What steps will reproduce the problem?
1. Create TreeGrid with more than one page of data
2. Click on a page link

What is the expected output? What do you see instead?
The data for that page should show. Instead, the data for the first page
always shows regardless of what page number you click on


What version of the product are you using? On what operating system?
1.4.7 with Firefox 3.5.x and XP

Please provide any additional information below.
I believe the bug is in TreeGridRenderer's drawContent() on line 70.
Shouldn't it be getting row "i" from the model instead of row "i - start"?
This is what DefaultGridRenderer does and paging works correctly in
DefaultGridRenderer.
