[jira] [Commented] (USERGRID-18) null pointer response when adding entity to collection by name

-----------------------------------------

Hi [~aweeraman], 

I was looking into https://issues.apache.org/jira/browse/USERGRID-94 and noticed that :
*Class:* org.apache.usergrid.persistence.Identifier.java
*Method:*  public static Identifier from( Object obj ) 
returns *null* if the type is not matched to a known type. This could cause a lot of problems as methods are performed on these null objects later on (saw a few loops doing this).

This might be the cause for this bug. Just a hunch. 
Hope this will save you some time ! 

Thanks and Regards, 
Malaka

> "This is an error handling issue that could be improved. When trying to add an entity to another collection mistakenly by name, a NPE is given. It would be helpful if the exception explained that uuid is needed instead of giving NPE. New users looking at the API could get confused by this.
