I looked at the code and noticed that the values entered were not there after I had activated another screen.

The resons for this are that the data
AknExSettingListData is reinstansified AND
AknExSettingsListbox::StoreSettingsL was not called.

I spent 2.5 working days to figure that out ( mainly because i was looking for how to add that functioality, not how to fix the bug) , so I decided to write it here, so someone else might save that time...
