[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. Thanks in advance, Barry
[flexcoders] Re: Capturing URL Requests in AIR application (HTML/HTMLLoader/HTMLHost)
Yes your kind of right, what i think i really need to do is extend the HTMLLoader class so that i can override the load(urlRequestToLoad:URLRequest) method. I have tried this and get similar results to the user from this post (http://tech.groups.yahoo.com/group/apollocoders/message/2900), the new extended HTMLLoader is not visible on the stage.

[flexcoders] Re: Dual DataService components causing problems
Ok i managed to get the problem sorted. All i had to do was create a dummy instance of the mx.data.messages.SequencedMessage class in the main application. Previously, I had to do this will alot of my own AS classes (and a few from the Flex framework), but now i am using an RSL (where most of the classes exist) it was not necessary to create any of the dummy instances of the classes... or so i thought! Well that seems to be the problem solved, thanks for your pointers Seth/Gregor.

[flexcoders] Re: ModuleLoader erratically loading modules
Can i ask if you are loading the same module into each 'stub'?
i.e. do you have a multi-purpose module that is loaded 4 times
(SubmissionModule.swf)?
I had a problem with loading a single multi-purpose module more than
once. I was dynamically loading n modules that contained a number of
hyperlinks.
The problem was that the 2nd module was being loaded before the 1st
one was ready, resulting in the 1st module being garbage collected,
and therefore never loading.
Let me know if this helps.

I'm having a lot of issues with ModuleLoader only occasionally
loading
my modules. At first I thought maybe it was that I couldn't have
the
module open in more than one tab at a time in my browser, as this
seemed to help a little. But it seems more like there is a basic
problem with loading multiple modules at once.
Basically in my main mxml I have:
mx:Canvas id=views_canvas x=10
views:PrizesStub id=prizes visible=false /
views:Home id=home visible=false/
views:ListStub id=list visible=false /
views:SubmissionStub id=submission
visible=false /
/mx:Canvas
where the stubs are stub components for the modules, so they can
hold
data that might be needed before the module is loaded.
One of my stubs looks like:
?xml version=1.0 encoding=utf-8?
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml;
mx:ModuleLoader id=module
url=views/SubmissionModule.swf /
/mx:Canvas
That's pretty much it. The SubmissionModule will only load once
every
4 or 5 times I debug. I've tried adding unique identifiers to the
url
like:
mx:ModuleLoader id=module
url={'views/SubmissionModule.swf?uid='
+ new Date().getTime()} /
but that doesn't seem to help.
The ready event never fires when it doesn't work.
The only thing I can think of is that it is loading all of the
Modules
at once(once the main swf has loaded) even though the views that
contain them aren;t visible. Is there some reason that shouldn't
happen or would cause a problems?
[flexcoders] Adding a non-inline creationComplete event handler
Hi, i am having serious memory leak problems whilst using modules in flex. The module-based application i am currently developing currently over time kills the browser its loaded in. Even when i attempt to load the simplest of modules (a module with a few buttons/empty datagrids) my flex app will eventually make IE/Firefox fall over after consuming about 650-700MB of RAM. I have been reading Grant Skinner's posts on memory management and weak reference techniques with regards to Flex/Flash player but i am still having big problems. I am also attempting to figure out how to add a creationComplete event handler on a module via actionscript. If i use the inline mxml approach, a strong reference will be created, and i will never be able to destroy it, resulting in the module never being removed from memory! Any advice and/or comments would be most appreciated, as i am hitting brick walls here and i need to progress with haste. Thanks, Barry

I use the problematic module on more than one occassion i.e. when

Subject: [flexcoders] FDS Messaging error
Hi all,
I'm trying out a sample chat app using fds messaging. As
per the instructions, I made a new destination in the
messaging-config.xml as
follows:
destination id=MyTransientTopic
properties
server
durablefalse/durable
/server
/properties
channels
channel ref=my-rtmp/
/channels
/destination
Unfortunately, my application does not seem to get this
destination is throwing the following error:
[Error: (mx.messaging.messages::ErrorMessage)#0
body = (null)
clientId = (null)
correlationId = AC6C8425-5819-7952-C465-DBB44D54B08E
destination = MyTransientTopic
extendedData = (null)
faultCode = Server.Processing
faultDetail = (null)
faultString = No destination 'MyTransientTopic' exists in
service flex.messaging.services.MessageService
headers = (Object)#1
messageId = 996330F1-2418-1987-0B1E-A4C224645BD9
rootCause = (null)
timestamp = 1176212098404
timeToLive = 0]
Where am I going wrong? Please help !

[flexcoders] Re: FDS Messaging error
robi, i just figured out that when you create the new project in flex builder 2.0, you need to make sure you choose the option 'Flex Data Services' when asked 'How will your Flex application access data?' in the 'Create a Flex Project' dialog.

[flexcoders] Re: FDS Messaging error
No it doesnt work in firefox either.
I guess there is some sort of configuration in the Project that
defines where the data comes from.
I found out that if you choose the option 'Flex Data
Services' when asked 'How will your Flex application access data?' in
the 'Create a Flex Project' dialog, the sample chat client is able to
talk to the messaging service 100%

Does it work in Firefox and just not in IE?
If so, we had a problem on IE making remote object calls to our
server when using https.
Adding the following:
mx:Script
![CDATA[
import mx.messaging.ChannelSet;
public var channelIDArray:Array = new Array(my-
amf, my-http, my-secure-amf,my-secure-http);
[Bindable]
public var servicesChannelSet:ChannelSet = new
ChannelSet(channelIDArray,false);
]]
/mx:Script
and setting:
channelSet={this.servicesChannelSet}
in the MX:RemoteObject tag fixed the problem.
otherwise post you configs and how you are compiling. Provided your
config is right the easiest way to get the client compiled correctly
is to have it compiled on the server where it will be served from.
