Symptoms

The 'Warn on Unsaved Changes' setting is not exporting.

To reproduce:
Create app name "import test"
Create blank normal page "test" (page 2)
Edit page add static region with one button
The button should redirect to page 1.
For the Button set Warn on Unsaved Changes = Page Default
Run the page and see that the button works, redirects to the home page.
Now export the app, use all defaults
Import the same app, use all defaults
Edit the imported application page 2
Notice that the button has Warn on Unsaved Changes = Do Not Check
The export file does not include
p_warn_on_unsaved_changes => ...
for the button so the default is picked up on import.
