WSRP producer as 2-node cluster with loadbalancer - registration issue

             Project: GateIn WSRP
          Issue Type: Task
          Components: Producer
    Affects Versions: 2.1.0-Beta08
         Environment: EPP5.2.0 ER05
            Reporter: Michal Vanco
            Assignee: Chris Laprun
             Fix For: 2.1.0-CR01


Imagine/configure the environment: producer as 2-node cluster with loadbalancer + 1 consumer.
You register new consumer at consumer node with WSDL from loadbalancer. Loadbalancer points to one of nodes (let's wait node1) and registration is done with node1.

btw. WSDL on loadbalancer directly points to one of nodes (there is node1 or node2 at all URLs)

You put some remote portlet on page (communication is between consumer+node1 through loadbalancer), do failover - stop node1.
At this moment you would expect that remote portlet is still available, but it's not because consumer is registered with node1.
It means that after refresh of page with remote portlet -> portlet is not displayed.

You have to go to WSRP admin and refresh consumer (with WSDL of loadbalancer), now the question:
 - what is expected at this moment? Registration on second node? (this should be somehow distributed from killed node)
 - when you have 2 cluster nodes started on one machine - you can't continue and refresh won't be successfull (Could not transmit message, Can not connect http client invoker after 1 attempt(s)) - this should be related to unique consumer name registration on producer
 - when you have 2 nodes started on different machines - you should be able to refresh, what happens with registration? Is there new registration with second node? What happens when node1 is back? (2 different registrations for same consumer?)

At this moment I've tested 2 nodes at same machine - at this scenario you can't continue using remote portlet and refresh consumer after failover.

I can provide some more details based on reply of expected behavior.
Thanks!
