Getting: You may need to switch newer MVC infraestructure

[jdmr]

I'm getting the following error when I try to get to the action mapping method on a controller after clicking a button that sends me there. Here's the exception >

java.lang.IllegalStateException: Argument [RedirectAttributes] is of type Model or Map but is not assignable from the actual model. You may need to switch newer MVC infrastructure classes to use this argument.

What am I missing?

Thank you very much for your help...

Judging from your code you are mixing portlet and servlet packages. The RedirectAttributes are from the servlet package whereas you are using/creating a Portlet. I suspect that RedirectAttributes doesn't work for a Portlet environment.

Could you post the full stacktrace/log?

[rohan123]

Hi,

You can't you Redirect Attribute in Portlet Environment. Read below(which i copied from here):

RedirectAttributes (Servlet-only, @MVC 3.1-only) to specify the exact set of attributes to use in case of a redirect and also to add flash attributes (attributes stored temporarily on the server-side to make them available to the request after the redirect). RedirectAttributes is used instead of the implicit model if the method returns a "redirect:" prefixed view name or RedirectView.

Also for Marten: I have replicated this issue at my end. Attaching log for same.

[jdmr]

So I cannot use RedirectAttributes inside Portlets... Thanks... I got it...
