RE: [SPAM] [flexcoders] What server do I put my crossdomain.xml file on?

[Tracy Spratt]

I am fairly certain that it will need to go on the server that is hosting
the servlet, since that is the only domain that the FlashPlayer is going to
know about.  That would be: http://da803299:8080  .
I am not sure how the sandbox handles port specifications in the url,
though.

 

When in doubt, put a completely open crossdomain everywhere until it works,
them remove them until it breaks.  Then close up the domain and port specs
as needed.

on?

 

  

Hi - 

I have a Flex app that uses an HTTPService to call a Servlet. The servlet
retrieves a file on another domain and passes back to Flex where they are
prompted by a Windows dialog to either save or open it: It works fine
locally. 

When deployed, I get this error:

Error #2044: Unhandled SecurityErrorEvent:. text=Error #2048: Security
sandbox violation: http://bopswdmmk1:

15010/oats/FlexClient/OATSMain.swf cannot load data from http://da803299:

8080/oats/FTPFile?filename=/oats/oatsftp/feed/Session.csv.01062010.

I'm assuming this is because I need a crossdomain.xml file, right? If so,
where do I put it? On the domain that hosts the servlet, or the domain the
file is retrieved from? 

Crossdomain issues can be confusing and any insight would be greatly
appreciated. 

Thanks,

Matt

RE: [flexcoders] Flex4: getChildById or getElementById

[Gordon Smith]

You can write code like

if ("mycomponent" in this)
{
this["mycomponent"].doSomething()
}

to avoid an FTE with mycomponent does not exist.

RE: [flexcoders] flex 4 text styling

[Gordon Smith]

Flash Player 10 introduced a new text system known as FTE (the 
flash.text.engine classes). It also continues to have the old TextField class. 
So there are basically two text systems, with their own ways of doing text 
formatting.

They have some formats in common, but each also has formats of its own. The 
fontSharpness and fontAntiAliasType formats are not part of FTE and therefore 
not supported by Spark components, which use FTE. Their closest relatives in 
FTE are renderingMode and cffHinting.

If the dataTipFunction doesn't give you enough flexibility, you could try a 
dataTipRenderer.  In either case, you can drill down to the child nodes there.

[flexcoders] Re: Flex Video and Firefox Issue

[arocheking]

In case someone else has this same problem. 
Here is the solution.

set apache to turn off gzip compression 
in httpd.config (or could do it in .htaccess) we added m4v to the following 
line.

# Don't compress images
SetEnvIfNoCase Request_URI \
\.(?:gif|jpe?g|png|m4v)$ no-gzip dont-vary

OR more broadly you could use:

SetEnv no-gzip dont-vary

More info-

From:
http://www.longtailvideo.com/support/forum/Setup-Problems/19359/FLV-won-t-play-in-Firefox

But there is a serious other reason, why flv / f4v files are not played in 
Firefox, but in IE and maybe other browsers.

The reason is Apache itself. Even the latest version (2.2.13) - what we have 
freshly compiled for our Sun Sparc Platforms, has a problem to produce the 
correct header for flv files.

This incorporates that Apache - even if you added the correct mime type for flv 
/ f4v files to mime.types or in httpd.conf as AddType - does not add the 
content-length to the http header.

On IE it works fine, the flash player streams until the web server has the flv 
file served completely.

Not so on Firefox, especially not on some Unix Systems. Your Flash Movie Player 
just keeps on telling you he is buffering the movie, though you can trace from 
the apache transfer log, that the file has benn already transmitted completely. 
But the movie won't start at all.

This unexpected behavior occurs even with having in use the same flash player 
version in IE and Firefox.

[flexcoders] flex-iframe (resize panel container based on html doc height)

[flexfortress]

I have been tasked with a proof of concept for a Flex application, and I've 
been asked to render html within a panel and have the panel resize during 
runtime depending upon the height of the html content.

I've check out the code for Christophe's exmaple - which is a good start:
http://www.deitte.com/IFrameDemo3/IFrameDemo.html

However, I need to have the panel resize on the fly; therefore, making the 
browser implement scrollbars, and not the panel.

I checked out flex-iframe which looks very promising, but I have not been able 
to get the examples to render.
http://code.google.com/p/flex-iframe/

Any help?  Insights?  Has anyone dealt with this?  (I know iframes blow, but 
it's a requirement)  

It seems like I can embed a Javascript function in the html file that announces 
the dimensions to ActionScript and then an AS function resizes the panel - 
which one of the flex-iframe examples proves. but, so far, I haven't been able 
to do this.

Thanks for any assistance!

[flexcoders] What server do I put my crossdomain.xml file on?

[flexcoders] asdoc "Error: Property is write-only."

[Mike]

I'm having an issue with asdoc.  I've tried asdoc.exe from SDK 3.2, 3.3 and 
3.5; the same error always appears:

Error: Property is write-only.
 [exec] Math.pow(10, 2);
 [exec] ^

I've tried putting that statement in other files, and it does not generate an 
error.  If I put that statement anywhere in the class that it belongs to, the 
error appears.  Something about this class triggers the error message.  If it 
put the statement in a subclass of the problem class, no error results.

Suggestions?

[flexcoders] Problem working with webservices and exceptions

[Jorge Silva]

Hi everyone!
I have a problem when working with webservices and backend exceptions.
This is the situation:
I have a backend written  in Java, and a frontend in Flex 3, both connected
through web services. For the TOs (transfer objects) I use the Import Web
Services tool provided by Flex Builder.
Everything works fairly fine... but I have an issue when the backend throws
an exception.
This is the code:

public class SecurityMainService extends MovieClip
> {
>
>
  private var securityService:SecurityWS = new SecurityWS();
>
>
> public function SecurityMainService()
> {
> super();
>
> this.securityService.addSecurityWSFaultEventListener(errorHandler);
> }
>
> public function errorHandler(event:FaultEvent):void{
> Assets.show_alert_alert(event.fault.faultString);
> }
>
> public function deleteRole(aRole:Role, handler:Function):void{
> this.securityService.adddeleteRoleEventListener(handler);
> var arg:DeleteRole = new DeleteRole();
> arg.arg0 = aRole.id;
> this.securityService.deleteRole(arg);
> }
>

 When the backend throws an exception, the errorHandler is called. The
backend sends me a custom exception, and i can see it in the raw http
response, but here, in the FaultEvent object, it seems that is lost... it
suppoused to be inside fault attribute, but it's not.
So, the question is, what I'm doing wrong?
I hope you understand. Let me know if you need more detail to give me a
hand.
Thanks in advance!
Cheers,
Jorge

[flexcoders] styleFunction on adv datagrid

[Nick Middleweek]

Hello,

I've got a groupingCollection as the dataProvider for my adv data grid (ADG)
and I've got a styleFunction attached to the ADG to set the text color to
grey.

The groupingCollection is collapsed to start with and when I expandthe tree
nodes, the rows come into show but they are rendered in the old color during
the time it takes for the grouping node to expand, then it switches to the
grey color.

I can only assume that the styleFunction is being executed after the
grouping is fully expanded.

Is there a way around this because it doesn't behave this way with a flat
dataProvider and it's causing a visible color change which isn't great on
the eye...
