Thanks for the feedback Martin.
This is a really generic issue to me.
I have a list. From the list you can do operations. When you complete the
operation you want to go back to the list.
Success or error, you want to go the list with a message from the first
dispatch.
Another example would be having a [delete] link on each row of the list.
You click [delete], it fails because the page was stale, so delegate to the
list() dispatch with the error message from delete().
I am asking for a best practice because I can make this work in several ways,
none of which seem clean.
This seems like the default behavior of any list page to me. I am hoping there
is a prescribed flow to follow.
There are a couple options that I can think of:
1) go to error.jsp
This is really not desired.
Going to a default error page (or even a custom one) is breaking the workflow
of the user.
They see the error and next need to click back to the list so they can try
again.
2) call list() as the return import().
This works fine, but now there is hard coded "chaining" logic.
3) pass my own parameter in the result action tag in struts.xml.
Ex. <param name="myErrorMessage">${myErrorMessage}</param>
This is not desired either. It basically means I am replacing the existing
error framework.
All my JSPs would need to look for myErrorMessage instead of using the built in
tags.

dispatch (struts2)?
your action execute method can return "error" result which maps to error page
e.g.
<result name="error">/error.jsp</result>
where error looks like
<html>
<body>
<b>YOU have an error !</b>
</body>
</html>
better to create a div tag and write a meaningful error to response which
displays response in div tag ...

Anyone else?
