Hi to all. I have such situation i try to connect through the OAuth 2.0 protocol. I get access_token. and then i try to make facebook connection to use facebook API. But i recieve exception.
Code:
rg.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.web.client.ResourceAccessException: I/O error: No suitable constructor found for type [simple type, class org.springframework.social.facebook.api.FacebookProfile]: can not instantiate from JSON object (need to add/enable type information?)
 at [Source: java.io.ByteArrayInputStream@531602f4; line: 1, column: 2]; nested exception is org.codehaus.jackson.map.JsonMappingException: No suitable constructor found for type [simple type, class org.springframework.social.facebook.api.FacebookProfile]: can not instantiate from JSON object (need to add/enable type information?)

Maybe i have wrong configuration so here is my configs
Code:

	<bean id="textEncryptor" class="org.springframework.security.crypto.encrypt.Encryptors"

	<!-- <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

		<bean id="facebookWebArgResolver" class="org.springframework.social.facebook.FacebookWebArgumentResolver">

</beans>
Also i do not know what is #{request.userPrincipal.name}. Maybe i do not need userconnectionRepository at all.
