Content picking issues : any modification on the page properties is not replicated on the destination

Created a linked copy page of a validated page.
Update the ACL of the parent by adding a new user and defining RWA rights for him -> is not replicated in the destination.
Defined a Time Based Publishing on the source, not copied in the destination
Changed the WF type of the source page only in FR and validate it , the WF type of the destination still the onle one (inherited)

tested on jahia 6.0 branch .
