Hi.
In function upgradeProductVersionStructure(strucutreId, withoutConfirm) of projequtoDialog.js you see the first argument mispelled.
I could be a don't care ( what's in a name ?), but the url argument follows
if (strucutreId)
params += "&strucutreId=" + strucutreId;
Also this could be ignored as in upgradeProductVersionStructure.php the request is mispelled
$strId=RequestHandler::getId('strucutreId',false);

but in function upgradeProductVersionStructure you find also

if (upgradeProductVersionStructureId)
params += "&structureId=" + upgradeProductVersionStructureId;
so you get a mismatch.
You can fix as you like, but I suggest to use the right spelling everywhere.
Best regards
