i have a buffered grid which works perfect in Ext Js 3.4 and 4.07. The data is fetched during scrolling in 100 blocks and displayed in the grid. In 4.1b2 it stops after the first block and hangs. The second data block is ok as i can see in Firebug. I read about this issue here in the Forum before.
Please let me know if there is a fix or a workaround for this. Maybe the API changed?
