Switch between LCDUI-LWUIT

Hi all,
Although this was mentioned in some Threads I didn't find any clear
explanation / statements from the LWUIT team how to approach this. I
need this in order to get reliable Media capturing, since this just does
not really work with LWUIT currently on quite a few devices (S60 above
all).
So let alone this discussion: how to switch between from to lcdui. I do
it like this. It works in the WTK emulator, but not in my S60 device.
There it my lcdui screen only flikers shortly then comes back the lwuit
screen. I tried a lot of variations, setting current form to invisible
and playing with invoke and block, invoking it in the edt , but nothing
worked, always comes back to lwuit.
Can anyone tell me how to achieve this?
Rgds Ben
Lwuit -> lcdui:
curDisplayable=javax.microedition.lcdui.Display.getDisplay(this).getCurr
ent();
Display.getInstance().getCurrent().setVisible(false);
new Thread(new Runnable(){ .
}).start();
Lcdui -> lwuit:
javax.microedition.lcdui.Display.getDisplay(NuuxMain.INSTANCE).setCurren
t(curDisplayable);
Display.getInstance().callSerially(new Runnable(){
public void run() {
..
}
});

Hi Ben,
we made some comments but obviously nothing "official" since we can't
guarantee a cross device future proof way to do this properly. Event
the native text input which is essentially that is something we
struggled with quite a bit and surrounded with some "ugly hacks".
E.g.: What happens when a background thread tries to show a dialog
when the native form is in place?
How do you handle MIDP's asynchronous setCurrent()?
These are not trivial and still pose problems in some devices when
going into and out of the native UI that are even applicable in the
native text edit. You can look at that code to see what we did
although its not an "endorsement" of that approach...
We use media capture on S60 and other devices so I'm not exactly
clear on why this won't work for you, I recall that you and Chen had
a discussion about exposing the MediaComponent video control. Would
this solve the problem?
Do you have a test case that works for MIDP and fails on LWUIT?

Hi Shai,
Thanks for your Answer. Actually i finally found a hack how to operate
MediaComponent. This was a long long way for me, and i can confirm that
i crashed several S60 phones down in espoo (for the ones that know what
i mean.. )
startCapture();
javax.microedition.lcdui.Displayable d =
javax.microedition.lcdui.Display.getDisplay(NuuxMain.INSTANCE).getCurren
t();
javax.microedition.lcdui.Display.getDisplay(NuuxMain.INSTANCE).setCurren
t(new DummyCanvas());
javax.microedition.lcdui.Display.getDisplay(NuuxMain.INSTANCE).setCurren
t(d);
works finally and the freezing time is over.
Yes i need the videocontrol exposed, but for now i just changed the
lwuit source.
rgds Ben

Hi Ben,
Chen seems to be preoccupied so I'll try to add the video control
change for the next commit myself. However, my commit will take some
time due to the infrastructure work I am doing.
