Custom TableView.CellRenderer

[Edgar Merino]

Hello,  

   I've tried to create a custom CellRenderer by extending a FlowPane 
(test code below), however none of the components inside the container 
are painted, I've tried to look at the code but I don't see why it 
wouldn't paint (in the end, it ends up calling CellRenderer#paint(), 
which turns out to be FlowPane#paint()). Maybe I missed something? I 
tried with other components like ImageView and it rendered without 
problem, any hint?

NOTE: tableData is not actually important in this test code, only length is
