问题 I'm using a StreamProvider in flutter to listen to my firebase collection. The stream works correctly however since I'm passing down the value of the stream provider to other child widgets(all of which are stateless) the child widgets don't rebuild even though the stream is correctly updated. This is my stream provider StreamProvider<List>.value( value: ChatService(shadeUID: widget.poll.shadeUID, pollUID: widget.poll.uid).threads, child: ThreadsList(poll: widget.poll, shadowUID: widget

Same like Per Session this will work with all bindings except basicHttpBinding. InstanceContextMode.Single not available for basicHttpBinding. But according to this answer it works. This article adds confusion. I'd like to get clear answer and explanation. 回答1: InstanceContextMode.Single will force the WCF engine

问题 I have a J2EE REST-based app using Spring Security 4.0.1.RELEASE. Needless to say, Spring documentation on sessionCreationPolicy and sessionFixation is sparse, aside from targeted questions here on StackOverflow. I'm using a Java-based config for Spring Security like this: @Configuration @EnableWebSecurity @EnableGlobalMethodSecurity(secureEnabled=true, prePostEnabled=true, jsr250Enabled=true, order=1) public class DefaultSecurityBeansConfig extends WebSecurityConfigurerAdapter { @Override
