[FIXED] [#872] [3.2.1] GridPanel View EmptyText
Hi,
I need to display a "No records to display" message hiding the headers within the GridPanel View when no records are present in the Store. Once the Store is reloaded with some data, either on the client or on the server, the message should disappear and GridPanel should present its headers back normally. A code sample to begin with is below. Please advise.
