From 603122ef7b866afd7f8353eead5922435b2658db Mon Sep 17 00:00:00 2001 From: Teemu Suo-Anttila Date: Tue, 13 Jan 2015 12:24:54 +0200 Subject: Fix Grid handling state changes and RPC calls deferred (#16188) Some column changes in Grid were not correctly handled by the RpcDataProviderExtension. These cases are now correctly handled.
