I'm using the @Unwrap to return the logged in user entity (to avoid any lazy
initialization issues). However, when a user is not logged in I want the
@Unwrap method to return null, which I do, and seam ignores it.
Looking at the SeamVariableResolver class (below) line 44 correctly unwraps the
component to null. However, the variable resolver (line 46) interprets a null
value as the component not existing and then loads the seam component as a
managed bean (line 45).
Am I doing something wrong or is this a bug?
Thanks in advance, Peter.
