Need Help: JTable POP up menu in a CellEditor to display on a right click

Question

This was from a previous post:
I am trying to make a POP menu in a JTextComponent that has a assigned JEditorPane for a HTMLDocument to make use of the HTMLEditorKit to allow modifying HTML by the POP up menu.

I got the pop up to work, I had to go back to and add a createActionTable editor that is a JEditorPane, vs the JTextComponent!
