Can't input anything into EditField!

I created a J2ME Application for Blackberry phone and initially, I have this piece of code which is to detect when user presses the ESC button.

//When application closes
public boolean onClose() {
System.exit(0);
return true;
}

//When user press ESC key OnClose() would be called
public boolean keyChar(char key, int status, int time) {
if(key == Characters.ESCAPE){
onClose();
}
return true;
}

However, when doing this, I faced a problem of allowing the user to input anything into the EditField!!
So I just had to add this piece of line in the keyChar method to make it work :)

return super.keyChar(key, status, time);

You keyChar method should now look like this:

//When user press ESC key OnClose() would be called
public boolean keyChar(char key, int status, int time) {
if(key == Characters.ESCAPE){
onClose();
}
return super.keyChar(key, status, time);
}

Problem solved! :D
