Make layer visible after LayerList widget has opened

[RyanStrain]

I have a subLayer, "Parcels_9562_6",  within a group layer that I need to programmatically make visible, after the LayerList has already opened.  Another widget communicates with the LayerList widget during user interaction. I've had no success while fiddling around with the LayerList widget's, Widget.js and LayerListView.js files. Does someone know how this can be accomplished? Thanks.

Allistair,

   In the edit widget you add this:

this.publishData({
  message: Some var you want to send
});
