Description htt 2006-08-25 20:45:26 UTC 
With trunk build 060824, jdk1.5.0_07...

open a new schema -> Design Pattern=VB
In Design view,
  d/d complex type ct1
  d/d element e1 to ct1
  d/d element e2 to e1 -> e1Type is generated
  change sequence of e1Type to all -> notice that e1 is now collapsed.  Expand
it: there're now 2 copies of e2.  (NOTE: Source view correctly shows only one e2
however.)
  delete one of the e2 -> e2 is deleted from Source & Design views
  delete the remaining e2 -> NPE

java.lang.NullPointerException

Addendum (to original Description): 
     d/d = drag and drop
     VB  = Venetian Blind
