SAML authorization problem

Hello.

I have a problem setting up SAML authorization.

I have created a test XS aplication in my HAMA profile, I have configured Local service provider and Trusted identity provider, and after that I am trying to login using SAML authorization, but I recieve error all the time:

"HTTP Status 400 - Service Provider endpoint saml2/sp/acs could not redirect to original application URL because it has not received RelayState"

What could be the problem? Does I need somewhere to set up some king of linking with RelayState and my test application URL address?

My trial account  ID is "p1941225638trial"

Can anyone please help me out.

Thanks
