-/** Adds a node of type nt:folder */
+/**
+ * Adds a node of type nt:folder, only on {@link SingleJcrNode} and
+ * {@link WorkspaceNode} TreeObject types.
+ * 
+ * 
+ * This handler assumes that a selection provider is available and picks only
+ * first selected item. It is UI's job to enable the command only when the
+ * selection contains one and only one element. Thus no parameter is passed
+ * through the command.
+ * 
+ * This handler is still 'hard linked' to a GenericJcrBrowser view to enable
+ * correct tree refresh when a node is added. This must be corrected in future
+ * versions.
