title: get current page of paging toolbar ext js 3.4
body: <p>I'm using EXT JS 3.4</p>
  
  <p>How can i get the current page of the Paging Toolbar? </p>
  
  <p>For example paging toolbar says page 7 of 10. How can I get the value '7' because I will need the current page value after the records in the Grid are refreshed. </p>
  
  <p>My problem after refresh on the Grid, it returns to page 1 instead of page 7 where I left.</p>
  
  <p>Thank you.</p>
