Thanks JC for ur response, PHP is good for server-side and there are frameworks that will help you encapsulate database layer so you can easily switch from one db engine to another e.g. MySQL to PGSQL,etc. May I request u to name good ones so that our study minimizes to few ones for suitability. I Guess these will be Hibernate equivalent, are they ? Built in PHP is PHP Data objects library that can help you with this problem as well if you need a thin layer for your database layer. True we searched the links for PDO Steve has given and going to study them in detail for judging its suitability in our project. if u know some more good alternatives plz go ahead and suggest us since we are starting a fresh we dont have constraints. However we will give enough time to finalize the data access layer since that will be a strategic decision for our all future web applications. So we will evaluate thoroughly every short listed framework and technology for suitability in our most of the existing projects which probably might need to be converted into web application.

[flexcoders] Re: Making ComboBox stay open after item select?
Still not too much to do on that. All the functionality appears to be in
the close function. I've kludged up this to do what you want. There's a
_calling variable in there as the close function gets called twice on
every change (for reasons I don't care to examine) that'll allow it to
dispatch the change event once per frame.
package
{
import flash.events.Event;
import mx.controls.ComboBox;
import mx.events.ListEvent;
public class ComboBoxNoClose extends ComboBox
{
private var _calling:Boolean = false;
public function ComboBoxNoClose()
{
super();
}
public override function close(trigger:Event = null):void
{
if (trigger != null)
super.close();
else if (dropdown != null !_calling)
{
_calling = true;
dispatchEvent(new ListEvent(change));
callLater(function():void { _calling = false} );
}
}
}
}

I need such a ComboBox for a client that opens/closes only if the

clicks on the 'header area' of the ComboBox or that closes only if
clicked
outside the ComboBox.
The use case for this is that the ComboBox will have custom item
renderers
that contain (for example) a CheckBox and a Label and the user
should be
able to make several selections without the ComboBox closing
inbetween.
I've made this before by wrapping all the stuff into a Panel and
changing
the Panels height on close so that only the header is visible but
that
method is rather suboptimal, especially for skinning.
Would be great if somebody has a workaround for this!

[flexcoders] Re: DateFormatter and dynamic resource management errror
Okay, I have what I suppose is a solution to this, but I'm still short a coupla
answers.
1) I ran the resource-bundle-list option again on my application
mxmlc -locale= -resource-bundle-list=myresources.txt
-include-libraries+=..\libs\CairngormWithExtensions.swc app.mxml
which came up with:
CairngormMessages LanguageResource SharedResources collections containers
controls core effects formatters logging messaging rpc skins styles utils
The difference is the SharedResources and formatters, which wasn't in the
original.
2) I recompiled the resource bundles (skipping CairngormMessages, which I'm not
using) over the 15 languages. ie.
mxmlc -locale=da -source-path=locale/{locale}
-include-resource-bundles=LanguageResource,SharedResources,collections,containers,controls,core,effects,logging,messaging,rpc,skins,styles,utils
-output=src/Resources_da.swf
So now it doesn't fall over on MMM or .
However, I have but face. Also, I'm about to make some assumptions... The
copylocale that I used earlier to create the resources seems to do exactly
that: copies. It doesn't actually create a proper locale for all those places.
So January in en_US is still January in it_IT when, according to Babelfish,
it should be Gennaio etc. etc.
What can I do about this?
Where can I get proper versions of these locales?
Is there a way to get the names from the operating system and apply them to
DateBase or is this already happening and I just can't see it because I'm
running an English machine?
Danke for any light you can shed on this.

However, when I try to call a DateFormatter with a full month (MMM or

This is probably referring to the DateBase.monthNamesLong array;
formatting is not an issue with M or MM. Am I perhaps missing something
in the creation of my resource files? This is a sample of the command I
used:
mxmlc -locale=es_ES -source-path=locale/{locale}

What I am trying to achieve is create a line chart with two data series, thus

(google it if you aren't familiar).
When the user mouses over the chart I want to send both data point of data
for both the series to a datatip function. I then want nothing to show up for
the datatip (blank and no gray lines forking out), as I am sending that
hitData info to a function that displays the data series points on another
panel.
So far I have created a custom dataTipRenderer, that is empty, but I still
get the gray lines forking out point to my empty/blank renderer. So it looks
like a gray line sticking out to nothing. Second issue is that I always want
both series to send their data to my datatip function. Sometimes it sends
both if the mouse pointer happens to touch both lines.
I was thinking if I make a custom mouse pointer for just the chart that is a
long vertical line it will always touch both data points, which solves that
problem. Unless anyone has another idea?
The second issue with the gray forking lines I can't seem to get rid of those

Re: [flexcoders] Re: RSS Feeds
I happen to have done a really cool picture browser that took the pics and data from picasa googles website RSS data, when i completely finished it, DANG, stops working on my server cause of security reasons. 1st i agree it should not work on local as well, i threw months of work!!! :O 2nd, i cannot read an RSS cause of security reasons?? wait...RSS were not intended for being used in our apps? those RSS icons there, are not there for us to work with them??? Finally, if i ever have to get data from outside, and i'm considering doing a RSS reader, and other stuff...i will just get the data to flash though a small PHP script. but that security thing really sucks...(T__T) En/na Baz ha escrit: I know this is an old thread but you can't just browse to it - a browser only displays html, but that html comes from a server at some point - i.e. a proxy. The same goes for ajax. The reason that they don't post a crossdomain.xml is because that would make developers put their secret key inside the flex app which can easily be decompiled and compromised. Still it would be nice to have a solution, without having to spin up your own servers.

However, when you deploy to production, crossdomain policy files ARE required. That being said - I think the issue lies with - why when we run test in development no security is required, but then to run the same application from a production site (running the swf in anything other than FB3 test). I (or anyone) may develope a fully functional site in FB3, thinking every thing is hunky dory, then move the SWF to production and crash - no crossdomain.xml file... then, as a developer I have to either 1) contact the publisher of the RSS, API, etc I'm trying to load, and ask them to kindly put up a crossdomain.xml policy file - which isn't likely to happen... or 2) Redevelop how my application loads data (no small thing). It kinda sucks I have to develop around an issue that doesn't exist in development but does in production. I understand the security concerns, but I think it's more on the side of - if I can do it in dev, why can't I do it in production? It'd be nice to at least be able to tell FB3 the app I'm developing will be loading from a site I have no control over which may or maynot have a crossdomain policy file... (ching, ching - my 2 cents)... This is exactly right. I would take it a step further though. If I can get to it with just a browser, then why is it that security is such that I cannot get to it without a crossdomain.xml file that authorizes it. Where is the security hole, if I can just browse to it with Firefox, I.E, Safari, or Opera?

Re: [flexcoders] Re: Need Suggestions for database application.
I actually use PDT: http://www.eclipse.org/pdt/
Now the great thing about this is that I use it as my base and use Flex
Builder Eclipse plugin. So you're doing PHP and Flex in 1 place. I'm not
sure how you want to communicate with the PHP. Personally I like using
URLLoader. There are many other ways to consume data (AMF, WebServices).
I personally prefer to use XML because E4X gives you so much power on
filtering and manipulating data on the client end. Here is the function
I use for retrieving XML:
import flash.errors.IOError;
import flash.net.URLLoader;
import flash.net.URLVariables;
public function loadXML(url:String, vars:URLVariables,
completeFunction:Function):void {
var loader:URLLoader = new URLLoader();
var req:URLRequest = new URLRequest(url);
if (vars != null) {
req.data = vars;
}
req.method = URLRequestMethod.POST;
loader.addEventListener(complete, completeFunction);
loader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
loader.load(req);
}
public function ioErrorHandler(event:IOError):void {
trace(event.message);
}
It just cuts down the rest of my code in other places. All you have to
do then is have your result function specified for example:
public function gotData(event:Event):void {
var xmlResult:XML = XML(event.target.data);
}

RE: [flexcoders] how to avoid cacheing XML
That's a good point--POSTs won't get cached unless something is seriously borked. See also this note from URLRequest docs: === Note: If running in Flash Player and the referenced form has no body, Flash Player automatically uses a GET operation, even if the method is set to URLRequestMethod.POST. For this reason, it is recommended to always include a dummy body to ensure that the correct method is used. The default value is URLRequestMethod.GET. === In my opinion, using a POST for something that's really a GET that you do not want cached is a little more bogus than appending a dummy parameter, but whatever floats your boat. -- Maciek Sakrejda Truviso, Inc. http://www.truviso.com -Original Message- From: Tracy Spratt tspr...@lariatinc.com Reply-to: flexcoders@yahoogroups.com To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] how to avoid cacheing XML Date: Fri, 17 Apr 2009 12:21:21 -0400 If you have control over the server, you are supposed t be able to set html headers that prevent caching, but there are so many server and browser combinations, well, good luck.

[flexcoders] Mousewheel scrolling entire html page not swf.
Wondering if anyone knows how to make the mousewheel just work on the swf not on the entire html page. My swf is embedded in a long html page 1500 pixels in height so when my swf has focus and I use the mousewheel the html page scrolls rather than the swf hearing the mousewheel. Well actually the swf doesn't respond to the mousewheel until the html page has scrolled all the way to the top or bottom. So say I mousewheel down. The html page scrolls until it hits the bottom. Then my swf finally will respond to the mousewheel. The same is true in reverse if you mousewheel up. Any suggestions?

[flexcoders] Re: Need Suggestions for database application.
Thanks Deane Venske and steve for ur valuable guidance, Now the data access ideas are taking some shape. now we have to study PHP first then the PDOs and finally the webORB. As far as PHP IDE is concerned we have to use Some open source solution initially till budget gets approved then we can think of commercial product.But by that time to develop pilot project I think its OK. I also read few threads about PHP vs JAVA as middle tier and found that PHP is not altogether rejected but almost everybody has agreed that its easy to learn, code and development is much faster compared to Java. Exactly this is what is expected from a developer, a fast response. We have decided that initially we will develop our first project with PHP as middleware and if we face some serious probles regarding security, scalability and performance we will think of Java middleware and have taken our client also in confidence he too have indicated consent to this idea. So this is the story at this moment and we are starting to read PHP from tomorrow may a week or two will be required to get things atleast going in PDO and webORB way meanwhile I have question about the third aspect of application i.e. Reporting for that I will open up a fresh thread Hope u ppl also contribute to that also.

[flexcoders] Need Suggestions for Reporting In Flex Applications.
Hello Friends, We are in process of evaluating Flex for Converting a Delphi-Firebird Desktop C/S application to a web application. Till date this list has helped us in two aspects of Application UI and Data access. Now we need help on Third aspect of Application REPORTING. The application under consideration has many reports. All report generating forms accept information from user and that is passed as parameters to Stored Procedure in Firebird and the it passes report data in table format and being printed or saved to disk file. The general features of existing reporting solution we have provided are all reports can be printed in Std Windows Printing mode and fast Dot Matrix Printing mode. Similarly base data for that report can be exported to almost 13 different formats like, doc, XLS, PDF, XML, latex, CSV, Text, ODT, ODS, dbf etc. etc but most popular are xls, pdf, ods and dbf. we would like to have similar functionality in flex also. Can somebody tell us about how reporting is done in flex and mention whether above functionality is achievable in Flex. Thanks and Best regrds. Raja

What I am trying to achieve is create a line chart with two data series,

(google it if you aren't familiar).
When the user mouses over the chart I want to send both data point of

up for the datatip (blank and no gray lines forking out), as I am sending
that hitData info to a function that displays the data series points on
another panel.
So far I have created a custom dataTipRenderer, that is empty, but I
still get the gray lines forking out point to my empty/blank renderer. So it
looks like a gray line sticking out to nothing. Second issue is that I
always want both series to send their data to my datatip function. Sometimes
it sends both if the mouse pointer happens to touch both lines.
I was thinking if I make a custom mouse pointer for just the chart that
is a long vertical line it will always touch both data points, which solves
that problem. Unless anyone has another idea?
The second issue with the gray forking lines I can't seem to get rid of
those little suckers.
Any ideas?

Have you tried loading the .swfs into the same appdomain? -- Maciek Sakrejda Truviso, Inc. http://www.truviso.com -Original Message- From: Erich Cervantez flex@ Reply-to: flexcoders@yahoogroups.com To: flexcoders@yahoogroups.com Subject: [flexcoders] Cairngorm sub-applications Remoting Date: Thu, 16 Apr 2009 17:01:51 - Has anyone written two distinct Cairngorm-based applications, each capable of dispatching service calls (via RemoteObject) and tried loading one inside of the other? Essentially I have a parent application that uses SWFLoader to load a sub-application (in a peer Application Domain). The sub-application loads visually within the parent application but service calls from the sub-application result in a runtime error: TypeError: Error #1034: Type Coercion failed: cannot convert obj...@x to mx.messaging.messages.ErrorMessage. JBOSS logs show this: No destination with id 'null' is registered with any service. The first error appears to be a class-aliasing problem, but both of these apps are Cairngorm-based Flex applications...the registerClassAlias method shouldn't be required (besides, I tried that tactic already to no avail). This is the only Flex-equivalent of a bat-signal I can think of ;) Erich

[flexcoders] Re: relationship of mxml child tags and actionscript
Aaron,
Thanks much for the lead. I was digging into the Flex 3 doc pdf and it seems it
was a little harder to get around;) Maybe just for me...
Have a great weekend!

Geng,
Use the DefaultProperty metadata tag in your AS class. Whatever
property you specify will be the property to which your MXML children
will be set.

Hi,
I am still looking for some general documentations about the
guidelines as to how to write ActionScript custom components. It's
clear that you can expose public properties, styles and event
listeners of your custom components as MXML properties.
But what are the general rules if I want to allow my client developers
to define a property in my custom component using a MXML child tag (as
opposed to a property)?
Like this:
my:MyComp
my:myChild color=0xFF width=300
mx:Label text={data}/
/my:myChild
/my:MyComp
Again, I am looking for _general_ guidelines. Thanks much.

[flexcoders] Re: Need help- cannot insert multiple statements in one SQL transaction.
Okay...
1) use a synchronous connection as async won't work for transactions.
2) yep, use transactions
3) put your statements in an array, not a semi-colon separated string
4) here's the key part of the code I use
connection.begin();
for each (var sqlString:String in sqlArray)
{
statement.text = sqlString;
try
{
statement.execute(-1);
}
catch(error:SQLError)
{
connection.rollback(responder);
}
}
connection.commit(responder);

Air and Flex experts-
I am having a heck of a time getting multiple insert and update
statements to run within one transaction against my Air applications
SQLite db. Only the first INSERT, UPDATE, or DELETE makes it in. I am
not seeing errors, but it seems like it is failing. If I run the same
SQL in another SQL editor, my SQL works fine.
Example code is:
Var myInsert: String = Insert into EMPLOYEES ( NAME ) VALUES (Bob);
;
myInsert += Insert into EMPLOYEES ( NAME ) VALUES (John); ;
myInsert += Insert into EMPLOYEES ( NAME ) VALUES (Fred); ;
var localConnection : SQLConnection = new SQLConnection();
localConnection.open(myDatabase);
localConnection.begin();
var statement: SQLStatement = new SQLStatement();
statement.sqlConnection = localConnection;
statement.text = myInsert;
statement.execute();
localConnection.commit();
I have tried in synchronous and async mode with the same results.
Please tell me what I am doing wrong! :)
Thanks!

[flexcoders] Namespaces/packages problem
I'm trying to create a cairngorm version of my application, as such I've
used the namespace:
com.myproject.cairngorm.*
However as far as I can tell it seems using the name 'cairngorm' in my
project namespace is causing problems with the actual cairngorm swc. I've
tried the below test and found it isn't a cairngorm specific issue...
In a library project I have an interface (or what is IModelLocator in
cairngorm package):
package com.someframework
{
public interface ITestClass{}
}
in my actual flex project I have a class that implements this interface (or
my modellocator in my real project):
package com.myproject.someframework
{
public class TestClass implements com.someframework.ITestClass
{
public function TestClass(){}
}
}
now in my main.mxml file i try:
var test:com.someframework.ITestClass = new
com.myproject.someframework.TestClass();
which gives me the following errors:
1046: Type was not found or was not a compile-time constant: ITestClass.
Main.mxmlNamespaceBugTest/srcline 6Flex Problem
1120: Access of undefined property com.Main.mxml
NamespaceBugTest/srcline 6Flex Problem
Is this expected behaviour and I'm missing something obvious or a flex
problem?
[flexcoders] Re: Namespaces/packages problem
Hi,
Usually you would import the class:
import com.someframework.ITestClass;
and then implement like:
public class TestClass implements ITestClass

Re: [flexcoders] Re: Namespaces/packages problem
Actually Tim, that approach did make a difference in my main.mxml
so this works:
import com.someframework.ITestClass;
import com.myproject.someframework.TestClass;
var test:ITestClass = new TestClass();
whereas this doesn't:
var test:com.someframework.ITestClass = new
com.myproject.someframework.TestClass();
Is that really expected behaviour? I've always believed the above two
implementations to be pretty much the same as far as the compiler was
concerned??
Anyway I'm happy to have it figured out so thanks for responding.

[flexcoders] Custom List ItemRenderer / Recycling troubles
I'm attempting to create a very simple item renderer for mx:List. I've found
that when the dataProvider is static, there are no problems with the custom
item renderer. However, when the dataProvider is dynamic, the height of the
item renderer is not correct. I've set variableRowHeight=true for the List.
I've also tried overriding the measure function and invaliding the size when a
dataChange event is dispatched. So far, I have a multi-line Text component
with word wrap, but the height (determined by textHeight in the overriden
measure) is way to large.
CommentRenderer.mxml:
?xml version=1.0 encoding=utf-8?
mx:VBox xmlns:mx=http://www.adobe.com/2006/mxml; width=100%
mx:Script
![CDATA[
override protected function measure():void
{
super.measure();
measuredHeight = comment.textHeight;
}
]]
/mx:Script
mx:LinkButton label={data.commenter.name}/
mx:Text id=comment width=100% text={data.comment}
dataChange=invalidateSize()/
/mx:VBox
The mx:List definition:
mx:List id=comments itemRenderer=com.test.CommentRenderer width=100%
height=100%/
I've looked over the ListItemRenderer, but have so far been unable to glean the
magic sauce that makes the item renderer function correctly when the control
recycles. Can someone explain why my item renderer height is determined to be
294 pixels, when the Text has only 3 lines (standard font)? What am I missing
here?
