Advanced Datagrid error in Flex 2

Hi,
I copied the source of Advanced Datagrid and the related
classes from Flex Moxie SDK into my personal project and changed
the package name etc. wherever required. Now I don't get any
compile time error. But I get runtime error as
TypeError: Error #1007: Instantiation attempted on a
non-constructor.

at mx.managers::SystemManager/::initializeTopLevelWindow()

Is there anybody from Adobe to help me??
Thanks in advance.

Hi John,
Sorry, we do not officially support this.
Is there any particular reason why you cannot using the
AdvancedDataGrid directly (or derive from it)?
Thanks,
Swaroop

Does compiling an advanced datagrid using flex ant task require additional config other than the license property?

Hi,
    I am trying to build my Flex app which uses the Advanced Data Grid in a couple of locations. Originally, when I built the app using the flex ant tasks, I noticed the Visualization Trial watermark show up on the screen. I then added the license tag with the serial number to my flex-config.xml and re-ran my ant build. The watermark goes away, but then when I look at the advanced datagrid, the datagrid shows up with the hierarchy, but the data does not display in the grid (only the group by nodes are visible, not the data for the leaf elements). This works fine when I build the app using my Flex Builder. Is there something I am missing or need to add to my flex ant task to make this work?
Any help or guidance is much appreciated.
The following is the ant task to build the module that uses the ADG:

Grouping is done as expected. We have additional functionalities like soring / seraching of the result set. Either one is working fine. Other functionality throws excpetion mentioned below.
When any of the advanced datagrid grid column header is clicked for sorting, it throws exception. I have pasted the exception below for reference.

AudioElement causes an error in Flex 4

Greetings,
A few days ago Ryan and Brian helped me to patch the problem wtih importing video into Flex by using the 'loadForCompatibility' flag.
This morning I ran into similar problem with audio: the SWF that uses simplest OSMF player plays fine in the Flash CS5 and in the standalone FlashPlayer. Once I import the SWF into Flex 4, even with the SWFLoader flag 'loadForCompatibility' set to 'true', I get this error:
Here is the code for the simplest audio player class (by the way, for some unclear reasons getter/setter didn't work, so for the test case I had to set the variable as 'public' ):
package
import flash.display.Sprite;
import org.osmf.media.MediaPlayer;
import org.osmf.media.URLResource;
import org.osmf.elements.AudioElement;
public class LightAudioElement extends Sprite
public var audioPlayer:MediaPlayer;
public function LightAudioElement(aSource:String)
var resource:URLResource = new URLResource(aSource);
var audioElement:AudioElement = new AudioElement(resource);
audioPlayer = new MediaPlayer();
audioPlayer.media = audioElement;
audioPlayer.autoRewind = true;
And here is the code for the SWF:
import LightAudioElement;
import flash.events.MouseEvent;
var snd:LightAudioElement = new LightAudioElement('assets/Test.mp3');
snd.audioPlayer.autoPlay = false;
//Standard Button component dragged on the stage for this quick test
sndBtn.addEventListener(MouseEvent.CLICK, clickHandler);
function clickHandler(event:MouseEvent):void
if(snd.audioPlayer.playing)
snd.audioPlayer.stop();
else
snd.audioPlayer.play();
Once again, it works fine in both Flash CS5 and standalone FlashPlayer, but produces an error in Flex 4. I'm on OS X 10.6.3, the Flex SDK 4.0
Thanks in advance for any suggestions,
FTQuest

Hi,
First, and foremost. As Brian Riggs - who is ultimate authority on the subject - has said:
I'd advise against replacing Flex's OSMF.swc with the latest one. The reason is that the Flex SDK integrates with OSMF APIs from a much earlier sprint, and in the latest OSMF SWC many of these APIs don't exist anymore (due to renaming).
And that's what I take seriously.
Yet, out of curiosity, and for the sake of exploration I took my chances and did replace the version of the OSMF that is shipped with the Flex 4.0 release with the latest - 0.95.
So far, all the functionality that I need - single player, multiple players, compiled in Flash, compiled in Flex, playing in synch, or alternating - seems working fine, including access to various events.
Let me repeat: this is NOT a suggestion; just mere sharing of experience, and it comes at a cost - you should use your versions of video player, i.e. built in that latest version of OSMF. The Spark VideoPlayer (or VideoDisplay) give you compile time error I mentioned before - TimeDimension.
Just FYI,
FTQuest

PLEASE HELP!! Need some way to read header text in advanced datagrid using QTP

I am writing a function to read column names in advanced data
grid. There is no operation for that and any of the properties that
I can use to read the column names.
Please suggest any way that I can get the names of columns in
the advanced data grid.
Thanks

I hope to hear something from adobe folks...I am providing
more info.....
I am using QTP 9.2 and Flex 3 add-in available from Adobe.
My application has flex Advanced datagrid object and I am
trying to read column names for the datagrid.
I have contacted developers and they told me that column
names for flex advanced datagrid are stored in "Header Text"
I have tried reading "Header Text" using
GetROProperty("HeaderText") but it doesn't return anything.
I have tried the following code:
x =
Browser("app").FlexApplication("flexapp").FlexCanvas("Canvas").FlexAdvancedDatagrid("esti mategridid").GetROProperty("Header
Text")
msgbox x
I have also tried getting value for column names using other
available properties for webtables like outerhtml, outertext, alt
etc. but I don't get any data.
Part of the problem may be because none of the above
mentioned properties are supported by Flex Advanced datagrid.
I have also tried getting child objects but I always get the
data in datagrid as values but not the column names.
My primary reason for getting column names is to write a
function to update cell in datagrid independent of application. So,
I want to pass column name as a parameter to the function and get
the corresponding columnIndex in the function by comparing the
parameter value against column names.
Thanks to all for you help...

HP QTP10 cannot read Automation values of Advanced DataGrid

Hi everyone,
We're an Automation functional testing team, testing a flex application with HP QTP v10. So far we've successfully automated many parts of the application. Now, we're struck at a serious issue.
The issue is QTP cannot read automation values specified for an Advanced Datagrid (ADG).
While trying to read row data of the ADG, the automation name of QTP shows like,
"lblData | someGroup | | ** | | | | | | | | | | lblData"
The screenshot of Object Spy while spying ADG is also attached.
Other than the Automation Index, we are not able to populate any automation values of a row data.
The ADG is a custom one. Our development team has customized it in some way, and we dont have access to the code. They are using an External renderer or Custom renderer to render values into the column.
As there is no possiblity for value-based recording, we tried to access the ADG with index-based recording. Then, we 're able to perform operations like Click, but cannot read contents of the row/cell.
We're using:
HP Quick TestProfessional v10.0
Flex plugin 4.5
Internet Explorer 7
Flash Player v10
Our Questions are:
How to get automation values for these custom ADG?
Is there any other possible ways to access the custom ADG components other than these automation values?
Do we need any patches/plugin upgradation to perform this?
Is there any other tools in market that can recognize and access these custom ADGs?
Without these automation values we're unable to proceed further work. Any replies/comments/help are welcome.
Thank you!

A sortCompareFunction would look something like:
Function sortWithNullAtEnd(a:Object, b:Object, field:Array = null):int
    if (a.fieldName == null && b.fieldName == null) return 0;
    if (a.fieldName == null) return 1;
    if (b.fieldName == null) return –1;
    if (a.fieldName < b.fieldName)
        return –1;
    if (a.fieldName > b.fieldName)
        return 1;
    return 0;
Note that this sort would be unstable so you might be better off using a second field to get stability.

(Advanced)DataGrid with selectable columns

Hello -
I'm trying to make a Flex (Advanced)DataGrid component with some mechanism where the user can toggle the visibility of the columns. I've crudely implemented this by reading in the columns into the right-click menu, and when a column name is selected here, the visibility is toggled. It works, but it's not the most elegant solution.
Specifically, I'm trying to emulate the "datagrid" that Mozilla Thunderbird uses to display emails. Here is an image:
In the upper right, there is an icon over the scroll bar. If there is no scrollbar, the icon remains in the same place. When clicking the icon, it opens up a menu that shows all the possible columns, with the visible ones having a check mark next to them, like this:
Also, the scroll bar always appears under this button, never "pushing" it over into it's own column.
I'd like to re-create this in Flex. I believe the menu part and creating a column with a button headerRendered is easy enough. But I can't figure out how (if at all possible) to do this with the scrollbar, because the scrollbar always seems to be "its own column". Any ideas or help would be appreciated. Thank you.

Parent Tree
   Expanded1
      Expanded2
          Expanded3
                 ParentTree

value
Expected tree structure in advanced datagrid :
Header 1
Header 2
Header 3
Header 4
Header 5
ParentTree
Expanded1
Expanded2
Expanded3
value
can someone tell me if this is possible in advanced data grid and if possible please let me know how do i expand the tree icons in seperate columns ...
Thanks ,
Ajantha

Hi,
you can check the view source of html and check the onclick code written on that plus sign(Expand All), just copy that onclick javascript code and put it on page javascript event.

Mx_internal_uid problem with advanced datagrid

I have a XML structure like this:
<Projekti ...attributes>
<Tehtava ....attributes />
<Tehtava ...attributes />
</Projekti>
<Projekti...>
...etc
And I'm populating advanced datagrid with this hierarchial
data, so I can get a tree view in datagrid where there is Projekti
-nodes and inside them is the Tehtava-nodes.
Problem:
When I bind the XML, and the hierarchialdata (that is created
from the XML) flex automatically adds
<mx_internal_uid>a324235351514......</mx_internal_uid>
-nodes inside of the Projekti-nodes. And this causes empty folders
added in a tree view when user clicks them.
Is there a simple way to:
a) prevent thos uid-nodes being created?
b) filter thos <mx_internal_uid>-nodes out from the
dataprovider of the advanced datagrid?

I know this is way after-the-fact, but I just ran into this problem myself today. I found that it generated the mx_internal_uid if the node I was selecting was an XMLList instead of XML. A simple cast fixed the problem.
P.S. "And this causes empty folders added into a tree view when user clicks on them." makes perfect sense when you're using the XML inside a <mx:Tree>. As soon as you select the item (whether by clicking or programmatically), you get extra nodes in the tree.

Drag and Drop in DataGrid/Advanced DataGrid

Hi All,
Here is the scenario, assume that i have some 10 records in
DataGrid/Advanced DataGrid .I have selected 4th record and when i
try to drag the selected item to
down, i should be able to drag all the records one step down
from the selected record( from 4 th record to 10th record)
i.e, re-arranging the items
If i drag the selected item(assume that some 6th record) to
top, say to 2nd row then from the second row all the rows
has to come down.
And How do we
add the rows at middle and at the specified position?
Any help will be appricated and Thanks in Advance.

Hi All,
myself got the solution for re-arranging the datagrid items
by using the pre-defined properties of DataGrid.
I can also get the index number of Items while start dragging
but the problem is how do i get the index number where the Items
dropped.
Here is the code..............

Grouping of Data in Advanced Datagrid

Hii,
I need to group the data in advanced datagrid. I used the Grouping collection class, but it it not working.
My advanced datagrid has column groups...so will this have any impact on grouping.
Thanks!!

Assuming that the table (say WALK_IN_PER_LOG) that you have has atleast the following two columns
walk_in_date DATE -- holds date time stamp
dob DATE -- holds date of birth
SELECT TO_CHAR(walk_in_date,'WW')| |'-'| |TO_CHAR(walk_in_date,'DAY') "Week#-Day"
,TO_CHAR(TRUNC(TO_CHAR(walk_in_date,'HH24')/02),'09')| |'-'| |
TO_CHAR(TRUNC(TO_CHAR(walk_in_date,'HH24')/02)+2,'09')
,COUNT(*)
FROM walk_in_per_log
WHERE MONTHS_BETWEEN(SYSDATE,dob) > 18*12
GROUP BY TO_CHAR(walk_in_date,'WW')| |'-'| |TO_CHAR(walk_in_date,'DAY')
,TO_CHAR(TRUNC(TO_CHAR(walk_in_date,'HH24')/02),'09')| |'-'| |
TO_CHAR(TRUNC(TO_CHAR(walk_in_date,'HH24')/02)+2,'09')
PS I might have complicated the query a little in trying to get the formatting as you had requested but the principle is simple
First group by the day, so that all events of one day can be compared together, then extract the hour portion of each of those dates and divide by 2 and use the quotient of the division as a grouping factor.
eg
from hours
00-02 the quotient is 0 (2 is taken as 1:59:59)
02-04 the quotient is 1 (4 is taken as 3:59:59)
and so on
hope this helps....

Grouping issue on Advanced DataGrid

Hello,
I've got an advanced datagrid with 5 columns, The number_Group column has data like this...
1-10
1-10
11-20
11-20
11-20
21-30
21-30
21-30
41-50
101-110
When I apply Grouping, it works as expected but the 101-110 group is displayed before the 11-20 group.
I've tried to set groupingField.numeric = true but that screws it up even more... because 11-20 isn't a number I'm guessing.
Does anyone know a way around this? I could change the number_Group column to this...
1
1
11
11
21
41
101
and groupingField.numeric = true should work but I need the Grouping display to show 1-10, 11-20. Perhaps I can intercept this and modify it?
Anyone got any ideas?
Thanks,
Nick

Hi, Nicky
u can solve this problem by grouping function.
u create ur dataprovider like
private var myData:ArrayCollection = new ArrayCollection([{data1:1, data2:10,......},
{data1:1, data2:21, ....}]);
u declare the grouping function in following manner
private function myGroupLabelFunction(item:Object, column:AdvancedDataGridColumn):String
// here u write ur logice to formatting ur dispalying data in advance grid.
//suppose ur labelfield of datagrid are data1,data2, data3 respectively.
return item.data1+"-"+item.data2;
if u do in this way i think it will work.
if u sucess then give me mark.
Thanks
