Chart causing error 1009 when enabling compatibility mode in Flash Builder 4

Hello.
I'm trying to use the chart components in Flash Builder 4. I'm using Flex SDK 4, but had to turn on the "Flex 3 compatibility mode" for some off-topic reasons.
I simply created a new application and copied the code from the DateTimeAxis class example: http://www.codigoactionscript.org/langref/as3/mx/charts/DateTimeAxis.html#includeExamplesS ummary
When running the example, the following error is reported (sorry, it is in italian: it's simply the "null object" error):
TypeError: Error #1009: Impossibile accedere a una proprietà o a un metodo di un riferimento oggetto null.

at mx.managers::LayoutManager/doPhasedInstantiationCallback()[E:\dev\4.0.0\frameworks\projec ts\framework\src\mx\managers\LayoutManager.as:1072]
Is there a solution to this bug? We really need to use charts AND keep the Flex 3 compatibility mode.

I use SDK 4.1 but I also get the error: (Flashbuilder 4.0.1 in Flex 3 compatibility mode)
TypeError: Error #1009: Cannot access a property or method of a null object reference.

So I guess it is not solved....

Error #1009 when creating apps in App Builder

Customers using DPS App Builder to create applications with .mobileprovision files created in the iTunes Developer Portal after 7/17/2014 are experiencing error #1009 when attempting to create the application. This only impacts customers using .mobileprovision files created after 7/17/2014. Older .mobileprovision files will work correctly.
We are investigating the changes necessary to update App Builder to support recent changes to the .mobileprovision files generated by the iTunes Developer Portal. An update will be posted to http://status.adobedps.com/ by Monday, July 21st, at 8am PDT.

Hi，
Based on my research, there are many factors can cause this issue. For more details, we can refer to the following possible causes:
Some configuration did not configure well. Open the Reporting Services Configuration Manager to check all the configuration, see
http://msdn.microsoft.com/en-us/library/aa337424(v=sql.110).aspx on Reporting Services Tools.
In the reporting services configuration manager tool, rebuild the virtual directory of report manager/report server.
If the report server enables SSL, recreate a certificate and then rebind it to report server.
It may resulted in config file of the report server / service.
changing the AuthyenticatonTypes to RSWindowsNTLM in the report server config file.
Besides, the issue can also be caused by the web.config for the SharePoint site was not correctly modified by the Reporting Services Add-in for SharePoint. For more details, please see the following posts:
http://social.msdn.microsoft.com/Forums/sqlserver/en-US/a8a66827-0995-4f87-bcae-f7750fa5d3fa/error-client-rendering-the-remote-server-returned-an-error-403-forbidden?forum=sqlreportingservices

Using papervision in flash builder and getting TypeError: Error #1009: when using object.pitch(5)

When i use papervision in flash builder and i am doing a test, when i render a sphere using papervision with the following code it renders me the sphere.
When i add a line sphere.pitch(2); ||
sphere.yaw(2);
sphere.roll(2);
i get the following error,
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at PvTest/onRenderTick()[D:\Android 3D\PvTest\src\PvTest.as:39]
Can anyone help me figure out the error
For additional Info, these are the imports i am doing:
import org.papervision3d.objects.primitives.Sphere;
import org.papervision3d.view.BasicView;

I followed the steps and read some of your comments on the same top topic in another thread. When I put it on the first frame it was okay but the next button on that page had the same problem. So what I am guessing is that I have to either create a document class or put the actions where the buttons are. Am I understanding that correctly? In the other thread in which you helped someone else; there was so comments about document class. I found a tutorial on it and the way I understand it is that it you can put you actions in an external document. But you have to include in the event listener the frame in which you want that action to happen.
Thaks for your help. And patience.

Cannot read a file using Acrobat SDK in Adobe Reader 11 when Enable Protected Mode is checked

I wrote a plugin using Acrobat SDK which reads a temporary file created by another program in TEMP folder. In Adobe 10, plugin can read the temporary file and everything works. In Adobe Reader 11, plugin fails to read the temporary file when Enable Protected Mode option is checked. When I uncheck this option, everything works fine. Our customers are concerned about disabling this option. Please let me know if there is a workaround for this issue without unchecking the option. Thank you.

If you have FCPX (10) you can upgrade for free at the MacApp Store.
Did you click "proxy media" when importing? That will help playback.

After reading this discussion thread, I've seemed to have solved the problem for myself. I'm using the Trend Micro PC-Cillin Firewall. I disabled it and the airtunes worked. So, I went into the firewall settings. There's the ability to edit the profile and add to an exceptions list. You select the executable program, select incoming or outgoing, I accepted the other default settings and it worked.

Get client browser version in C# (When IE Compatibility mode enabled)

We need to know client's browser version from C# code (Server side). We use Request.Browser or HTTP_USER_AGENT to get the details.
However, In IE when compatibility mode is enabled it always returns IE 7 version irrespective of version of IE. ie, even in IE 11 when compatibility mode enabled it returns IE 7 but I want actual version which is IE 11. Is there any way I can get actual IE
version?

Addin is not loaded when in compatibility mode

Hi there!
I have a plugin that is loaded on my machine when I start Word 2010 as I want it to do. But if I load documents from Word 97 or 2003 and the application starts in compatibility mode my plugin is not loaded.
Is threre anywhere a switch in my project properties or in word to make the plugin work in compatibility mode too?
Regards Sebastian

Hello Sebastian,
There is no special settings for that. Did you have a chance to check out the COM Add-ins list in Word?
Is your add-in listed in the Disabled Items list?
Microsoft Office applications can disable add-ins that behave unexpectedly. If an application does not load your add-in, the application might have hard disabled or soft disabled your add-in.
Hard disabling can occur when an add-in causes the application to close unexpectedly. It might also occur on your development computer if you stop the debugger while the
Startup event handler in your add-in is executing.
Soft disabling can occur when an add-in produces an error that does not cause the application to unexpectedly close. For example, an application might soft disable an add-in if it throws an unhandled exception while the
Startup event handler is executing.
When you re-enable a soft-disabled add-in, the application immediately attempts to load the add-in. If the problem that initially caused the application to soft disable the add-in has not been fixed, the application will soft disable the add-in again.
You can read more about that in the
How to: Re-enable an Add-in That Has Been Disabled article in MSDN.

Module Chart component Error #1009: Cannot access a property or method of a null object reference

Is there a known bug when displaying a chart component that is defined in a module. When attempting to display a chart component defined in a module it crashes indicating Error #1009: Cannot access a property or method of a null object reference.
It crashes at the following location in ChartBase.as. Somehow when loading the chart the styleManager.getStyleDeclaration("mx.charts.chartClasses.ChartBase"); returns null so when using the setStyle methods the exception occurs.
private function initStyles():Boolean
        HaloDefaults.init(styleManager);
var chartBaseStyle:CSSStyleDeclaration = styleManager.getStyleDeclaration("mx.charts.chartClasses.ChartBase");
chartBaseStyle.setStyle("chartSeriesStyles", HaloDefaults.chartBaseChartSeriesStyles);
chartBaseStyle.setStyle("fill", new SolidColor(0xFFFFFF, 0));
chartBaseStyle.setStyle("calloutStroke", new SolidColorStroke(0x888888,2));
        return true;
Added note: There is a chart component in the application that works fine. The only way I can get the chart in the module to display is to add the following workaround preinitializer but it severly impacts the loading of the module. Is there a way around this.
protected function preinitializeHandler(event:FlexEvent):void
   var styleObjects:Array = FlexGlobals.topLevelApplication.styleManager.selectors;
   for each(var styleObj:String in styleObjects) {
    var style:CSSStyleDeclaration = FlexGlobals.topLevelApplication.styleManager.getStyleDeclaration(styleObj);
    styleManager.setStyleDeclaration(styleObj, style, true);

ESSO Error with IE 9 Compatibility Mode

Can anyone help? We are implementing eSSO with OIM 11.1.2.. When testing the system, we receive an error that Compatibility Mode should be turned off. We can turn off Compatibility mode and the user can access the site fine while they are logged in. But when we try to access the site from a locked screen, we get the following error. "The current compatibility setting is not supported. Disable Compatibility View before running this web page." If you click OK, the page loads fine.
We have applied GPO's to force the Compatibility Mode Off.

Hi JimmyWeise,
Can you try to download Microsoft SilverLight Browser Plugin and install into IE9. Then try to validate the same.

I'm not sure what is null, as I don't have the source code
for the HistoryManager. It seems to be generating an error while
attempting to initialize a component that is part of the module
that it is currently loading. The strange part about this is that I
can load the module a once and then it will error, as show below:

There are also times that it will error on loading another
module just once.
Now, I am loading all my modules through the same
ModuleLoader without unloading them. I assume that this is correct
way to do this.
If I comment out the offending component, everything works
fine. The components worked fine before when I had them in
applications.
Not sure where to go from here... any ideas would be great.
Thanks in advance.

I am getting the same error loading modules. For me I found
that changing the layout properties of the container that I am
loading the module in made the problem appear and go away. I'm
loading a module as an itemrenderer in a TileList. If I set the
columnWidth and rowHeight properties of the list then I have
problems. If I don't set them both, then I get the
"ModuleManager.as:671" null pointer problem. I'm guessing that by
setting the size ahead of time for the itemRenderer flex doesn't
need to query the module until later which gives it time to load.
Seems like a race condition to me. This is yet another bug in flex.
My application populates a number of VBox ( the number of
boxes are based on the xml data). Each VBox loads the module with
different data set. The module only contain advancedatagrid. The
VBox's size are preset with percentwidth and percentheight prior
calling a module loader. I also tried to specified the size in
pixels. But, no luck.
Once a while, I got the below messages at the console window
running in debug mode. Is the unload swf message normal? I have no
intention to unload the module in my code. If the module shouldn't
be unload, then obviously there is a problem.

Error 1009 when accessing webservice elements

I'm learning flex and Flash Builder 4.6 and doing a small example project.
I've created a mobile app test using a web service. I got the web service to work, creating xml dataset. I can get the flex code to access the web service and read the file. That works so far. The code reads the whole xml file from the web service and presents it. What I don't quite see is how to read only the elements. When I specify the .LastResult.element.element I get Error #1009: Cannot access a property or method of a null object reference. during runtime.
I can post the webservice xml result if that helps. Thanks for any insights.
Here's the code

I'd have to see the xml to say what, but 1009 is what it says - a null reference has no properties, it is null.
Try tracing out SampleWebServiceCS.GetMember and you'll quickly see where along your .element.element path you have an error.
(BTW, I've not used s:Operation before, but is your syntax correct?)
