Usually when I run my application Flex Builder creates a file in a directory on my local PC and then opens a browser and points to it. Everything was fine, but when I decided to link django server to flex applications via xml data providers I started to get security errors. (Related to absence of crossdomain.xml). When I created the file and put it on the server[code]...

I'm building from scratch a web application that is not trivial (have some algorithms and calculations in the backend) but not too complex (it doesn't have to process lots of records during runtime. We thought about using Django for the backend in order to be able to develop the application fast with flex based GUI.
I'm a Java developer with no experience with Django so basically I wanted to know if using Flex and Django together is a good option in terms of ease of development and maintenance? I saw that there are several libraries such as pyAMF and DjangoAMF for this purpose, but since Django is also about html templates and MVC, does flex really work well with django?
(This is the first time I've done this actually.)
<mx:HTTPService id="post_update" method="POST" result="{Dumper.info('bye')}"/>
The result handler above is just for debugging purposes, but its never hit, even though what I'm uploading via POST..

I am creating a django-based site that will serve flash apps that occasionally access data via pyamf. I need to be able to easily test the flash in the context of the django framework, i.e. with all the login cookies and everything available, so that when I make a pyamf call, it has all the user context there. And I need to be able to test and release both the swf's and the wrapper html's in a sane way. However:
The html templates in flex are already templates, so if I put template code in there for django, it gets scraped out before the flashapp.html is created. The html's and swf's automatically get released to the same directory, but I want them to go to different directories because the swf's shouldn't be served by django and the html's should be in an area in control of django.

I have some audio data in a byte array in a Flex app that I would like to save to my model in Django. I assume I would use a FileField, but I can't seem to get it to work. (My project is set up like this.) I've tried looking at this sample code for PyAmf, but I can't quite get the two to combine.
View 1 RepliesIn my Flex app I am using a repeater to show a report on my database data. On this report the user can "drill-down" on the data to show more detail. In order to make this easier on the eye I have a header label and then a datagrid within the repeater.Whilst this works perfectly, because the dataprovider for the datagrid comes from an array in the repeaters dataprovider, it is causing the following warning:Data binding will not be able to detect assignments to "report"The warning is for this line:
<mx:DataGrid id="dgReport" dataProvider="{rptReport.currentItem.report}" rowCount="{rptReport.currentItem.report.length}">

The problem with flex applications is that a user can download it and run it on his local machine or possibly host it on another site. Is it possible to lock a flex application to a domain name to prevent such acts?

I was running my application from Flash Builder 4.5.1 without any issues. (It is a Flex application that connects to .Net Web Services). However, something has changed recently in my configuration or project, because when I try to run the app with the play or debug button, I just get a grey screen. I can't even stop on any breakpoints. Eventually (maybe 30 seconds), a message pops up like so: 'The Flash Builer failed to connect to the running application. Please make sure that you are running the debug version of Flash Player...'

View 2 RepliesI have a quite different problem with resizing. I have a Flexbook component which uses the middle part of screen (center) with a html header menu and footer. The problem: The scaling works perfectly when we run in the local machine ( Flexbuilder). But when we deploy it to the server its like scaling never existed.. The requirement: when user maximizes the window or minimizes it, the Flexbook should be resized to fit the screen.

I have an air application that loads a swf ( built in flex ) , this swf loads moduls and basicaly my air application is a testing environment for this swf .
when i run it in flex environment ( eclipse ) it runs fine , when i run it from my programs ( as an air program ) it gets stuck , what i was thinking is that it has to do with security issues because it gets stuck when my main swf try to loads the moduls .
I recently got flex builder 3, and it seems to be a really cool IDE.
View 4 RepliesI'm a GIS Analyst that was moved to an Analyst Programmer position. This has been a hard transition for me as I don't have much of a programming background, but I was thrown into it. 'm working on a Flex app inside a jsp page. Essentially it is a grid 3x2 that has images and text. What I am trying to do is have more than one titleWindow reference in this page, so that when an image is clicked a titleWindow is opened. (If anyone has a better idea, especially if it has to do with a hover I am very open to that!) Currently I have it working for one image. However, when I try to add a second function it errors on me. "Error 1021: Duplicate function definition" Below is the entire code for the main page that calls up the titleWindow. The code below is what gives the Error 1021.

How to develop and compile a Flex application without Flex Builder?
View 2 RepliesI've built a simple application in Flex Builder 3 with some trace() calls. It's an "ActionScript Project", no MXML or AIR involved. I don't run the app from within Eclipse, I just open the generated html file with Firefox.
I'm using the Flash Player 10 Debug version. I've correctly set mm.cnf to log trace output, following the official instructions. A flashlog.txt file is generate in the appropriate location.
Despite all that, trace output is not shown in the log file. What am I doing wrong?
(I suspect it's a compiler option, but I can find no such option in the project options in FlexBuilder)
(If I do run the app from Eclipse, by pressing F11, I can see trace output but only inside Eclipse, not in the log file)
In my Flex 4.6 web application I use mainly spark components, but there is also an mx-component - a PopUpButton extended by me (the source code is below).Users report problems with that button, but I can't reproduce any - since weeks.
I've tried replacing mx:Menu attached to it by a s:List but it hasn't changed anything. I suspect there is a "null pointer exception" or some other failure, that I don't hit when testing myself...
My question is: why does Flash Builder reports warning about my custom button as if its methods would be private or not present?
My main App.mxml:
<?xml version="1.0" encoding="utf-8"?>
<s:Application

When creating an Actionscript Project in Flex builder 3 an application class is automatically created and dropped in the root of your source folder. In my case my source folder is called src/.Is it possible to change the default application class to a class which is not directly in the root of the src folder? It seems when right-clicking on class files which are in sub packages the 'Set as Default Application' option is not selectable.Is this done on purpose by Adobe to enforce all pure AS projects to have their application class residing in the top-most package?

View 1 RepliesI'm new to developing iOS applications and my school gave me approximately 5 months to develop an iPad application. I have no knowledge or practice on Objective C so since Flash Builder 4.5 allows the development of mobile applications (and I have experiences with Flash Builder), I decided to develop my application on Flash Builder instead.
Everything is going fine until I was told to include a SplitView in my application. I implemented a List on the left side of the application. Clicking on any of the list items will navigate the user to a to another view but i also included and retained the list on the left side of the new view in order to simulate a "SplitView".
Initially it felt as though it will do the job of a SplitView like how it does when I attempted it on XCODE but it doesn't look or feel natural. I found this video which shows that it is possible to create a SplitView on FB but I've cracked my brains and I really can't figure out how it is done.

View 1 RepliesI am trying to create a simple board game (a kind of checkers), where users will be able to play online with each other using flex application as a client.
I am using django application to process the game on the server side. And I come across the problem, if one user made a move, I can send it to a server, but how do I let the opponent know about it?
The way I am thinking to do it is to create a timer and send requests to the server asking was opponents move done or not....But here we have 2 limitations:
1) Each client would produce big amount of requests (not sure how server will work if I have e.g 100 such clients)
2) If players will chose game with a time limit for example 5 minutes/per game it will be very important to show them situation on the board as soon as it changes (without a pause), but timer will send request only on timer event, so if for example I will chose tick interval to 5 seconds it will mean that 5 seconds another side will not be aware of the situation changes.
For example, using my UserProfile model:
class UserProfile(models.Model):
user = models.ForeignKey( User, unique=True )
blurb = models.CharField( max_length=200, null=True, blank=True )
[code].....
I'm able to return django models that have only CharFields/Dates/Integers, but now I'm trying to return models that have ForeignKey properties and I'm getting this error in Flex in my NetStatusEvent.NET_STATUS onError event handler:
m_info Object (@16491fe9)
code "NetConnection.Call.Failed"
description "HTTP: Status 500"
details "[URL]"
level "error"
Here are the models that matter in models.py:
class RewardActBase(models.Model):
user = models.ForeignKey(User)
start_date = models.DateTimeField(blank=True, null=True)
progress_value = models.IntegerField(default=0)
[Code] .....
Then when I want to get retrieve these object via pyamf, this is the method I'm using, which is giving me the error I listed above.:
@login_required
def get_challenge_act(http_request, location_id):
user = http_request.user
c = ChallengeAct();
[Code] .....
The interesting thing is that if I change my get_challenge_act method to return a property of the ChallengeAct object, I don't get the error. So I can return properties or objects that belong to the ChallengeAct, but not the ChallengeAct itself. For example, the following code returns a Challenge object with no errors:
return c.challenge
So it appears that there is some problem returning a Django model with foreginkey models as properties?
