What I wnat to do is: | | In the temporary object: | | try: | h=open('file',r) | except: | em = 'File %s does not exist' % file | return REQUEST.RESPONSE.redirect(self.manage_editSettings(REQUEST), em) redirect should take a URL (i.e. a string), not a rendered page... | the calling Object then would pass it to the browser ... | | ... in order to do some exception handling. | | is there an other way to redirect to the settigs Form when an error occurs in this nonpersistent object? Since your class is already assuming things (manage_editSettings e.g.), a) pass in a parent object that is wrapped and call parentObj.manage_editSettings.. b) or more cleanly call parentObj.errorOccurred(message) which would do the redirect, c) or even more cleanly you could raise an exception, and catch it in the parent class, then redirect. -- Andrew Milton akm@theinternet.com.au
