Portlet preference unique for user
Is it possible to make portlet preferenc unique per user?

In order to make preferences user specific in liferay, I add following entries to liferay-portlet.xml and tried with adding in portlet.xml.

<preferences-unique-per-layout>true</preferences-unique-per-layout>
<preferences-owned-by-group>false</preferences-owned-by-group>

or

<preferences-unique-per-layout>false</preferences-unique-per-layout>
<preferences-owned-by-group>false</preferences-owned-by-group>

so, if i login through two different user i can see both preference set differently. but if any user changes the preference is changing for both user.
It is not working, pls help me.
thanks in advance.
