Hi, I have tried various ways to accomplish this, so far with limited success, any pointers would be appreciated :-) Here is my scenario: - a user fills in a web form on a non-Pier web site - the form is submitted via HTTP post to a URL on the Pier site, like so: http://the.piersite.net/seaside/pier?command=DoSomething - DoSomething is a PRCommand that requires a login - the user logs in - Pier shows a confirmation form that summarizes the data from the original form - user clicks OK - DoSomething is executed - Pier shows the home page of the user http://the.piersite.net/seaside/pier/accounts/joeuser?command=PRViewCommand I can have DoSomething execute successfully, but I cannot make the change to the users home page. Maybe my approach is wrong: - I use Seaside 2.7b with the latest Pier, Magritte etc - I use Pier Unix security - DoSomething is a PRCommand that implements isValidIn: aContext on the class side as aContext isLoggedIn. This, together with configuring PUPierMain as the main class will invoke the on-the-fly login. - I have a made a patch to PRPierMain>>commandFrom: such that the newly created PRCCommand will have a chance to read additional data from the external HTTP Request (inside DoSomething>>processRequest:) - DoSomething answers a custom subclass of WAComponent (say, ConfirmView) in its asComponent method - the ConfirmView knows the DoSomething command so it can display the users data, with a button "Confirm". Clicking the Confirm button will send the message confirm to the view ConfirmView>>confirm command user: self context user.. command execute - I can see that the command executes successfully. Inside DoSomething>>execute I have self answer: (self context structure: self user account "account is a PRStructure" view: UserAccountView) - I have inspected the command at this point, and answer gets the right contents. - However, when I click on the button, the Confirm view just stays there. Do you see any chance to get this working? I have tried to look at Pier Blog and others, but they all seem to use #answer: without problems. I'd be thankful for any hints, or alternative ways to achieve the page flow I described. Cheers Matthias
