Retrieving custom attribute values of a work item

Can some one let me know how to get the custom attribute values?


I'm doing this

List<IAttributeHandle> attrHandles= workItem.getCustomAttributes();
int size = attrHandles.size();
for(int i=0; i<size;i++)
{
IAttributeHandle handle= attrHandles.get(i);
IItem attrItem = repositoryItemService.fetchItem(handle, null);
IAttribute attribute = (IAttribute) attrItem;

System.out.println(attribute.getAttributeType());
System.out.println(attribute.getIdentifier());
Object value= workItem.getValue(attribute);

System.out.println("value"+ value);
}


Output is

size is2
Category
skill
valuecom.ibm.team.workitem.common.model.ILiteral:Category.literal.l1
Role
Role
valuecom.ibm.team.workitem.common.model.ILiteral:Role.literal.l1

As you see from the output. workItem.getValue(attr) does not return the actual value stored for that attribute.Custom attributes here are enumerations. Any thing specific to be done to get the attr values in this context?
