Hi all,
i'm trying to implement a domain specific task using following work definition

import org.drools.process.core.datatype.impl.type.EnumDataType;
[
  [
    "name" : "patientDataHandler",
    "displayName" : "Patient data",
    "parameters" : [
      "Operation" : new EnumDataType("careMgmt.domainSpecificTask.PatientDataOperations"),
    ],
    //"icon" : "icons/notification.gif"
  ]

]


but when i try to modify Operation's parameter in the properties of a patientDataHandler service task in the eclipse bpmn editor i have following error:


java.lang.IllegalArgumentException: Could not find data type careMgmt.domainSpecificTask.PatientDataOperations

i don't know because the editor can't find PatientDataOperations, in any project files i can use it.
does anyone know how to define a work item that accept as parameter a enum?

i have put in META-INF directory drools.rulebase.conf and patientDataHandler.conf which i attached.
i attach also the file that define enum

Thanks,
Francesco
