Hello,

When we create an app with AWM and after edit the Class sheets and replace on one field this part

$doc.display('content1')

by

$doc.display('content1', 'hidden')

 
we expect to have the edited field hidden. Currently the field still be shown.

It look like that the case is not correctly managed here: https://github.com/xwiki/xwiki-platform/blob/3f7ba76e2dd91a8b71781a474666f451439718ae/xwiki-platform-core/xwiki-platform-appwithinminutes/xwiki-platform-appwithinminutes-ui/src/main/resources/AppWithinMinutes/Content.xml#L79

Step to reproduce:

1. Create a new app with App Within Minutes named 'TestHidden'
2. Add a field of type 'Content'
3. Create a new object with the app
4. Edit the page 'TestHidden/Code/TestHiddenSheet'
5. Replace this line $doc.display('content1') by $doc.display('content1', 'hidden')
6. Save the page
7. View the previously created object
8. See that the field set as 'hidden' are still shown.
