Subject [jira] Commented: (CHAIN-12) [chain] ContextBase throws NotSerializable exception for PropertyDescriptor
Date Thu, 25 May 2006 02:51:53 GMT
    [ http://issues.apache.org/jira/browse/CHAIN-12?page=comments#action_12413207 ] 

Niall Pemberton commented on CHAIN-12:
--------------------------------------

Marking them as transient would get rid of the serialization exception, but unless theres
some smart way of getting hold of the wrapped container objects (request, context etc.) when
a WebContext implementation is de-serialized then it just moves the problem along.
