I am successful using ArrayList as a delegation parameter in an Assignment. I tried a HashMap, but so far it is not assigned, always null.

I'm using jbpm-jpdl-3.2.GA version, are there any known problems with Maps?

My successful ArrayList is processusercodingfields in the code below. The unsuccessful HashMap is processcodingfieldvalues.

<task name="Officer - Add Record Holds" blocking="true">
 <assignment class="com.rco.bpm.assignment.GeneralTaskAssignment">
 <currentStep>Officer - Add Record Holds</currentStep>
 <roles>Record Officer</roles>
 <processusercodingfields>
 <element>UserComment</element>
 <element>Promise Date</element>
 <element>Due Date</element>
 </processusercodingfields>
 <processcodingfieldvalues>
 <entry><key>RMS Stat Description</key><value>Number Destroyed</value></entry>
 </processcodingfieldvalues>
 </assignment>
 </task>

public class GeneralTaskAssignment implements AssignmentHandler
{
 private static final long serialVersionUID = 1L;
 private static final Log log = LogFactory.getLog(GeneralTaskAssignment.class);

 private String roles = null;
 private String currentStep = null;
 private boolean bIncludeRolesWithBlankRole = false;
 private boolean bIncludeRolesWithBlankOrg = false;
 private boolean bIncludeRolesWithBlankSubOrg = false;
 private boolean bIgnoreRole = false;
 private boolean bIgnoreOrgNum = false;
 private boolean bIgnoreSubOrgNum = false;
 private String orgNumsOverride = null;
 private String subOrgNumsOverride = null;
 private String actorcodingfieldname = null;
 private String statdescription = null;
 private ArrayList processusercodingfields = null;
 private HashMap processcodingfieldvalues = null;

 public void assign(Assignable assignable, ExecutionContext executionContext)
 throws Exception
 {
 CAssignment.IAssignablePlus assignableplus = new CAssignment.AssignableTask(
 assignable);
 CAssignment.assign(
 assignableplus,
 executionContext,
 this.currentStep,
 processusercodingfields,
 processcodingfieldvalues,
 actorcodingfieldname,
 this.roles,

 false,
 this.bIncludeRolesWithBlankRole,
 this.bIncludeRolesWithBlankOrg,
 this.bIncludeRolesWithBlankSubOrg,
 this.bIgnoreRole,

 this.bIgnoreSubOrgNum);
 }

}
