Isaac, At a certain stage it becomes pointless to stare at where the error is occurring (your mouseClicked()). We have to shift focus more on what it causing it in the first place.
Your scene graph would be quite an appropriate place to start! Are there only Cones in your scene graph or what else is in there? Would you please be so kind and list all the things you have in there? May be that will get us any further!
