Subject svn commit: r658240 - in /activemq/camel/trunk: camel-core/ camel-core/src/main/java/org/apache/camel/impl/ camel-core/src/main/java/org/apache/camel/management/ camel-core/src/main/java/org/apache/camel/model/ camel-core/src/main/java/org/apache/camel...
Date Tue, 20 May 2008 13:25:01 GMT
Author: jstrachan
Date: Tue May 20 06:25:00 2008
New Revision: 658240

URL: http://svn.apache.org/viewvc?rev=658240&view=rev
Log:
changed the interceptor code to separate adding an interceptor for a node in the DSL from
adding an interceptor to future steps added to the node; ideally we need to refactor further
to avoid confusion (maybe splitting the uses of IntereceptorType into 2 different types).
Have temporarily disabled the MulticastStreamTest until I figure out how to fix it :)
