[flexcoders] Re: Flex validator in action script

[valdhor]

Untested but how about...

[Bindable] private var textInput:TextInput = new TextInput();
private var val:Validator = new Validator();

textInput.id = "myText"; //Don't know why you need this as you can refer
to the TextInput by its variable name (textInput)
val.source = textInput.text;
val.required = true;

[flexcoders] Re: Switching Item Renderers

That seems overly complicated to me. What I would try is create two custom 
components then instantiate the appropriate one based on the data and add it in 
the updateDisplayList method.

The creationComplete handler will only fire once upon initial creation. I would

[flexcoders] Re: Calculating width of a child BEFORE it's added...

I wasn't clear before -- I don't know the width of the VBox beforehand.  I was

make it.

But the measureText() method worked perfectly for me, thanks.

[flexcoders] AIR and Printing...

[Laurence]

I could really use some major advice here.  We're so close to the finishing 
point on this project, and we're being held back by stupid printing problems...

We have to be able to print with no pop-up dialog boxes, and the choice of 
which printer to send the job to will be affected by the data (i.e. a client 
with reg-code X gets printed on printer-1 and a client with reg-code Y gets 
printed on printer-2.)

We have to automate this, because the temp-workers we hire can't be counted on 
to remember how do it correctly.

So...  Any ideas on how I can deal with this?  Should I dump Flash Player and 
switch to AIR?  Would that give me better control over the printing?  Can AIR 
actually do all that I'm asking for here?  What will switching to AIR mean for 
accessing our data from our ColdFusion/SQL server through https:, if anything?

[flexcoders] Flash Builder unable to debug (missing flash player)

[Oleg Sivokon]

When I hit F11 I'm getting this message: "File not found: flashplayer". No
more explanations given. Any ideas of what went wrong? (I'm on Linux, and of
course I have flash player...)

Re: [flexcoders] AIR and Printing...

[Alex Harui]

AIR does give more control over printing.   AIR requires installation, a 
web-hosted app does not.  I don’t know the security rules that well, but it 
isn’t clear how you prevent someone from installing the app and accessing your 
server unless you require authentication first.

[flexcoders] Flex chart DataTimeAxis Interpolation/Extrapolation

[fayaz140284]

I have a question regarding the implementation of a Time Series chart in Flex. 
These charts are used for reporting purposes.

Does flex charting do any of interpolation, extrapolation or smoothening of 
plotted series based on the data?
Or the data provided for chart should take care of this. 

So far what I have observed in Flex is that all points provided are considered 
for plotting and we could no way control the Line Series.

 
We have data collected with interval in minutes 
So if we plot a graph for a day then the x-axis should show data on a per hour 
basis. If the data contains all the points for a week then the above graph 
should be re-calibrated to days in x-axis

Does Flex charting provide this kind of facility? If so how? 

Any pointers are much appreciated.

[flexcoders] Re: memory leaks and activation-objects

[lew.miller]

Yes.  That's precisely what I'm doing.  Only, looking at the code now I realize 
most of the time I'm using nested functions (with names) rather than anonymous 
functions.  I'm not sure what the implications are of using one over another 
are but, regardless, I gather you're suggesting this is a potential problem?  

A typical example of what I'm doing would be something like:

private function showDialog(x,y,z):void
{
  var dialog:SomeDialog = new SomeDialog();
  dialog.addEventListener("ok", function doSomething(e:DialogEvent):void 
{
  someMethod(x,y,z);
}
  dialog.show();
}

I'm using the nested function because I need some way to get the x,y,z values 
into someMethod.  Does this code look problematic?

Thanks much for your help!

Lew

[flexcoders] Re: AIR and Printing...

[Laurence]

The installation/authorization stuff I can deal with...  Not being able to 
control my print jobs properly, I can't deal with.

I can find surprisingly little information about printing in AIR -- it's almost 
like printing was an afterthought for Flex and AIR.

Exactly how much more control over printing does AIR give me?  Can it print 
everything without pop-ups?  Can it control which printer the app sends the 
print-job to -- again, without pop-ups?  Those are the two main things I need.

Thanks,
L.

Re: [flexcoders] Re: memory leaks and activation-objects

[Alex Harui]

I don’t like anonymous functions, nested functions or whatever you want to call 
function instances.  Everything on the callstack is referenced by the 
scope-chain/activation object until the function instance can be GC’d.  Once 
you call removeEventLIstener, then the scope-chain goes away, but until then, 
lots of things are kept around.

It is generallyl more efficient to make doSomething a member method on the 
class.  Or create a helper class that handles the dialog and stores the x,y,z 
values.

When you originally posted I thought you were saying that an activation object 
that should go away wasn’t or was blocking other things from going away.  
AFAIK, that isn’t true, but activation objects are kept around by references to 
function instances and can lead to unexpected memory usage.

Yes.  That's precisely what I'm doing.  Only, looking at the code now I realize 
most of the time I'm using nested functions (with names) rather than anonymous 
functions.  I'm not sure what the implications are of using one over another 
are but, regardless, I gather you're suggesting this is a potential problem?

A typical example of what I'm doing would be something like:

private function showDialog(x,y,z):void
{
 var dialog:SomeDialog = new SomeDialog();
 dialog.addEventListener("ok", function doSomething(e:DialogEvent):void
 {
 someMethod(x,y,z);
 }
 dialog.show();
}

I'm using the nested function because I need some way to get the x,y,z values 
into someMethod.  Does this code look problematic?

Thanks much for your help!

Re: [flexcoders] Re: AIR and Printing...

[Alex Harui]

I use this version of the doc: 
http://help.adobe.com/en_US/FlashPlatform//reference/actionscript/3/flash/printing/PrintJob.html

There are lots of new printing features in AIR2.0 which may be why there isn’t 
a lot of searchable info.  The link I supplied implies that in AIR 2.0, you set 
the PrintJob.printer property to a printer and call PrintJob.start2() to skip 
the dialogs.  Not sure how it will work on all platforms so give it a try.

Plan B, I think, is to generate a bitmap of the page and upload it to a server 
than can access the printer.  Can work for shared printers but not local ones.

[flexcoders] Re: AIR and Printing...

[Laurence]

It does seem, from reading that document, that you can choose the printer to 
send the print-job to, and set the parameters for that printer, and skip all 
the dialog boxes...  I'll have to play with that...  Thanks!

My next question, then, is accessing remote data -- my Flex app using the Flash 
Player has no problem calling a remote ColdFusion function to grab data from 
the SQL server, and send data back there...  How much does that change in AIR?  
Or is it pretty much the same thing?

Re: [flexcoders] Re: AIR and Printing...

[Alex Harui]

I don’t know if there are any differences.  I did a quick search and didn’t see 
any links to articles complaining about it or explaining how to do it so I’m 
going to guess that it works as expected.  There are Security WhitePapers on 
the Adobe site if you want to read more about AIR security.

[ZIONIST]

am not sure i understand your question... all i did is develop the two apps 
separately and deployed the release build version of the site to the wwwroot 
folder on the host server and the release build version of the admin site to 
the admin folder in the wwwroot folder.

Re: [flexcoders] Re: separate flex apps in same webroot folder

[Pr@vin Uttarwar]

As I have seen your swf it is not loading completely and its size is less
than 200 kb,
so it must be loading framework as RSL.
Also it might load if you out it in same folder ,if it is so,then problem is
that the framework setting is wrong,

try putting framework_.xx in admin folder and try again.

[ZIONIST]

i already have framework_.xx in the admin folder.

Re: [flexcoders] Re: separate flex apps in same webroot folder

[Pr@vin Uttarwar]

ok
As i have seen your main site i saw firebug that it is loading framework swf
of 500+ kb.

So i thought it is might not loading the same for admin.
Also is it working if putted in main folder?
