[jboss-user] [jBPM] - Re: Storing a long String (>255 Characters) in a Process Variable is not Possible(?)

Silvio Meier [http://community.jboss.org/people/k0k0pelli] created the discussion "Re: Storing a long String (>255 Characters) in a Process Variable is not Possible(?)" To view the discussion, visit: http://community.jboss.org/message/596150#596150 -------------------------------------------------------------- To illustrate the problem, I attached a simple dummy test. After deploying  it (execute the deploy class) and istantiating (using the class CreateInstance) a process with a test variable (testvar) that should be stored in a long text field  is created. the acutal code looks as follows: ProcessEngine processEngine = new Configuration().setResource("jbpm.cfg.xml").buildProcessEngine(); RepositoryService repositoryService = processEngine.getRepositoryService(); ExecutionService executionService = processEngine.getExecutionService(); Map<String, Object> variables = new HashMap<String, Object>(); variables.put("testvar", "This is a test variable for a text".toCharArray());        executionService.startProcessInstanceByKey("test", variables);    After  creating the instance with the long text variable testvar, the following exception occurs: Caused by: java.lang.ClassCastException: [C cannot be cast to java.lang.String     at org.hibernate.type.TextType.toString(TextType.java:94)     at org.hibernate.type.NullableType.nullSafeToString(NullableType.java:117)     at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:158)     at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:131)     at org.hibernate.persister.entity.AbstractEntityPersister.dehydrate(AbstractEntityPersister.java:2015)     at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2261)     at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2678)     at org.hibernate.action.EntityInsertAction.execute(EntityInsertAction.java:79)     at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:279)     at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:263)     at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:167)     at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:321)     at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:50)     at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1028)     at org.jbpm.pvm.internal.tx.HibernateSessionResource.prepare(HibernateSessionResource.java:56)     at org.jbpm.pvm.internal.tx.StandardTransaction.commit(StandardTransaction.java:107)     at org.jbpm.pvm.internal.tx.StandardTransaction.complete(StandardTransaction.java:64)     at org.jbpm.pvm.internal.tx.StandardTransactionInterceptor.execute(StandardTransactionInterceptor.java:57)     at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.executeInNewEnvironment(EnvironmentInterceptor.java:53)     at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.execute(EnvironmentInterceptor.java:40)     at org.jbpm.pvm.internal.svc.RetryInterceptor.execute(RetryInterceptor.java:56)     at org.jbpm.pvm.internal.svc.SkipInterceptor.execute(SkipInterceptor.java:43)     at org.jbpm.pvm.internal.svc.ExecutionServiceImpl.createVariables(ExecutionServiceImpl.java:174) I didn't find an open issue in the ticket tracker.
