[Laszlo-user] Big pluses and minuses of using Laszlo?

I was working quite a bit long with trying to site using OpenLaszlo. (close
to one year)
At first, I was excited the possibility of having dynamic flash at my
disposal using opensource tech ( no license fee), and for the first time I
can skip learning actionScript. Fast forward to today, I found that Laszlo
has its strength and weakness.
I found the Geert blog plus several responses summarized them pretty well.
I think the best way is to combined several technologies and make them
work. My approach is to do the hybrid way.
Laszlo is good at creating web 2.0 application, but weak at creating
complex animation. I use OL to be the manager and use Flash Actionscript
for heavy animation. Since Laszlo can easily load any valid swf, this
proven to be my winning combination.
In addition to that, I use RubyOnRails to produce the html and generate the
parameters to be passed into Laszlo.
For example on my still work in progress website (http://newavenue.net).
While all of the menu and some minor animation is handled by laszlo, I
used Macromedia tools to generate more complex animation.
Then I have programmed it using ruby on rails passed the flashparam that
later is used to by laszlo to decided which animation to load.
- Laszlo is good for data intensive application and not good at creating
- Macromedia Flash/ Actionscript is best on handling complex animation, but
difficult to create web application ( no object oriented,...)
- RubyonRails is an excellent glue that integrate both of them.
My next experiment is working on data intensive laszlo web application. I
hope my approach still working against the heavy XML /REST heavy apps.
Just my $0.02
