We also have a pattern for many situations where we encapsulate our
page-centric handling into a single action where for example a GET into
the action sets up the page, and a POST to the same action for form
handling but to a different method in the action. Our approach to avoid
validation on the Get is that we have taken to writing most of our
validation as java code in the validate() method of an action that
implements validation aware, and have gotten away from plugging in
validators to objects for this particular reason. So what we do is:
public void validate() {
String actionMethod =
ActionContext.getContext().getActionInvocation().getProxy().getMethod();
if
(actionMethod.equals("myActionMethodConfiguredAsTheFormPostTarget")) {
// do some validation
}
}
This also allows us to delegate validation to other classes needed to
handle more complex validation scenarios.

Subject: Re: How to avoid validation if request was done by GET method?
hi boraldo
a very simple way should be:
Action:
YourActionConnetedToTheFormAction extends Action..{
execute(..){
String qString = request.getQueryString();
if(qString!=null && paramsFound(...))
// *paramsFound() = check if your formParams were given by query
String
}
else {
//check if your formBean is set (depends on the scope you have set in
your struts-config.xml)
//e.g.
if(request.getAttribute(yourForm)!=null) {
yourForm.validate() {
}
}
}
}
should work ;)
