unable to resafe file with gedit if it is not automounted (solaris 11.2/zfs)

Dear all,

I am not able to safe files with gedit unless i use an automounted link to the folder.

i was touching a file in my home directory and open it with gedit:

i can change the content and resafe the file --> This works

The folder is automounted on the path /home/<user>

if i open the same file at the physical location /ex1/safe/home/user i can't safe it with gedit.

I am able to change it using vi

I am able to change it using bluefish but not able to create a backup file

This belongs also to all other folders, not only Homedirectories i automount.
