Re: To Aaron: Re: want to have errors to be displayed in different page

Hi Jenny,

The html:messages tag by default will iterate over the ActionErrors 
stored in request scope under key org.apache.struts.action.ERROR.
The value of the id attribute is just the name you want the tag to expose 
each individual ActionError/Message under. The docs do a better job of 
explaining this than I can. Here's a link to the piece you want to look 
at. http://jakarta.apache.org/struts/struts-html.html#messages
If that still doesn't clear it up take a look at the source for 
MessagesTag. The doAfterBody() method is were the value of the id 
attribute is used.
