Is there a way to associate an ActionError or ActionMessage with a
named key in Struts 2?
In struts 1 we can add ActionErrors / Messages with a named key. The
lines of code below add a new error with the key "login" to the action:
ActionMessages errors = new ActionMessages();
errors.add("login", new ActionMessage("errors.invalidLogin"));
saveErrors(request, errors);
The nice thing about doing things this way is that I can pull out
that single action error if I want, without worrying about the other
errors I might have:
<html:messages id="error" property="login">
<p class="error">${error}</p>
</html:messages>
In Struts2 it seems that I'm stuck with all or nothing. ValidateAware
only takes a single String as an argument for the addActionError
method. The actionerror tag just spits out a list of errors, forcing
me to show all of them.
What is the best way, in struts 2, to associate a non-field error
with a key?
I can see 2 different ways:
1. Just use the addFieldError, even though there is no field for the
error I want to name. (I don't like this approach because it uses the
field errors for something which they are not intended)
2. create my own map of error messages
Thanks for your advice,
