Redirects In Java base flow

[curtney]

Greetings!

I upgraded to Preview 5 and it seems the old way of doing a redirect in a Java base flow has change. What is the correct way of handling redirects now?

How are you doing redirects ATM?

[curtney]

In preview 3, you accomplish a redirect in a java base flow by doing the following:

new RedirectViewDescriptorCreator ("XXXXXXXXX);


In preview 5 the above class is no longer available. I have looked at the API, but I don't see how this can be done now. Also, I don't have access to "*.binding.Expression" API which appears to be what I need now. There is no link to this API.

In PR5 you still have the RedirectViewDescriptorCreator, however it is in the org.springframework.webflow.support package. So basically you could do:

new ViewState(getFlow(), stateId, new RedirectViewDescriptorCreator("/viewName?param0=value0&param1=value1"), transitions, properties);

Or alternatively:

addViewState(stateId, "redirect:/viewName?param0=value0&param1=value1", transitions, properties);

The binding library comes in the spring-binding-....jar file which is included in the SWF distribution. Source code is also included.

Thanks Erwin,

Erwin, I checked the api again, under support, and it is not there. Also, I checked the pr5 jar and was unable to find the class. Do I have to download a separate jar?

Sorry, my mistake. In PR5 the class is actually a static inner class of the TextToViewDescriptorCreator:

org.springframework.webflow.TextToViewDescriptorCr eator.RedirectViewDescriptorCreator

Check the JavaDoc of TextToViewDescriptorCreator for details: http://static.springframework.org/sp...orCreator.html

"addViewState(stateId, "redirect:/viewName?param0=value0&param1=value1", transitions, properties);" should still work though...

We've rearranged packages a bit for the next RC1 release to make classes more accessible.
