[flexcoders] Is there a separator item for a ComboBox?
Hi, Does the flex standard library have a separator (horizontal line) item that you can specify to insert into a ComboBox? I looked around, doesn't seem to be one, but I thought I'd ask around here as well. thx, George -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Web site design development Computer software development Software design and development Macromedia flex Software development best practice YAHOO!

[flexcoders] Re: Hardware requirements for Flex performance
thanx for the response Mika. I was wondering if you have even experiences behavioral anomalies as a result of this? For instance, when I select a lot of data from this popup window, it displays in my main window as an iteration of Repeater tags. Problem is that some of my selections aren't being displayed. Just a little baffled at that.

[flexcoders] Re: Component that has event listeners and handles it's own event
Thanx Gordon, that is what it appears to be.
However I thought of a different workaround to address this. I just
have the combobox that handles its change event. It would then
dispatch a new custom event in which other components could receive
and handle. That would ensure the ordering of events I want I believe.

In Flex 1.X, dispatchEvent() is implemented in AS2 using a for-in loop
over an Object holding all the listeners. I think AS2 didn't technically
guarantee the for-in order for an object's properties, but I believe the
player's implementation actually consistently enumerated them in the
reverse order that they were added.
So in 1.X, it may be that the order in which event listeners get called
is always the reverse of the order in which addEventListener() added
them.

[flexcoders] Re: problem with cell renderer in ComboBox
Just sharing the solution I got for this with Flex Support. I
basically just used the labelFunction attribute.
mx:Script
function formatName( item ) : String {
return item.firstName + + item.lastName;
}
/mx:Script
mx:ComboBox id=employeeComboBox labelFunction=formatName
dataProvider={ModelLocator.employees}
/
I still wondering why the cellRenderer solution didn't work.

Hi Matt,
You have an example of a labelFunction? Say I have the blurb below...

funtion foo() {

}
/mx:Script
mx:ComboBox id=employeeComboBox
labelFunction=foo
rowCount=10
mx:dataProvider
{ ModelLocator.employees }

Here, ModelLocator.employees is an array of custom vo objects. How
do I access the individual attributes of each vo object in this scenario?

[flexcoders] Re: How to handle sessions in Flex
thanx for the prompt reply. I neglected to mention some other requirements. The nature of our app can have our users spends a good deal amount of time filling out the form. There's a save button there to save your work. However say the user is filling out the form and doesn't bother to save the form. There's a good chance that the session could expire before he gets a chance to save the form. Our server session is usually 30 minutes. In this scenario, when the session expires, we don't want the user to lose the data on the form. We want to somehow catch the session timeout and save the form. Another scenario we want to catch is, say you logout. The session is invalidated. However you could hit the browser Back button and have the previous screen display. You wouldn't know that the session time out until you invoke a service call. Instead I want to go to the login screen in such a scenerio. Can this be done?

[flexcoders] Re: Need help in tackling this event problem...
Hi,
We are using commands. The command has access to this when the event
is broadcasted. It's the event that you get on onResult(event) and
onFault(event) that doesn't have this data. event.data and event.type
are undefined as well.
We thought about the global variable route. Actually we thought about
having the Responder having an attribute for this as well. Problem
with that though is that we have asynchronous chained commands for
certain actions and there's no way to know which data is relevant to
which command any any point in time.

Hi,
The simplest solution is to implement commands :)
However, if you want to keep what you have, you will have to save the
original event object in some global variable so that you can look it up
once onResult() or onFault() are fired.

Subject: [flexcoders] Need help in tackling this event problem...
Hi,
Here's my scenerio:
I have a view and it's corresponding ViewHelper. There are two
buttons in the view. If I hit button A, I want action X to occur. If
I hit button B, I want action Y to occur.
This is how I broadcast my event in this view when I hit these buttons.
CommandEventBroadcaster.getInstance().broadcastEvent(SharkfinControl.EVE
NT_SAVE_FORM,
{form: true}, this);
We have a custom EventBroadcaster that we wrote to include the
Responder object (the 'this' argument). It's also passing in a boolean
flag here (form). In our case the ViewHelper
implements the Responder interface. This is for the purpose
decoupling the command from the Responder (ViewHelper). In our
Responder we have the onFault(event) and onResult(event) methods in
which we do post-command-execution stuff.
The problem it seems for me is that I want to have some sort of flag
that would distinguish between executing action X or Y (the form
boolean). I can set a flag when broadcasting the event. The command
class has access to these flag in the event. However, on onResult()
the intiall event parameters is lost. It appears to be a new event
object. Therefore, the responder onFault(event) and onResult(event)
have no notion of any flags that were set before the service call.
Is there a solution that you might know of to address this? The basic
gist of my problem is to retrieve any event attr in onResult() and
onFault() that were sent on the event when it was intially broadcasted.
TIA,
George

[flexcoders] Re: Need help in tackling this event problem...
Actually that is the problem. The event I dispatch *doesn't* appear
to be the same event I get back in my result handler.
We use our custom event broadcaster to pass an event, pass it some
event data, and pass the Responder object (ViewHelper) in our case.
The command has access to the event data and does it's execute() thing
(it makes a service call). However in our Responder.onResult(event)
and Responder.onFault(event), the event doesn't appear to be the same
event I passed in. For instance, event.data and event.type yields
undefined.
According to the Cairngorm documentation the returned event after a
service call :
event - An object containing the data passed back from the service
call...
Kinda leads me to believe that the event object avail in onResult()
and onFault() is not the same as the one that was broadcasted prior to
any backend service call.
Maybe this is Cairgorm that's not working as I want it to? Any
Cairgorm guru's out there?

[flexcoders] Re: Need help in tackling this event problem...
JesterXL,
Yeah, that's kinda what I suspected. I suppose I could stick it in a
ModelLocator. However all my events are asynchronous, so I suppose
that *theoretically* your data in ModelLocator might not be in the
*correct* context if, say, you have some chained asychronous events right?
thanks,
George
--- In flexcoders@yahoogroups.com, JesterXL [EMAIL PROTECTED] wrote:
Oh... well that's different. The reason you're not getting it is
because
the event you dispatch is handling internally in Cairngorm, and
triggers the
Command. After that, it's done, gone, and no longer can be access.
The
Responder.onResult event is the event returned from a successful
webservice
call, and is a totallly different event object.
You could instead stick the data temporarely on the ModelLocator so
whoever
is utilizing the Responder's result event can look there for context.

[flexcoders] how do you guys handle browser back button cases?
Say I logout in my Flex RIA. I then hit the browser back button. I got back to the last page. If I make another remoteObject invocation at this point, my code catches the invalidated session and it is dealt with accordingly. But I wanna catch the session invalidation status when I hit the back button. Is there a way to do this? Does hitting the browser back button fire off a Flex event I can catch? I would like to redirect to the login page when someone hits the back (or forward) buttons when the session has already been invalidated. thank you, George Yahoo! Groups Sponsor ~-- Get Bzzzy!

[flexcoders] datagrid column sorting
Hi, When you sort columns in a datagrid, I assume that data in a column is sorted according to its natural sorting order (whatever that may be). In my case it's a string. For some reason, the sorting on this column behaves differently. I have data that begins with uppercase and lowercase letters, and columns that are just blank. When I sort on this column I get uppercase, blank, and lowercase (and vice versa when sorting in the reverse order). I'm expecting the sort to be uppercase, lowercase, and blank (and vice versa). Is anyone aware of such a behavior? It's hard for me to pinpoint because I don't have this behavior on my local build, but it's there in a staging build. Thanks, George Yahoo!
