Please help me to understand what causes the above error.

Hello

I was able to get your application working under Flex 3.5 with a few modifications.  First of all, I had to add brakets curly around RemoveChild objectives, as well as the properties of AddChild relativeTo.  Finally, I removed the extra space in the cancelButton click method.

Hope this helps,

Chris

Here's the modified code:

  • TypeError: Error #1034: Type constraint has no

    Hi, I use a ready Panel accordion in Flash ( here )

    now, when I add a touch any on this frame I get this error when I click on the tabs of the accordion:

    TypeError: Error #1034: Type coercion failed: cannot convert flash.display::SimpleButton@48596ab9 to flash.display.MovieClip.


    and when I add a movieclip on the stage I get this error just after click on all of the accordion panels:


    TypeError: Error #1010: a term is undefined and has no properties.     at mobver2_fla::MainTimeline/onClick()


    Here are the main script for the accordion panel:

    import gs.*;
    import gs.easing.*;
    
    panel1.props = {ly:53, ry:650, ind:1};
    panel2.props = {ly:115, ry:700, ind:2};
    panel3.props = {ly:169, ry:750, ind:3};
    
    panel1.addEventListener(MouseEvent.CLICK, onClick);
    panel2.addEventListener(MouseEvent.CLICK, onClick);
    panel3.addEventListener(MouseEvent.CLICK, onClick);
    
    function onClick(e:MouseEvent):void
    {
        var clicked:MovieClip = MovieClip(e.target);
        for(var i:int=0; i<numChildren; i++)
        {
            var mc:MovieClip = MovieClip(getChildAt(i));
            if(mc.props.ind <= clicked.props.ind)
                TweenLite.to(mc, 1, {y:mc.props.ly, ease:Bounce.easeOut});
            else
                TweenLite.to(mc, 1, {y:mc.props.ry, ease:Bounce.easeOut});
        }
    }
    

    It seems to this script on all effect the movieclip or buttons in the frame, but I can't understand how I need to separate from the other buttons and movieclips from that. I really need to add some button and movie clip on these panels and the frame

    For the first error, the onCLick function is not letting a child on stage through without that he's trying to turn it into a MovieClip via the line:

    var mc:MovieClip = MovieClip (getChildAt (i));

    What you need to do is to check the type of each object before you try to turn it into something that can not.

    • function onClick(e:MouseEvent):void
    • {
    • var click: MovieClip = MovieClip (e.target);
    • for (var i: int = 0; i
    • {
    • If (getChildAt (i) is the MovieClip) {}
    • var mc:MovieClip = MovieClip (getChildAt (i));
    • If (mc.props.ind<=>
    • TweenLite.to (mc, 1, {y: mc.props.ly, ease:Bounce.easeOut});})
    • on the other
    • TweenLite.to (mc, 1, {y: mc.props.ry, ease:Bounce.easeOut});})
    • }
    • }
    • }

    For the second errorit could be the case when there are other movieclips that are children who do not attend the accordion and should not be run thru that treatment is because they have not the properties they need

  • TypeError: Error #1034: has no Type constraint: IFocusManager + button

    I'm writing an application that only uses the keyboard to navigate through the components on a page.

    When the user clicks the button the arrow, emphasis is placed on the component that has focus.

    For example, I have a container that has several images page layout, the user can access other images

    This container by using the arrow keys.

    First of all, I tried to use images as the component to store the image, but I discovered that I could not set the focus on a

    component images. Then I used buttons and set the property to the icon of the source of the image, and it worked fine.

    But then I did a botton in another mxml component, I named ButtonImageGadget so that I could put the icon property the

    the main application file. When I run and navigate to the switch that is a button is buttonImagel file, I get an error.

    «TypeError: Error #1034: Type constraint failed: cannot convert components::buttonImage@121ca15c1 to mx.managers.IFocusManagerComponent.»

  • Cluster HA agent has an error

    ESX 3.5 - 2 cluster nodes managed by VCenter 2.5

    Works fine until last week when I saw the error displayed on the second node "HA agent on xxx in yyy in zzz cluster has an error.

    I clicked on "Reconfigure for VMware HA" and it worked for about 30 seconds then wrong again.

    The events detailed for this host in VCenter say enough resources when activating then changes to insufficient resources to meet the HA failover the cluster level.

    We have not added all new machines on each host, or if the configuration has changed. Allocation of resources is 0-10% CPU and 20-30% on the single host RAM and RAM of 30-40% on the second host.

    I checked the file vmware_hostname.log on the host problem and is the only thing that seems wrong

    Error FT Mon 5 Nov 14:22:14 2012

    MESSAGE: Rejected the Message. msgid 98 of (1 / 3:24716.0)

    Then it continues with "Node works" and both hosts receive heartbeats from each other.

    We have tried to disable HA and reactivation, but that has not worked.

    In the DNS and routing, the two hosts associated field, preferred/alternate DNS, research areas, default gateways for the service console and VMKernel (all in lower case too).

    Running out of things to try/check! Any direction would be appreciated.

    First thing we do is to check the following:

    (1) is activated the admission control?

    If the answer is Yes:

    (2) is there a reserve set to any of the virtual machines?

    I guess that the answer to both is still. Remove the reservation or change the type of admission control you are using. To learn more about the admission control, you can find the details here: http://www.yellow-bricks.com/vmware-high-availability-deepdiv/#HA-admission

  • All few minutes my computer has an error

    All few minutes my computer has an error: plugin - container.exe has encountered a problem and needs to close. -What it means and how to fix it?

    Maybe as Support engineer who is hired by Microsoft does not know this plugin - container.exe is part of Firefox and has nothing to do with Windows XP.

    You must be sure that you are on the latest version of Firefox (currently 11.0)

    You need to clear your cache/temporary Internet files.

    You must scan your system for malware.

    It could be that you have a distressed Firefox extension, so you should check for updates too.

    If the problem seems to occur regularly on any particular WWW site, this site could be afflicted in some way.

    You should then see if the problem persists and if so, display the full message, you see.

    No matter what you use for malware protection, follow these steps:

    Download, install, update and do a full scan with these free malware detection programs at:

    Malwarebytes (MMFA): http://malwarebytes.org/
    SUPERAntiSpyware: (SAS): http://www.superantispyware.com/

    These comprehensive analyses can take some time, but you really need to run.  SAS will probably be just a bunch of Internet tracking cookies, but you can remove them.  Once you have done at least a full analysis, you can do quick scans in the future to save time and save the analyses complete for when you have more time or are really suspicious of an infection of the system.

    They can be uninstalled later if you wish.

    In 1985, there were 11 known computer viruses.  Today, there are over 70,000 and new threats are detected every day.  Always update your virus definitions before running a scan.
