Hi @shilpajh - can you try this with the development branch of Flux? Although I'm not completely sure, it could be fixed by a recent commit 1927968 which causes the correct controller name to be used. An incorrect controller name could be the reason why no request is returned from getRequest which appears to be why you receive this error.

The underlying cause of this problem appears to be that one or more of your template files do not contain a flux:form definition and/or do not contain the Configuration section. So you should be able to avoid the problem - but of course the fallback case that throws this error should still be fixed.
