Re: [flexcoders] Re: Webservice Random Faults

2010-02-24 Thread ArunKumar Madas

I am afraid having to do that will defeat the purpose of having webservices
in place!
To me it alternately looks like having HTTPService with required params to a
CF page that queries the db and returns the data back (in your case its via
AMF using remoteObj).
In-case someone is looking for an answer -

  I spent a lot of time trying to dig through the framework api with debug
points everywhere. Its unfortunate, i was in a place where finding the cause
of the problem was a pain as the faults were not consistent and any code
changes cannot be tested without it being reproducible. I read in the
comments of this url - http://www.judahfrangipane.com/blog/?p=87 that
getting rid of fiddler sometimes avoids these errors. In my case these were
not the IO errors (#2032) as i receive the HTTP status codes fine 200 in the
response in fiddler. I just couldn't give a straight solution to get rid of
fiddler without the issue being reproducible.

 While i debugged through the framework, i figured out that error was
getting generated from mx.rpc.AsyncRequest.as (Line 62) and the
acknowledgement forwarded by fiddler has DSErrorHint set to true. This is
the catch to isolate why fiddler receives the HTTP status 200 fine (acting
as proxy) just that it doesn't reach through till flash player fine. One of
the QA Engineers reproduced the problem in-house and I have witnessed having
fiddler on (acting as proxy) causes the problem and turning it off gets rid
of it [I was really lucky to reproduce it, it was like one out of 30-40
operations faults]. Hard to even convince any one even now, but hope this
saves someones time.

Use network sniffers instead of http proxies for debugging.

Re: [flexcoders] Label help

2010-02-24 Thread Jayant C R

One way to solve your problem is to position the dots behind your label and
make the backgrounds of your labels opaque so that your labels cover part of
the dots and give the appearance that the dots extend from one label to
another.

1) Add a label containing just , as long as
the width available for the two labels.
2) Add your two labels so that they're positioned on top of the above label.
3) Set the opaqueBackground color of your labels to 0xFF (or whatever is
the right background color)

Hope this helps,

In a non related thins you shouldn't have view refereces in your model -

[flexcoders] Flex 4 - hover issue on itemrenderer OR data property for group. Take your pick

2010-02-24 Thread rdm0004

I've created a repeated custom component in a data list via Flash
Catalyst.  The component has 4 custom states that change the appearance
based on a global variable.  It generated the component as a s:Group and
the states worked just fine, but the s:Group did not have access to the
data property even though it was assigned as the itemRenderer in the
list.  So I changed the component from s:Group to s:ItemRenderer and had
access to the data property.  However, now when I roll over a component,
it changes it's state to the first defined state in the s:states
declaration.

So I need to know how to override the hover state in an ItemRenderer so
that it leaves the current state in tact, or how to get access to the
data / owner properties if using a s:group as the itemRenderer.  Many
thanks!

2010-02-24 Thread Jeffrey Vroom

Hi Kevin,

On your specific bug, the bug below where this error occurred improperly was
fixed before I left Adobe. It could be a simple problem in your
configuration or code. When you use sub-types in Java with hibernate and
LCDS, you need a corresponding type hierarchy of ActionScript classes. If
Foo extends Bar in Java and both are hibernate model classes, you need a
Foo.as which has its remoteClass alias set to Foo.java and similar for Bar.
You might also check the XML downloaded from the server at the time this
error occurs. It is in flex.messaging.config.ServerConfig.xml (a static
property). If you dump that out you should see destinations which match up
with the type hierarchy for your model.

occurs with the combination of the deleteItem and the commit(item)
or commit([item]) case. The code is trying to look up the DataService
associated with the item in the argument... to do that we look in the
cache for each item. We can't find it (since it has been deleted) and
the code is improperly returning the last data service in the list.
So when it works, it is because the list of data services is generated
in some particularly lucky order.

If you can commit everything - not just that item, that would be an
easy workaround though most likely you are using that variant of
commit for a reason.

I'll contact you off-list to get you a patched fds.swc to try out
the fix. For your reference, the bug number I filed is:

https://bugs.adobe.com/jira/browse/LCDS-351

Subject: [flexcoders] LCDS: Problem with destination inheritance

Hello,

I'm using the latest LCDS 2.6.RC1 with the HibernateAssembler and a
non-trivial data model that relies upon destination inheritance in a
few places.

In general everything works great, but occasionally, when I remove an
element from a collection using dataService.deleteItem, when I then
call dataService.commit, I end up with an exception that indicates
that the wrong destination is being invoked...

For our purposes, let's just deal with 4 destinations:

Folder
ResourceFolder (extends folder)
Meeting
MeetingParticipant (is a many-to-one child of Meeting)

Now, if I call:

meetingParticipantDataService.deleteItem(meetingParticipant);

meetingParticipantDataService.commit([meetingParticipant],true);

I end up with the following exception:

== begin exception

Error: Destination: spring.folder received an instance of class:
demo.model.meetings::MeetingParticipant but we could not find a
destination in the list of sub-types: spring.resourceFolder which
extends this destination.

[flexcoders] Missing component in flexbuilder 3

2010-02-24 Thread aceoohay

I created a a component called ValidatedRadioButtonGroup. Intellisense finds 
it, I can use it and everything is good.

Flexbuilder does not show it in the components panel. Which means I can't 
easily drag it onto forms during development.

Any ideas?

Re: [flexcoders] Missing component in flexbuilder 3

2010-02-24 Thread Tim Statler

That typically means that the custom component doesn't extend UIComponent or
another Flex component based on UIComponent. If it already extend one of
those types, I'm not sure why else it wouldn't show up. What SDK/Builder
version are you using?

You shouldn't need to do this.  Try setting the minimum and maximum values on 
the date time axis to the desired dates and it should do the rest(regardless of 
which dates there are data for).

I'm not sure I quite understand the question, but a couple of thoughts:

- if you have a data function that returns null you can get gaps in a line 
chart, if that's desired
- on the other hand, if your data provider filters out the empty data points, 
the chart should fill the available space
- I think you might be able to have a separate data provider for the axis

In other words, I would be surprised if custom renderers are necessary.

[flexcoders] Accessing 'change' property in a dynamically-created TextInput.

2010-02-24 Thread Laurence

Suppose I have the following code:
 var myTextInput:TextInput = new TextInput();
 this.addChild(myTextInput);

How do I access the 'change' property of that TextInput?  If I try:
 myTextInput.change=myChangeHandler()
it gives me a error:
 Access of possibly undefined property change through a reference with 
static type mx.controls:TextInput.

So, how do I tell that dynamically-created TextInput what to do when its value 
is changed?

[flexcoders] Re: Binding Issues with ArrayCollections

2010-02-24 Thread chefbrittison

I'm not actually referencing the view with the 'modelLocator.view.fields' 
statement.  That's kind of confusing but the code is for a View Builder 
application so the view in that context refers to a View model class.  
Listening to COLLECTION_CHANGE events works fine and from reading other posts, 
I'm guessing is more performant?  I knew there were binding issues with updates 
to an item within a ArrayCollection but I thought adding items worked as 
advertised.  Anyhow, thanks for your help.

[flexcoders] LCDS / Tomcat - Fill Data Not Returned

2010-02-24 Thread headj...@bellsouth.net

I have a question regarding LCDS and Tomcat.  My sample application runs fine, 
but I notice that after a period of time data is not returned.  Looking at the 
Tomcat window I see the query executing successfully and data coming back.  But 
the data never appears in my data grid.If I restart Tomcat, everything 
works fine again.

Has anyone else noticed behavior like this?  Is it an app memory leak that is 
causing it or a timeout (like session timeout) setting?

Thanks,

Hi Nick,

This will get ugly quickly as this isn't as easy as it sounds, pardon the pun. 
;)

You need to do some pitch-shifting to the audio stream before sending it along 
to play.

Here's a good discussion on it
http://www.dspdimension.com/admin/pitch-shifting-using-the-ft/

Here's a working java sample which you might want to play with before porting 
it over to as3 unless you want to just convert prior to streaming

http://www.mediafire.com/?ze3mymjguim

Let us know what you end up doing as this could be a nice AS3 component.

Thx,

[flexcoders] Group displaying label for all dates in a month, or a range of date?

2010-02-24 Thread Vishal

I am using candlestick charts with category axis on the horizontal for 
displaying date, now I want group displaying the label for all the dates in a 
month or a range of date.

For all dates in Feb, I should display one label 'Feb' and similarly for other 
months.
or
For some dates like Feb 2, Feb 3, Feb 4, Feb 5, Feb 6 label should be Feb 2 - 
Feb 6


Once achieved I want to draw grid lines separating the labels formed in the 
above example.

Any pointers?

Re: [flexcoders] Strategies for switching between testing and deployment addresses

2010-02-24 Thread Tim Romano

I'm too new at Flex to do anything fancy like reading files from the O/S 
file system, so I use the Project compile option.


-locale en_US -define=CONFIG::debug,true

Then I have me some constants:

   public static  const DEBUGMODE:Boolean =  CONFIG::debug;
   public static const DEBUG_BASEURL:String = http://localhost/foo/;
   public static const RELEASE_BASEURL:String = 
http://www.somedomain.com/foo;;


And then in my wrapper for the HTTPService:


if ( SearchConstants.DEBUGMODE) {
baseURL = SearchConstants.DEBUG_BASEURL ;
}else{
baseURL= SearchConstants.RELEASE_BASEURL ;
}

All you have to do is change the compiler settings to debug, false and 
-- voilà -- or wa-la if you like that better. There's still the 
forgetting to change the compiler options issue, but it's probably a 
good habit to examine the Compiler options before each compile, and this 
approach inculcates a good habit.


Take this with a grain of salt; I'm new to Flex; my expertise, if I have 
any at all, is not in Flex programming.

Regards
Tim Romano

Or at least I mean to. It's all too easy to accidentally change the

Is there a best practice or simple strategy for putting the IP address
somewhere outside of the source code that it can easily be edited
without a rebuild?

Thanks for any advice.
