Grouper Users - Open Discussion List

["Waldbieser, Carl" <>]

I want to set the `Name_AttributeType` param value in my `sources.xml` so 
that it will show a subject's `displayName` attribute, or if that attribute 
is missing or blank it will show the `givenName` and `sn` attributes 
concatenated with a space.

I tried the following as the param-value, but the Grouper UI does not seem to 
like it:

  ${subjectUtils.defaultIfBlank(subject.getAttribute('displayName'), 
subject.getAttribute('givenName') + ' ' + subject.getAttribute('sn'))}

The UI shows me as logged in as "$SUBJECT_SOURCE - $SUBJECT_IDENTIFIER".  If 
I just use "displayName", it works fine for accounts that have that attribute.

Is my expression invalid?  Any advice?

Thanks,
