I  using Mule 2.2 and jBPM 3.2.7. And at the end of the process during  persisting  the variable instance within the process I get the following  errors

ERROR  2010-11-28 15:23:41,515 [jBpmConnector.dispatcher.1]  org.mule.DefaultExceptionStrategy: Caught exception in Exception  Strategy: *variable 'incoming' in 'TokenVariableMap20224a'  contains 'ACKNOWLEDGED': type 'java.lang.String' is unpersistable  according to the jbpm.varmapping.xml configuration*

**************

why would java.lang.String be an instanceof UnpersistableInstance?
Where will have defined?

I have reviewed the jbpm.varmapping.xml

PS: i have also updated an existing thread at  http://community.jboss.org/573273#573273 http://community.jboss.org/message/573273#573273


help??
