[Laszlo-user] Laszlo Development

[Andrew McLaughlin]

Hi Aaron,

Looks great and sounds like something that might help my project. So  
this tool then starts with a basic database definition and builds  
Laszlo code? If it at least builds the framework and makes it look  
nice, I can hire someone to update the Laszlo to tidy up, add  
appropriate Ajax calls for data queries and interface to the  
controller and model layers.

Do tell more...

I'll check out the dev site as well. Any screen shots of example apps?

Andrew
