Error in datagrid

Hi All,
I got an error in the dataProvider for my comboBox that is
inside of the
datagrid.
Data binding will not be able to detect assignments to
"acServiceCategory".
Any ideas why?
Tks
JFB
is acServiceCategory set to [Bindable] ?
e.g.
[Bindable]
private var acServiceCategory:ArrayCollection;

Flex 4 - Error with DataGrid in Module
Hey, I'm using Flex 4 final and am now getting the following error when loading a Module with a DataGrid inside:
TypeError: Error #1009: Cannot access a property or method of a null object reference
at mx.styles::StyleProtoChain$/initProtoChainForUIComponentStyleName()[E:\dev\4.0.0\framewor ks\projects\framework\src\mx\styles\StyleProtoChain.as:356]
It is created via MXML:
<mx:Module layout="absolute" xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:mx="library://ns.adobe.com/flex/mx">
<mx:DataGrid>
... config etc.
</mx:DataGrid>
... other code
</mx:Module>
If I remove the DataGrid the Module works fine. The code used to work in the various betas.
If I put a DataGrid in the main application that also renders fine, so it's only inside Modules.
Thanks in advance for any help or ideas!Hi Darrell,
I have the exact same error, and yes I am using module.factory.create() but I get an error when I try to add the module to my stage. Here it is the code in my modReady function.
var _sd:Object = new Object();
_sd = util.app.SDModule.factory.create() as SequenceDetail;
_sd.sequenceId = event.currentTarget.selectedItem.sequenceId;
_sd.environment = event.currentTarget.selectedItem.environment;
_sd.seqname = event.currentTarget.selectedItem.sequenceName;
util.app.page.addChildAt(_sd as SequenceDetail, util.app.page.numChildren);
util.app.nav_buttons.selectedIndex = -1;
util.app.page.selectedIndex = util.app.page.numChildren-1;
I get an error on util.app.page.addChildAt(........).
error is
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Comma prompt error in datagrid
I had created a timetable in the datagrid. The datagrid is
able to display individual staff's tiimetable. However, I was
prompt an error when I click on this particular staff to view the
class schedule. I found out that the error is caused by a comma in
the rows in the database while the other individual staff's
timetable works fine without any comma found in the the rows.

Have you done anything on the web service side to ensure that
the object
coming back is an ArrayCollection? I think you need to use
something like
JSON to make that happen, but I'm not a webservice person.
Are you sure that you ought to be using a HTTPService here?
Maybe what you
need is HTTPRequest instead. -
Getting error on DataGrid click
Flex Builder 3 build 3.0.2.214193
I seem to be getting this error when clicking on the scrollbar arrows when it reaches its top or bottom:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at InfusionProspectsList/displayDetails()[D:\Documents\dev\flex\InfusionProspectsList\src\In fusionProspectsList.mxml:16]
at InfusionProspectsList/__grdProspectData_click()[D:\Documents\dev\flex\InfusionProspectsLi st\src\InfusionProspectsList.mxml:83]
Also, I am getting the next error when I click on a row, but when I click continue and go back to the row it is fine:
ReferenceError: Error #1069: Property data not found on mx.core.SpriteAsset and there is no default value.
at InfusionProspectsList/displayDetails()[D:\Documents\dev\flex\InfusionProspectsList\src\In fusionProspectsList.mxml:16]
at InfusionProspectsList/__grdProspectData_click()[D:\Documents\dev\flex\InfusionProspectsLi st\src\InfusionProspectsList.mxml:83]
I have no code attached to the scrollbar, and have a function attached to the data grid itself to populate some detail fields.
Any ideas?
Thanks.Only the debugger player shows uncaught errors. Release players stop
running code until the next event or frame. The error is showing you a line
number in your code. See that code is on that line. -
VerifyError: Error #1025: An invalid register 2 was accessed
hi,
i have an this xml file to read
<test xmlns:"

i put is in an arrayCollection ,data, and when try to execute
this code i have an error

dataProvider="{data}" xmlns="

</mx:columns>
</mx:DataGrid>This turned out to be either
var myFunc:Function=someFunctionFromOurCode;
myFunc.apply(null,args);
//OR
myFunc.call(null);
changing the nulls (thisObj params) to something more appropriate killed the bug.
The reason I was setting the thisObj to null is because none of the functions getting called required a "this" scope -
I'm trying to use HTTPService to receive xml data from a
website, using e4x, then put it in a datagrid (and do other things
with it later). I can get it to populate the datagrid using object,

an XMLListCollection, but can't seem to get it working.

Thanks in advance.Using that I get these console warnings:
warning: unable to bind to property 'projects' on class 'XML'
(class is not an IEventDispatcher)
warning: unable to bind to property 'project' on class

Also, I can't figure out why lastResult is returning null if
I work with it in the same function list_request was called from.
public function GotoStartPage():void{
list_request.send();
// If the query contained a value for project_request...
if(Application.application.parameters.project_request!=null){
// Check to see if the query matched one of the listed
projects
project_request=Application.application.parameters.project_request;
currentState="Main Project Page";
}else{
trace(list_request.lastResult); // <-
this gives null
project_request="";
currentState="Project Selection Screen";
Is the trace statement getting called before
list_request.send() is finished getting the data? -
Error while inserting data in datagrid
Hi,
I am trying to insert data into a datagrid getting results
from a cfc using remoteobject. If I use everything inline then it
works fine.
I have a button when clicked give me the results. if I have
something like this:
<mx:Button label="get Query Remote Object"
click="myTest.getSystem()"/>
then it works fine.
but if I use a namespace like
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
xmlns:serv="services.*">
<serv:services id="services" />
and try to use
<mx:Button label="get Query Remote Object"
click="services.myTest.getSystem()"/>
then i get an error saying
Access of undefined property myTest in package services.
I have the remoteobject call within services.mxml which is
inside services folder. What do I need to change? It used to work
fine in 1.5.
ThanksAre you using the Cairngorm framework or why are you using a
sevices.mxml?? -

You are trying compare String and int..! which is not possible try to case the txtIn.text to int using parseInt(txtIn.text).
ORIGINAL:
if(txtIn.text != ADD_TASK).---->error : Comparison between a value with static type String and a possibly unrelated type int
tasks.addItemAt(new Task(txtIn.text, 0, ""), e.rowIndex);----> error:Implicit coercion of a value of type String to an unrelated type int.
EDITED:

Error #1009 at mx.controls::DataGrid/mx.controls:DataGrid::mouseUpHandler()
Hello.
At first sorry for my english.
I have encountered problem with DataGrid control.
There is DataGrid control, which have custom ItemRenderer
(MulticolorDataGridItemRenderer).
This DataGrid control has several properties:
1) click on a row changes it background color
2) click on "Filter ON" button, filter DataGrid by "status"
field
"TypeError: Error #1009: Cannot access a property or method
of a null object reference.
at
mx.controls::DataGrid/mx.controls:DataGrid::mouseUpHandler()"
This error occure when filter is ON, by click on a row. It
occures occasionally. I note that it
occur when DataGrid's vertical scrollbar is not in top
position.
If I remove recovering of scroll position, this bug
disappear.

And one another question: why did disappear standard DataGrid
control selection mechanism, when I used custom
DataGridItemRenderer? Try to use the sample code above withou
fnSelectRow function.
TIAHi, I will try to explain what i have undestood about this issue.
I have an application that loads at runtime some modules, and in my project configuration (Flex Modules), i specified some modules to compile optimizing to main application. Besides that, my project uses RSL to the framework linkage, and i perceived that the compiler output reports some warning messages just like "The CSS type selector 'DataGrid' was not processed, because the type was not used in the application." or others similars "The CSS type selector 'TextArea' was not processed, because the type was not used in the application.".
When i run the application, and click the first time in some grid column, the error "Type Coercion failed: cannot convert ......@abcda2 to ........." happens.
It happens because, these controls or components has not been linked in the main application compilation, and so, when you use the first module that uses one of these components, only the module loads an instance of these components and maintain on its part of memory.
Dispite of being loaded in the main application, each module and main application has its SystemManager instance to register and load components, and because of it, when the application try to cast instances of the same component, but at differents SystemManager's singleton implementations, the above error occurs.
So my solution was to add some reference of the controls or components that appears at the warning messages that was not compiled, to force the main application compilation to add these components at its SystemManager singletons first than any module.
Only add the name of the component and import its package. Do not have to add to the stage. See below.

After app initialized i call ResourceManager.getInstance().localeChain = [language]; (language = "fr_FR"). I tried "fr" "en_US" "pt_BR".. Same problem.
This problem is only in AIR project.
Anyone already solved this problem? -
Advanced Datagrid error in Flex 2

I copied the source of Advanced Datagrid and the related

Sorry, we do not officially support this.
Is there any particular reason why you cannot using the
