FLEX ReferenceError in SystemManager at startup?

Nov 18, 2012 11:53 AM

Tags: #flex ##1069 #systemmanager #referenceerror

So I am having a strange error this morning.  My Adobe FLEX app was compiling just fine on Friday, but now today whenever I attempt to debug or run it, I am getting this runtime error right at the very beginning:

 

 

    ReferenceError: Error #1069: Property http://www.adobe.com/2006/flex/mx/internal::topMostIndex not found on _Main_mx_managers_SystemManager and there is no default value.

    at mx.managers::SystemChildrenList/addChild()[E:\dev\4.y\frameworks\proj ects\framework\src\mx\managers\SystemChildrenList.as:128]

    at mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/internal::initialize()[E:\dev\4.y\frameworks\projects\framework\src\mx\managers\SystemMana ger.as:2014]

    at mx.managers::SystemManager/initHandler()[E:\dev\4.y\frameworks\projec ts\framework\src\mx\managers\SystemManager.as:2582]

 

That is the only trace that comes out with it, so it looks to me like it's something built into FLEX and not my code that may be hiccuping.  I've had strange errors before that a Clean was able to solve, but I have attempted to clean and rebuild my debug version but I am still getting this error.  I restarted Flash Builder, and even restarted my computer - no dice.  Even when I export a release build, my firefox flash debugger catches the same error.  Existing copies on my app on the web seem unaffected.  I reinstalled my flash content debugger for netscape (I use firefox as my main browser) and no go.  I don't even think an update was automatically installed for flash as I have it notify me rather than just do it (even double checked those settings).

 

Short of just reinstalling flash or flash builder I am not sure what to do.  Any suggestions?  I am at a loss for what this error means or how to fix it.  I am not even ruling out the possibility that I messed something up in my code, but I have no idea where to look as the stack trace only has 3 lines - and none of which is my code.

 

Thanks in advance for your help!

 

EDIT:  I want to add, that when I dismiss the error, my app continues to run seemingly normally.

    Something is bad in the output SWF.  Try a simple new project and see if you have the same problem.  If you do, it sounds like the swcs might be damaged.

    I'm experiencing the same issue since Friday (11/16). Any luck resolving it?

     

    Also - the error only seems to occur in Firefox (running 16.0.2). Chrome, Safari, and IE run fine.

    Disabling and then re-enabling Flashbug fixed it for me. Perhaps coincidence, but it fixed it on both my machines…

    Good call Benj1master, uninstalling FlashFireBug 4.57 did the trick for me. Reinstalling it presented the error so I've removed it completely.

    Same here.  Disabling FlashFireBug 4.57 fixed the error, but re-enablign it brought it back.  It'll stay disabled for now.

    Could you kindly try FlashFirebug 4.58 which is still on the approval queue? You can download it here:

     

    https://addons.mozilla.org/_files/161670/flashfirebug-4.58-fx.xpi

     

    Let me know if it solves the problem. I would guess it should get approved by Mozilla today or tomorrow.

    Seems since it's thanksgiving, approval of this will be delayed till Monday the 26th. Of course everyone is free to download the version before it's approved. But we're eagerly waiting until it's pushed to all FlashFirebug users
