This is more of a design issue, but I personally hate it (and find it dangerous in some cases) when anything is "automatically" saved for the user without their knowledge. What if I don't want my work on page A to be saved and really just want to go to page B?
In situations like this, I prefer to prompt the user with a message like "Any unsaved changes on this page will be lost. Do you want to continue?" If they click ok, send them to page B. If they click cancel, nothing happens and they are then able to manually save Page A's data before moving on to Page B. You can even be intelligent about when to display this message with some javascript that inspects the form contents (and/or listens to onblur events) and only prompts the user if the form data has actually changed. - Scott -----Original Message----- From: Wendy Smoak [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 27, 2005 4:25 PM To: Struts Users Mailing List Subject: Re: Double submit and Implied Save From: "Nancy Lin" <[EMAIL PROTECTED]> > 1.

I do this by having 'onClick()' on the links submit the current form. Before the form submit, the javascript sets the value of a hidden form element that will tell me where they were trying to go. If there's an error, then the user is returned to the page with error messages. If not, the Action does whatever it needs to do, then decides where to forward/redirect based on that hidden field. -- Wendy Smoak --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
