Description

Do not call the UpdateTarget method. This method is called automatically so that actions can update themselves according to current conditions. 

In TEditSelectAll, UpdateTarget checks whether Target is a text control that contains text. If so, UpdateTarget sets Enabled to true. If not, UpdateTarget sets Enabled to false.
