Hi Hamid,
I have created xFrgaments on below path:
/content/experience-fragments/test
path is : /content/experience-fragments/test/experience-fragment/master
on editing page property, save&Close button has following url appended to it
'/sites.html/content/experience-fragments/test/experience-fragment'.
Hence its redirecting to this URL.
I tried to debug more by going to this path-/libs/granite/ui/components/shell/propertiespage/propertiespage.jsp
Here value backref will be -${empty param.backHref ? (empty header.Referer ? granite:concat("/sites.html", granite:encodeURIPath(granite:relativeParent(param.item, 1))) : header.Referer) : param.backHref}
incase of empty 'header.Referer ', above url gets added. I am not very clear how we get this value
