Hi i am developing an device security application. I have implemented lock mechanism using Global screen. For my Lock module i have two Global Screens: 1) Lock Screen 2) Unlock Screen. Lock Screen is global screen with type GLOBAL_MODEL and unlock screen is of type GLOBAL_QUEUE. but when i close the lock screen ,it does not show the Unlock Screen. Later i discovered that it was due to having no screen in display stack. Can anybody tell me , How does global screens are managed in BlackBerry. Does Global screens have any display stack.??
As far as i understand global screen are not pushed into display stack in which normal screens are pushed. Am i right??
i tried to get screen count using getScreenCount method after pushing the global screen, but it returns 0.
