index" is the usual cursor used to display the 'sweet spot' to 'slide' mode customize, but this extension uses the cursor to "move" instead - the ToolTip for that says "move".
    "Drag and drop to move Forecastfox.
    ' Close the page options to hide this icon.

    See CSS2 Cursor property - http://www.gtalbot.org/DHTMLSection/Cursors.html

    I hope that answers all your questions with the Forecastfox add-on.

  • KB955759 does not appear when I check the updates manually, but it appears with the yellow shield after you have enabled the automatic updates.

    original title: Windows Update acts confused - kb955759 does not appear when I check the updates manually, but it appears with the yellow shield after you have enabled the automatic updates.

    I just reset my CMOS settings, writing zeros for my hard drive, repartitioned, reformatted and used the recovery cd Gateway system to get my computer to Windows 98se - factory settings, except at the beginning of the recovery of the system, when it says "press any key for advanced options," I pressed a key and then I unchecked all the default (3rd party) applications including Norton and left only 2 checked: "Updated USB Hub" and "Windows Shutdown Supplement," while nothing has been installed, leaving only win98.
     
    Then I used my disc XP Home (SP2) update.  I, immediately after the upgrade to Windows XP, installed "Office XP with Frontpage, Developer Edition", then Norton 2012 before never connect to the internet.
    Then, I connected to the internet and continuously update of Norton, before ever hitting the Windows Update page. The first thing I did then was to activate Windows, and then activate the office.
    Then I hit the update of Windows "button" that says "get all your updates in one place... upgraded"Microsoft Update".  I, then, just kept hitting the page update and restart, until I find the SP3.  Then, I took a break, until the next day.
     
    I have an ADSL broadband, with a Linksys EtherFast PCI card.
     
    Then I got SP3, which installed without any problems.
    So I just kept "microsoft continuous update" manually (and reboot), until there is no more updates - EXCEPT, I always uncheck Windows Malicious Software Removal Tool - which was the only screening at the final stop for the night.  I think that I ticked the box "don't ask me about this update".
     
    Then, in the morning, after you have enabled automatic updates, I noticed the yellow shield - Windows security icon (or whatever it's called), so I clicked on it and checked it was tellimg me was available [when I checked "Custom Install (advanced users)"].  What showed was 1 update - 955759 KB.
     
    After the problem, already at the reformat (months and months), see the yellow shield telling me there are updates available, which were already installed (before rebooting), I checked manually on the internet with IE 8, pressing alt, "T", "U".  There is no updated list.  Then I checked through my history of update (twice), and KB955759 had not been installed.
     
    My update setting is to let windows download ('important') updates, but let me choose when to install them.
     
     
     
    What is the right - Windows Update (NO update important reporting) Site, or the yellow shield (reports [a] kb955759 [update])?
     
    I can not yet confirm he is supposed to be an update for XP home kb955759, because I was unable to locate any detailed documentation on this 'thing' that protect the yellow safety seems to think is a significant update.

    Comment 1: To my rquest, a moderator merged your thread in the Sub-forum Win7 updates with your wire in the Sub-forum of updates of Windows XP 20 Feb-12, c. 07:50 UTC.

    Comment 2: If you will not contact the MS Support on this issue?

    ~~~~~~~~~~~~~~~~~~~~~~~~~~

    Just for the heck of it, I have disabled the automatic updates, cleared my browser cache, checked manually, updates from microsoft (windows) and found none (with the exception of software malware removal tool windows [which I have not installed]).  Then, I turned the automatic updates on, and without even being connected to the internet, the yellow shield popped up with the kb955759 "update"...

    Repost...

    1. If you open Internet Explore (only!) to http://windowsupdate.microsoft.com and run a CUSTOM scan, KB955759 appears in results?... If so, you manage to install it and/or security updates available?

    2 after no. 1 above [<>], is the 'yellow shield' icon appears in the Notification area (on the left of your clock)?  .. and if yes, by clicking on the 'yellow shield' icon tells you that KB955759 or any other updates is ready-to-be-installed?  .. .and if so, you manage to install it?

    3 after doing 1 # & #2 above [<>], is KB955759 or any other updates offered as a ready-to-install update when you go off your computer?  .. .and if so, you manage to install it?

    ... I guess that clearing the browser cache does not erase 'downloaded' updates.

    Nope. If you want to clear the queue of the update...

    OPTION A:

    1. stop the automatic updates service:

    Start > run > (type or copy/paste) services.msc > click OK
    Double-click automatic updates > click stop
    (Stopping the service will take a moment)

    2 remove the contents of the download folder:

    Start > run > (type or copy/paste) %windir%\SoftwareDistribution > click OK

    Open the download folder and delete its content
    Close the window.

    3. start the automatic updates service:

    Start > run > (type or copy/paste) services.msc > click OK
    Double-click automatic updates > click Start
    (Starting the service will take a moment)

    OPTION B:

    1. open Internet Explorer (only!) to http://support.microsoft.com/kb/910336 [don't know the titles, etc..]

    2. make disappear/close the Troubleshooter automatically pop up.
