We are upgrading from 2011.1.419.1040 and have the following code:
static bool ExecuteCommandPublic(this
RadDocument document, CommandBase command, Editor.DocumentCommandContext context)
flag = command.Execute(context);
UndoableCommandBase base2 = command
if (base2 != null
Notice that in the 2013.1.403.1050, CommandBase, UndoableCommandBase and document.History.RecordAction are not available and I can't find anything on the website that talks about breaking changes. Can you help?
