Hi!

I have a problem with saving a ContentAccessControlList. 

When i create a specific pagetype i want to programatically create a set of containers and subpages and set their access rights. 

Creating a page and its subpages/containers works fine but when i try to set the access rights for each subpage i get this error when i try to save.

System.NotSupportedException: 'Specified method is not supported.'

The Code:

public static void SetAccessRightsForPongChildPages(PageData page, string productCode = null)
{

var pageAccessControlList = new ContentAccessControlList(page.PageLink)
{

new AccessControlEntry("Administrators", AccessLevel.FullAccess, SecurityEntityType.Role),
new AccessControlEntry(ConfigurationManager.AppSettings["EPiRoleAdmin"], AccessLevel.FullAccess, SecurityEntityType.Role)

};

if (page is ContainerBasePage)
{

pageAccessControlList.Add(new AccessControlEntry("Everyone", AccessLevel.Read, SecurityEntityType.Role));

}

if (productCode != null)
{
       pageAccessControlList.Add(new AccessControlEntry(ConfigurationManager.AppSettings["EPiRoleProdOwnerBase"] + productCode,
       AccessLevel.FullAccess & ~AccessLevel.Administer & ~AccessLevel.Publish, SecurityEntityType.Role));

}

pageAccessControlList.Save();

}

I have also tried using pageAccessControlList.Save(SecuritySaveType.Replace);. 

Happy if anyone can point me in the right direction :)
