R Source (Table) error message

When I tried to configure "R Source (Table)" node, sometimes I will get this error message and the dialog window would not open.

ERROR NodeContainerEditPart            The dialog pane for node 'R Source (Table) 0:2' has thrown a 'IndexOutOfBoundsException'. That is most likely an implementation error.

 

I observe the same behavior for this node as well as the other R nodes. This error happens routinely, but the fix is easy: simply double-click on the node again. Usually, the config window will open sucessfully after 2-3 tries.
