OK, now I know what changed. The bijected variables of the outer class *only* have well-defined values during a method call to the outer class! They do not have well-defined values after the invocation ends. To enforce this, Seam now nullifies injected variables at the end of the invocations. So the following will not work: foo.getInnerClass().bar() Of course, you could have getInnerClass() construct a new instance of InnerClass, and initialize its instance variables to the value of the bijected variables in the constructor.
