title: ExtJs-4.1 Grid locking + summary feature
body: <p>I am having a grid with the locking feature and the summary feature. 
  If locking feature is used then summary feature doesnt work. Reading the forumns found that when locking is used the ExtJs creates two grid 1. Grid with normal view 2. Grid with locking view. Is it the possibility that the summary feature is not added in the second grid which is created when we lock the columns.</p>
  
  <p>If yes then how can i achieve this ?</p>
  
  <p>I thought Using ExtJs4.1 would help in resolving this issue. But yet I am unable to resolve this thing.</p>
