Hi,

I repeated the entire exercise of creating an attribute,
giving it a name, and then attempting using WS to assign an
attribute/value combination to a stem and it worked.

Reviewing my work from the first attempt, I think I know what
I did wrong. I accidentally assigned an attribute def name that
was the same as the attribute def. They ended up with
different uuids, but the same "label":

gsh 9% a = 
AttributeDefNameFinder.findByName("Communities:LVC:LSC:MOU:mouFullName", 
true);
edu.internet2.middleware.grouper.attr.AttributeDefName: 
AttributeDefName[name=Communities:LVC:LSC:MOU:mouFullName,uuid=bf42403a350b4649862b776f3dac660f]
gsh 10% b = 
AttributeDefFinder.findByName("Communities:LVC:LSC:MOU:mouFullName", true);
edu.internet2.middleware.grouper.attr.AttributeDef: 
AttributeDef[name=Communities:LVC:LSC:MOU:mouFullName,uuid=1699c74ba9124509b5dfa5e609a6017f]

So the solution is "don't do that".

Perhaps the API should have thrown an error/warning when I
gave an attribute def name the same 'label' as the attribute
def?

Thanks,

Scott
