[flexcoders] FB3/Eclipse - CSS design view not showing images

[John Robinson]

Anyone encounter this? I'm using Eclipse with the Flex Builder 3  
plugin. I'm trying to skin a horizontal scrollbar with some images. I  
just discovered the CSS design view/editor and  thought it was exactly  
what I need. The problem is that I choose my images and hit refresh,  
but they don't show up. It displays the little blue icon all stretched  
out (like a missing image icon).

Anyone?

Thanks!
John

Re: [flexcoders] Polling vs. Timeout error vs. ???

[John Robinson]

if you only have to reload the data every 3 minutes, you should be  
fine using a timer.

You won't get the 'script running too long' error as a result of using  
a timer. That error happens basically when  code takes too long to  
process or goes into an infinite loop.

Thanks Josh! I haven't tried to implement this yet but so far it makes  
sense.


Thanks again,

Yeah, I've been directly updating the properties. Here's the weird  
part... if I use the ArrayCollection as a dataProvider for a List  
control, it updates. If I use it for a custom control that I've  
created, it does not.



Example:

This works as expected:


This does not:


//pseudo component source


private var _dp:ArrayCollection;

public function set dataProvider(dp:ArrayCollection):void {
_dp = dp;
	trace("this fires when the AC is created, but not when it's  
contents change");

Nice catch! That didn't seem to be causing the problem but thanks for  
pointing it out.

I've simplified the case in that I'm not calling the web service  
anymore, just flipping the enabled property but binding still is not  
updating. Any other ideas?

[flexcoders] binding not updating for ArrayCollection when item changes?

[John Robinson]

I have a strange issue with data binding not updating when an item in  
an ArrayCollection is changed. I'm using Cairngorm and have the  
following setup. In my ModelLocator I have a 'users' ArrayCollection  
that contains 'UserVO' objects. I have a two views that binds their  
dataProvider to the 'users' AC in the ModelLocator. My UserVO looks  
like so:

package com.jrobinson.model.VO
{
[Bindable]
public class UserVO
{
public var id:int = -1;
public var username:String = null;
public var enabled:Boolean = false;
public var userData:XMLList = null;


public function UserVO(user_id:int, uName:String, 
enabled:Boolean,  
d:XMLList)
{
id = user_id;
username = uName;
enabled = enabled;
userData = d;
}

}
}

I first have a command that loads all of the users and populates the  
AC. This updates the bindings as expected. I then have a second  
command that loads the userData portion for a given user. Once  
retrieved, I update the given UserVO's userData, but this time, the  
bindings fail to update.

I feel like I've seen this before but can't find where or what the  
workaround might be. I guess I'm just looking for confirmation that  
this should or shouldn't work.

Thanks!
John

As far as I know they haven't. They're AS2 map stuff has a version

You're using static methods of the PopUpManager class, so I don't  
think it ever actually instantiates PopUpManager. If you want to  
access PopUpManager from elsewhere, just import it and use it. If you  
want to get to the popup that's created, that's a different story.  
I'm not sure why you'd want to do that, but I think PopUpManager  
keeps a list of it's popup's somewhere, that you might be able to get  
at. (Again, import PopUpManager and access it's properties/methods).

[flexcoders] Flex 3 apache module on OSX?

[John Robinson]

Anyone successfully get this working? I ran into some hurdles during  
the install and am not quite sure I've got everything setup correctly.

The hurdle was that the installer wanted the path to the apache  
config directory, which when using the built-in webserver is hidden  
in "/etc/httpd". My solution was to copy this directory to a visible  
directory on my desktop and point the installer there.

Then it asked for the webserver root directory which it picked out on  
it's own "/Library/WebServer/Documents". This is where it put the  
"samples" directory.

After the install, I copied the files from my mock httpd directory  
into the real directory and restarted the server. Nothing. I then  
went into "/Applications" and noticed that instead of creating it's  
own folder, it just dumped it's files all over the applications  
directory. I then put these into their own folder  called  
"Flex3Apache" and updated "compiler.conf" and "httpd.conf" to reflect  
that. Restarted the server again but still no luck. When I browse to  
an mxml file, it just shows me a blank page (very snappily I might  
add, like it's not hitting the compiler at all).

Anyone?

Re: [flexcoders] Re: Is there any way around the crossdomain.xml

I honestly have no idea. What is the webservice you're trying to use?  
It looks like it requires some sort of authentication and ssl?

Can you find any examples of consuming the service with php? If it  
isn't something you can work out in flex perhaps you can make php do  
all of the work.

Re: [flexcoders] sandbox error

[John Robinson]

I'm not quite sure what it is you're doing, but it sounds like you're  
talking directly to mysql over a socket connection. I'd be very  
careful in doing so in that all of your mysql authentication info is  
included in the swf file. The swf can be easily decompiled and your  
database compromised.


I'd look into using server-side technology to handle the mysql  
interaction CF/PHP/etc.


Aside from that, you're swf once uploaded is running in whatever  
domain you uploaded it to. If you want to disregard the above, and  
just get it working, make sure mysql and the swf are running on the  
EXACT same domain.

Hello all,

I am using flash.net.Socket class to connect mysql database. And I

regarding this problem.


1) When I develop the flex application and mysql database

violation box error, since they are considered as in the same  
domain. Am I correct?
2) After I upload the flex application the server which is equipped  
with mysql, I access the flex application from client machine.  
Firstly the flex application will be downloaded to the client  
machine's cache, then start to execute. Now flex application and  
mysql database are considered as in different domain, and the  
sandbox violation may happen?
3) In order to solve it, I need to enable mysql remote access? Set  
mysql server address to digital format (xxx.xxx.xxx.xxx) to instead  
of "localhost"?

4) Or alternative way to solve it is to set "crossdomain.xml" file?
Thank you.

Joe

Re: [flexcoders] Is there any way around the crossdomain.xml

[John Robinson]

First, ask the folks who provide the webservice to install a  
crossdomain.xml file for you. If that isn't an option, you can make a  
php/etc proxy file to do the loading for you. Google "php flash proxy".

Re: [flexcoders] Parse Unknown XML Structure

[John Robinson]

I think you want to use XML.children() and XML.attributes().

Hey all,



First post, so be gentle.



Back in the ol days, Flash developers had to use recursion to parse  
through an XML document. I’m finding myself again in this position,  
but don’t know how to proceed as my initial attempts don’t recurse  
currently. Also, I’d like to find out if there is a better way to  
do it with AS3 these days.




Basically I need to be able to look at every node and tell:

-  whether or not it has specific attributes

-  whether or not it has children



I know this seems easy, but the XML structure isn’t known  
beforehand, so using simple object notation seems futile.




Thanks for any help you can provide…

Re: [flexcoders] New Apollo screencast: SearchCoders/Dashboard now has chat

Very cool. Though I'd change the name from "Dashboard" to something

Other than that... woot!

Re: [flexcoders] Instantiating uncompiled MXML at runtime in flex

[John Robinson]

Do you have an example of the xml?

Does it have actionscript in it, or is it just laid out components?  
Laying out components is easy... figuring out and running AS is quite  
a bit more difficult.

I've done some experiments with loading pseudo-mxml at runtime and  
displaying it, but there are some caveats.

First, you need to make sure any components you *MIGHT* use are  
compiled in the swf. I ended up having to do something like so in  
order for that to happen:

import mx.controls.Panel;

private var myNonExistingPanel:Panel;

Then you have to worry about setting properties and styles on the  
component, based on (usually) the attributes in the xml. Not using  
attributes but nested tags makes things a little bit more difficult.

Hope that helps a bit.

John

Flash Player Security Forum (was Re: [flexcoders] Re: Load & Display Image from FileReference)

[John Robinson]

Initially I had a whole post asking questions about why this was the  
case (can't reference user-selected file without uploading/ 
downloading first) but I felt it was pretty OT for the flexcoders  
list (or probably flashcoders list for that matter). Does anyone know  
of a venue for discussing Flash Player security specifics?


Thanks,
John

I have no specific knowlage but my guess is that flex doesn't  
actually access your file system.  What it probably does is tell  
your browser to access the file system.  In any event, this issues  
has been widely discussed and there isn't a way around it (unless  
you can figure out how to hack adobe's security sandbox).

Re: [flexcoders] output formats (excel/word)

[John Robinson]

Flex doesn't have any output formats or any of this functionality  
built in. I'd say build your front end in Flex, but continue to use  
CF for your file output. Simply send your data to a CFC that does the  
conversion and then allow the user to download (or whatever) the  
outputted file.

Re: [flexcoders] Re: Html Text does NOT print in same format as rendered on scre

[John Robinson]

Scott -

I didn't notice the loss of quality when I tested it (quickly)  
yesterday, but I'm noticing it now that you mentioned it.


I played with it a bit more but the only thing I found that helped at  
all (though still not great) was to set "smoothing = true" for the  
Bitmap. It looks better but is now a little fuzzy and on paper (cheap  
inkjet) the text is not as dark as the one without smoothing. I'm  
wondering if it's possible to overlay the no-smoothing bitmap with a  
transparent background over the smoothed version?

Thanks for the example John! However, when you printed your output

i lose a lot of quality on the printout, font is real jagged.

The bitmap image created from my source panel is very clear on. I
assume this is because the flash player is not printing it
intellegently as a font but rather an image.

Even so though... the bitmap image is pretty darn close to the real
dimensions of the printed page, based on 72pixel per inch.. Would
think i would lose that much qualtily.

[flexcoders] modules with video

[John Robinson]

I have an app that has a few external modules that it switches my  
"main" view between.

One of these modules has an externally loaded video (using  
VideoDisplay, or whatever it's called).

When I load this module up everything works fine, the video plays, etc.

When I unload it and load a different module in it's place, the  
module with the video is removed from the screen but I can still hear  
the sound playing. Anyone?

Also, I'm somewhat confused by how modules really work. All of the  
examples I've found via google seem to reference a time before the  
official inclusion of the module related classes (pre-2.0.1 update?).

Does anyone know of a good reference point that'll help me get my  
head around what the Flex framework is doing when I load/unload modules?


Thanks!
John

Re: [flexcoders] Re: Html Text does NOT print in same format as rendered on scre

Scott -

I thought the same thing (use Bitmap/BitmapData). Quick example:



http://www.adobe.com/2006/mxml";  
creationComplete="init()" >






	autoLayout="true" click="onClick()">



	height="{my_panel.height}"/>




I didn't try going to a printer but just saved as a pdf. Page 2 looks  
just like it's displayed in the browser, while page 1 looks like the  
text has been shrunken horizontally a tad. Strange, but using bitmap  
should solve your issues for now.


Note... I tried adding the Bitmap object and the BitmapData object to  
the printJob but it gave me errors so I'm not sure if the image is  
necessary or not.

I ran into something like this the other day. "getDefinitionByName()" 
is what you're looking for.


// import utils
import flash.utils.*;

// our target class
import mx.controls.Button;


var className = "Button";

var theClass:Object = flash.utils.getDefinitionByName("mx.controls." + 
className);

var theNewObject = new theClass();



I only messed with it long enough to get what I needed out of it so 
others here might be able to chime in. As far as I was able to tell, 
you still need the full path ("mx.controls." in this example).
