Displaying errors for all except one key

[Chris Loschen <Ch...@Siebel.com>]

Hi all,

The app I'm working on (using Struts 1.1) has handled errors pretty
simply: they all used to display in one place. However, now we want to
display some errors separately. We've already set up the errors we want
to display separately with their own key, like this:

        	errors.add(RIGHT_PANE_THRESHOLD_PROPERTY, new
ActionError(RIHierarchyMessages.RIGHT_PANE_THRESHOLD_EXCEEDED));

And then we set up the main error display JSP like this:

<%-- Display Error Messages if the showErrors parameter is true --%>
<logic:equal name="showErrors" value="true">
	<%String global_key=ActionErrors.GLOBAL_ERROR; %>
	<logic:messagesPresent message="false"
property="<%=global_key%>">
		<div class="errorMsg"><ul>
			<html:messages id="message" message="false"
property="<%=global_key%>"> 
				<li><bean:write name="message"/></li>
			</html:messages>
		</ul></div>
	</logic:messagesPresent>
</logic:equal>

That works fine as long as the errors are coming through with the
GLOBAL_ERROR key. The special error with its special key doesn't get
displayed, and gets displayed where we want it instead. However, we're
now discovering that we're not getting other errors, specifically the
errors thrown by the Validator. I'm guessing that these are not being
sent with the GLOBAL_ERROR key but some other key, though my Googling
and other research hasn't yet told me which one.

I'd be curious to know what key the validator errors are sent with, but
more importantly, I need to figure out how to display some keys but not
others in my main error display. My best choice would be to do something
like "display any errors with properties that are NOT ..." At the
moment, there is just one property which we need to exclude, but that
could possibly grow down the road.

Does anyone have any ideas? Thank you!
