In my portlet filter i want to create a filet from lookup which fetches data depending upon the project instance i am in but it seems project instance based filet is not working. It tried using following in my lookup query for parameter @WHERE:PARAM:XML:INTEGER:/data/param_inv_id/@value@
@WHERE:PARAM:XML:INTEGER:/data/id/@ etc.
Note: The same lookup is working if I am creating at attribute within project object by using this lookup but not in filter.
Can someone help me in getting instance based data in portlet filter?
