Renaming page/space gets wikiname in parent

Hello,

if I make a page the $doc.parent of this page looks like: space.space2.space3.WebHome

If I rename the page to a different space the $doc.parent looks like wikiname:space.space4.space3.WebHome

This causes livetables with the extraparam=$parent=${doc.fullName} to stop working.

To get it working I have to switch to extraparam=$parent=${doc.wiki}:{doc.fullName}

However If I have both renamed as non-renamed documents in a space. I do not see both.

How can I correct this behaeviour or is this solved in a later version of the XWIKI. (Using XWiki. Enterprise 8.4.4)?

Anyone an idea?

Thank you
Jurjen
