When a new page being created hasn't been saved yet, it doesn't show up in the treeview thus no attachment can be added

• XE 1.8.1
• Create a new page in syntax 2.0
• Try creating a link towards a file attached to the current page
• The current page doesn't show up in the treeview

Expected behavior:

• Display the new page in the treeview and let the user upload an attachment to it
• If the user hits "Cancel" after uploading an attachment but without saving the page, treat the page & attachment as if they had never existed and delete all their contents
