Description Karen Butzke CLA 2010-05-21 09:37:31 EDT 
Create the following Entity with the JPA Details view open.
Select the @TableGenerator annotation and choose the Quick Fix 'Add missing attributes'. You'll get an NPE.  No real side effect to this, just a logged NPE, if you type in a name the table generator name text field updates without problems.

@Entity
public class Employee {
    @Id
	@TableGenerator
	@SequenceGenerator
	private int id; 
}

Comment 1 Nan Li CLA 2010-11-18 11:32:07 EST 
Similar exception is thrown when first clicking the drop-down arrow of the 'Generator name' list of 'Primary key generation' in the JPA Details view, and then choosing another mapping in the JPA Structure view. A fragment of the exception is as the following:

java.lang.NullPointerException
