Tree View

Hello,

i want to have a tree view in my BIRT report. I create the tree view in sql with " "*level || String.
Level is the depth.

It looks like:

1
     1.1
     1.2
          1.2.1
2
     2.1

and so on...

My problem is that the names in the report are all onthe left
1
1.1
1.2
1.2.1
2
2.1

Can someone help me please?
I use the newest version of eclipse+birt.

Thanks and Regards
Benni
