[Forums] Why can a List only be a Input parameter on a screen if the screen is Non-Public?

Hi All,

When you want a Input parameter of the type (Integer, Text, Boolean etc) List on a screen that has Public = Yes this error occourse:

Invalid Public Screen

Screen 'HomePage' cannot be public because 'In1' input parameter type is RecordList.

Why is this? I can't find any documentation why this is not allowed.
Kind regards,
Martijn Habraken
