ActionMessage is a super of ActionError. ActionMessage was added in 1.1 because the name ActionError implies that it shouldn't be used for general information or warning messages. So I guess that it makes you "feel" better using ActionMessage. The ActionMessage is used exactly like the ActionError except that it can represent a less severe message that needs to be displayed to the user. So it's only more appropriate.... if it's more appropriate!
