Key: ORCHESTRA-52

Project: MyFaces Orchestra
Issue Type: Bug
Components: Conversation
Affects Versions: 1.4
Environment: tomcat 6.0.16
Reporter: Leonardo Uribe
Assignee: Leonardo Uribe
Doing some tests I saw this exception:
java.lang.ClassCastException: java.lang.Integer cannot be cast to
org.apache.myfaces.orchestra.conversation.ConversationManager

The line that causes this error is this:
if (cmObj == DUMMY)
It seems to be a workaround for Tomcat 6.0.16 at least, but by some unknown
reason, after some time this comparator stop working. This is a similar issue
as the one we had with FacesCompositeELResolver.SCOPE.
Note reproduce this one is difficult, but fortunately the solution is simple:
if (DUMMY.equals(cmObj))
