Issue Summary

Hierarchy is lost when you create a child page before publishing the "draft-parent" page.

Steps to Reproduce

Version 1 

• Visit page A
• Press the 'Create' button
• After the new page draft opens, press the 'Create' button again
• Give the new page a name 'B' and 'Publish'

Version 2 

• Visit a page 'A'
• Press shortcut 'c' and keep the key pressed.
• Wait until at least 2 page loads did occur
• give the new draft a name 'B' and 'Publish'

Expected Results

• Confluence will not allow you to hit the "Create" button if you haven't published the page.
• New page with hierarchy: A -> B

Actual Results

• On Page Information the parent is listed as "$webwork.htmlEncode($content.displayTitle)".
• Checking internally in the database, the first page(Page A) will be a draft without title, hence causing the "$webwork.htmlEncode($content.displayTitle)".

Notes

• After updating the null entries and rebuilding the ancestor table, the problem is still not resolved as it was created a page from a draft.
• The page can be put back into the page hierarchy by simply doing a 'move' on it, and selecting a regular page as the new parent.

Workaround

A workaround for this is to move the child page to a new parent page temporarily and then moving it back to it's original location
