FlowHandler.handleExecutionOutcome sendRedirect not working for mvc portlet for external redirect [SWF-1551]
kaushal desai opened SWF-1551 and commented
This is related to #1531, where the suggestion is to override FlowHandler.handleExecutionOutcome method and use ActionResponse.sendRedirect for end-state.
When same is implemented, following exception stack trace is generated:
00000611 SystemErr R java.lang.IllegalStateException: Can't invoke sendRedirect() after certain methods have been called

The booking-portlet-mvc samples doesn't do a redirect but you can experiment. It would be useful if you could isolate whether the issue is linked to Web Flow or your portlet container. For example does it work in Apache Pluto or other you can try with? Have you tried redirecting in your own portlet container without Web Flow?
