Action on user command for dialog screens
I have module pool program with four screens, 100, 200, 210, 300
from screen 100 I call 200, then I call dialog screen 210 to rais question to the user, then based on the user answerI call screen 300 .
Now the case: when I click on back button from screen 300 it take me to 210 where it should go to 200, then I changed the code from leave to screen 0 to leave to screen 200, but I faced another problem that when I click back in the main screen 100 I have to click back twice to leave the program. how possible to clear the user actions or buffer.
