Thank you Ahmet for your suggestion..useful 'cause I'm 'new' even to
Java ;-)
Actually I have not solved my problem on Android beta yet.
I still can't open properly my listboxes with 'dynamic content' (that
is filled up by rpc calls to server)
and I cant't click on some listboxes with 'static content' with some
UI configurations
As for listboxes with 'dynamic content' I still see (ONLY ON ANDROID
BETA) the following exception:
[WARN] StandardContext[]Exception while dispatching incoming RPC call
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
bye
