The following model causes an error org.clafer.ast.analysis.TypeException: Cannot join abstract c0_Port . parent:

abstract Component
    abstract Port
    allPorts -> Port *
    // query for all nested ports explicitly
    [ all p : Component.Port | p.parent=this <=> p in this.allPorts ]   // p.parent causes the error

WinController : Component
    cmd : Port
    powerOut : Port

where, in fact, Port has a parent because it is nested under Component.
