I'm having the same issue, and have also followed all the directions in the documentation, the sole exception being that I had to add the @WebRemote annotation to the implementation, in addition to the local interface.

see JBSEAM-3459=>https://jira.jboss.org/jira/browse/JBSEAM-3459

change remote.js 

window.setTimeout(function() {
    asyncReq.onreadystatechange = function() {
    if (rcb) rcb(asyncReq, callback);     
    }
 }, 0);

to

//window.setTimeout(function() {
    asyncReq.onreadystatechange = function() {
    if (rcb) rcb(asyncReq, callback);     
    }
  //}, 0);

or

window.setTimeout(function() { 
  asyncReq.onreadystatechange = function() { 
  if (rcb) rcb(asyncReq, callback); 
  }; 
  asyncReq.send(envelope); 
}, 0);
