Ext version tested:

  • Ext 4.0.2 rev a

Browser versions tested against:

  • FF5 (firebug 1.7.3 installed)


  • 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

Debugging already done:

  • line 885 - if the grid has loaded a new page, "row === 0" doesn't necessarily represent the top of the data set.

Possible fix:

  • not provided

Additional CSS used:

  • only default ext-all.css

Operating System:

  • Windows Vista Enterprise
