title: ExtJS 4 - Update/Refresh single record
body: <p>I have a problem that's bugging me.</p>
  
  <p>I have a grid and when i dblclick on a item I want to open a window to edit that item. Pretty standard stuff. The problem is, i want to be sure the record is up to date, because other people using the program may have changed it or even deleted it.</p>
  
  <p>I could reload the store, but i only want one specific record to be checked... So i figured i would just go get the data, build another record and replace the existing one in the store but i really want to know <strong>the best way</strong> to do this</p>
  
  <p>Bear in mind RESTful proxy is not an option for me, even though i don't know if the update operation works in this case ( server -> client).</p>
  
  <p>EDIT:
  this may help somebody: 
  all i did was copy the data and raw objects from the new record to the old one and then "commit" the changes. worked for me.</p>
  
  <p>Thank you.</p>
