REQUIRED INFORMATION


Ext version tested:
  • Ext 4.0.2 rev a


Browser versions tested against:
  • FF5 (firebug 1.7.3 installed)


Description:
  • If an infinite-scrolling grid has loaded a new page of data and a row in that new data is selected, walkCells(pos, 'up', ...) will only scroll up to the top of the currently loaded page - not the top of the entire data set.


Steps to reproduce the problem:
  • In the Infinite scrolling example, remove the "disableSelection: true" line.
  • Load the example
  • Select a row after row 200
  • Keep using the up arrow to move the selection up


The result that was expected:
  • The selection should scroll all the way back up to row 1


The result that occurs instead:
  • The selection stops at row 176 and will scroll no higher without using the scrollbar


Test Case:
