Grouper Users - Open Discussion List

[Peter DiCamillo <>]

I'm having a problem with the descriptions generated for external users. 
In grouper.properties, there is this expression for generating the 
description:

> externalSubjects.desc.el = [unverifiedInfo] 
> ${grouperUtil.appendIfNotBlankString(externalSubject.name, ' - ', 
> externalSubject.institution)} [externalUserID] ${externalSubject.identifier}

That expression seems to work fine when the institution was specified on 
the registration screen. However, if the institution is left empty on 
the form, the term 
${grouperUtil.appendIfNotBlankString(externalSubject.name, ' - ', 
externalSubject.institution)} doesn't work as intended. Instead of 
evaluating to just the subject name, it comes out in the description as 
"null". For example, a description like this:

>  [unverifiedInfo] null [externalUserID] 
>
>  is a direct member

I tried a few possibilities for fixing this, but always got "null".
