Hi, I would like to hear the Turbine users' opinion on something before I go ahead and do something stupid. ;)
I had a look at the way Scarab uses the 'nextTemplate' parameter to determine which template to display next if an action executed successfully. We have been using this approach for a few months now. One problem is that the user can use the 'refresh' button to execute the action again. I know this can be detected using the "_session_access_counter" and we are using this on a few pages in our application. The second problem is that using the browser's 'back' button to return to the post action page will cause a post method form to be resubmitted (if there was one) or at least cuase the browser to prompt the user, informing him of this fact. There are certain pages in our application that we want to be able to reload without executing the action again. We also want the user to be able to use the back button to return to the page without executing the action again or re-submitting the form. To achieve this, I constructed a new URL in the action class by removing the 'action' parameter and setting the 'template' parameter to the value of the 'nextTemplate' parameter, retaining the rest of the original URL: e.g. http://my.application.com/action/testAction/template/templateOne/nextTemplate/templateTwo/someParameter/someValue becomes: http://my.application.com/template/templateTwo/someParameter/someValue I then do a data.getResponse().sendRedirect() using the second URL at the very end of the action. The result is that the action is executed and the user is presented with a page that is 'refresh safe' and that he can navigate back to using the browser's back button. I suppose the main difference between doing a redirect and using something like the 'nextTemplate' parameters is that user A can look at the post action page and decide to mail the link to user B, who can then use the link to open the page and see exactly the same thing as user A did. Can anybody foresee any problems with this appoach? Is there a significant time delay in doing a redirect? Will Turbine's context be re-populated and the tools reinitialized for the redirect? Thank you for your time. Regards. - Johnny. -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
