My framework was targeting Pocket PCs for starters keeping in mind Symbian
and other OSs. I've been using C# because it's a lot easier for me to deal
with screen in C#. I yet have to relearn the ways to do it in Java.
But basically yes, I went down to canvas, getting rid of all PPC controls
except 3 of them: Textbox, ListBox and ScrollBar (not 3 types of controls,
but 3 controls per form), the rest was drawn on canvas. For the first
version I just wanted to get it out quicker so used these controls. 

The framework was not the goal. The goal was to develop a certain class of
business apps really quickly. The app I had in mind would have at least 50
screens packed with data and a database with syncing with enterprise app. No
data crunching but just searching-viewing-editing data - CRM. 
What would you say about developing such an app within one week?
What would you say about UI performance if you had > 50 regular controls on
your screen? My app had a performance of 3-conrol screen :)
It's too bad I didn't complete it :(  But may be some day ...

So Andrei,

It sounds like you tried to implement your own form framework on top of
lcdui.Canvas instead of using the lcdui.Form class.  That's something I've
been thinking about for a while but wasn't going to undertake until I had
someone who wanted to pay me while was doing it. :-)  

Or maybe I misunderstand and you're not using MIDP at all.  Are you
developing for the Personal Profile or one of the other profiles that's in
the CDC?  I haven't tried doing any CDC development yet since I've been more
interested in targeting smartphones and PDAs than set-top boxes and Internet

Heh, truth is, J2ME is easy: it's learning what all the acronyms mean that's
a challenge! :-)
