RE: Validation + multiple Submit buttons
This works perfectly, a simple action to check which submit button is clicked
forwards the three pages without validation to appropriate location.
Actual Save button calls a commit action where validation is required.
Thanks for the help

Hmm... that makes things more interesting.
How about this:
You create a new action called "figureItOutAction" or something like
that, and POST your form to that action. This action has no form bean,
no validation, no nuthin'.
In that action, you look for the names of the buttons that you want to
use, say: SAVE, BACK, CANCEL, and FOURTH_BUTTON (or whatever). Then, you
dispatch based upon the button that was pressed:
in struts-config.xml:
.
.
.
Remember to definitely NOT set redirect="true", since we need the reques
to stay in tact.
Your code for FigureItOutAction will look like this:
if(null != request.getParameter("save"))
return mapping.findForward("save");
else if(null != request.getParameter("back"))
return mapping.findForward("back");
.
.
.
Then, just point each of these dispatching actions to the ones that
really do the work. Each of these may have validation, form beans, etc.
For instance, your "save" action (or "next"... whatever) will have a
form bean and validate="true" in struts-config.xml.
This trick allows you to submit your form to an action which decides
what to do independently of validation. Forwarding on to another action
that /does/ validate will then give you the magic of validation.
I haven't tried this before, but it should work.

I think that JS is nice to use in order to improve the user experience, but relying on it to work is a recipe for disaster.

Re: Validation + multiple Submit buttons
Use a Cancel button http://struts.apache.org/1.x/struts-taglib/tlddoc/html/cancel.html from javadoc Renders an HTML element of type submit. This tag is only valid when nested inside a form tag body. Pressing of this submit button causes the action servlet to bypass calling the associated form bean validate() method. The action is called normally. see also http://wiki.apache.org/struts/StrutsUpgradeNotes128to129 mas Andrew Martin wrote: Hi, I have just begun to add validation to my forms using struts validator, which is quite nice.

This is done differently depending on which content-builder you are using (JSP, Velocity, or whatever), but basically you have to end up naming the button "org.apache.struts.taglib.html.CANCEL", which indicates to struts that validation should be skipped.

That is actually not too far off what I have at the moment, except I currently
use to saveAction for all the submit values
I will give it a go.
