This issue duplicates another issue.
scrollToEnd on List with variable itemHeight
scrollToEnd(true) does not seem to work on lists with variable itemHeight; it scrolls to the point in the list that would have been the end if all items had the default itemHeight. Is there a workaround for this?
some further digging showed the issue is there are errors occurring while scrolling:
Uncaught TypeError: Object [object Object] has no method 'setMinMomentumValue'
What Sencha Touch 2.x.x version are you using and can you provide a local test case?
Bug seems to have been added to bug tracker already;
The work around offered by hawkinbj doesn't solve my problem though; it prevents the errors, but the list doesn't scroll to end.
