Hi,
I am testing the microemulator version 3.0.0-SNAPSHOT.72 with a MIDlet that comes with the default installation of the Sun Wireless Toolkit, the UIDemo MIDlet suite, and I have found than when it executes "display.setCurrentItem(parent);" in a Nokia phone, the execution changes the current displayable to the given one but it doesn't happens in the microemu.
Checking the specs of this method, it must occur like in the Nokia phone:
Requests that the Displayable that contains this Item be made current, scrolls the Displayable so that this Item is visible, and possibly assigns the focus to this Item. The containing Displayable is first made current as if setCurrent(Displayable) had been called.
Best regards,
Jose
