Bundles not working properly?

[On latest Chisel, FIRRTL, etc.]

Can anyone see if there's anything wrong with the code here? https://github.com/ucb-art/Chisel3DSPExample/blob/master/src/test/scala/UsefulExamples/SimpleTBwGenTypeOption.scala

Relevant code:

class DataTypeBundle[R <: Data:Real](genType: R, width: Width, binaryPoint: BinaryPoint) extends Bundle {
  val gen = genType.chiselCloneType
  val s = SInt(width)
  val f = FixedPoint(width, binaryPoint)
  val u = UInt(width)
  override def cloneType: this.type = new DataTypeBundle(gen, width, binaryPoint).asInstanceOf[this.type]
}

class Interface[R <: Data:Real](genShort: R, genLong: R, includeR: Boolean, p: TestParams) extends Bundle {

  val smallW = p.smallW.W
  val bigW = p.bigW.W
  val smallBP = p.smallBP.BP
  val bigBP = p.bigBP.BP
  val vecLen = p.vecLen

  val r = if (includeR) Some(DspReal()) else None
  val b = Bool()
  val cGenL = DspComplex(genLong)
  val cFS = DspComplex(FixedPoint(bigW, smallBP))
  val cR = DspComplex(DspReal())

  val short = new DataTypeBundle(genShort, smallW, smallBP)
  val long = new DataTypeBundle(genLong, bigW, bigBP)

  val vU = Vec(vecLen, UInt(smallW))
  val vS = Vec(vecLen, SInt(smallW))  
  
  override def cloneType: this.type = new Interface(genShort, genLong, includeR, p).asInstanceOf[this.type]
}

TestParams is a case class.

The IO inside my module looks like this:

 val io = IO(new Bundle {
    val i = Input(new Interface(genShort, genLong, includeR, p))
    val o = Output(new Interface(genShort, genLong, includeR, p)) }) 

The particular reflection error is this:

OK, @sdtwigg helped me debug (and might PR a change later?) It was unhappy that I had a parameter called "width"... getPublicFields of the bundle resulted in

WrappedArray(public chisel3.core.FixedPoint SimpleTB.DataTypeBundle.f(), public chisel3.core.SInt SimpleTB.DataTypeBundle.s(), public chisel3.core.UInt SimpleTB.DataTypeBundle.u(), public chisel3.internal.firrtl.Width chisel3.core.Aggregate.width())

Last line, like what? -_-
