Grouper Users - Open Discussion List

I don't think that is a problem, things with different types can have the 
same name (groups, folders, attributeDefs, attributeDefNames, etc).  However, 
pre 1.6.2 if you have attribute defs that can be assigned to various types of 
objects, it was a problem.  Can you use 1.6.2?

Thanks,
Chris

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
