ME 3.0 on java SE works OK

You can observe problems like taht (missing softkey bar) with GPL midlet MC2:

I created test midlet from eclipse samples (in MTJ). I'm attaching eclipse 
project for your testing.

The issue is following - after splash screen, an empty canvas is shown with 1 
command "exit". The softkey area with "exit" command is shown OK in ME in java 
SE, but after converting to android app, the softbar is not shown. I think it 
is the same issue.

The TestCanvas.jad can be found in 'deployed' folder

In the TestCanvas.zip case the exit command is removed automatically by the 
MicroEmulator. We decided to remove Command.EXIT commands because Android 
applications doesn't exit by design.

If you test LWUIT application on ME 3.0, what happens when you press the menu 
button? Can you observe the commands overlay sliding up on top of your canvas?

nothing happens when I press menu button, and LWUIT screen works as usual 
(focus remains there, arrow keys change selected item). Looks like menu button 
(and BACK) are ignored.

It might be that on Android platform LWUIT uses runtime check how to render the 
softkey bar which is not compatible with ME. Which version of LWUIT do you use?

Yes, it might be. I use LWUIT 1.3 but I took it from SVN, and I think it is 
almost 1.4. I think it should be the same for the official 1.4.
with ME 2.5 it was rendered OK, so it may be an issue on ME side as well.
Also, there is not only softbar or screen size issue - other parts of screen 
are not painted (and get painted after I move selection on LWUIT screen, so not 
painted areas gets updated later). See attached
