I've just started using PR3 of Webflow (nice stuff!!) and I'm trying to
get the redirect views to work.
It seems to be choking though on the following entry:
<end-state id="redirect"
view="redirect:${flowScope.service}?ticket=${flowScope.ticket}"/>
Is the above a valid statement? It seems to not be evaluating the
flowScope.service.
This is the error I get:
javax.servlet.ServletException: Could not resolve view with name
'redirect:${flowScope.service}' in servlet with name 'cas'
Thanks
-Scott

Yes, that's a limitation of the current RedirectViewDescriptorCreator: it
only evaluates expressions in the values of request attributes. That will
certainly be made more generic with the next release.
For now you could do something like this:
<end-state id="redirect" view="class:com.my.CustomViewDescriptorCreator"/>
and just implement a CustomViewDescriptorCreator for your case.

Erwin,
Thanks for the response.
One more question for you: is it possible to redirect to a specific url
(rather than a view). I tried creating a custom view descriptor creator
that did the following:
public class RedirectViewDescriptorCreator implements
ViewDescriptorCreator {
public ViewDescriptor createViewDescriptor(RequestContext
requestContext) {
final String service = (String)
ContextUtils.getAttributeFromFlowScope(requestContext,
WebConstants.SERVICE);
final String ticket = (String)
ContextUtils.getAttributeFromFlowScope(requestContext, WebConstants.TICKET);
final Map model = new HashMap();
model.put(WebConstants.TICKET, ticket);
ViewDescriptor descriptor = new ViewDescriptor(service, model);
descriptor.setRedirect(true);
return descriptor;
}
}
However, I get a an error message: javax.servlet.ServletException: Could
not resolve view with name
'redirect:https:/<machinename>:8443/contacts-cas/j_acegi_cas_security_check'
in servlet with name 'cas'
Is there a proper way to handle redirects to URLs using Webflow?
Thanks
-Scott

This is caused because of the ViewResolver(s) you have registered with the
DispatcherServlet. You don't seem to be using a UrlBasedViewResolver (e.g.
InternalResourceViewResolver), which picks up on the redirect.
Here's what's happening: I assume the value of the *service* string is
"https:/<machinename>:8443/contacts-cas/j_acegi_cas_security_check". Since
you are setting the redirect property of the view descriptor to true, the
FlowController.toModelAndView() method will actually create a ModelAndView
object with as a view name
"redirect:https:/<machinename>:8443/contacts-cas/j_acegi_cas_security_check".
This ModelAndView is passed back up to the DispatcherServlet which tries to
resolve it using a ViewResolver, as usual in Spring MVC. If you have a
UrlBasedViewResolver, it will recognize the "redirect:" prefix and construct
an appropriate RedirectView to redirect to the specified URL.
