A while back, at a previous company, our clients inundated us with feature requests. At one point at the infancy of this software’s life, the codeword for “thank you for your request, we’ll try to get it into the software” was called Possibilities. It always left the door open, however I’m sure the rate at things went through the door and never came back (well not until years later!) possibilities became a dreaded word…

Now however (my personal belief) is between Rails and Flex turning the seemingly impossible to implement round in no time at all. After a rocky road start to Flex, I’m now having the opportunity to develop a full blown B2B application in it. Replacing a PHP/HTML solution. Both exciting and nerve racking - last night a good 2 hours was spent tracking down how exactly to get something shown in the correct order.

I am well impressed, and looking forward to the future of possibilities with Flex 2, Apollo (and what Flex 3 may bring). To share my enthusiasm a good portion of this blog is going to be dedicated to documenting the rebuild of the previously mentioned B2B application.

Currently I have client buy in, after ~ 6 hours of knocking up simple interface showing off a very ‘windows like’ application within a web browser he’s sold on it, so it’s now the big re-write.

Here’s the starting point for it:

- A rails app with database migrations to take the v1 app’s database and migrate it into a rails friendly naming scheme.
- Basic objects replicating core functionality within Rails
- Two flex front ends, one for general order management, and the other a tailored interface specifically for manufacturing.

So far, here’s my pro’s and con’s list

Pro
+ It’s going to work once, anywhere. Flash bugs cross browser are fee and far between. (compare that with XHTML/CSS/JS)
+ More native application functionality (drag/drop, grids etc)
+ Less network traffic per session
+ More responsive application

Cons
- Write, compile, write, compile, write, compile (although Flex Builder/Flex compiler shell reduces the pain)
- A lot more code in building the interface
- Guess work figureing out how to do complex stuff
- Loosing some of Rails niceties (or duplication of things like validations)
