I'm using Oracle as my datasource and using jBPM in my own web application. I have the JBPM schema on Oracle with the JBPM_ID_GROUP table with 1 row for group 'DivisionHead'. When jBPM tries to assign the task to "group(DivisionHead)" I get the below errors: WARN QuerySplitter : no persistent classes found for query class: select g from org.jbpm.identity.Group as g where g.name = :groupName WARN RequestProcessor : Unhandled Exception thrown: class org.jbpm.graph.def.DelegationException 14:53:06,580 ERROR [[action]] Servlet.service() for servlet action threw exception java.lang.IllegalArgumentException: Parameter groupName does not exist as a named parameter in [select g from org.jbpm.identity.Group as g where g.name = :groupName] at org.hibernate.impl.AbstractQueryImpl.setParameter(AbstractQueryImpl.java:356) Anyone know whats wrong and how to fix it?
