Grouper Users - Open Discussion List

 Now I am working on the new grouper v1.2. 
 
After I finish all the configuration and building, I start to add root stem 
and wheel group by using the gsh tools. And I add some person subjects and 
attributes into the postgres database by excuting sql scripts. Then I added 
one subject into the wheel group by using the gsh command "add member". So it 
works. And then I access the grouper administration system by login the ui. 
And I created stems and groups smoothly. But then the weird thing happens. 
When I searched subjects by using the searching tool in the ui, I found 
nothing turning up except the groups that I have created. The database 
contains the person subject infomation, but the searching result for the 
person subject is empty on the jsp. As a result, I cannot add members to the 
groups.
     if I access the url such as:  
        populateSubjectSummary.do?subjectId=someid&subjectType=person
     I can get the Subject summary  corresponding to the "someid".

     When I used the grouper qs-start database hsqldb, I found it's ok to get 
the subject searching result. Is there something wrong with my initialization 
steps?     
 
    BTW, the platform I work on is windows XP. And I use tomcat 5.5.23 as the 
container for grouper ui. Database is postgres.
