RE: [flexcoders] Singletons and Modules - Application domain problem
When you optimize a module, classes are removed from the module and must be found in the parent applicationdomain. For me, if I then load the module into an app that doesn't supply the missing classes, I see verify errors, but some folks seem to see nothing, just silent failure. So first, you have to make sure required classes exist in the module or in its parent applicationdomain. Then, once you get it to load, further requests to load the same URL will just be ignored and the same factory is returned. That means all instances created by the factory will be from the same appdom and share singletons. To not share, you can try adding fake params to the url. That should generate a separate child appdom with its own singletons as long as those classes aren't inherited from the parent appdom.

Your code probably does this: var somObj:SomeInterface = module.factory.create as SomeInterface So the as returns null. With modules you must use a child applicationdomain i.e. new ApplicationDomain(applicationDomain.currentDomain) so that the interface is shared. The next trick is to get the ModuleManager to attempt a second load in a separate child applicationdomain so fake url params might work. As long as the singletons are not in the main app, each child appdomain should have its own singleton.

[flexcoders] Capturing URL Requests in AIR application (HTML/HTMLLoader/HTMLHost)
Hi, This post is quite lengthy, but I really need to explain in detail what it is I'm trying to achieve here. I am developing an AIR application that has an mx.controls.HTML component as the only child; in essence the application is a custom web browser in AIR. I have created a custom HTMLHost component that extends the flash.html.HTMLHost class per the Adobe documentation, so that my application can intercept particular JavaScript calls; i.e. (AS)createWindow() - (JS)window.open(). The main HTML component has its htmlHost property set to an instance of this CustomHTMLHost class, and every new window that is created via the createWindow() method also has its htmlHost set to an instance of the CustomHTMLHost class. In my CustomHTMLHost class, I also override the updateLocation(locationURL:String) method, enabling me to inspect the new URL that is being set on either the main HTML component, or any popup windows that are created. The web application I am loading into the main HTML component allows users to export reports in a number of formats (HTML, PDF, XLS, CSV, TXT) which can either be opened or downloaded when using a conventional browser (IE/FF/Safari). When the user exports a report, a popup window is displayed (which works fine with my application because of the overridden createWindow() method in the CutsomHTMLHost class). After the user clicks the final Export button on a PDF/HTML/TXT export, everything works fine and the report results are displayed as the AIR runtime can handle these files. However when the user exports to XLS/CSV nothing happens, which is expected because the AIR runtime does not support those file types. I intend to create a file download manager to handle this so that the user can just save the files to their local file system, and this is where I'm hitting a brick wall. I am able to capture the URL that is being requested to get these latter export types from the overridden updateLocation(locationURL:String) method in the CustomHTMLHost class, but the URL alone is not enough information for the AIR application to send to the web application that provides the report exporting functionality. I need to get access to the rest of the header information (such as POST variables, and also the cookie information) that is sent in the HTTP request when the final Export button is clicked by the user to ensure I am getting a valid response from the web application. So, to finally get to my main question... is there any way to intercept the URLRequests that are created and invoked from a HTML/HTMLHost component? What I really want to be able to do is to inspect the HTTP responses, so that I can determine content of the HTTP response i.e. Content-Disposition: filename*=Report.xls; Content-Type: application/vnd.ms-excel; charset=UnicodeLittle With this information I can let my AIR application display a save file dialog or something along those lines. Sorry for the long post, and any help would be appreciated as this is a critical part of my AIR application, and I REALLY need to figure this out. I understand that the approach I am proposing may not even be possible, as I have been doing a number of things to try and solve it. One of which was extending the HTMLLoader class and overriding the load(urlRequestToLoad:URLRequest) method to I could intercept all URLRequests, but I couldn't even get the HTML component that used this class as its htmlLoader property to load any HTML content.

[flexcoders] Tree Control Populating from Database via XMLListCollection
Hi FlexCoders,
Am currently working on a Tree control, and being my first time to delve into
this, I need your inputs and advice.
My tree control is retrieving data from a .NET web service. My .NET webservice
returns a string which is parsed from a dataset via the command DataSet.GetXML
method.
In my flex application, I am converting the string value returned by the
webservice into an XML:
private var _xmlMyData:XML;
private function myResultHandler(event:ResultEvent) :void
{
_xmlMyData = XML(event.result);
// This script to view the XML data in Text Area
var strData:String = String(event.result);
taData.text = strData;
}
Which I am then passing to my xmlListCollection control
mx:XMLListCollection id=xmllc_myData source={_xmlMyData.Table} /
mx:TextArea id=taData width=300 height=100 /
Then binding to my tree control:
mx:Tree id=treeOffshore dataProvider={xmllc_myData} labelField=DESCN
showRoot=false
/mx:Tree
When viewing the data in the text area control, I have the following:
NewDataSet
Table
CODEA1/CODE
DESCArea One/DESC
/Table
Table
CODEB2/CODE
DESCBase Two/DESC
/Table
Table
CODEC4/CODE
DESCClass Four/DESC
/Table
Table
CODED8/CODE
DESCDemo Eight/DESC
/Table
/NewDataSet
This is how the treeview renders:
Area One
A1
Area One
Base Two
B2
Base Two
Class Four
C4
Class Four
Demo Eight
D8
Demo Eight
What I want is to be able to define the Description only at the first level
only:
Area One
Base Two
Class Four
Demo Eight
The next thing that I need to accomplish is that the second level of the
treeview should actually be populated based on the CODE from the first level.
For example:
Area One
Sub Item Area One
Sub Item Area Two
Base Two
Sub Item Base Two
Sub Item Base Three
Sub Item Base Four
Class Four
Sub Item Class Four
Demo Eight
Sub Item Demo Eight
Sub Item Demo Nine
Sub Item Demo Ten
Sub Item Demo Eleven
The sub-items would be retrieved from the database based on the parent code
(i.e Demo Eight = D8, Class Four = C4... etc.)
I am quite new in this tree control thing (as well as flex) and have limited
grasp of the concepts to be able to accomplish this.
I am thinking either of modifying the XML data which I originally retrieve and
probably insert the sub items per each node, although I am in a bind of how to
accomplish the same.
On the other hand, to give some of you further details, the treeview data would
actually be coming from three tables where the table 1 is the base table, and
the table 2 contains the children of table 1 and table 3 contains children data
from table 3. I think I can manage to make one SQL statement to be able to
retrieve the data for the whole treeview but I think that would be very
complicated especially in the part where parsing the XML goes.
I would sincerely appreciate your inputs on this. I am foraying into the world
of Flex and this is quite a make or break scenario towards embracing this
technology in our organization.
Thanks and hoping to hear from all of you soon.

Angelo

[flexcoders] Flex Datagrid -Extract non formatted (raw) value onItemEditBegin
Hi there, I have an Advanced Data Grid (Flex) and I am showing numeric values. I am formatting each value by using a labelFunction, which returns a currency formatted value (using a currency formatter). Let's say the dataprovider holds the value 1000 for the first element. The first cell of the datagrid will then show $1,000 Now, if I click into a cell, and start the editing process, I only want to see 1000, not $1,000. I can not set the itemEditorInstance.text property to the value in the datagrid onItemEditBegin, since the itemEditorInstance is only created afterwards. How would I accomplish this then?

I am developing an AIR application that has an mx.controls.HTML component as the only child; in essence the application is a custom web browser in AIR. I have created a custom HTMLHost component that extends the flash.html.HTMLHost class per the Adobe documentation, so that my application can intercept particular JavaScript calls; i.e. (AS)createWindow() - (JS)window.open(). The main HTML component has its htmlHost property set to an instance of this CustomHTMLHost class, and every new window that is created via the createWindow() method also has its htmlHost set to an instance of the CustomHTMLHost class. In my CustomHTMLHost class, I also override the updateLocation(locationURL:String) method, enabling me to inspect the new URL that is being set on either the main HTML component, or any popup windows that are created. The web application I am loading into the main HTML component allows users to export reports in a number of formats (HTML, PDF, XLS, CSV, TXT) which can either be opened or downloaded when using a conventional browser (IE/FF/Safari). When the user exports a report, a popup window is displayed (which works fine with my application because of the overridden createWindow() method in the CutsomHTMLHost class). After the user clicks the final Export button on a PDF/HTML/TXT export, everything works fine and the report results are displayed as the AIR runtime can handle these files. However when the user exports to XLS/CSV nothing happens, which is expected because the AIR runtime does not support those file types. I intend to create a file download manager to handle this so that the user can just save the files to their local file system, and this is where I'm hitting a brick wall. I am able to capture the URL that is being requested to get these latter export types from the overridden updateLocation(locationURL:String) method in the CustomHTMLHost class, but the URL alone is not enough information for the AIR application to send to the web application that provides the report exporting functionality. I need to get access to the rest of the header information (such as POST variables, and also the cookie information) that is sent in the HTTP request when the final Export button is clicked by the user to ensure I am getting a valid response from the web application. So, to finally get to my main question... is there any way to intercept the URLRequests that are created and invoked from a HTML/HTMLHost component? What I really want to be able to do is to inspect the HTTP responses, so that I can determine content of the HTTP response i.e. Content-Disposition: filename*=Report.xls; Content-Type: application/vnd.ms-excel; charset=UnicodeLittle With this information I can let my AIR application display a save file dialog or something along those lines.

[flexcoders] VBox constrains - A simple question :-p
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; width=640 height=480 mx:VBox top=100 bottom=10 horizontalCenter=0 width=90% horizontalAlign=left verticalGap=5 id=debugWinVB_ID /mx:VBox /mx:Application At the start of the application the VBox height is 370 (Application.height - vbox.top - vbox.bottom) - Correct. Child labels are added to this vbox in runtime and as soon as the cumulative labels height becomes 370 the vbox expands and scroll bars appear @ the Application level...Why? Should not the Vbox remain @ 370 height and display inner scrollbars, according to the following rule:? * Component size determined by a pair of constraint-based layout properties (left-right or top-bottom) overrides any explicit or percentage-based size specifications. For example, if you specify both left and right constraints, the calculated constraint-based width overrides the width set by a width or percentWidth property.

[flexcoders] Re: Module and Application Communication.
So I was going to make you a sample app to show you what was wrong, but then it
was working. Then I looked at my code and again and realized I was actually
dispatching the event in a popup that was created inside that module. So let me
change the question!
Is it possible to catch an event in the main application dispatched by a Popup
in a module, by adding an event listener to the instance of the module you
added to the stage! Cause I can't get that to work :(

Re: [flexcoders] Re: ComboBox not updating
My solution (which is not a general one) appears to be avoiding using a

mx:ComboBox xmlns:mx=http://www.adobe.com/2006/mxml;
dataProvider={this.availableOperators}
selectedIndex={findSelectedIndex(this.selectedOperator,
this.availableOperators)}
I have custom custom setters for selectedOperator and availableOperators,
and update selectedIndex in those.

Re: [Spam] Re: [flexcoders] Fields grouping?
Tim and Wesley, thanks for your replies... really appreciate it. I've not been flexing for long so that's for helping me out... I treid using forms with a border and using a formheader but it didn't give the look I was after. I guess i can change my UI designs if needed though but I though the field grouping thing was a standard object in most development environments... I think the Panel will give me the best enclosure feel... One thing I've noticed about Forms is that they're great for vertical layouts but if I want to have fields side by side then I need to use two forms and then second having a blank header to force the first field to be lined up with the field in the first Form.

[flexcoders] Re: weird NumericStepper question / script
I was looking for a way to create a no-maximum NumericStepper and came up with
the idea of listening to the Change event and just upping the maximum value by
1-stepSize unit above the current value.
The only thing was, I needed to use a callLater() in order to change the
maximum or else the change didn't take effect in time.
So I would suggest a listener on each, in which you would calculate the new
maximum of the other two steppers, then perform a callLater that looks like
this:
callLater(resetMaxValues, [newMaxValue, stepperA, stepperB])
... and then something like this:
private function resetMaxValues(newMaxValue:int, stepperA:NumericStepper,
stepperB:NumericStepper):void
{
stepperA.maximum = newMaxValue;
stepperB.maximum = newMaxValue;
}

Subject: [flexcoders] weird NumericStepper question / script
I've got 4 NumericSteppers; and the problem I'm having is one I can't
get my head 'round: the values of all the NumericSteppers have to add
up to 100.
On the whole I could easily check via a 'submit' button if they don't
addup, but I'd like to check on any of the stepper's 'change' function
-- what I was thinking was:
As a one is going up, the maximum of all the others goes down in a
cycle (ie if someone is putting numB, then C then D -- they're max
slowly goes down.
If the max value of a numeric stepper meets the current value of that
stepper, and there's no more 'room' -- then the user can't keep
increasing the size of the current numeric.
Is this making sense? In other words, how does one tie in the value of
one stepper with another to equal 100. Sure, having 2 steppers makes
it easier somewhat, but with 4 I don't know how best to pay attention
to them all while still keeping the numbers validating.
I'd appreciate any thoughts.

[flexcoders] 5 Datagrids ontop of each other, one resizes and the ones below shift up or down?
Hi guys, Excuse the subject of this post :-) But it does sum up what I'm trying to achieve. I want to have 5 DataGrids ontop of each other in a vertical arrangement (A bit like the rows in Excel are ontop of each). In the bottom right of each DG, I want a little button that when clicked, expands/ collapses it's DG. When e.g. DG_2 is expanded, I want DG_1 to remain where it is but DG_3, DG_4 and DG_5 to shunt downwards and DG_2 will be expanded down to say ten rows. What is the best way to achieve this? Or should I be looking into DividedBox components? Or does the Tile Component help me? Or do I write it all myself using maths and do the resizing using top and bottom properties of the DG's? Thanks for any help... Nick
[flexcoders] Re: NumericStepper no maximum value
I was looking to do the same thing ... came up with this:
numericStepper.addEventListener(NumericStepperEvent.CHANGE,
function(event:NumericStepperEvent):void {
callLater(resetMaximumValue);
});
... and then a function like this:
private function resetMaximumValue():void
{
numericStepper.maximum = numericStepper.value + numericStepper.stepSize;
}
... inflates the maximum value one stepSize above whatever the current value
is. The callLater is the key, since timing can screw this up. It seems to work
for me, but I haven't thoroughly tested it beyond what I made it for.

Re: [flexcoders] ImageSnapshot without scroll bars?
Never printed anything from flex back you could either: 1) remove scrollbars prior to printing and then put them back (horizontal and vertical scroll policies set to off) 2) if this makes the application 'jumpy' due to bars disappearing and then reappearing, you could possibly try and copy the contents of the container to an offscreen copy of it with scroll policies set to off and print this (no idea if you can print offscreen containers, cannot imagine why not but then again...)

Hey Fotis, I've tried all that and yes, if I resize the container according to it's children, then remove the scroll bars, it does allow me to take an ImageShapShot that is the correct size height and width.

Subject: [flexcoders] Tree Control Populating from Database via
XMLListCollection
Hi FlexCoders,
Am currently working on a Tree control, and being my first time to delve
into this, I need your inputs and advice.
My tree control is retrieving data from a .NET web service. My .NET
webservice returns a string which is parsed from a dataset via the command
DataSet.GetXML method.
In my flex application, I am converting the string value returned by the
webservice into an XML:
private var _xmlMyData:XML;
private function myResultHandler( event:ResultEven t) :void
{
_xmlMyData = XML(event.result) ;
// This script to view the XML data in Text Area
var strData:String = String(event. result);
taData.text = strData;
}
Which I am then passing to my xmlListCollection control
mx:XMLListCollectio n id=xmllc_myData source={_xmlMyData .Table} /
mx:TextArea id=taData width=300 height=100 /
Then binding to my tree control:
mx:Tree id=treeOffshore dataProvider= {xmllc_myData} labelField=
DESCN showRoot=false
/mx:Tree
When viewing the data in the text area control, I have the following:
NewDataSet
Table
CODEA1/CODE
DESCArea One/DESC
/Table
Table
CODEB2/CODE
DESCBase Two/DESC
/Table
Table
CODEC4/CODE
DESCClass Four/DESC
/Table
Table
CODED8/CODE
DESCDemo Eight/DESC
/Table
/NewDataSet
This is how the treeview renders:
Area One
A1
Area One
Base Two
B2
Base Two
Class Four
C4
Class Four
Demo Eight
D8
Demo Eight
What I want is to be able to define the Description only at the first level
only:
Area One
Base Two
Class Four
Demo Eight
The next thing that I need to accomplish is that the second level of the
treeview should actually be populated based on the CODE from the first
level.
For example:
Area One
Sub Item Area One
Sub Item Area Two
Base Two
Sub Item Base Two
Sub Item Base Three
Sub Item Base Four
Class Four
Sub Item Class Four
Demo Eight
Sub Item Demo Eight
Sub Item Demo Nine
Sub Item Demo Ten
Sub Item Demo Eleven
The sub-items would be retrieved from the database based on the parent code
(i.e Demo Eight = D8, Class Four = C4... etc.)
I am quite new in this tree control thing (as well as flex) and have limited
grasp of the concepts to be able to accomplish this.
I am thinking either of modifying the XML data which I originally retrieve
and probably insert the sub items per each node, although I am in a bind of
how to accomplish the same.
On the other hand, to give some of you further details, the treeview data
would actually be coming from three tables where the table 1 is the base
table, and the table 2 contains the children of table 1 and table 3 contains
children data from table 3. I think I can manage to make one SQL statement
to be able to retrieve the data for the whole treeview but I think that
would be very complicated especially in the part where parsing the XML goes.
I would sincerely appreciate your inputs on this. I am foraying into the
world of Flex and this is quite a make or break scenario towards embracing
this technology in our organization.
Thanks and hoping to hear from all of you soon.
Regards,
Angelo

Hi everyone, I'm having an issue with my tree component. I use an arrayCollection for my dataProvider. I have the same object in my arrayCollection nested at different levels. I cannot select this object at different levels in my tree, it always select the topmost nested object. Is there a way to work around this? I would like to be able to select an item even though the same item is found at different nested levels within the tree. Thanks!
