Subject RE: (sigh!) another pre-populate question

Simon (we meet again)..

Sounds very interesting, but I'm not quite there: 
Firstly I'm not entirely sure what you mean by separating view and edit pages. I'm 
actually trying to write what I think of as an edit page (it basically is setting up some

parameters for a graph). But I need to load default parameters (well its worse than 
that I actually load an existing "user" session bean as the page parameter, as this 
contains all the stuff I need).

Secondly, I do see what you mean by having a PreAction and a PostAction, but I 
don't see how I would set that up in the struts-config. Can you hold my hand a bit 
here, as it where?

One more thing... how does the PreAction actually call the associated JSP. I seem to 
have a problem with this!

Cheers... Howard

fooPreAction does whatever it takes to setup for the foo.jsp (mostly sticking data into fooForm)
and the fooPostAction does the actual processing. In our recent project we observed this pattern
and naming 
convention and it worked quite well for us.
