Comment 4 Samaresh Panda 2006-08-10 18:23:31 UTC 
The schema model returns null when I call component.getRef().get() on the
following attribute reference:

<xsd:attribute ref="xml:lang"/>

See line 133 in j2ee_1_4.xsd.
Comment 5 Nam Nguyen 2006-08-10 19:24:06 UTC 
Sam,
Whatever cause getRef().get() to return null, the NPE still need to be fix. 
There are user conditions (could not resolve imported models) that
reference.get() will return null.
The other part, fail to resolve 'xml:lang' could be different bug or enhancement.
Comment 6 Samaresh Panda 2006-08-10 20:26:40 UTC 
Fix integrated:
AXIComponentCreator.java: new revision: 1.1.2.10;

However, note that, DV will not be able to display this attribute-reference,
since the referent doesn't exist. In DV, no distiction is made between
Attribute, AttributeRef and Element, ElementRef.

You may want to create a separate bug.
