[flexcoders] custom context menu on ADG crashes IE and FF - advice please
On a custom AdvancedDataGrid - did the standard thing to add a total footer - I have a column where the item renderer puts a hyperlink/link button in the grid cell. I attached a custom context menu to this link button with custom menu item. Selecting this menu item shuts down IE or FireFox immediately. I have removed the menu item listener so it does not try and go anywhere,but the browser still shuts down when - right-click gridcell which is a link button to display context menu - select custon menu item - browser quits. Any advice on this one would be greatly appreciated. TIA, Mic.
Re: [Spam] [flexcoders] Re: Memory leak with Data Grid and Item Renderers
Hi, There doesn't seem to be a removeAllChildren() method of the Advanced Data Grid. Also, when I test test the numChildren property it only gives me 4 but I've got a renderer (child) for each of the 9 columns over 20 rows = 180... I've just found a rendererArray which is an Array of Arrays for the renderers for each row/Column... I'm hoping I may be able to delete the 'children' this way? have you ever used this property? or perhaps there's another way to delete the 'children' of the Adv Data Grid? Thanks, Nick 2009/11/6 valdhor valdhorli...@embarqmail.com I don't think you can do that. Item renderers are created automatically. If it were me, I would probably removeAllChildren from the datagrid and add each column again. This should create new renderers as required.

Re: [flexcoders] Passing values from popup window to MXML component
You can add a logout button at the same place as login button and toggle
the visibilities of these buttons depending upon the
state of your component.

you can use the list's properties (arrays of indices, or items):

[flexcoders] How to configure flex app in HTTPS load balanced environment where app servers serve http requests
Hi,
I have developed the dashboard in my application using flex 3.0. For this I
have used JSP wrapper around the flex application. My application runs on
JBoss application server. For communication between flex app and my
application I am using LCDS. HTTPService component is being used to receive
data from the server. Channel definitions are given in service-config.xml
for secure amf and secure http channels. In my proxy-config.xml I have
defined Channels and destinations.
In my development environment both secure and non secure mode were working
fine.
Now in my test environment I have deployed it behind the hardware load
balancer(which accepts secure requests only and if the request is not secure
it redirects it to secure url).
So the load balancer only accepts HTTPS URLS and after that the request is
converted into HTTP and sent to web/app servers
I am getting following exception
06:06:13,521 INFO [STDOUT] [LCDS][ERROR] Exception when invoking service

Re: [flexcoders] Passing values from popup window to MXML component
Yeah you can do what rohit said by adding a logout button at the same place and
toggling the visiblity.
This way,
From you main application you can do something like this.
if(loginWin. userInput. text=='funandlearning' loginWin.passwordIn
put.text= ='funandlearning')
{
Alert.show(Login Successful);
loginWin.loginButton.visible = false
loginWin.logoutButton.visible = true
}
You can also use the same button but play around the text property.

At the instance or global level of an mxml file, you can only

the value by using a ceeationComplete handler.
Now, mx:Form is just a layout container, and won’t process the field
data for you in any special way. You will need to get the value
from each form item control individually, and build the string you
want. (or, if the form changes update a model, use the model.)
Right, so what I had built thus far is:
private var mailMe:String = mailto:kear...@gmail.com?subject=answersbody=
;
private function sendEmail():void
{
navigateToURL(new URLRequest(mailMe + unNaturalText_1.text +
unNaturalText_2.text),'_self');
}
It's working well now except that there's no separation between each
text block from each TextInput instance in the email output. I'm
trying to put each text block in its own paragraph. I've tried
inserting \n and \r in various combinations with + and the .text
instances. None of those thus far works to separate the text blocks
into their own paragraphs. What am I missing?
Is there good reason to use a model for this situation?
Tracy, I appreciate your patience, persistence and teaching.

[flexcoders] Adobe AIR 1.5.1: issue on opening encrypted DB
Hi all, I got a sqlite DB that's encrypted with AES256 using sqlite3 command line tool: sqlite3.exe -key test123Test test.db I able to do this encryption because I bought the SEE license. And I did test that the encryption does work, I could not view the DB content directly using the DB Admin Tool I have but I could view the content using the sqlite3 command line tool. I believe the reason why my DB Admin Tool couldn't work because it doesn't have the SEE license. Anyway, I tried to open this with ADOBE AIR and I did make sure passing the encryption key as part of the argument. But what I got is an error msg: Error message: Error #3125: Unable to open the database file. Details: An encryption key cannot be specified when the database is not encrypted. So this brings me to this question: - What kind of SQLite encryption does ADOBE AIR really supports? - Does ADOBE have SEE license? Please enlighten me. Thx!

[flexcoders] Need clarifications about ArrayCollection and binding
Hi,
Question 1:
There is note in Adobe Flex 3 help
(http://livedocs.adobe.com/flex/3/html/help.html?content=databinding_4.html):
Note: [..] the ArrayCollection class dispatches an event when the array or the
array elements change to trigger data binding. For example, a call to
ArrayCollection.addItem(), ArrayCollection.addItemAt(),
ArrayCollection.removeItem(), and ArrayCollection.removeItemAt() all trigger
data binding.
And there (in documentation) is example, where mx:List is used with
`ArrayCollection` as data provider, which should confirm this note.
But my experience shows, that it's invalid (or I misunderstand something).
IMHO, `ArrayCollection.addItem()` (and co.) doesn't trigger data binding (and
it's only triggered when reference changes). And mx:List handles manually it
(it registers event listener for CollectionEvent.COLLECTION_CHANGE when
`dataProvider` is set) - so it may appear like it was binding stuff.
Is this note wrong? Incomplete? Or maybe I misunderstood something?
Question 2 (and it complements question 1):
I have model class with property `list`:
[Bindable]
public var list:ArrayCollection;
I want to reconstruct internal (in MXML) list, when list in model changes
(reference changes, or item is added/removed). In MXML component I have
something like this:
[Bindable]
public var model:Model;
/* this is called on `creationComplete` */
private function initLocal():void
{
model = new Model();
BindingUtils.bindSetter(constructList, this, [model, list]);
}
But `constructList` is called only once (in my case, only when reference
changes). As I understand, bindings doesn't work when adding/removing items and
I should manually listen for CollectionEvent.COLLECTION_CHANGE?
(third question/issue)
If I change `list` property in `Model` to manual binding:
[Bindable(event=listUpdated)]
public function get list():ArrayCollection
{
...
}
And when manually dispatching `listUpdated` events (when item is added/removed,
or list reference changes), then `BindUtils.bindSetter()` works as I expect -
`constructList` is called when item is added, etc.
Question: why this differs from default binding ([Bindable])? I assume, that
default bindings doesn't fire `propertyChange` event, when something is added
to ArrayCollection. Am I right?

[flexcoders] Get Notified if a Remoting Result event listener function *doesn't get called?
This sounds vague, but basically it's: My Zendamf remoting object has a fault=faultListener(event), which has an Alert.show statement. However, I noticed that when I'm on my laptop, and my Net connection is flakey, this happens: I create a new Item that then gets added to my List object successfully, and the next step is to add to the database on the Server-end, so I call: myRemote.addNewTask(tempTask); But there's no feedback , and although I see the new Item in my List this only means the Client side succeeds, but the DB save silently fails without a Fault event. I have a Result event set up, but the resultListener function never gets called. It's not like I can do this: if (!succeeds) then display fail, like you can on a normal php/mysql app. And I just want to avoid having to go the reverse logic route to resolve this: When the Result event gets called, do an Alert.show(). Don't want to have to click OK everytime it's successful. ;/ Just wondering how anyone else handles this, Thanks, Steve

Now, mx:Form is just a layout container, and won’t process the field data
for you in any special way. You will need to get the value from each form
item control individually, and build the string you want. (or, if the form
changes update a model, use the model.)
Right, so what I had built thus far is:
private var mailMe:String =
mailto:kear...@gmail.com?subject=answersbody=kear...@gmail.com?subject=answersbody=
;
private function sendEmail():void
{
navigateToURL(new URLRequest(mailMe + unNaturalText_1.text +
unNaturalText_2.text),'_self');
}
It's working well now except that there's no separation between each text
block from each TextInput instance in the email output. I'm trying to put
each text block in its own paragraph. I've tried inserting \n and \r in
various combinations with + and the .text instances. None of those thus far
works to separate the text blocks into their own paragraphs. What am I
missing?
Is there good reason to use a model for this situation?
Tracy, I appreciate your patience, persistence and teaching.

RE: [flexcoders] Need clarifications about ArrayCollection and binding
1) That example could be better. You are correct that List listens
directly to collectionChange events and doesn't use the binding subsystem.
That's because it wants more information about what changed so it can optimize
updating. But ArrayCollection does dispatch PropertyChangeEvents when you call
addItem, etc and that should be enough to update the binding subsystem
2) BindSetter just watches for a event associated with a setter. It does
not watch for changes internal to the value of that property.
3) When you detect internal changes yourself and dispatch the setters
associated event that will work since it fires the event that BindSetter is
watching for.
Binding basically watches events at various levels on a property chain a.b.c.
The problem with AC is that, you can bind to a property like length, but you
can't bind to elements without using a function expression like getItemAt(0).
You can try binding using {model.list.getItemAt(0)} and see what watchers the
compiler generates. That might help you figure out how to set it up from
actionscript, but you might be better off just using {} binding expressions if
you can.

Subject: [flexcoders] Need clarifications about ArrayCollection and binding
Hi,
Question 1:
There is note in Adobe Flex 3 help
(http://livedocs.adobe.com/flex/3/html/help.html?content=databinding_4.html):
Note: [..] the ArrayCollection class dispatches an event when the array or the
array elements change to trigger data binding. For example, a call to
ArrayCollection.addItem(), ArrayCollection.addItemAt(),
ArrayCollection.removeItem(), and ArrayCollection.removeItemAt() all trigger
data binding.
And there (in documentation) is example, where mx:List is used with
`ArrayCollection` as data provider, which should confirm this note.
But my experience shows, that it's invalid (or I misunderstand something).
IMHO, `ArrayCollection.addItem()` (and co.) doesn't trigger data binding (and
it's only triggered when reference changes). And mx:List handles manually it
(it registers event listener for CollectionEvent.COLLECTION_CHANGE when
`dataProvider` is set) - so it may appear like it was binding stuff.
Is this note wrong? Incomplete? Or maybe I misunderstood something?
Question 2 (and it complements question 1):
I have model class with property `list`:
