Hi, MessageStoreInterceptor is very handy in preserving error messages. This is very useful in POST-REDIRECT-GET pattern. An action handling POST can store action errors which are available for action/view processing GET request after POST.Many times we also need to preserve values entered by user on the form which caused action errors. Therefore it will be useful to have something likeModelStoreInterceptor which preserves model across requests and makes it available on value stack. Anyone knows if this is written already?
