Flex being relatively new, I suspect many companies hiring Flex developers
don't yet have a Flex project and need someone who can at least develop a Proof
Of Concept. That's what I had to do at my company: in addition to learning
Flex, I also learned Ruby on Rails for the back end (I knew Java
Hi Patricia,
I spent a couple days investigating the various Flex frameworks and finally
came to the conclusion that Mate was best for me. The big Plus is that it
doesn't interfere with your Flex code.
Among my numerous findings, the following two are pretty good:
My Flex application runs in a browser, not AIR, but the concept is the same; it
connects to an Oracle database, via two different server-side technologies
(I've been experimenting for my employer) : Ruby-on-Rails or PL/SQL (using the
Oracle HTTP Server and mod_plsql).
Basically, your Flex
I have chosen the Mate framework, based on the reviews below:

Try Peter Armstrong's Hello! Flex 4 (http://www.manning.com/armstrong3/) once
you've read your Flex 3 books. I read it and found it very useful for
understanding the new things in Flex 4.

The reason for this is explained in Diving in the Data Binding Waters by
Michael Labriola
http://tv.adobe.com/watch/360flex-conference/diving-in-the-data-binding\
-waters-by-michael-labriola/ , but an example using ArrayCollection or
XMLListCollection would be welcome.
Thanks,
Chris.
Although the above discussion about Data Binding is great, you can skip
directly to 28:24 for the short explanation I was referring to.

I open Firebug whenever I type the Konami Code, so it's never really officially
there, but can be helpful sometimes in production...
I use FlexSpy (http://code.google.com/p/fxspy/), but I know there are others.

Hi,
My company's applications are based on Oracle databases and Oracle Forms. I've
built a prototype application using a Flex front-end and Ruby-on-Rails
back-end. And although it works great, my boss is afraid of customers'
potential reactions to Ruby-on-Rails and the whole Ruby + Rails +
Ruby on Rails is interesting because of the little amount of code you
need to write, compared to Java for example. My RoR back end server
deals with the database (Oracle in my case) and communicates with a
Flex front end via XML. Of course, you can use AMF, but in my
situation I don't have such
Hi Juliano,
I'm currently using Ruby-on-Rails as a Server-side interface between
an Oracle database and the Flex client. My employer's not confident in
the whole Ruby/Rails/Mongrel cluster/Monit/Apache or nginx setup... So
the technology you mention interests me. Is there some kind of Web
Server
OK, I'll answer that one myself: yes indeed, the Oracle server now
includes an HTTP server in addition to the Apache HTTP server.
So here's my follow-up question: I did a quick Google search and the
information I've gathered so far seems to say that this technology
might not yet be
Hi,
I deliver data to my Flex front-end via RoR HttpService in XML form. I
realize XML is not the most efficient, and considered using BlazeDS,
but because I haven't yet encountered any performance problems, I'm
sticking to XML to avoid any proprietary format, should I ever need to

Hi Chitra,
I don't know exactly what kind of application you're working on, but I
can tell you how I connect to a database from my Flex front-end.
I use Flex's HttpService to call a URL, which then returns data sent
from a Web Service. This Web Service can be written in Java, since you
seem to
Hi,
Is there an existing function that would allow me to replace
accentuated characters with their ASCII equivalents (e.g., 'à' - 'a',
'é' - 'e')?
I need it so that I can then do a case-insensitive SQL search, after
also converting to upper or lower-case letters.
I could write one from scratch,
Hi,
I've been using MyEclipse + Flex Builder 2 plugin, as well as a bunch
of other plugins (RadRails, Database Explorer, SVN, etc) for about 6
months.
The makers of MyEclipse tell me they don't officially support Flex
Builder. So when I eventually upgrade to FB3, I'm considering
installing the
OK, thanks for your input guys. Looks like I'll stick with MyEclipse
and install FB3 as a plugin, just like I did with FB2. The only
requirement is that I upgrade to MyEclipse 6 (from 5.5.1).
So any way I look at it, I'll have to reinstall plugins...
Cheers,
Chris.
I've solved a similar problem by converting my Windows-1252 content
stored in an Oracle database to UTF-8, directly in the SQL query like
this (the actual method name might be different for your particular
database):
SELECT CONVERT( CODE, 'UTF8', 'WE8MSWIN1252' ) AS CODE,
...
Hope this

Hi,
I'm developing my third Flex application, using Flex Builder 2, and
unlike the first two, I have no *-debug.html or *-debug.swf files... I

Thanks for the example, Tracy.
Hi Tracy,
That's a good idea. Now, I'm wondering what the trade off is between
one HttpService per Component (bigger SWF file size, but parallel
requests thus faster data access on multi-processor boxes?) and one
single HttpService for the whole application (smaller SWF file, but
sequential thus
Being a Flex newbie, I can only think of one way to solve this dilemma
(assuming I ever encounter performance problems at startup):
I thought it was a good idea to implement each HttpService in the
Component that displays the retrieved data, which is saved to an
application-wide Model, accessible
Hi,
Components A and B are inside Panels of a ViewStack; they're accessed
via a TabBar.
I define an HttpService within component A.
I call A.HttpService from an action in component B.
When I perform the action in component B, A.HttpService will only get
called if I have PREVIOUSLY visited A...

You're right, this simple example does work. I still don't know why my
original code didn't work... But I built up this example until I
reached the same functionality as the old code. Unfortunately, I'm
unable to identify the part that made the difference!
Thanks for your help,
Chris.
