Refactoring, Error #1065

23 October 2008

I received the following runtime error in a flex project recently:
Error #1065 Variable package::Component_inlineComponent1 is not defined.
I was refactoring away from some static MXML to a dynamically loaded module. I had commented out the static MXML to test the dynamic module. Everything worked great. When I un-commented the previously working static module the […]

Revisiting one of my first RIAs

17 October 2008

I spent some time updating on of my *first* RIAs today.

The application allows special needs teachers to create IEPs (Individual Education Plans) for students. The teachers fill out various (20+) forms that compose the students’ IEPs.
During the initial interviews, it was identified that the forms would be revised annually and […]

Open Source ESBs - It’s Here !!!

17 October 2008

I was excited to find an unexpected package on my doorstep last weekend. I had enrolled in Manning’s early access to Open Source ESBs quite a while ago (last year???). Well the books in print and I’ve got my copy in hand.
I’m currently reading this book right now and loving it!!. […]

The Data Warehouse Toolkit

17 October 2008

I’ve read some really great books the past few months and thought I’d post a review.
I’d highly recommend Ralph Kimball’s The Data Warehouse Toolkit.

I’d normally opt for an architecture book over a [dry] database book without a second thought. Well I was pleasantly surprised to find this great resource.
Kimball gives the reader a GREAT […]

Flex Modules, Watch Your Scope!!

14 August 2008

Here’s another help hint for those working with Modules in Flex: Watch your variable scope!!
When loading modules, you have a number of options for loading the SWF including the ModuleLoader and ModuleManager. If neither of those fit your needs you always have access to Flash’s Loader class. ModuleManger can be used for fine […]

Dashboards… Flex’s ‘Sweet Spot’

6 August 2008

Thanks Adobe!!!
I’ve taken on a number of Flex projects over the past 2-3 years. In that time I’ve used Flex to meet many types of business needs. I’ve spent the last few months working on a enterprise dashboard application built with Flex. This past week the time came for the executives’ ’sneek […]

[Tunkey] BlazeDS + JMS + ActiveMQ

1 August 2008

I spent some time this week with BlazeDS and JMS. I wanted to integrate a Flex RIA with some [existing] backend Java classes. One goal was to interface the two in a loosely coupled fashion, enter Java Message Service (JMS).
The RIA uses a mx:producer to publish messages to a JMS topic […]

AMFPHP Complex Classes - Yeah I knew that

19 June 2008

Just blew half an hour tracking down something I *knew* I’d done before. Thought I’d post here for future ‘lapses.’
To return a typed object from PHP to the flashplayer the process is simple, declare a variable called $_expicitType in your PHP class
e.g.
class SummaryVO
{
var $_explicitType = “com.dl.SummaryVO”;
$standards = […]

Pipe Architecture

13 June 2008

Here’s a working architecture for modular applications utilizing PureMVC pipes.

This allows you to have modules that load modules that load modules, etc. The modules communicate to each other via Pipes.
The sample diagram illustrates a parent, child, grandchild relationship (An app that loads a module that loads module). You can of […]

Two must haves for those ‘rigorous’ developers out there.

2 June 2008

I’ve come across two [free] tools I find indispensable when working under the Windows platform.
Task Arrange
Aqua Dock
Task arrange

Task arrange allows you to change up, on the fly, the order of programs listed on the taskbar.
Aqua Dock

I’ve moved all of my desktop icons off my desktop and onto the dock. No […]

XML => UID Associative Array

25 May 2007

I found myself in need of ‘flattening’ an XML tree. Basically, I needed a means of storing XML elements in to database to search for results at a latter time. The following PHP code transforms the XML tree into an associative array with the following schema
$phparray[’parent.child’][$i] = $value
Where $i would indicate the sibling […]

Suse + Apache sendmail from() address

23 May 2007

Here’s a quick tidbit on setting the [default] from address for php [sendmail] on a suse box. There are *two* settings that need to be changed, let’s look at the default “out-of-the-box” email from address.
WWW daemon apache
The wwwrun is the username that is being used to send the email. (See /etc/apache2/uid.conf). […]

Adobe Flex Upload +[PHP] Session + Firefox = Failure !

20 April 2007

Well not quite but almost. Here’s my dilemma, I have a flex app that allows the user to upload files. My backend PHP script utilizes session variables to ensure the user has the appropriate credentials before proceeding with the upload. When ran under a firefox browser, it appears as though a brand-new session […]

Image cache and Adobe Flex

20 April 2007

Okay, I kept running into the headache of images being cached within my flex application. I found a simple workaround, appending a URL parameter of the current time to the image’s path.
For example, the path img/simple.jpg becomes img/simple.jpg?date=12010103. Each time the page is refreshed, a new date parameter is generated, fixing our cache headache.
The […]
