RE: Returning from a form apge
Thx, My idea was to allow multi-level popup. Jsp1 = Jsp2 = Jsp3 Jsp1 = Jsp2 = Jsp3 ...or any combination...

RE: Returning from a form apge
If you hard code a parameter into the href or page attribute of html:link, it is smart enough to know how to append the other parameters contained in your parameter map. For example if your page value is /myForm.do?ref=1, and your parameter map contains the pairs param1=abc and param2=def, html:link will correctly form the URL: http://www.mycompany.com/myApp/myForm.do?ref=1param1=abcparam2=def -Original Message- From: James Howe [mailto:[EMAIL PROTECTED]] Sent: Monday, April 30, 2001 11:44 AM To: [EMAIL PROTECTED] Subject: Returning from a form apge In our web application, we have two pages from which a user can access a third page.

RE: Returning from a form apge
Title: RE: Returning from a form apge If you are using the MVC design pattern then you will have an action associated with the save. What I have done is keep a hidden field for the referring page, which keeps track of the mapping key. This way I am able to forward to the jsp that originally started the action. -Original Message- From: James Howe [mailto:[EMAIL PROTECTED]] Sent: Monday, April 30, 2001 11:44 AM To: [EMAIL PROTECTED] Subject: Returning from a form apge In our web application, we have two pages from which a user can access a third page.
