public void selectionChanged(IAction action, ISelection selection)
org.eclipse.ui.IActionDelegate
Implementers can use this opportunity to change the availability of the action or to modify other presentation properties.
When the selection changes, the action enablement state is updated based on the criteria specified in the plugin.xml file. Then the delegate is notified of the selection change regardless of whether the enablement criteria in the plugin.xml file is met.

, then this method is not invoked but
