hello,
add the mixin type mix:lifecycle to a node and save the change.
after this I try to use the method Node.getAllowedLifecycleTransistions() and get the following exception:

javax.jcr.ItemNotFoundException: 5fd7d7f1-ceff-4b71-9df9-527702933b65/{http://www.jcp.org/jcr/1.0}lifecyclePolicy

	at org.apache.jackrabbit.core.NodeImpl.getProperty(NodeImpl.java:1171)
	at org.apache.jackrabbit.core.NodeImpl.getAllowedLifecycleTransistions(NodeImpl.java:3431)

does anyone have an idea what goes wrong?
is there anywhere more documentation about JCR liefcycle management available?

best regards.
