adding an ActionError in the Action

Hi,



If I form validates itself OK but subsequently the Action needs to raise an
      input error to the user, in my case security failed, how is it
      possible to add an ActionError for the errors tag to pick up. The
      only way to give struts a collection of ActionErrors is by returing
      it from the ActionForm.validate() method.



I presume if I know the name of the ActionErrors bean which the error tag
      accesses I could manually create it in the Action and add it to the
      correct scope so that the errors tag could pick it up.



Has anybody encountered this problem before?



Cheers,



Andy S

There is a method in the Action class you can use to do this: saveErrors(HttpServletRequest request, ActionErrors
errors).
You can also do directly :

request.setAttribute("org.apache.struts.action.ERROR", errors)

So all you have to do is create an ActionErrors object, put errors in it, save it in the request and return (new
ActionForward(mapping.getInput())) to return to the form.

This is illustrated in the example application.

Have u looked at saveErrors() method of Action object. It should do the
work that you wish to do, just remember to use the errors tag in your page
