Extjs4. Restore previous filter result

I have in a viewport a textfield that it is for searching purpose. I have also a store that holds the data from the search queries. When user conducts a search and if query has results the store is populated with records. Each time user makes a search the store is updating with the new records. It is likely that some queries will not return results. So, what I want is when the search query don,t return any results not to update the store but retain the last successful query results. How can I do that?

Thanks

Tom

  • Declare a global variable and update it conditionally.
