More on Listener Output

[Barry Denton]

I think there is more behind this than just escaping the brackets
The event does not return any item number or other stuff it should return It does get the type and the time, but no item,x,y,or data.

If you compile and run the program below you will see that the output when selecting a point on either table is nothing for any point on the table?
--------------------------------------------------------------------------------------
>>>Item is  TableItem {item 0  }
>>>Event {missing or misplaced '}'}Event {type=13 Table {} time=1857596828 data={null} x=0 >>>y=0 width=0 height=0 detail=0}
>>>This is where item details should be
>>>point is Point {0, 0}
