The example given in 8.2 is incomplete and erroneous.  On page 73 CRMConfigurator.getTypeId() returns "CRMConfig" but on page 74 the (unspecified!) operator's getParameterTypes() invokes new ParameterTypeConfigurable with a third argument of "crmconfig".  This will fail with a trace similar to this: 

Nov 16, 2012 3:51:43 PM com.rapidminer.tools.OperatorService parseOperators
WARNING: Failed to register operator: rmx_CRM*** : crm_***
com.rapidminer.operator.OperatorCreationException: Operator cannot be constructed: 'crm_***(com.rapidminer.operator.***)': Unknown configurable type: crmconfig
	at com.rapidminer.operator.OperatorDescription.createOperatorInstance(OperatorDescription.java:354)
        ...
On pp. 71-72, the CRMConfigurable class needs to override getTypeId() in order to return "CRMConfig", right?
