Re: Override Input Form / JSP when Errors Are Encountered
Use 'validate="false"' as an action attribute to prevent a return to the input page after a failed validate. Struts will continue on to the action, and you'll need to decide what to do there. - Original Message - From: Jeff Trent To: [EMAIL PROTECTED] Sent: Tuesday, May 08, 2001 3:16 PM Subject: Override Input Form / JSP when Errors Are Encountered When validate() returns an error collection, the framework takes me back to the input page (page1).

Re: Override Input Form / JSP when Errors Are Encountered
Ah, okay. So I should call validate() within the action class directly then? I'll play around with this approach. - Original Message - From: William Jaynes To: [EMAIL PROTECTED] Sent: Wednesday, May 09, 2001 6:58 AM Subject: Re: Override Input Form / JSP when Errors Are Encountered Use 'validate="false"' as an action attribute to prevent a return to the input page after a failed validate.

In
that case try to move your validation into the Action class.

Interesting approach. Let me see if I can
explain this back to you to make sure I understand what you are
saying:
Does your Wizard.jsp look something like
this:
template:insert
template='/template.jsp' template:put name='header'
content='/header.html' / template:put name='sidebar'
content='/sidebar.jsp' /logic:equalproperty='page'
value='1'
template:put
name='content' content='/wizardPage1.jsp'/
/logic:equal...
logic:equalproperty='page'
value='N'
template:put
name='content' content='/wizardPageN.jsp'/
/logic:equal
template:put name='footer' content='/footer.html'
//template:insert
And somewhere at the top you have some logic to
determine which page your on based on direction and error
conditions?
*** I'm starting to feel like I'm at battle with
struts! There must be a way I can hook the error checking logic to
circumvent the redirect to the base input form. I guess its time to dig
thru the source code. What bothers me the most is that I feel like I'm
not doing anything outrageous here.

Here is the way I did it:
I
am using the template approach for the jsp files.
template.jsp is the template file
wizard.jsp has has the template tags
wizardpageX.jsp (where X is a number and corresponds to the number of
screens in your wizard) contains thepresentation.
Inside of the wizardpageX.jsp there are 2 hidden fields (page and
direction). pageholds the number of the page we are viewing
anddirection holds the action we want to take ( next, previous,
finish, cancel).I useJavaScript to update the direction
tag when one of the buttons are pushed. The ActionForm can validate
the input for the page we are viewing based on the direction we want to
go. If there are any errors, we forward back towizard.jsp ( the
input file ). wizard.jsp will look at the page property and decide
which wizardpageX.jsp file to display as the body of the
template.jsp. If there
aren't any errors, my Action object will update the page property to the
page we want to go and forward control back to
wizard.jsp.

Re: Override Input Form / JSP when Errors Are Encountered
Are you suggesting that I put the redirect in my
base input jsp on the condition that errors exist? No offense, but this
seems to be a hacky approach.
Are we saying here that there is no suggested
struts method to handle this situation?
