I feel there must be a way to emulate the browser 'back' button in Zope. Can anyone tell me if this is possible please ?
You can use <a href="javascript:history.go(-1)">Back</a>. But it won't work in browsers that don't support javascript.
You can do it without javascript, but you have to *do* it. HTTP is stateless, so the only way the REQUEST stuff can get forwarded is if you put it into the intermediate web page. That is, you have to make that continue button a form button, and put the current values of the variables in hidden data fields. Then your form has to have logic to recognize that it is being (re)called with values already set, and insert those values into the value fields of your form elements. If you go this route, instead of having a separate error page with a continue button, you might consider having the form be its own action, and have it redisplay with appropriate error messages and field highlights. This could potentialy provide a superior user experience... --RDM
