Re: [Wicket-user] After redirection doRender() still called
you could use an IAuthorizationStrategy to perform a check at the constructor of your page. This is from the java doc /** * Authorization strategies control on a low level how authorization is implied. * A strategy itself is generally not responsible for enforcing it. What a * strategy does do is tell the framework whether a component may be created * (especialy usefull for implementing secure bookmarkable pages and components * that should always be secure no matter what environment they are put it), * whether it may be rendered (which can result in components being 'filtered' * from a page, or triggering the page to not be rendered at all and redirecting * to a error or logon page), and whether a component may be enabled (thus * controlling it's reachability etc) at all. * * @author Eelco Hillenius * @author Jonathan Locke */ The only catch is that you specify the strategy application wide so your strategy will be called for every component you create (not just pages). This is ofcourse not a big problem, just something i would like to see changed (just in case you are reading this eelco ;)) 2005/12/22, John Patterson <[EMAIL PROTECTED]>: > Hi Wicketeers, > > I have a page which can only be viewed if the user is logged in.

Re: [Wicket-user] After redirection doRender() still called
Also - more work, but ultimately the most flexible, is to provide your own request target resolving. The checkAccess method is a convenience method, but you can decide to put that kind of logic somewhere else too. See IRequestCycleProcessor and work your way down from there.

Re: [Wicket-user] After redirection doRender() still called
in 1.2 checkAccess() is not called in doRender any more but before it.But ofcourse the constructor is always called. If you don't want that then you need some kind of factory.What you could do is do the construction in the checkAccess() method but dont know if that is very nice way.. johanOn 12/22/05, John Patterson <[EMAIL PROTECTED]> wrote: Hi Wicketeers,I have a page which can only be viewed if the user is logged in.

Bookmarkable pages are the only one that come into my mind.

[Wicket-user] After redirection doRender() still called
Hi Wicketeers, I have a page which can only be viewed if the user is logged in. If the user is not logged in then checkAccess() redirects to a sign in page and returns false. I moved my "page building" code to the onBeginRequest() method so that it is only called when it is really needed (ie not when the page cannot be viewed). However, in my original page doRender() is still called and the html is parsed etc. This involves looking up data from the database which is never shown. Is there any way to build a page that will only be built if it is actually going to be displayed? Thanks, John. --- This SF.net email is sponsored by: Splunk Inc.
