validation error

Description of problem:
I have a valid (according to the validation available in the GUI) Work Item Definition - the .wid file you get with a new (first) .bpmn2 process, called WorkDefinitions.wid.
If I create a column that should execute a Work Item and check it in a row, I get this on validation:

Unable to Analyse Expression 
org.kie.internal.process.instance.WorkItemManager wim = (org.kie.internal.process.instance.WorkItemManager) drools.getWorkingMemory().getWorkItemManager(); org.kie.internal.process.instance.impl.WorkItemImpl wiLog = new org.kie.internal.process.instance.impl.WorkItemImpl(); wiLog.setName( "Log" ); wiLog.getParameters().put( "Message", "AAARGH!" ); wim.internalExecuteWorkItem( wiLog );: [Error: unknown class or illegal statement: org.mvel2.ParserContext@297f08b1] [Near : {... orkItemManager wim = (org.kie.internal.process.ins ....}] ^ [Line: 4, Column: 0]
