title: Extjs: Delete Row from store-> store.removeAt(RowIndex)
body: <p>I have a bunch of RowIndexes from a store in my GridPanel. I want to delete these from my store.
  If I have only one, its no problem, the view from the Grid is refrsehd and the only entry is away.</p>
  
  <p>But when I have more than 0ne, for example 10 RowIndexes and I make this in a loop like here...</p>
  
  <pre><code>for(rowIndex in indexes)
   {
      store.removeAt(indexes[rowIndex]);
   }
  </code></pre>
  
  <p>...only a few entries are deleted from the grid. I think the loop is too fast?
  I already treid it with a timeout, but doesn't work also.
  Is there anyone who has an idea?
  THANKS!!!</p>
