I just switched from 1.1.1 to the 1.2.0 beta and really like the model-free grid.
However, I ran into a small issue with numeric autoHeight - the grid's content gets resized away when the number of rows is the same as rowsPerPage.

It looks like grid/_Scroller.js (trunk line 244):
var rowsOnPage = (this.page < this.pageCount - 1) ? this.rowsPerPage : (this.rowCount % this.rowsPerPage);
should be something like:
var rowsOnPage = (this.page < this.pageCount - 1) ? this.rowsPerPage : (this.rowCount % this.rowsPerPage) || this.rowCount;?

test case is basically autoHeight=5 in grid/tests/test_data_grid_autoheight.html with rowsPerPage=7 (have a file but couldn't figure out how to upload it)

Thanks,
Yori
