[jboss-user] [JBoss Seam] - Observer issues - multiple calls + async

[damianharvey]

I've just implemented the Manager Component pattern as outlined in the docs using @Unwrap and @Observer and it's working a treat. 

Two small issues with it though:

1. When using incremental hot deploy (ie. WEB-INF/dev) the Event is fired as many times as it's been since you last did a full deploy. For instance, if I start up my server and cause an event to fire, do an incremental hot deploy, cause the event to fire again; Then I will get the event firing twice on the second fire. If I do a full undeploy/redeploy it 'resets' the number of times it fires and all is good. 

2. Can @Observer be used with @Asynchronous? I've tried but I get the following exception:
  | Caused by: java.lang.NoSuchMethodException: java.util.ArrayList.rebuildTradeRoute()
  | 	at java.lang.Class.getMethod(Class.java:1581)
  | 	at org.jboss.seam.async.AsynchronousInvocation.call(AsynchronousInvocation.java:45)
If I remove the @Async then it's fine.

Cheers,

Damian.
